Description:

The Microchip Technology Inc. 24LC22A is a 256 x 8-

bit dual-mode Electrically Erasable PROM. This device

is designed for use in applications requiring storage

and serial transmission of configuration and control

information. Two modes of operation have been imple-

mented: Transmit-Only mode (1 Kbit) and Bidirectional

mode (2 Kbit). Upon power-up, the device will be in the

Transmit-Only mode, sending a serial bit stream of the

memory array from 00h to 7Fh, clocked by the VCLK

pin. A valid high-to-low transition on the SCL pin will

cause the device to enter the Transition mode, and look

for a valid control byte on the I²C bus. If it detects a

valid control byte from the master, it will switch into

Bidirectional mode, with byte selectable read/write

capability of the entire 2K memory array using SCL. If

no control byte is received, the device will revert to the

Transmit-Only mode after it receives 128 consecutive

VCLK pulses while the SCL pin is idle. The 24LC22A is

available in standard 8-pin PDIP and SOIC packages.
