Product details
Overview
S6E1C31C0AGN20000 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 at 1.65–3.6 V. It integrates USB 2.0 (Host/Device), six configurable multi-function serial interfaces (UART/CSIO/SPI/I²C/I²S), a 12-bit 1-Msps 8-channel ADC, 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 S6E1C31C0AGN20000 datasheet, S6E1C31C0AGN20000 pinout, S6E1C31C0AGN20000 application, or S6E1C31C0AGN20000 equivalent, key selection criteria include its 40 µA/MHz active power, DSTC-based descriptor transfer controller, SW-DP debug interface, and package-specific peripheral availability (e.g., 64-pin LQFP enables full 6 MFS channels with FIFO).
Technical Context
The S6E1C31C0AGN20000 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 dual oscillators - a main crystal input (1–20 MHz), sub-clock (32.768 kHz), and built-in CR sources (8 MHz ±2%, 100 kHz ±10%) - feeding a programmable PLL for precise frequency synthesis.
Digital subsystem integration includes up to eight 16-bit base timers, one dual timer, one watch counter, and a 64-channel Descriptor System Transfer Controller (DSTC) for autonomous peripheral-to-memory transfers without CPU intervention. Analog features center on a single 12-bit ADC with 8-channel multiplexer, 1-Msps sampling, and hardware-triggered conversion sequencing.
