The A29512 is a 5.0 volt-only Flash memory organized as 65,535 bytes of 8 bits each. The 64 Kbytes of data are further divided into four sectors for flexible sector erase capability. The 8 bits of data appear on l/00 - l/07 while the addresses are input on AO to A15. The A29512 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 A29512 can also be programmed in standard EPROM programmers. The A29512 has the first toggle bit, l/06, which indicates whether an Embedded Program or Erase is in progress, or it is in the Erase Suspend. Besides the l/06 toggle bit, the A29512 has a second toggle bit, l/02, to indicate whether the addressed sector is being selected for erase. The A29512 also offers the ability to program in the Erase Suspend mode. The standard A29512 0ffers access times of 55, 70 and 90 ns allowing high-speed microprocessors to operate without wait states. To eliminate bus contention the device has
