DESCRIPTION
The Microchip Technology Inc. 28C64A is a CMOS 64K non-
volatile electrically Erasable PROM. The 28C64A is
accessed like a static RAM for the read or write cycles without
the need of external components. During a “byte write”, the
address and data are latched internally, freeing the micropro-
cessor address and data bus for other operations. Following
the initiation of write cycle, the device will go to a busy state
and automatically clear and write the latched data using an
internal control timer. To determine when the write cycle is
complete, the user has a choice of monitoring the Ready/
Busy output or using Data polling. The Ready/Busy pin is an
open drain output, which allows easy configuration in wired-
or systems. Alternatively, Data polling allows the user to read
the location last written to when the write operation is com-
plete. CMOS design and processing enables this part to be
used in systems where reduced power consumption and reli-
ability are required. A complete family of packages is offered
to provide the utmost flexibility in applications
