Product details
Overview
S6E1C31C0AGV20000 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M0+ microcontroller with 128 KB Flash, 16 KB SRAM, and integrated USB 2.0 host/device interface. It operates from 1.65 V to 3.6 V at up to 40.8 MHz, delivers 40 µA/MHz active power consumption, and supports six low-power modes including Deep Standby RTC. It targets battery-powered IoT sensors and smart home appliance controllers requiring real-time ADC, multi-protocol serial interfaces, and secure firmware execution.
For engineers reviewing the S6E1C31C0AGV20000 datasheet, S6E1C31C0AGV20000 pinout, S6E1C31C0AGV20000 application, or S6E1C31C0AGV20000 equivalent, key selection criteria include its 12-bit 1-Msps ADC with 8-channel mux, DSTC-based DMA efficiency, SW-DP debug interface, and IEC60730 Class B self-test library support for safety-critical embedded control.
Technical Context
The S6E1C31C0AGV20000 implements a tightly coupled AHB-APB bus architecture with dual-layer AHB interconnect, enabling concurrent CPU access and peripheral DMA via the 64-channel Descriptor System Transfer Controller (DSTC). Its clock system integrates dual oscillators - 8 MHz high-speed CR and 100 kHz low-speed CR - plus external crystal support and a main PLL for flexible frequency synthesis.
Peripheral subsystems include six configurable Multi-Function Serial (MFS) interfaces supporting UART, SPI, I²C, I²S, Smart Card, and HDMI-CEC; a 12-bit ADC with hardware-triggered sampling and programmable gain; and dual watchdog timers (hardware + software) with Clock Supervisor (CSV) for fault detection in safety-aware designs.
Key Specifications

Pinout & Package
S6E1C31C0AGV20000 uses a 48-pin QFN package (WNY048, 0.50 mm pitch) with exposed thermal pad. Pin functions are defined per I/O port relocation capability, supporting dynamic remapping of MFS, ADC, and timer signals to optimize PCB layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Dual VDD/VSS pairs ensure stable core and I/O domain operation across 1.65–3.6 V range; thermal pad improves heat dissipation in compact enclosures. |
| P00–P07, P10–P17, P20–P27, P30–P37 | General-purpose I/O ports | 48 total GPIO pins with configurable pull-up/down, open-drain, and slew-rate control - support touch sensing, LED driving, and level-shifted interface bridging. |
| AN0–AN7 | ADC analog inputs | Dedicated pins mapped to internal 8-channel mux - enable simultaneous sampling of thermistors, shunt resistors, and reference voltages without external multiplexing. |
| USB_DP/USB_DM | USB differential data lines | Full-speed USB 2.0 transceiver with internal termination - eliminates need for external ESD protection diodes in cost-sensitive consumer HMI designs. |
| SWDIO/SWCLK | Serial Wire Debug interface | 2-pin debug channel supporting flash programming, real-time variable inspection, and breakpoint debugging without dedicated JTAG header space. |
Key Features
| Feature | Design Value |
|---|---|
| DSTC (Descriptor System Transfer Controller) | 64-channel hardware DMA engine offloads CPU during ADC-to-memory transfers, UART streaming, or USB packet handling - reduces active time by >30% in sensor fusion workloads. |
| IEC60730 Class B Self-Test Library | Pre-certified firmware library validates RAM, Flash, CPU registers, clock monitor, and ADC functionality - accelerates functional safety certification for home appliance control units. |
| Multi-Function Serial (MFS) Interfaces | 6 configurable serial channels supporting UART, SPI, I²C, I²S, Smart Card, and HDMI-CEC on shared pins - eliminates need for external protocol translators in remote-controlled appliances. |
| Ultra-Low-Power RTC with Deep Standby | Real-time clock maintains timekeeping with <1 µA draw while retaining SRAM content - enables scheduled wake-up for periodic environmental monitoring without external RTC IC. |
| Built-in Oscillators | 8 MHz high-speed CR (±2%) and 100 kHz low-speed CR (±10%) - eliminate external crystals in cost-sensitive designs while meeting USB suspend/resume timing requirements. |
