General Description
A29040B General Description
The A29040B is a 5.0 volt-only Flash memory organized as 524,288 bytes of 8 bits each. The 512 Kbytes of data are further divided into eight sectors of 64 Kbytes each for flexible sector erase capability. The 8 bits of data appear on I/O0 - I/O7 while the addresses are input on A0 to A18. The A29040B is offered in 32-pin PLCC, TSOP, and PDIP packages. This device is designed to be programmed in- system with the standard system 5.0volt VCC supply. Additional 12.0 volt VPP is not required for in-system write or erase operations. However, the A29040B can also be programmed in standard EPROM programmers.
The A29040B has a second toggle bit, I/O2, to indicate whether the addressed sector is being selected for erase, and also offers the ability to program in the Erase Suspend mode. The standard A29040B offers access times of 55, 70 and 90 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 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.
