32-bit SuperH MCUs feature 1Mbyte of on-chip SRAM

San Jose, Calif.—Renesas Technology America Inc. has introduced two series of high-performance SuperH 32-bit microcontrollers (MCUs) with 1Mbyte of on-chip SRAM.

The 144MHz devices—the SH7262 and SH7264 series—are highly integrated and optimized for digital audio systems, MP3 media player accessories and graphical display systems, such as graphical dashboards for automobiles and industrial man-machine interfaces. Depending on a model, the MCUs have 18 to 20 peripheral functions that are sufficient for handling the many timing, communication, decompression, data conversion, and other tasks required in such applications.

These latest members of the SuperH family incorporate an SH2A-FPU CPU core with floating point unit (FPU) hardware that attains high code efficiency and runs application code quickly. Processing performance is 346 MIPS (Dhrystone 1.1 benchmark) and 288 MFLOPS at 144MHz.

Both the SH7262 and SH7264 series contain eight models—versions differentiated by temperature range (-20 to +85°C or -40 to +85°C) and whether or not they have CAN or IEBus interfaces. The SH7262 series MCUs are packaged in a 176-pin QFP and have four channels of A/D converter, while the SH7264 series devices come in a 208-pin QFP and have eight A/D converter channels. The QFP packages are lead-free types.

Pricing: Starts at $12 each in 10,000-piece quantities.
Availability: The third quarter of 2008.
