Alliance Memory AS29CF160x-55TIN Parallel NOR Flash Memories
Alliance Memory AS29CF160x-55TIN Parallel NOR Flash Memories are organized as 2,097,152 bytes of 8 bits or 1,048,576 words of 16 bits each. These memories use pins I/O0 to I/O7 for 8-bit data and pins I/O0 to I/O15 for 16-bit data. The AS29CF160x-55TIN Flash memories are available in 48-pin TSOP packages. These memories are designed to be programmed in-system with the standard system 5V VCC supply. The AS29CF160x-55TIN memories require only a single 5V power supply for both read and write functions. The program and erase functions use internally generated and regulated voltages.The AS29CF160x-55TIN Flash memories are entirely software command set compatible with the JEDEC single power supply flash standard. These memories feature sector-erase architecture that allows memory sectors to be erased and reprogrammed without affecting the data contents of the device. The power-saving features allow the device to be placed in standby mode with greatly reduced power consumption.
