Description
AI
The Microchip Technology Inc. 34VL02/34AA02/
34LC02 (34XX02\*) is a 2 Kbit Electrically Erasable
PROM capable of operation across a broad voltage
range (1.5V to 5.5V). This device has two software
write-protect features for the lower half of the array, as
well as an external pin that can be used to write-protect
the entire array. The device is organized as one block of
256 x 8-bit memory with a 2-wire serial interface. Low voltage design permits operation down to 1.5V, with
standby and active currents of only 100 nA and 1 mA,
respectively. The 34XX02 also has a page write capability
for up to 16 bytes of data. The 34XX02 is available
in the standard 8-pin PDIP, surface mount SOIC,
TSSOP, MSOP and DFN packages.
