Introduction
The SH7020 and SH7021 are part of a new generation of reduced instruction-set computer-type
(RISC) microcomputers that integrate RISC-type CPUs and the peripheral functions required for
system configuration onto a single chip to achieve high-performance operations processing. They
can operate in a power-down state, which is an essential feature for portable equipment.
The SH7020 and SH7021 CPUs have RISC-type instruction sets. Basic instructions can be
executed in a single clock cycle, which strikingly improves instruction execution speed. The
SH7020 and SH7021 include peripheral functions such as large-capacity ROM (PROM or masked
ROM), RAM, a direct memory access controller (DMAC), timers, a serial communication
interface (SCI), an interrupt controller (INTC), and I/O ports. These on-chip elements enable
users to construct systems with the fewest possible components. External memory access support
functions enable direct connection to SRAM and DRAM. without the use of glue logics.
This Hardware Manual describes in detail the hardware functions of the SH7020 and SH7021. For
information on the instructions, please refer to the Programming Manual.
