DESCRIPTION
The Microchip Technology Inc. 24LC32A is a 4K x 8
(32K bit) Serial Electrically Erasable PROM capable of
operation across a broad voltage range (2.5V to 6.0V).
It has been developed for advanced, low power appli-
cations such as personal communications or data
acquisition. The 24LC32A also has a page-write capa-
bility of up to 32 bytes of data. The 24LC32A is capable
of both random and sequential reads up to the 32K
boundary. Functional address lines allow up to eight
24LC32A devices on the same bus, for up to 256K bits
address space. Advanced CMOS technology and
broad voltage range make this device ideal for low-
power/low-voltage, nonvolatile code and data applica-
tions. The 24LC32A is available in the standard 8-pin
plastic DIP and both 150 mil and 200 mil SOIC packag-
ing.
