Description:  
Page Latches  
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.
