Product Classification
H8S/2110B
Size
Programming/erase methods
The flash memory is programmed 128 bytes at a time. Erase is performed in single-block units.
The flash memory is configured as follows:
To erase the entire flash memory, each block must be erased in turn.
Programming/erase time
It takes 10 ms (typ.) to program the flash memory 128 bytes at a time; 80 µs (typ.) per 1 byte.
Erasing one block takes 100 ms (typ.).
Reprogramming capability
The flash memory can be reprogrammed up to 100 times.
Two flash memory on-board programming modes
On-board programming/erasing can be done in boot mode in which the boot program built into
the chip is started for erase or programming of the entire flash memory. In user program mode,
individual blocks can be erased or programmed.
Automatic bit rate adjustment
With data transfer in boot mode, this LSI's bit rate can be automatically adjusted to match the
transfer bit rate of the host.
Programming/erasing protection
Sets protection against flash memory programming/erasing via hardware, software, or error
protection.
