Description:  
HV Generator  
The Microchip Technology Inc. 24LCS21A is a  
128 x 8-bit dual-mode Electrically Erasable PROM.  
This device is designed for use in applications  
requiring storage and serial transmission of configura-  
tion 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 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 memory array using SCL.  
If no control byte is received, the device will revert to  
the Transmit-Only mode after it receives 128 consec-  
utive VCLK pulses while the SCL pin is idle. The  
24LCS21A also enables the user to write-protect the  
entire memory array using its write-protect pin. The  
24LCS21A is available in a standard 8-pin PDIP and  
SOIC package in both commercial and industrial  
temperature ranges.
