Am29LV320MT

The Am29LV320M/TB is a 32 Mbit, 3.0 volt single power supply flash memory device organized as 2,097,152 words or 4,194,304 bytes. The device has an 8-bit/16-bit bus and can be programmed either in the host system or in standard EPROM programmers.

An access time of 90, 100, 110, or 120 ns is available. Note that each access time has a specific operating voltage range (VCC) and an I/O voltage range (VIO), as specified in the Product Selector Guide and the Ordering Information sections. The device is offered in a 48-pin TSOP, 48-ball Fine-pitch BGA or 64-ball Fortified BGA package. Each device has separate chip enable (CE#), write enable (WE#) and output enable (OE#) controls.

Each device requires only a single 3.0 volt power supply for both read and write functions. In addition to a VCC input, a high-voltage accelerated program (ACC) function provides shorter programming times through increased current on the WP#/ACC input. This feature is intended to facilitate factory throughput during system production, but may also be used in the field if desired.

The device is entirely command set compatible with the JEDEC single-power-supply Flash standard. Commands are written to the device using standard microprocessor write timing. Write cycles also internally latch addresses and data needed for the programming and erase operations.

The sector erase architecture allows memory sectors to be erased and reprogrammed without affecting the data contents of other sectors. The device is fully erased when shipped from the factory.
