Description
The Atmel® AT24C32D provides 32,768 bits of Serial Electrically Erasable and
Programmable Read-Only Memory (EEPROM) organized as 4,096 words of 8 bits
each. The device’s cascading feature allows up to eight devices to share a
common 2-wire bus. The device is optimized for use in many industrial and
commercial applications where low-power and low-voltage operation are
essential. The devices are available in space-saving 8-lead JEDEC SOIC, 8-lead
TSSOP, 8-pad UDFN, 8-pad XDFN, 5-lead SOT23, 5-ball WLCSP, and 8-ball
VFBGA packages. In addition, this device operates from 1.7V to 5.5V.
