29F040B
Description
The Am29F040B is a 4 Mbit, 5.0 volt-only Flash memory organized as 524,288 Kbytes of 8 bits each. The 512 Kbytes of data are divided into eight sectors of 64 Kbytes each for flexible erase capability.
Key Features
- 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
- 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 supply for both read and write functions
- Internally generated and regulated voltages are provided for the program and erase operations
- The device is entirely mand set compatible with the JEDEC single-power-supply Flash standard
- mands are written to the mand register using standard microprocessor write timings
- Register contents serve as input to an internal state-machine that controls the erase and programming circuitry
- Write cycles also internally latch addresses and data needed for the programming and erase operations
- Reading data out of the device is similar to reading from other Flash or EPROM devices
