19.15.1 Features
The H8S/2398 F-ZTAT have 256 kbytes of on-chip flash memory. The features of the flash memory are summarized
below.
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). To
erase the entire flash memory, the individual blocks must be erased sequentially. Block erasing can be performed as
required on 4-kbyte, 32-kbyte, and 64-kbyte blocks.
Programming/erase times
The flash memory programming time is 10 ms (typ.) for simultaneous 128-byte programming, equivalent to 78 s
(typ.) per byte, and the erase time is 50 ms (typ.).
Reprogramming capability
Depending on the product, the maximum number of times the flash memory can be reprogrammed is either 100 or
1,000.
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.
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.
