Am29LV128ML

The Am29LV128MH/L is a 128 Mbit, 3.0 volt single power supply flash memory devices organized as 8,388,608 words or 16,777,216 bytes. The device has a 16-bit wide data bus that can also function as an 8-bit wide data bus by using the BYTE# input. The device 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 (V_CC) and an I/O voltage range (V_IO), as specified in the Product Selector Guide and the Ordering Information sections. The device is offered in a 56-pin TSOP, 64-ball Fortified BGA. 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 V_CC input, a high-voltage accelerated program (WP#/ACC) input provides shorter programming times through increased current. 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.

Device programming and erasure are initiated through command sequences. Once a program or erase operation has begun, the host system need only poll the DQ7 (Data# Polling) or DQ6 (toggle) status bits or monitor the Ready/Busy# (RY/BY#) output to determine whether the operation is complete. To facilitate programming, an Unlock Bypass mode reduces command sequence overhead by requiring only two write cycles to program data instead of four.

The VersatileI/O™ (VIO) control allows the host system to set the voltage levels that the device generates
