32-bit Microcontrollers

Overview

The SH7261 is a high-performance microcontroller, incorporating an SH2A-FPU core. This LSI operates at a maximum operating frequency of 120MHz and incorporates single-precision and double-precision calculation-supporting FPU, which enables high-speed signal processing performance. In addition, this LSI includes peripheral functions such as a CD-ROM decoder implementing CD-ROM playback functions, an in-vehicle CAN controller, IEBusTM controller, serial sound interface (SSI) for digital audio data input/output, a serial communication interface with a 16-stage FIFO and I2C bus interface.
