General Description

The A29010 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 A29010 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 A29010 can also be programmed in standard EPROM programmers.

Features

● 5.0V ± 10 for read and write operations

● Access times:

- 55/70/90 (max.)

● Current:

- 20 mA typical active read current

- 30 mA typical program/erase current

- 1 mA typical CMOS standby

● Flexible sector architecture

- 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-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)
