Section 1 Overview and Pin Functions
1.1
SH7708 Series Features
The SH7708, SH7708S, and SH7708R(SH7708 Series) are 32-bit RISC (reduced instruction set
computer) microcomputers, featuring object code upward-compatibility with SH-1 and SH-2
microcomputers. The SH7708R is completely pin compatible with the SH7708S. It includes an 8-
kbyte cache with a choice of write-back or write-through mode, and an MMU (memory
management unit) with a 128-entry 4-way set associative TLB (translation lookaside buffer).
The SH7708 Series has an on-chip bus state controller (BSC) that allows direct connection to
DRAM, synchronous DRAM (SDRAM), and pseudo-SRAM (PSRAM) without external circuitry.
Its 16-bit fixed-length instruction set enables program code size to be reduced by almost 50%
compared with 32-bit instructions.
The features of the SH7708 Series are summarized in table 1.1.
