EC24C512A
512K bitsTwo-wire Serial EEPROM
General Description
Features
The EC24C512A provides 524,288 bits of serial
electrically erasable and programmable read-only
memory (EEPROM), organized as 65,536 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 EC24C512A is available in space-
saving 8-lead PDIP, 8-lead SOP, and 8-lead
TSSOP packages and is accessed via a two-wire
serial interface. In addition, the EC24C512A is
available in 1.7V (1.7V to 5.5V) version.
