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
The flash memory programming time is 10 ms (typ.) for simultaneous 32-byte programming,
equivalent to 300 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 H8S/2138 Group or H8S/2134 Group 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.
