特性 Features

The SH7052F/SH7053F/SH7054F is a single-chip RISC microcontroller that integrates a RISC CPU core using an original Hitachi architecture with peripheral functions required for system configuration.

The CPU has a RISC-type instruction set. Basic instructions can be executed in one state (one system clock cycle), which greatly improves instruction execution speed. In addition, the 32-bit internal architecture enhances data processing power. With this CPU, it has become possible to assemble low-cost, high-performance/high-functionality systems even for applications such as real-time control, which could not previously be handled by microcontrollers because of their high-speed processing requirements.

In addition, the SH7052F/SH7053F/SH7054F includes on-chip peripheral functions necessary for system configuration, such as ROM , RAM, a direct memory access controller (DMAC), timers, a serial communication interface (SCI), Hitachi controller area network (HCAN), A/D converter, interrupt controller (INTC), and I/O ports.

ROM and SRAM can be directly connected by means of an external memory access support function, greatly reducing system cost.

On-chip ROM is available as flash memory in the F-ZTAT™* (Flexible Zero Turn Around Time) version. The flash memory can be programmed with a programmer that supports SH7052F/SH7053F/SH7054F programming, and can also be programmed and erased by software. This enables the chip to be programmed at the user site while mounted on a board.
