GENERAL DESCRIPTION

The MX29LV320MT/B is a 32-mega bit Flash memory organized as 4M bytes of 8 bits or 2M bytes of 16 bits. MXICs Flash memories offer the most cost-effective and reliable read/write non-volatile random access memory. The MX29LV320MT/B is packaged in 44-pin SOP, 48-pin TSOP and 48-ball CSP. It is designed to be reprogrammed and erased in system or in standard EPROM programmers.

FEATURES

GENERAL FEATURES
