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.
