S-2812A

The S-2812A is designed as low power 2Kx8-bit parallel E2PROM. It features wide operating voltage range. Since provided with 32-byte page write function, it can perform fast programming operation.

S-2812A has twelve features. (1)Access time 150ns. (2)Low power consumption 30mA max for operating and 1uA max for standby. (3)Operating voltage range would be from 1.8V to 5.5V for read and 2.7V to 5.5V for write. (4)Write inhibition 2.1V typ. (5)Data polling. (6)With ready pin. (7)Page write for 32 bytes. (8)Rewritings 10^5 times. (9)Data retention 10 years. (10)Program noise immunity. (11)Package 28-pin DIP/SOP/TSOP. (12)Supply in bare chip is also available. Those are all the main fetaures.

Some absolute maximum ratings of S-2812A have been concluded into several points as follow. (1)Its power supply voltage would be from -0.3V to 7V. (2)Its input voltage would be from -0.3V to Vcc+0.3V. (3)Its output voltage would be from -0.3V to Vcc. (4)Its storage temperature range under bias would be from -50°C to 95°C. (5)Its storage temperature range would be from -65°C to 150°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of S-2812A at Vcc=5.0V+/-10% are concluded as follow. (1)Its current consumption READ would be max 30mA. (2)Its current consumption program would be max 30mA. (3)Its standby current consumption would be max 1.0uA for /CE>=Vih. (4)Its input leakage current would be typ 0.1uA and max 1.0uA. (5)Its output leakage current would be typ 0.1uA and max 1.0uA. (6)Its low level output voltage would be max 0.4V. (7)Its high level output voltage would be min 2.4V. And so on. At present we have not got so much information about this IC and we would try hard to get more information about it.
