Hot-selling and scarce MX29F040CTI-70G 4M-BIT [512K x 8] CMOS SINGLE VOLTAGE 5V ONLY EQUAL SECTOR FLASH MEMORY TSOP32

Product Descriptions

The MX29F040C is a 4-mega bit Flash memory organized as 512K bytes of 8 bits. MXIC's Flash memories offer the most cost-effective and reliable read/write nonvolatile random access memory. The MX29F040C is packaged in 32-pin PLCC, TSOP, PDIP. It is designed to be reprogrammed and erased in system or in standard EPROM programmers.

The standard MX29F040C offers access time as fast as 55ns, allowing operation of high-speed microprocessors without wait states. To eliminate bus contention, the MX29F040C has separate chip enable (CE#) and output enable (OE#) controls.

MXIC's Flash memories augment EPROM functionality with in-circuit electrical erasure and programming. The MX29F040C uses a command register to manage this functionality. The command register allows for 100% TTL level control inputs and fixed power supply levels during erase and programming, while maintaining maximum EPROM compatibility

MXIC Flash technology reliably stores memory contents even after 100,000 erase and program cycles. The MXIC cell is designed to optimize the erase and program mechanisms. In addition, the combination of advanced tunnel oxide processing and low internal electric fields for erase and programming operations produces reliable cycling. The MX29F040C uses a 5.0V±10% VCC supply to perform the High Reliability Erase and auto Program/ Erase algorithms.

The highest degree of latch-up protection is achieved with MXIC's proprietary non-epi process. Latch-up protection is proved for stresses up to 100 milliamps on address and data pin from -1V to VCC + 1V.
