26. 512K bit flash memory
The 512K bit flash memory is allocated in the FEH to FFH banks on the CPU memory map. Like masked ROM,
flash memory is read-accessible and program-accessible to the CPU using the flash memory interface circuit.
The flash memory can be programmed/erased by the instruction from the CPU via the flash memory interface
circuit. The flash memory can therefore be reprogrammed (updated) while still on the circuit board under
integrated CPU control, allowing program code and data to be improved efficiently.
Note that sector operations such as “enable sector protect” cannot be used.
Features of 512K bit flash memory :
64K words x 8 bits / 32K words x 16 bits (16K + 8K + 8K + 32K) sector configuration
Automatic program algorithm (same as the Embedded Algorithm* : MBM29F400TA)
Installation of the deletion temporary stop/delete restart function
Write/delete completion detected by the data polling or toggle bit
Write/delete completion detected by the CPU interrupt
Compatibility with the JEDEC standard-type command
Each sector deletion can be executed (Sectors can be freely combined)
Number of write/delete operations 10,000 times guaranteed
