Notes: 1. Minimum DC voltage on input or l/O pins is -0.5 V. During voltage transitions, input or I/O pins may undershoot VSS to -2.0 V for periods of up to 20 ns. Maximum DC voltage on input or l/O pins is VCC +0.5 V. During voltage transitions, input or I/O pins may overshoot to VCC +2.0 V for periods of up to 20 ns.
2. Minimum DC input voltage on A9, OE, ACC, and RESET pins is 0.5 V. During voltage transitions, A9,OE, ACC, and RESET pins may undershoot VSS to -2.0 V for periods of up to 20 ns. Voltage difference between input and supply voltage (VIN-VCC) does not exceed 9.0 V. Maximum DC input voltage on A9,OE, ACC, and RESET pins is +13.0 V which may overshoot to +14.0 V for periods of up to 20 ns.
DescriptionThe MBM29LV652UE-90/12 is a 64M-bit, 3.0 V-only Flash memory organized as 4M words of 16 bits each. The device is designed to MBM29LV652UEbe programmed in system with the standard system 3.0 V VCC supply. 12.0 V VPP and 5.0 V VCC are not required for write or erase operations. MBM29LV652UE-90/12 can also be reprogrammed in standard EPROM programmers.
To eliminate bus contention the devices have separate chip enable (CE), write enable (WE), and output enable (OE) controls.
The MBM29LV652UE-90/12 is entirely command set compatible with JEDEC single-power-supply Flash standard.Commands are written to the command register using standard microprocessor write timings. Register contents serve as input to an internal state-machine which controls the erase and programming circuitry. Write cycles also internally latch addresses and data needed for the programming and erase operations.Typically, each sector can be programmed and verified in about 0.5 seconds.
