A29800UM-70

1024K X 8 Bit / 512K X 16 Bit CMOS 5.0 Volt-only, Boot Sector Flash Memory

AMIC Technology 

A29800 Series

During erase, the device automatically times the erase pulse

widths and verifies proper erase margin.

The host system can detect whether a program or erase

operation is complete by reading the I/O7 ( Data Polling) and

I/O6 (toggle) status bits. After a program or erase cycle has

been completed, the device is ready to read array data or

accept another command.

The sector erase architecture allows memory sectors to be

erased and reprogrammed without affecting the data

contents of other sectors. The A29800 is fully erased when

shipped from the factory.

The hardware sector protection feature disables operations

for both program and erase in any combination of the

Pin Configurations

sectors of memory. This can be achieved via programming

equipment.

The Erase Suspend feature enables the user to put erase on

hold for any period of time to read data from, or program

data to, any other sector that is not selected for erasure.

True background erase can thus be achieved.

Power consumption is greatly reduced when the device is

placed in the standby mode.

The hardware RESET pin terminates any operation in

progress and resets the internal state machine to reading

array data.
