SH7750 (SH-4 Series)
SuperHTM RISC Processor
Product Brief
Description
T he SH7750 (SH-4 series) is a high performance, cost-
effective, 2 issue superscalar RISC microprocessor
for embedded applications. The SuperHTM architecture is
the leader in code density among RISC microprocessors,
reducing memory costs in embedded applications. It
features a 64-bit external data bus, a 16-bit fixed-length
instruction set and a 128-bit vector graphics engine.
T he SH7750 is used in consumer, computing, multi-
media, and communication markets. Applications
include handheld PCs, sub-notebook PCs, Internet
appliances, set top boxes, and game machines. The
device can be paired with an ASSP companion device
for a low cost, low IC count, and differentiated system.
Hitachi optimized the SH7750 MMU, cache size, and
peripheral mix for Windows®CE applications.
