Infineon Technologies S6E1C12C0AGN20000

Overview

S6E1C12C0AGN20000 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M0+ microcontroller with 128 KB Flash, 16 KB SRAM, and 40.8 MHz max CPU frequency. It operates from 1.65 V to 3.6 V, delivers 40 µA/MHz active power, and integrates USB 2.0 (Host/Device), six MFS serial interfaces (configurable as UART/SPI/I²C/I²S), 12-bit 1-Msps ADC with 8-channel mux, and hardware CRC accelerator - deployed in battery-powered IoT sensors and smart metering HMI systems.

For engineers reviewing the S6E1C12C0AGN20000 datasheet, S6E1C12C0AGN20000 pinout, S6E1C12C0AGN20000 application, or S6E1C12C0AGN20000 equivalent, key selection criteria include ultra-low-power operation (0.6 µA standby), fast 20 µs wake-up from deep standby, integrated USB PHY, dual I²S support, and IEC60730 Class B self-test library compatibility.

Technical Context

The S6E1C12C0AGN20000 implements an ARM Cortex-M0+ core with nested vectored interrupt controller (NVIC) supporting 24 peripheral interrupts and 4 priority levels, plus non-maskable interrupt (NMI). Its clock system includes main PLL, sub-oscillator, and dual built-in CR oscillators (8 MHz ±1.5%, 100 kHz ±10%) enabling flexible low-power timing modes.

Digital subsystem features a 64-channel descriptor-based transfer controller (DSTC), up to eight base timers, dual timer, watch counter, and real-time clock. Analog integration includes one 12-bit ADC with sample-and-hold, programmable gain, and hardware-triggered conversion sequences - all accessible via APB0/APB1 bridges and AHB interconnect.

FAQ

What is the maximum operating frequency and voltage range of the S6E1C12C0AGN20000?

The S6E1C12C0AGN20000 operates at up to 40.8 MHz with a supply voltage range of 1.65 V to 3.6 V. This range supports direct connection to common lithium coin cells (e.g., CR2032 nominal 3 V) and regulated 1.8 V/3.3 V rails, enabling design flexibility across portable and industrial power architectures.

Does the S6E1C12C0AGN20000 include hardware support for functional safety standards?

Yes - the device includes an IEC60730 Class B self-test library (AN205411) covering flash, RAM, clock, ADC, and CPU integrity checks. It also features dual watchdog timers (hardware and software), clock supervisor (CSV), and low-voltage detection - all documented for use in certified household appliance control systems.

How many serial communication interfaces does the S6E1C12C0AGN20000 support simultaneously?

The S6E1C12C0AGN20000 supports up to six Multi-Function Serial (MFS) interfaces, each configurable as UART, SPI, I²C, or I²S. In the 48-pin QFN package, all six are available with FIFO support on channels 4, 6, and 7 - enabling concurrent USB, display, sensor, and audio communication without CPU polling.

What debug interface does the S6E1C12C0AGN20000 use, and is JTAG supported?

The S6E1C12C0AGN20000 uses ARM Serial Wire Debug (SWD) with SWDIO and SWCLK pins - no JTAG support. SWD provides full debug, programming, and trace capability using only two pins, reducing PCB footprint and simplifying test fixture design versus traditional 5-pin JTAG.
