A93C56
THREE-WIRE SERIAL EEPROM
2K (256 X 8 OR 128 X 16)
DESCRIPTION
FEATURES
The A93C56 provides 2048 bits of serial electrically Three-wire Serial Interface
erasable programmable read only memory
(EEPROM) organized as 128 words of 16 bits each,
when the ORG pin is connected to VCC and 256
words of 8 bits each when it is tied to ground.
The A93C56 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 instruction
at DI, the address is decoded and the data is clocked
VCC = 1.8V to 5.5V
Sequential Read Operation
2 MHz Clock Rate (5V) Compatibility
Self-timed Write Cycle (5 ms max)
1 Million Write Cycles guaranteed
Data Retention > 100 Years
Available in SOP8 and TSSOP8 Package 
 
ORDERING INFORMATION
out serially on 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
