| ICs for TV-SETS INA2586 1024 x 8-Bit n-MOS EEPROM with I2C-Bus Interface The INA2586 is a 8-Kbit (1024 x 8-bit) n-MOS floating gate electrically erasable programmable read only memory (EEPROM). 2 2 IC works in systems with serial I C-bus. Up to two INA2586 devices may be connected to the I C-bus.The programming of the array is implemented by electron's tunneling. The programming voltage is generated on-chip, using a voltage multiplier. Device is functionally identical to the SDA2586, Siemens. IC are made in 8-pin DIP and 8-pin SOP. FEATURES Non-volatile storage of information during 10 years Single supply (Ucc=4,75 B - 5,25 B) On-chip voltage multiplier On-chip generator of bulk biasing 2 Serial input/output I C-bus 10 000 ERASE/WRITE cycles per byte; Internal reprogramming (no external components) Duration of the ERASE/WRITE cycle is 15 ms 0 Temperature range: 0 / +70 C ELECTRICAL CHARACTERISTICS Parameter Supply current, mA Output low voltage (SDA), V High leakage current: -on output (SDA), A -on inputs SCL, SDA, A -on inputs CS, TP1, TP2,A Input capacitance, pF Clock input frequency, kHz Reprogramming cycle time, ms Erase of die cycle time, ms The number of E/W cycles on 1 byte Input high voltage: -inputs SDA, SCL, V -inputs CS, TP1, TP2, V Input low voltage: -inputs SDA, SCL, V -inputs CS, TP1, TP2, V Conditions UCC=5.25 B IOL=3 mA UCC=4.75B UOH=5,25 B UIH=5,25 B UIH=5,25 B U I= 0 B Erase and Write UTP2= 5,0 B Symbol ICC0 UOL ILOH ILIH ILIH CI fSCL tPROG tER UIH UIL Min. 0 10,0 10 000 3,0 4,5 Max 20,0 0,4 10,0 10,0 100,0 10,0 100 20,0 20,0 UCC UCC 1,5 0,2 PIN ASSIGNMENT PIN DESCRIPTION SYMBOL Uss CS TP1 TP2 SDA SCL TP3 Ucc PIN 1 2 3 4 5 6 7 8 DESCRIPTION GND Chip selection Testing pin Testing pin (0V - normal mode, 5V - chip erasing) Informational line, input/output Clock input Testing pin, not connected Supply Voltage Uss CS 1 2 3 4 8 7 6 5 Ucc TP3 SCL SDA TP1 TP2 1 INTEGRAL |
