H8SX/1668
The start addresses of two memory spaces (memory MATs) are allocated to the same address.
The mode setting in the initiation determines which memory MAT is initiated first. The
memory MATs can be switched by using the bank-switching method after initiation.
 User MAT initiated at a reset in user mode: 384 Kbytes/512 Kbytes/1 Mbyte
 User boot MAT is initiated at reset in user boot mode: 16 Kbytes
This LSI has a programming/erasing program. After downloading this program to the on-chip
RAM, programming/erasure can be performed by setting the parameters.
Programming time: 1 ms (typ.) for 128-byte simultaneous programming
Erasing time: 600 ms (typ.) per 1 block (64 Kbytes)
The number of programming can be up to 100 times at the minimum. (1 to 100 times are
guaranteed.)
SCI Boot mode: Using the on-chip SCI_4, the user MAT and user boot MAT can be
programmed/erased. In SCI boot mode, the bit rate between the host and this LSI can be
adjusted automatically.
USB boot mode: Using the on-chip USB, the user MAT can be programmed/erased.
