  Current:
  - 28mA read current (word mode)
  - 20 mA typical active read current (byte mode)
  - 30 mA typical program/erase current
  - 1 mA typical CMOS standby  
  Flexible sector architecture
- 16 Kbyte/ 8 KbyteX2/ 32 Kbyte/ 64 KbyteX15 sectors
- 8 Kword/ 4 KwordX2/ 16 Kword/ 32 KwordX15 sectors
- 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 
  Top or bottom boot block configurations available 
  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 
  Hardware reset pin (RESET)
- Hardware method to reset the device to reading array
data 
  Package options
- 44-pin SOP or 48-pin TSOP (I)

Description

The A29800 is a 5.0 volt only Flash memory organized as 1048,576 bytes of 8 bits or 524,288 words of 16 bits each. The A29800 offers the RESET function. The 1024 Kbytes of data are further divided into nineteen sectors for flexible sector erase capability. The 8 bits of data appear on I/O0 - I/O7 while the addresses are input on A1 to A18; the 16 bits of data appear on I/O0~I/O15. The A29800 is offered in 44-pin SOP and 48-Pin TSOP 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 A29800 can also be programmed in standard EPROM programmers.
