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 technology
makes these devices ideal for low power, nonvolatile
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 packag-
ing such as the 8-lead MSOP, 8-lead TSSOP, 6-lead
SOT-23, and 8-lead DFN (2x3). These packages are all
available in a Pb-free (Matte Tin) finish. Packaging with
the Sn/Pb finish is also available as a custom device.
