Description:

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

(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 Trans-

mit-Only mode after it receives 128 consecutive VCLK

pulses while the SCL pin is idle. The 24LCS22A is avail-

able in standard 8-pin PDIP 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.
