SH7020, SH7021

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.

Hardware Design Support

Title Description
IBIS/BSDL

IBIS standard simulation data is required for high-speed board design and can be used to run simulations to examine and troubleshoot issues such as waveform reflection, ringing, and so on, before producing the actual board.

BSDL is a data input format supported by most IEEE 1149.1 (JTAG)-compliant tools. The automatic test pattern generation (ATPG) and automatic test equipment functions of these tools facilitate testing.
