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.
