A29010

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
- 32 KbyteX4 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
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)

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.
