Description
The Microchip Technology Inc. 34AA04 is a 4 Kbit
Electrically Erasable PROM which utilizes the I
2
C serial
interface and is capable of operation across a broad
voltage range (1.7V to 3.6V). This device is JEDEC
JC42.4 (EE1004-v) Serial Presence Detect (SPD)
compliant and includes reversible software write
protection for each of four independent 128 x 8-bit
blocks. The device features a page write capability of
up to 16 bytes of data. Address pins allow up to eight
devices on the same bus.
The 34AA04 is available in the 8-lead PDIP, SOIC,
TSSOP, TDFN, and UDFN packages.
