Infineon Technologies S6E1C32B0AGP20000

Overview

S6E1C32B0AGP20000 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 consumption, and integrates USB 2.0 (Host/Device), six MFS serial interfaces (configurable as UART/SPI/I²C/I²S), and a 12-bit 1-Msps 8-channel ADC - deployed in battery-powered IoT sensors and smart home appliance controllers.

For engineers reviewing the S6E1C32B0AGP20000 datasheet, S6E1C32B0AGP20000 pinout, S6E1C32B0AGP20000 application, or S6E1C32B0AGP20000 equivalent, key selection criteria include ultra-low-power standby current (0.6 µA), fast wake-up time (20 µs from Flash), integrated USB PHY, DSTC-based DMA capability, and IEC60730 Class B self-test library support.

Technical Context

The S6E1C32B0AGP20000 implements an ARM Cortex-M0+ core with Nested Vectored Interrupt Controller supporting 24 peripheral interrupts and 4 priority levels, plus a 24-bit SysTick timer for RTOS scheduling. Its clock system includes dual oscillators: 8 MHz high-speed CR (±1% typical) and 100 kHz low-speed CR, alongside main/sub crystal inputs and a main PLL supporting both crystal and CR sources.

Digital subsystem features include up to eight 16-bit base timers, one dual timer, one watch counter, and a Descriptor System Transfer Controller (DSTC) with 64 channels for autonomous peripheral-to-memory transfers. Analog integration comprises a single 12-bit ADC with 8-channel multiplexer, programmable sampling rate, and hardware-triggered conversion sequencing.

FAQ

What is the maximum operating frequency and voltage range of the S6E1C32B0AGP20000?

The S6E1C32B0AGP20000 operates at a maximum CPU frequency of 40.8 MHz across 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 at ~3.0 V) and regulated 1.8 V/3.3 V rails, with guaranteed performance down to 1.65 V at full speed per datasheet Section 11.2.

Does the S6E1C32B0AGP20000 include hardware support for functional safety standards?

Yes - the device includes built-in hardware features enabling IEC60730 Class B compliance, including lockstep-capable clock supervision (CSV), memory test logic for Flash and SRAM, and a dedicated self-test library (AN205411). These are implemented without external components and validated per Infineon's Class B certification documentation.

How many serial communication interfaces does the S6E1C32B0AGP20000 support, and what protocols are configurable?

The S6E1C32B0AGP20000 supports up to six Multi-Function Serial (MFS) interfaces, each configurable as UART, CSIO (SPI), I²C, or I²S. On the 32-pin LQFP package, four MFS channels are available (MFS0–MFS3), with MFS6 reserved for I²S and FIFO-enhanced operation - confirmed in Package Dependent Features Table (Page 6, Rev. *D).

Is there a development kit available for the S6E1C32B0AGP20000, and what does it include?

Yes - the FM0-64L-S6E1C3 Starter Kit is the official evaluation platform, featuring the S6E1C3-series MCU in 64-pin QFN, onboard USB debugger, micro-USB connector, expansion headers for all I/O, and preloaded firmware demonstrating USB device mode, ADC sampling, and low-power mode transitions - documented in Cypress Application Note AN210985.
