The Microchip Technology Inc. 24LCS21 is a 128 x 8-bitdual-mode Electrically Erasable PROM. This device isdesigned for use in applicaTIons requiring storage andserial transmission of configuraTIon and control informaTIon.Two modes of operaTIon have been implemented:Transmit-only mode and Bidirectional mode. Uponpower-up, the device will be in the Transmit-only mode,sending a serial bit stream of the entire memory arraycontents, clocked by the VCLK pin. A valid high-to-lowtransition on the SCL pin will cause the device to enterthe Bidirectional mode, with byte selectable read/writecapability of the memory array in standard I2C protocol.The 24LCS21 also enables the user to write-protect theentire memory contents using its write-protect pin. The24LCS21 is available in a standard 8-pin PDIP andSOIC package in both commercial and industrialtemperature ranges.
