ACE93C46.56.66

Three-wire Serial EEPROM

Description

The ACE93C46/56/66 provides 1024/2048/4096 bits of serial electrically erasable programmable read only memory

(EEPROM) organized as 64/128/256 words of 16 bits each, when the ORG pin is connected to VCC and 128/256/512

words of 8 bits each when it is tied to ground. The ACE93C46/56/66 is available in space-saving 8-lead PDIP, 8-lead

TSSOP and 8-lead JEDEC SOIC packages. The ACE93C46/56/66 is enabled through the Chip Select pin (CS), and

accessed via a 3-wire serial interface consisting of Data Input (DI), Data Output (DO), and Shift Clock (SK). Upon

receiving a Read instructionat DI, the address is decoded and the data is clocked out seriallyon the data output pin DO.

The WRITE cycle is completely self-timed and no separate erase cycle is required before write. The Write cycle is only

enabled when it is in the Erase/Write Enable state. When CS is brought “high” following the initiation of a write cycle, the

DO pin outputsthe Ready/Busystatus.

Features

 Low-voltage operation – 1.8 (VCC=1.8V to 5.5V)

 Three-wire serial Interface

 2MHz clock rate(5V) compatibility

 Self-timed write cycle (5 ms max)

 High-reliability – Endurance: 1 Million write cycles

Data retention: 100 Years
