Product Summary
The am29lv081b-70ei is an 8 Mbit, 3.0 volt-only Flash memory organized as 1,048,576 bytes. The device is offered in a 40-pin TSOP package. The byte-wide (x8) data appears on DQ7–DQ0. This device requires only a single, 3.0 volt VCC supply to perform read, program, and erase operations. A standard EPROM programmer can also be used to program and erase the device. The am29lv081b-70ei is manufactured using AMD’s 0.32 μm process technology, and offers all the features and benefits of the device, which was manufactured using 0.5 μm process technology. In addition, the am29lv081b-70ei features unlock bypass programming and in-system sector protection/unprotection. The standard device offers access times of 70, 90, and 120 ns, allowing high speed microprocessors to operate without wait states. To eliminate bus contention the device has separate chip enable (CE#), write enable (WE#) and output enable (OE#) controls. The am29lv081b-70ei requires only a single 3.0 volt power supply for both read and write functions. Internally generated and regulated voltages are provided for the program and erase operations.
