EPSON Semiconductor has started shipping samples of the S1C31D50, a 32-bit microcontroller with dedicated sound hardware for 2-channel sound. Epson plans to produce 200000 units per model per month.

Sound is becoming increasingly popular in home electronic products, household appliances, industrial equipment, remote controls for health and fitness devices with guidance systems, and alarms in office buildings, shopping centers, and factories. This MCU is very suitable for all of these applications. An ARM-M0+processor with dedicated HW processor integration provides 2-channel sound on a single MCU chip. By using two channels, music and voice can be played simultaneously, making audio guidance more elegant and warm. The voice speed can also be flexibly adjusted.

The dedicated hardware processor of MCU has two special functions for sound hardware. Firstly, HW processors do not require CPU resources to play sound, so even during sound playback, CPU resources can be allocated to other processes. The use of high compression algorithms (16 kbps @ 16 kHz) reduces the size of sound data storage, making it possible to provide a large amount of sound data and sound data in multiple languages. Epson also offers PC tools that provide a development environment for easily creating sound data in Japanese, English, Chinese, and Korean without the need for recording.

Secondly, the MPU also has a self memory check function, which can detect faults in the built-in RAM, built-in flash memory, and external SPI Flash memory without using CPU resources.

Epson is committed to helping its customers improve their product performance by utilizing Epson's efficient, compact, and precision technology solutions.
