Product details
Overview
S6E1C31B0AGP20000 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 with RAM retention. It targets battery-powered IoT sensors and HMI systems requiring ultra-low-power operation and mixed-signal integration.
For engineers reviewing the S6E1C31B0AGP20000 datasheet, S6E1C31B0AGP20000 pinout, S6E1C31B0AGP20000 application, or S6E1C31B0AGP20000 equivalent, key selection criteria include its 12-bit 1-Msps ADC with 8-channel mux, DSTC-based DMA capability, SW-DP debug interface, and package-specific peripheral availability (e.g., 6× MFS, 2× I2S, Smart Card in 64-pin variants).
Technical Context
The S6E1C31B0AGP20000 implements a single-core ARM Cortex-M0+ processor with NVIC supporting 24 configurable peripheral interrupts plus NMI, and a 24-bit SysTick timer for RTOS scheduling. Its clock system integrates dual oscillators - an 8 MHz high-speed CR oscillator (±1% accuracy) and a 100 kHz low-speed CR oscillator - alongside main/sub crystal inputs and a main PLL for frequency synthesis.
Digital subsystem includes up to eight 16-bit base timers, one dual timer, one watch counter, and six multi-function serial interfaces (MFS) configurable as UART, SPI, I²C, or I²S. Analog features comprise one 12-bit, 1-Msps ADC with 8-channel analog multiplexer and two independent low-voltage detection (LVD) channels for supply monitoring.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32L072KBU6 | ARM Cortex-M0+, 32 MHz max, 128 KB Flash, 20 KB SRAM, no native USB - requires external PHY for USB. | Lacks integrated USB 2.0; supports AES hardware crypto not present in S6E1C31. | Select when cryptographic acceleration is prioritized over USB integration and lower active power is acceptable. |
| EFM32PG12B500F1024GL125 | ARM Cortex-M4, 40 MHz, 1024 KB Flash, 256 KB SRAM, USB 2.0, higher active power (116 µA/MHz). | Higher performance and memory, but 2.9× higher active current - unsuitable for coin-cell use cases. | Select when DSP-intensive firmware (e.g., FFT-based vibration analysis) justifies increased power budget and cost. |
