Description  
AT29C432  
ConcurrentFlash  
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  
2
with a 256K bit full featured E 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 PROM.  
2
Preliminary  
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  
2
for the E 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.
