DESCRIPTION
The Microchip Technology Inc. 59C11 is a 1K bit Elec-
trically Erasable PROM. The device is configured as
128 x 8 or 64 x 16, selectable externally by means of
the control pin ORG. Advanced CMOS technology
makes this device ideal for low power nonvolatile mem-
ory applications. The 59C11 is available in the standard
8-pin DIP and a surface mount SOIC package.
