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.

Features

● 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-powersupply 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)
   - All Pb-free (Lead-free) products are RoHS2.0 compliant
