Description:

The Microchip Technology Inc. 24LC21 is a 128 x 8 bit

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 Bidirectional 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 Bidirectional mode, with byte selectable read/write

capability of the memory array. The 24LC21 is available

in a standard 8-pin PDIP and SOIC package, in both

commercial and industrial temperature ranges.
