DESCRIPTION

The Microchip Technology Inc. 24LCS21 is

128 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

implemented: Transmit Only Mode and bi-directional

Mode. Upon power-up, the device will be in the Transmit

Only Mode, sending a serial bit stream of the entire

memory array contents, clocked by the VCLK pin. A

valid high to low transition on the SCL pin will cause the

device to enter the bi-directional Mode, with byte select-

able read/write capability of the memory array in stan-

The 24LCS21 also enables the user to write-protect the

entire memory contents using its write-protect pin. The

24LCS21 is available in a standard 8-pin PDIP and

SOIC package in both commercial and industrial

temperature ranges.
