Package Types

Description:

The Microchip Technology Inc. 34VL02 is a 2 Kbit

Electrically Erasable PROM capable of operation

across a broad voltage range (1.5V to 3.6V). 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 1.5V, with standby and active cur-

rents of only 100 nA and 1 mA, respectively. The

34VL02 also has a page write capability for up to 16

bytes of data. The 34VL02 is available in the standard

8-pin PDIP, surface mount SOIC, TSSOP, MSOP and

TDFN packages. The 34VL02 is also available in the

6-lead, SOT-23 package.
