256K X 8 Bit CMOS 5.0 Volt-only, Boot Sector Flash Memory

The A29002 is a 5.0 volt-only Flash memory organized as 262,144 bytes of 8 bits each. The A29002 offers the RESET function, but it is not available on A290021. The 256 Kbytes of data are further divided into seven sectors for flexible sector erase capability. The 8 bits of data appear on I/O0 - I/O7 while the addresses are input on A0 to A17. The A29002 is offered in 32-pin PLCC, TSOP, and PDIP packages. This device is designed to be programmed in-system with the standard system 5.0 volt VCC supply. Additional 12.0 volt VPP is not required for in-system write or erase operations. However, the A29002 CAN also be programmed in standard EPROM programmers. The A29002 has the first toggle bit, I/O6, which indicates whether an Embedded Program or Erase is in progress, or it is in the Erase Suspend. Besides the I/O6 toggle bit, the A29002 has a second toggle bit, I/O2, to indicate whether the addressed sector is being selected for erase. The A29002 also offers the ability to program in the Erase Suspend mode. The standard A29002 offers access times of 55, 70, 90, 120, and 150 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. By AMIC Technology Corporation
