Four flash memory operating modes
Programming/erase methods
The flash memory is programmed 32 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, 8-kbyte, 16-kbyte, 28-kbyte, and 32-kbyte blocks.
Programming/erase times (5 V version)
The flash memory programming time is 10 ms (typ.) for simultaneous 32-byte programming, equivalent to 300 s
(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 H8S/2357 Group chip can be automatically adjusted to match the
transfer bit rate of the host.
Flash memory emulation by RAM
Part of the RAM area can be overlapped onto flash memory, to emulate flash memory updates in real time.
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.
