32 Megabit (4 Mb x 8-Bit),
CMOS 3.0 Volt-only Uniform Sector Flash Memory
General Description
The Am29LV033C is a 32 Mbit, 3.0 Volt-only Flash Memory. All read, program, and erase operations are accomplished using only a single power supply. The standard device offers access times of 70, 90, and 120 ns, allowing high speed microprocessors to operate without wait states. The device is offered in 63-ball FBGA and 40-pin TSOP packages.
