General Description
The MX29LV640T/B is a 64-mega bit Flash memory organized as 8M bytes of 8 bits or 4M bytes of 16 bits. MXIC’s Flash memories offer the most cost-effective and reliable read/write non-volatile random access memory. The MX29LV640T/B is packaged in 48-pin TSOP, 63- ball CSP and 64-ball Easy BGA. It is designed to be reprogrammed and erased in system or in standard EPROM programmers.
The standard MX29LV640T/B offers access time as fast as 90ns, allowing operation of high-speed microprocessors without wait states. To eliminate bus contention, the MX29LV640T/B 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 2 P/N:PM0920 REV. 1.2, NOV. 05, 2003 MX29LV640T/B MX29LV640T/B uses a command register to manage this functionality.
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 MX29LV640T/B uses a 2.7V to 3.6V 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 milliamperes on address and data pin from -1V to VCC + 1V.

Notes:
1. Minimum DC voltage on input or I/O pins is -0.5 V. During voltage transitions, input or I/O pins may overshoot VSS to -2.0 V for periods of up to 20 ns. See Figure 6. Maximum DC voltage on input or I/O pins is VCC +0.5 V. During voltage transitions, input or I/O pins may overshoot to VCC +2.0 V for periods up to 20 ns. See Figure 7.
2. Minimum DC input voltage on pins A9, OE, and RESET is -0.5 V. During voltage transitions, A9, OE, and RESET may overshoot VSS to -2.0 V for periods of up to 20 ns. See Figure 6. Maximum DC input voltage on pin A9 is +12.5 V which may overshoot to 14.0 V for periods up to 20 ns.
3. No more than one output may be shorted to ground at a time. Duration of the short circuit should not be greater than one second.
