The SRAM can be read and written an infinite number of times, while independent, nonvolatile data resides in Nonvolatile Elements. Data transfers from the SRAM to the Nonvolatile Elements (the STORE operation) can take place automatically on power down. A 68-F or larger capacitor tied from VCAP to ground guarantees the STORE operation, regardless of power-down slew rate or loss of power from "hot swapping". Transfers from the Nonvolatile Elements to the SRAM (the RECALL operation) take place automatically on restoration of power. A hardware STORE may be initiated with the HSB pin.

This pin is not connected to the die VCAP NC Document #: 001-06727 Rev. *C Page 2 of 14 [+] Feedback PRELIMINARY Device Operation The CY22E016L nvSRAM is made up of two functional components paired in the same physical cell. These are a SRAM memory cell and a nonvolatile QuantumTrap cell. The SRAM memory cell operates as a standard fast static RAM. Data in the SRAM can be transferred to the nonvolatile cell (the STORE operation), or from the nonvolatile cell to SRAM (the RECALL operation). This unique architecture allows all cells to be stored and recalled in parallel. During the STORE and RECALL operations SRAM READ and WRITE operations are inhibited. The CY22E016L supports infinite reads and writes just like a typical SRAM. In addition, it provides infinite RECALL operations from the nonvolatile cells and up to 1 million STORE operations. CY22E016L 10k Ohm 1 28 27 26 68 UF 6v, +20% SRAM Read The CY22E016L performs a READ cycle whenever CE and OE are low while WE and HSB are high. The address specified on pins A0-10 determines which of the 2,048 data bytes will be accessed. When the READ is initiated by an address transition, the outputs will be valid after a delay of tAA (READ cycle #1). If the READ is initiated by CE or OE, the outputs will be valid at tACE or at tDOE, whichever is later (READ cycle #2). The data outputs will repeatedly respond to address changes within the tAA access time without the need for transitions on any control input pins, and will remain valid until another address change or until CE or OE is brought high, or WE or HSB is brought low. U 0.1 F Bypass 14 15 Figure 1. AutoStore(R) Mode 10k Ohm 10k Ohm SRAM Write A WRITE cycle is performed whenever CE and WE are low and HSB is high. The address inputs must be stable prior to entering the WRITE cycle and must remain stable until either CE or WE goes high at the end of the cycle. The data on the common I/O pins I/O0-7 will be written into the memory if it is valid tSD before the end of a WE controlled WRITE or before the end of an CE controlled WRITE. It is recommended that OE be kept high during the entire WRITE cycle to avoid data bus contention on common I/O lines. If OE is left low, internal circuitry will turn off the output buffers tHZWE after WE goes low. 1 28 27 26 AutoStore Operation During normal AutoStore operation, the CY22E016L will draw current from VCC to charge a capacitor connected to the VCAP pin. This stored charge will be used by the chip to perform a single STORE operation. After power up, when the voltage on the VCAP pin drops below VSWITCH, the part will automatically disconnect the VCAP pin from VCC and initiate a STORE operation. Figure 1 shows the proper connection of the storage capacitor (VCAP) for automatic store operation. A charge storage capacitor having a capacity of between 68 F and 220 F (20%) rated at 6V should be provided.In system power mode both VCC and VCAP are connected to the +5V power supply without the 68-F capacitor. In this mode the AutoStore function of the CY22E016L will operate on the stored system charge as power goes down. The user must, however, guarantee that VCC does not drop below 3.6V during the 14 15 U 0.1 F Bypass Figure 2. System Power Mode If an automatic STORE on power loss is not required, then VCC can be tied to ground and +5V applied to VCAP. This is the AutoStore Inhibit mode, in which the AutoStore function is disabled. If the CY22E016L is operated in this configuration, references to VCC should be changed to VCAP throughout this data sheet. In this mode, STORE operations may be triggered with the HSB pin. It is not permissible to change between these three options "on the fly". Document #: 001-06727 Rev. *C Page 3 of 14 10k Ohm [+] Feedback PRELIMINARY CY22E016L 10k Ohm 1 28 27 26 10k Ohm be scaled by the number of devices connected to it. When any one of the CY22E016L detects a power loss and asserts HSB, the common HSB pin will cause all parts to request a STORE cycle (a STORE will take place in those CY22E016L that have been written since the last nonvolatile cycle). During any STORE operation, regardless of how it was initiated, the CY22E016L will continue to drive the HSB pin low, releasing it only when the STORE is complete. Upon completion of the STORE operation the CY22E016L will remain disabled until the HSB pin returns high. If HSB is not used, it should be left unconnected. 0.1U F Bypass Hardware RECALL (Power-up) During power-up, or after any low-power condition (VCC < VSWITCH), an internal RECALL request will be latched. When VCC once again exceeds the sense voltage of VSWITCH, a RECALL cycle will automatically be initiated and will take tHRECALL to complete. Data Protection 14 15 Figure 3. AutoStore Inhibit Mode In order to prevent unneeded STORE operations, automatic STOREs as well as those initiated by externally driving HSB low will be ignored unless at least one WRITE operation has taken place since the most recent STORE or RECALL cycle. An optional pull-up resistor is shown connected to HSB. This can be used to signal the system that the AutoStore cycle is in progress. The CY22E016L protects data from corruption during low-voltage conditions by inhibiting all externally initiated STORE and WRITE operations. The low voltage condition is detected when VCC < VSWITCH. If the CY22E016L is in a WRITE mode (both CE and WE low) at power-up, after a RECALL, or after a STORE, the WRITE will be inhibited until a negative transition on CE or WE is detected. This protects against inadvertent writes during power-up or brown-out conditions. Noise Considerations The CY22E016L is a high-speed memory and so must have a high-frequency bypass capacitor of approximately 0.1 F connected between VCC and VSS, using leads and traces that are as short as possible. As with all high-speed CMOS ICs, careful routing of power, ground, and signals will reduce circuit noise. Hardware STORE (HSB) Operation The CY22E016L provides the HSB pin for controlling and acknowledging the STORE operations. The HSB pin can be used to request a hardware STORE cycle. When the HSB pin is driven low, the CY22E016L will conditionally initiate a STORE operation after tDELAY. An actual STORE cycle will only begin if a WRITE to the SRAM took place since the last STORE or RECALL cycle. The HSB pin also acts as an open drain driver that is internally driven low to indicate a busy condition while the STORE (initiated by any means) is in progress. SRAM READ and WRITE operations that are in progress when HSB is driven low by any means are given time to complete before the STORE operation is initiated. After HSB goes low, the CY22E016L will continue SRAM operations for tDELAY. During tDELAY, multiple SRAM READ operations may take place. If a WRITE is in progress when HSB is pulled low it will be allowed a time, tDELAY, to complete. However, any SRAM WRITE cycles requested after HSB goes low will be inhibited until HSB returns high. The HSB pin can be used to synchronize multiple CY22E016L while using a single larger capacitor. To operate in this mode the HSB pin should be connected together to the HSB pins from the other CY22E016L. An external pull-up resistor to +5V is required since HSB acts as an open-drain pull-down. The VCAP pins from the other CY22E016L parts can be tied together and share a single capacitor. The capacitor size must Low Average Active Power CMOS technology provides the CY22E016L the benefit of drawing significantly less current when it is cycled at times longer than 50 ns. Figure 4 shows the relationship between ICC and READ/WRITE cycle time. Worst-case current consumption is shown for both CMOS and TTL input levels (commercial temperature range, VCC = 5.5V, 100% duty cycle on chip enable). Only standby current is drawn when the chip is disabled. The overall average current drawn by the CY22E016L depends on the following items: 1. The duty cycle of chip enable. 2. The overall cycle rate for accesses. 3. The ratio of READs to WRITEs. 4. CMOS vs. TTL Input Levels. 5. The operating temperature. 6. The VCC level. 7. I/O loading. Document #: 001-06727 Rev. *C Page 4 of 14 [+] Feedback PRELIMINARY Preventing STOREs The STORE function can be disabled on the fly by holding HSB high with a driver capable of sourcing 30 mA at a VOH of at least 2.2V, as it will have to overpower the internal pull-down device that drives HSB low for 20 ns at the onset of a STORE.
