Description

The Microchip Technology Inc. 34XX02(1) is a 2-Kbit

Electrically Erasable PROM (EEPROM). 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. This allows the

system designer to protect none, half or all of the array,

depending on the application. The device is organized

as one block of 256 x 8-bit memory with a two-wire

serial interface. Its low-voltage design permits

operation down to 1.7V, 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.
