GENERAL DESCRIPTION

The MX29LV002C T/B is a 2-mega bit Flash memory organized as 256K bytes of 8 bits. MXICs Flash memories offer the most cost-effective and reliable read/write non-volatile random access memory. The MX29LV002C T/B is packaged in 32-pin TSOP and 32-pin PLCC. 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

• 262,411 x 8

• Single power supply operation

- 3.0V only operation for read, erase and program operation

• Fast access time: 70/90ns

• Low power consumption

- 20mA maximum active current

- 0.2uA typical standby current

• Command register architecture

- Byte Programming (9us typical)

- Sector Erase (Sector structure 16K-Byte x 1, 8K-Byte x 2, 32K-Byte x1, and 64K-Byte x3)

• 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.

• 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

- Temporary sector unprotect allows code changes in previously locked sectors
