GENERAL DESCRIPTION

The MX29F004T/B 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 MX29F004T/B is

packaged in 32-pin PLCC, TSOP, PDIP. It is designed to be reprogrammed and erased in system or in standard EPROM programmers.
