The MX29F8100 is a 8-mega bit Flash memory organized as either 512K wordx16 or 1M bytex8. The MX29F8100 includes 8-128KB(131,072) blocks or 8-64KW(65,536) blocks. MXIC's Flash memories offer the most costeffective and reliable read/write non-volatile random access memory. The MX29F8100 is packaged in 48-pin TSOP or 44-pin SOP. For 48-pin TSOP, CE2 and RY/BY are extra pins compared with 44-pin SOP package. This is to optimize the products (such as solid-state disk drives or flash memory cards) control pin budget. PWD is available in 48 -pin TSOP for low power environment. All the above three pins(CE2,RY/BY and PWD) plus one extra VCC pin are not provided in 44-pin SOP. It is designed to be reprogrammed and erased in-system or in-standard EPROM programmers.
