General Description

The A29L008A is an 8Mbit, 3.0 volt-only Flash memory organized as 1,048,576 bytes. The data appear on I/O0 - I/O7. The A29L008A is offered in 40-pin TSOP package. This device is designed to be programmed in-system with the standard system 3.0 volt VCC supply. Additional 12.0 volt VPP is not required for in-system write or erase operations. However, the A29L008A can also be programmed in standard EPROM programmers.

Features

■ Single power supply operation

- Full voltage range: 2.7 to 3.6 volt read and write

operations for battery-powered applications

■ Access times:

- 70/90 (max.)

■ Current:

- 9 mA typical active read current

- 20 mA typical program/erase current

- 200 nA typical CMOS standby

- 200 nA Automatic Sleep Mode current

■ Flexible sector architecture

- 16 Kbyte/ 8 KbyteX2/ 32 Kbyte/ 64 KbyteX15 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. Temporary Sector Unprotect feature allows code

changes in previously locked sectors

■ Extended operating temperature range: -40°C ~ +85°C for -U series

■ Unlock Bypass Program Command

- Reduces overall programming time when issuing

multiple program command sequence

■ Top or bottom boot block configurations available

■ Embedded 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 data 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

■ Ready / BUSY pin (RY / BY )

- Provides a hardware 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

- 40-pin TSOP (I)
