Description:
The Microchip Technology Inc. 34AA02/34LC02
(34XX02*) is a 2 Kbit Electrically Erasable PROM
capable of operation across a broad voltage range
(1.7V 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. 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 2-wire serial interface. 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. The 34XX02 is
available in the standard 8-pin PDIP, surface mount
SOIC, TSSOP, MSOP and TDFN packages. The
34XX02 is also available in the 6-lead, SOT-23
package.
*34XX02 is used in this document as a generic part number
for the 34AA02/34LC02 devices.
