Description

Page Latches

The Microchip Technology Inc. 24LCS22A is a 256 x 8-bit

dual-mode Electrically Erasable PROM (EEPROM). This

device is designed for use in applications requiring

storage and serial transmission of configuration and

control information. Two modes of operation have been

implemented: Transmit-only mode (1K-bit) and

Bidirectional mode (2K-bit). 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 24LCS22A is

available in standard 8-pin DIP and SOIC packages. The

24LCS22A features a flexible Write-Protect pin which is

enabled by writing to address 7Fh (usually the checksum

in VESA^®applications.
