GENERAL DESCRIPTION

The MX29LV081B is a 8-mega bit Flash memory organized as 1M bytes of 8 bits. MXICs Flash memories offer the most cost-effective and reliable read/write nonvolatile random access memory. The MX29LV081B is packaged in 40-pin TSOP. It is designed to be reprogrammed and erased in system or in standard EPROM programmers.

FEATURES

• Status Reply

- Data polling & Toggle bit for detection of program and erase operation completion.

• Ready/Busy pin (RY/BY)

- Provides a hardware method of detecting program or erase operation completion.

• Sector protection

- Hardware method to disable any combination of sectors from program or erase operations

- Any combination of sectors can be erased with erase suspend/resume function.

- Temporary sector unprotect allows code changes in previously locked sectors.

• 100,000 minimum erase/program cycles

• Latch-up protected to 100mA from -1V to VCC+1

• Package type:

- 40-pin TSOP

- Sector Erase (Sector structure 64K-Byte x16)

• Auto Erase (chip & sector) and Auto Program

- Automatically erase any combination of sectors with Erase Suspend capability.

- Automatically program and verify data at specified address

• Erase suspend/Erase Resume

- Suspends sector erase operation to read data from, or program data to, any sector that is not being erased, then resumes the erase.
