Four flash memory operating modes
Programming/erase methods
The flash memory is programmed 128 bytes at a time. Erasing is performed by block erase (in
single-block units). When erasing multiple blocks, the individual blocks must be erased
sequentially. Block erasing can be performed as required on 1-kbyte, 28-kbyte, 16-kbyte, 8-
kbyte, and 32-kbyte blocks.
Programming/erase times
The flash memory programming time is 10 ms (typ.) for simultaneous 128-byte programming,
equivalent to approximately 80 µs (typ.) per byte, and the erase time is 100 ms (typ.) per block.
Reprogramming capability
The flash memory can be reprogrammed up to 100 times.
On-board programming modes
There are two modes in which flash memory can be programmed/erased/verified on-board:
Automatic bit rate adjustment
With data transfer in boot mode, the bit rate of the chip can be automatically adjusted to match
the transfer bit rate of the host.
Protect modes
There are three protect modes, hardware, software, and error protect, which allow protected
status to be designated for flash memory program/erase/verify operations.
Programmer mode
Flash memory can be programmed/erased in programmer mode, using a PROM programmer,
as well as in on-board programming mode.
