4022” TFT TV Service Manual 13/10/200412.7. MX29LV160T12.7.1. General DescriptionThe MX29LV160T/B & MX29LV160AT/AB is a 16-megabit Flash memory organized as 2M bytes of 8 bitsor 1M words of 16 bits. MXIC's Flash memories offer the most cost-effective and reliable read/write non-volatile random access memory. The MX29LV160T/B & MX29LV160AT/AB 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 standardEPROM programmers.The standard MX29LV160T/B & MX29LV160AT/AB offers access time as fast as 70ns, allowing operationof high-speed microprocessors without wait states. To eliminate bus contention, the MX29LV160T/B&MX29LV160AT/AB 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 MX29LV160T/B & MX29LV160AT/AB uses a command register to manage this functionality. Thecommand register allows for 100% TTL level control inputs and fixed power supply levels during erase andprogramming, 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 programming mechanisms. In addition, thecombination of advanced tunnel oxide processing and low internal electric fields for erase and programoperations produces reliable cycling. The MX29LV160T/B & MX29LV160AT/AB uses a 2.7V~3.6V VCCsupply 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-upprotection is proved for stresses up to 100 milliamps on address and data pin from -1V to VCC + 1V.12.7.2.
