Am29F040B-70ECB General Description
The Am29F040B is a 4 Mbit, 5.0 volt-only Flash mem-ory organized as 524,288 Kbytes of 8 bits each. The512 Kbytes of data are divided into eight sectors of 64Kbytes each for flexible erase capability. The 8 bits of data appear on DQ0DQ7. The Am29F040B is offered in 32-pin PLCC, TSOP, and PDIP packages. This device is designed to be programmed in-system with thestandard system 5.0 volt VCC supply. A 12.0 volt VPP isnot required for write or erase operations. The device can also be programmed in standard EPROM pro-grammers.
This device is manufactured using AMD's 0.35 µmprocess technology, and offers all the features and ben-efits of the Am29F040, which was manufactured using 0.5 µm process technology. In addtion, the Am29F040B has a second toggle bit, DQ2, and also offers the ability to program in the Erase Suspend mode.The standard Am29F040B offers access times of 55,70, 90, 120, and 150 ns, allowing high-speed micropro-cessors 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 device requires only a single 5.0 volt power sup-ply for both read and write functions. Internally gener-ated and regulated voltages are provided for the program and erase operations.
