Supply original MX29GL256FHT2I-90Q, Memory, by Macronix

GENERAL
The MX29F002T/B is a 2-mega bit Flash memory organized as 256K bytes of 8 bits only. MXICs Flash memories offer the most cost-effective and reliable read/write nonvolatile random access memory.
The MX29F002T/B is packaged in 32-pin PDIP,PLCC and 32-pin TSOP(I). It is designed to be reprogrammed and erased in-system or in standard EPROM programmers.
FEATURES
