2. Flash Memory
The F29C51001T/F29C51001B is a 1 Megabit, 5.0 Volt-only Flash Memory organized as 131,072
bytes of 8 bits each. This device is designed to use a 4.7 Volt to 5.3 Volt power supply to perform
in-system programming.
The 1 Megabit memory array is divided into thirty-two uniform blocks of 4 Kbytes each for data and/or
code storage.
The block architecture allows users to flexibly make chip erase or block erase operation. The block
erase feature allows a particular block to be erased and reprogrammed without affecting the data in
other blocks. After the device performs chip erase or block erase operation, it can be reprogrammed on
a byte-by-byte basis.
