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.
