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

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.
