| IS62WV10248BLL 1M x 8 LOW VOLTAGE, ULTRA LOW POWER CMOS STATIC RAM FEATURES * High-speed access time: 55ns, 70ns * CMOS low power operation: 36 mW (typical) operating 12 W (typical) CMOS standby * TTL compatible interface levels * Single power supply: 2.5V--3.6V VDD (IS62WV10248BLL) * Fully static operation: no clock or refresh required * Three state outputs * Industrial temperature available * Lead-free available ISSI MARCH 2006 (R) DESCRIPTION The ISSI IS62WV10248BLL is a high-speed, 8M bit static RAMs organized as 1M words by 8 bits. It is fabricated using ISSI's high-performance CMOS technology. This highly reliable process coupled with innovative circuit design techniques, yields high-performance and low power consumption devices. When CS1 is HIGH (deselected) or when CS2 is LOW (deselected), the device assumes a standby mode at which the power dissipation can be reduced down with CMOS input levels. Easy memory expansion is provided by using Chip Enable and Output Enable inputs. The active LOW Write Enable (WE) controls both writing and reading of the memory. The IS62WV10248BLL is packaged in the JEDEC standard 48-pin mini BGA (7.2mm x 8.7mm).

Test conditions assume signal transition times of 5 ns or less, timing reference levels of 1.5V, input pulse levels of 0.4V to VDD0.3V and output loading specified in Figure 1. 2. The internal write time is defined by the overlap of CS1 LOW, CS2 HIGH and WE LOW. All signals must be in valid states to initiate a Write, but any one can go inactive to terminate the Write. The Data Input Setup and Hold timing are referenced to the rising or falling edge of the signal that terminates the write. 3. Tested with the load in Figure 2.
