Description
The AT29C432 is a CMOS memory specifically designed for applications requiring
both a high density nonvolatile program memory and a smaller nonvolatile data mem-
ory. The AT29C432 provides this in the form of a 4 megabit Flash array integrated
with a 256K bit full featured E
2
PROM array on the same device. A unique feature of
this device is its concurrent read while writing capability. This provides the host sys-
tem read access to the Flash program memory during the write cycle time of the
E
2
PROM.
The two memory arrays share all I/O lines, Address lines and OE and WE inputs.
Each memory array has its own Chip Enable input: CEF for the Flash array and CEE
for the E
2
PROM array.
Additionally, Software Data Protection has been independently implemented for both
arrays and is always enabled. The AT29C432 has a pinout similar to the AT29C040A
Flash memory. A system designer using a Flash memory for program storage and
another smaller, non volatile memory for data storage can easily replace both memo-
ries with the AT29C432.
