SH7055
Product Overview:
The SH7055 is a single-chip RISC (reduced instruction set computer) microcomputer that has an original Renesas RISC type CPU as its core, and also includes peripheral functions necessary for system configuration.
The CPU of the SH7055 has a RISC type instruction set, with basic instructions executed in one system clock cycle, for a higher instruction execution speed. It employs an internal 32-bit configuration, and offers enhanced data processing performance. The CPU of the SH7055 makes it possible to create high-performance, high-functionality systems at low cost, even for applications requiring high speed such as real-time control, which could not be realized with conventional microcomputers.
The SH7055 is also equipped with on-chip peripheral functions necessary for system configuration, including a floating-point unit (FPU), large-capacity ROM and RAM, a direct memory access controller (DMAC), timers, a serial communication interface (SCI), Renesas controller area network (HCAN), A/D converter, interrupt controller (INTC), and I/O ports.
In addition, an external memory access support function allows direct connection of ROM and SRAM, enabling system costs to be greatly reduced.
The SH7055 is an F-ZTAT™ (Flexible Zero Turn-Around Time) version with flash memory as its on-chip ROM. Flash memory programs can be written with a programmer that supports SH7055 programming, and the flash memory can also be programmed and erased by software. This allows reprogramming to be carried out by the user with the chip mounted on a board.
