Section 18 Flash Memory [H8/3024F-ZTAT Version]
18.2
The H8/3024F-ZTAT version has 128 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 in block units. To
erase the entire flash memory, each block must be erased in turn. In block erasing, 1-kbyte, 28-
kbyte, and 32-kbyte blocks can be set arbitrarily.
Programming/erase times
The flash memory programming time is 10 ms (typ.) for simultaneous 128-byte programming,
equivalent approximately to 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. A
function is also provided specially in boot mode for identifying a program transferred from the
host side:
Automatic bit rate adjustment
For data transfer in boot mode, the H8/3024F-ZTAT version chip’s bit rate can be
automatically adjusted to match the transfer bit rate of the host.
Flash memory emulation in RAM
Flash memory programming can be emulated in real time by overlapping a part of RAM onto
flash memory.
Protect modes
There are three protect modes—hardware, software, and error—which allow protected status
to be designated for flash memory program/erase/verify operations
Program mode
Erase mode
Program-verify mode
Erase-verify mode
Boot mode
User program mode
