1. Overview
1.1. Features
The S1C31D50 is a 32-bit ARM® Cortex®-M0+ MCU which integrates a specific hardware block called
the HW Processor. The HW Processor can perform 2ch Voice/Audio Play, Voice Speed Conversion, and
Self Memory Check without using any CPU resource. The S1C31D50 is suitable for home electronics,
white goods, and battery-based products which require voice and audio playback.
With the HW Processor, low memory footprint and multi-language support are achievable because of
its integrated high-compression algorithm for voice and audio.
