1.1
This LSI (SH7750, SH7750S, and SH7750R Groups) is a 32-bit RISC (reduced instruction set
computer) microprocessor with a SH-4 CPU core and features upward compatibility with SH-1,
SH-2, and SH-3 microcomputers at the instruction set level. It includes an instruction cache, an
operand cache with a choice of copy-back or write-through mode, and an MMU (memory
management unit) with a 64-entry fully-associative unified TLB (translation lookaside buffer).
The SH7750 and SH7750S have an 8-Kbyte instruction cache and a 16-Kbyte data cache. The
SH7750R has a 16-Kbyte instruction cache and a 32-Kbyte data cache.
This LSI has an on-chip bus state controller (BSC) that allows connection to DRAM and
synchronous DRAM. 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 this LSI are summarized in table 1.1.
