DESCRIPTION
The Microchip Technology Inc. 28C16A is a CMOS 16K
non-volatile electrically Erasable PROM. The 28C16A
is accessed like a static RAM for the read or write
cycles without the need of external components. Dur-
ing a “byte write”, the address and data are latched
internally, freeing the microprocessor address and data
bus for other operations. Following the initiation of
write cycle, the device will go to a busy state and auto-
matically clear and write the latched data using an
internal control timer. To determine when a write cycle
is complete, the 28C16A uses Data polling. Data poll-
ing allows the user to read the location last written to
when the write operation is complete. CMOS design
and processing enables this part to be used in systems
where reduced power consumption and reliability are
required. A complete family of packages is offered to
provide the utmost flexibility in applications.
