General Description
   The A29001B is a 5.0 volt-only Flash memory organized as 131,072 bytes of 8 bits each. The A29001B offers the RESET function, but it is not available on A290011B. The 128 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 A16. The A29001B is offered in 32-pin PLCC, PDIP and TSOP packages. This device is designed to be programmed insystem 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 A29001B can also be programmed in standard EPROM programmers.

FEATUREs
◾ 5.0V ± 10% for read and write operations
◾ Access time:
   - 55ns (max.)
◾ Current:
   - 20mA typical active read current
   - 30mA typical program/erase current
   - 6μA typical CMOS standby
◾ Flexible sector architecture
   - 8 Kbyte/ 4 KbyteX2/ 16 Kbyte/ 32 KbyteX3 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
◾ Minimum 100,000 program/erase cycles per sector
◾ 20-year data retention at 125ºC
   - 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 (not available on A290011B)
◾ Industrial operating temperature range: -40°C to +85°C
   for – U
◾ Package options
   - 32-pin P-DIP, PLCC or TSOP
   - All Pb-free (Lead-free) products are RoHS2.0 compliant
