- Any combination 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
Embedded Erase Algorithms
  - Embedded Erase algorithm will automatically erase  the entire chip or any combination of designated  sectors and verify the erased sectors 
  - Embedded Program algorithm automatically writes  and verifies bytes at specified addresses
Typical 100,000 program/erase cycles per sector 
20-year data retention at 125°C
  - Reliable operation for the life of the system
Compatible with JEDEC-standards
  - Pinout and software compatible with single-power-
supply Flash memory standard
- Superior inadvertent write protection
Data  Polling and toggle bits
- Provides a software method of detecting completion  of program or erase operations
Erase Suspend/Erase Resume
-  Suspends a sector erase operation to read data  from, or program data to, a non-erasing sector, then  resumes the erase operation  Package options
- 32-pin P-DIP, PLCC, or TSOP(Forward type)

Description

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 I/O0 - I/O7 while the addresses  are input on A0  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, 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  A29512 has a second toggle bit, I/O2, 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 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.
