Renesas Technology has introduced the SH72546R SuperH 1 Family microcontroller designed for use in automotive engine and transmission control systems.

The device combines high-speed operation of up to 200MHz with flash memory capacity of 3.75Mbyte.

The SH72546R incorporates the same SH-2A high-end core as the earlier devices in the series.

This core, having a superscalar structure and Harvard architecture, achieves 400MIPS at 200MHz operation, enabling it to achieve sophisticated real-time control involving more complex operation processing demanded by engine or transmission control applications.

The device is able to operate in ambient temperatures up to 125°C, an essential feature for automotive applications.

The device features a 12-bit A/D converter, CAN interface, and high-speed serial interface functions.
