21B.4 Flash Memory Overview
21B.4.1 Features
The H8S/2638 and H8S/2639 have 256 kbytes of on-chip flash memory, or 256 kbytes of on-chip
mask ROM. The H8S/2630 has 384 kbytes of on-chip flash memory, or 384 kbytes of on-chip
mask ROM. The features of the flash memory are summarized below.
• Four flash memory operating modes
• Programming/erase methods
• Programming/erase times
• Reprogramming capability
• On-board programming modes
• Automatic bit rate adjustment
• Flash memory emulation in RAM
• Protect modes

⎯ Program mode
⎯ Erase mode
⎯ Program-verify mode
⎯ Erase-verify mode
The flash memory is programmed 128 bytes at a time. Block erase (in single-block units) can
be performed. To erase the entire flash memory, each block must be erased in turn. Block
erasing can be performed as required on 4 kbytes, 32 kbytes, and 64 kbytes blocks.
The flash memory programming time is 10 ms (typ.) for simultaneous 128-byte programming,
equivalent to 80 µs (typ.) per byte, and the erase time is 100 ms (typ.).
The flash memory can be reprogrammed up to 100 times.
There are two modes in which flash memory can be programmed/erased/verified on-board:
⎯ Boot mode
⎯ User program mode
With data transfer in boot mode, the LSI’s bit rate can be automatically adjusted to match the
transfer bit rate of the host.
Flash memory programming can be emulated in real time by overlapping a part of RAM onto
flash memory.
There are three protect modes, hardware, software, and error protection, which allow protected
status to be designated for flash memory program/erase/verify operations.
