Description:
Microchip Technology Inc. supports the 3-wire
Microwire bus with low-voltage serial Electrically
Erasable PROMs (EEPROM) that range in density
from 1 Kbits up to 16 Kbits. Each density is available
with and without the ORG functionality, and selected
by the part number ordered. Advanced CMOS technol-
ogy makes these devices ideal for low-power, nonvol-
atile memory applications. The entire series of
Microwire devices are available in the standard 8-lead
PDIP and SOIC packages, as well as the more
advanced packaging such as the 8-lead MSOP, 8-lead
TSSOP, 6-lead SOT-23, and 8-lead DFN (2x3). All
packages are Pb-free.
