... 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 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 ...

... The state of adresses and A15 - A18 spec- ify the individual byte address within a sector and the state of addresses A4 - A14 define the sector to be written. The AT29C432 employs the JEDEC standard software data protection feature; therefore, each programming se- quence must be preceded by the three byte program com- mand sequence ...

... This sequence should then immedi- ately be followed by one to sixteen bytes of data. After the last byte has been written, the AT29C432 will automat- ically time itself to completion of the internal write cycle. The write cycle is initiated by both WE and CEE going low; ...

... With other programmable non- volatile memories internal high voltage operations prevent the reading of data while a write operation is in process. However, the AT29C432 is partitioned in a manner to al- low read operations from the Flash memory array during a 2 write operation within the E PROM memory array ...
