AX24C128A/256A
128K/256K-bit 2- WIRE SERIAL CMOS EEPROM
General Description
Features
The AX24C128A/AX24C256A provides
131,072/262,144 bits of serial electrically erasable
and programmable read-only memory (EEPROM)
organized as16,384/32,768 words of 8 bits each.
The device is optimized for use in many industrial
and commercial applications where low-power and
low-voltage operation are essential. The
AX24C128A/AX24C256A is available in space-
saving SOP-8 and TSSOP-8 packages and is
accessed via a two-wire serial interface. In addition,
the AX24C128A/AX24C256A is available in 1.7V
(1.7V to 5.5V) version.
Wide Voltage Operation
- VCC = 1.7V to 5.5V
Operating Ambient Temperature:
-40°C to +85°C
Internally Organized:
- AX24C128A, 16,384 X 8 (128K bits)
- AX24C256A, 32,768 X 8 (256K bits)
