DESCRIPTION

16K bit

Cell Matrix

Decoder

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.
