Epson Shipping Samples of the Latest Addition to Its Series of 32-Bit MCUs with Sound Playback Hardware

S1C31D41 provides same usability as its predecessors but with voice pitch conversion and built-in clock with ±1% accuracy

Seiko Epson Corporation (TSE: 6724, "Epson") has begun shipping samples of the 96 KB Flash memory S1C31D41, the latest addition to Epson's series of 32-bit microcontrollers (MCUs) with dedicated sound playback hardware. Epson plans to produce 200,000 units per month.

Sound is becoming an increasingly popular feature in home electronics, remote controllers for home appliances, industrial devices, health and fitness equipment with guidance systems, and alarms in office buildings, shopping complexes, and factories. The S1C31D41 is the ideal microcontroller for sound playback in this type of equipment, where built-in memory and wide pin pitch packages are desirable.

The S1C31D41 is equipped with 96 KB of Flash memory, an amount suitable for products in the target field. In addition to voice speed conversion function, a new voice pitch conversion function allows voice to be set at a pitch that is easy to hear. The MCU is also equipped with an internal clock that is accurate to ±1%(0 - 85℃), which enables customers to reduce the number of external components.

Like the earlier S1C31D50 and S1C31D51, which have 192 KB of Flash memory, the new MCU is a highly versatile 32-bit Arm® Cortex®-M0 + RISC processor with a dedicated HW processor. The HW processor is a sound playback circuit that performs 2-channel mixing, voice speed/pitch conversion, and buzzer melody/voice playback without using CPU resources.

Epson also helps to streamline the voice data creation process by providing a voice creation PC tool that supports 12 languages, so customers can easily create multilingual voice data without the need for studio recording and, possible to use WAV data that they already have.

Epson will help customers further improve the performance of their products and contribute to smart social infrastructure by leveraging its efficient, compact, and precision technologies to save energy, save space, and deliver exceptional precision and accuracy.
