Infineon Technologies S6E1C31D0AGV20000

Overview

S6E1C31D0AGV20000 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M0+ microcontroller with 128 KB Flash, 16 KB SRAM, and operation up to 40.8 MHz across 1.65–3.6 V. It integrates USB 2.0 (Host/Device), 6-channel MFS (configurable as UART/SPI/I²C/I²S), 12-bit 1-Msps ADC with 8-channel mux, and ultra-low-power modes including Deep Standby RTC (0.6 µA). It targets battery-powered IoT sensors and HMI systems requiring fast wake-up (20 µs from standby) and IEC60730 Class B compliance.

For engineers reviewing the S6E1C31D0AGV20000 datasheet, S6E1C31D0AGV20000 pinout, S6E1C31D0AGV20000 application, or S6E1C31D0AGV20000 equivalent, key selection criteria include its 40 µA/MHz active power, 35 µA/CoreMark® efficiency score, dual timer + watch counter for time-critical control, SW-DP debug interface, and package-specific peripheral availability (e.g., 64-pin LQFP enables full 6-MFS + 2×I²S + Smart Card support).

Technical Context

The S6E1C31D0AGV20000 implements an ARM Cortex-M0+ core with NVIC supporting 24 peripheral interrupts and 4 priority levels, plus a 24-bit SysTick timer for RTOS scheduling. Its clock system includes main PLL (with 8 MHz CR or external crystal input), sub-oscillator, and dual CR oscillators (8 MHz high-speed ±1.5%, 100 kHz low-speed ±10%).

DSTC provides 64-channel descriptor-based DMA for offloading CPU from data movement across AHB/APB domains. Peripheral subsystem includes Base Timers (8×16-bit/4×32-bit), Dual Timer, Watch Counter, Real-Time Clock, and CRC accelerator - all accessible via APB0/APB1 bridges with configurable clock gating for dynamic power control.

FAQ

What is the maximum operating frequency and voltage range for S6E1C31D0AGV20000?

The S6E1C31D0AGV20000 operates at up to 40.8 MHz across a supply voltage range of 1.65 V to 3.6 V. This range supports direct interfacing with common battery chemistries including single-cell Li-ion (3.0–3.7 V nominal), two-cell alkaline (3.0 V), and 3 V coin cells - with guaranteed timing margins and flash write functionality down to 1.65 V.

Does S6E1C31D0AGV20000 support IEC60730 Class B functional safety certification?

Yes - the device includes hardware features required for Class B compliance, including CRC accelerator, memory parity/ECC on SRAM, clock supervision (CSV), and low-voltage detection (LVD) with interrupt and reset outputs. Cypress provides AN205411, a validated self-test library implementing required tests (RAM, Flash, CPU, clock, ADC), enabling certified firmware development without external safety monitors.

How many serial communication interfaces does S6E1C31D0AGV20000 support in the 64-pin LQFP package?

In the 64-pin LQFP (LQD064) package, the S6E1C31D0AGV20000 supports up to six Multi-Function Serial (MFS) interfaces - configurable individually as UART, CSIO (SPI), I²C, or I²S. Channels 4 and 6 support I²S with FIFO, and channels 0, 1, and 3 operate without FIFO; this enables concurrent use of display (SPI), audio (I²S), and sensor (I²C) interfaces without software arbitration.

What debug interface is supported, and is JTAG required?

The S6E1C31D0AGV20000 supports Serial Wire Debug (SW-DP) using only SWCLK and SWDIO pins - no JTAG TAP is needed. This 2-pin interface provides full flash programming, real-time variable inspection, and breakpoint control. The device does not support legacy JTAG; SW-DP is mandatory for development and production programming, and is compatible with standard ARM debug probes (e.g., Segger J-Link, ST-Link v2-1).
