DESCRIPTION  
HV GENERATOR  
The Microchip Technology Inc. 24LC04B/08B is a 4  
Kbit or 8 Kbit Electrically Erasable PROM (EEPROM).  
The device is organized as two or four blocks of 256 x  
8-bit memory with a 2-wire serial interface. Low voltage  
design permits operation down to 2.5 volts with typical  
standby and active currents of only 5 µA and 1 mA  
respectively. The 24LC04B/08B also has a page-write  
capability for up to 16 bytes of data. The 24LC04B/08B  
is available in the standard 8-pin DIP, 8-lead surface  
mount SOIC, MSOP and TSSOP packages.
