A29010B Datasheet | AMIC

Features - 5.0V ± 10% for read and write operations - Access times: - 55ns (max.) - Current: - 20m A typical active read current - 30m A typical program/erase current - 6μA typical CMOS standby - Flexible sector architecture - 32 Kbyte X4 sectors - Any bination of sectors can be erased - Supports full chip erase - Sector protection: A hardware method of protecting sectors to prevent any inadvertent program or erase operations within that sector - Extended operating temperature range: -40°C~+85°C for - U series - Embedded Erase Algorithms - Embedded Erase algorithm will automatically erase the entire chip or any bination of designated sectors and verify the erased sectors General Description The A29010B is a 5.0 volt-only Flash memory organized as 131,072 bytes of 8 bits each. The 128 Kbytes of data are further divided into four 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 A16. The A29010B 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 A29010B can also be programmed in standard EPROM programmers. The A29010B 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 A29010B has a second toggle bit, I/O2, to indicate whether the addressed sector is being selected for erase. The A29010B also offers the ability to program in the Erase Suspend mode. The standard A29010B offers access times of 55ns 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...
