آی سی 93C46

آی سی 93C46

EEPROM ، حروف اختصاری عبارت Electrically ErasableProgrammable ROM است و همان طور که از اسمش بر می آید قابل پاک کردن به وسیله سیگنال های الکتریکی است . تراشه EEPROM تعدادی پایه دارد که هر گاه سیگنال الکتریکی وارد این پایه ها شود محتویات آن قابل برنامه ریزی می شود .

1K/2K/4K 1.8V Microwire® Serial EEPROM

The Microchip Technology Inc. 93AA46/56/66 are 1K, 2K and 4K low voltage serial Electrically Erasable PROMs. The device memory is configured as x8 or x16 bits depending on the ORG pin setup. Advanced CMOS technology makes these devices ideal for low power non-volatile memory applications. The 93AA Series is available in standard 8-pin DIP and surface mount SOIC packages. The rotated pin-out 93AA46X/56X/66X are offered in the “SN” package only.

Features:

• Single supply with programming operation down to 1.8V
• Low power CMOS technology :     

- 70 µA typical active READ current at 1.8V            

- 2 µA typical standby current at 1.8V

•  ORG pin selectable memory configuration :    

- 128 x 8- or 64 x 16-bit organization (93AA46)    

 - 256 x 8- or 128 x 16-bit organization (93AA56)
