GENERAL DESCRIPTION

The MX29LV040 is a 4-mega bit Flash memory organized as 512K bytes of 8 bits. MXICs Flash memories offer the most cost-effective and reliable read/write nonvolatile random access memory. The MX29LV040 is packaged in 32-pin PLCC and TSOP. It is designed to be reprogrammed and erased in system or in standard EPROM programmers.

FEATURES

• Extended single - supply voltage range 2.7V to 3.6V

• 524,288 x 8 only

• Single power supply operation

- 3.0V only operation for read, erase and program

operation

• Fast access time: 55R/70/90ns

• Low power consumption

- 20mA maximum active current

- 0.2uA typical standby current

• Command register architecture

- 8 equal sector of 64K-Byte each

- Byte Programming (9us typical)

- Sector Erase (Sector structure 64K-Byte x8)

• 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.

• Status Reply

- Data polling & Toggle bit for detection of program and

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.

- Tempoary sector unprotect allows code changes in

previously locked sectors.

• 100,000 minimum erase/program cycles
