Infineon Technologies S6E1C12B0AGP20000

Overview

S6E1C12B0AGP20000 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M0+ microcontroller with 128 KB Flash, 16 KB SRAM, and operation at up to 40.8 MHz across 1.65–3.6 V. It integrates a 12-bit 1-Msps ADC (8-channel), six configurable MFS interfaces (UART/SPI/I²C/I²S), USB 2.0 host/device, and ultra-low-power modes including deep standby with RTC retention. It targets battery-powered IoT sensors and smart home appliance controllers.

For engineers reviewing the S6E1C12B0AGP20000 datasheet, S6E1C12B0AGP20000 pinout, S6E1C12B0AGP20000 application, or S6E1C12B0AGP20000 equivalent, key selection criteria include its 40 µA/MHz active power, 0.6 µA standby current, 20 µs wake-up time from standby, integrated USB PHY, and support for IEC60730 Class B functional safety compliance via on-chip self-test library.

Technical Context

The S6E1C12B0AGP20000 implements the ARM Cortex-M0+ core with Nested Vectored Interrupt Controller (NVIC) supporting 24 peripheral interrupts and 4 priority levels, plus a non-maskable interrupt. Its clock system includes dual oscillators - an external main crystal (up to 40 MHz), sub-crystal (32.768 kHz), and two internal CR oscillators (8 MHz ±2% and 100 kHz ±10%) - managed by a programmable PLL for precise frequency synthesis.

DMA-like data movement is handled by the Descriptor System Transfer Controller (DSTC) with 64 channels, enabling autonomous peripheral-to-memory transfers without CPU intervention. Peripheral integration follows FM0+ TYPE3-M0+ architecture: all serial interfaces (MFS) share common register sets but differ in FIFO depth and supported protocols per channel, while USB operates in full-speed mode with integrated PHY and endpoint controller.

FAQ

What is the maximum operating frequency and voltage range for S6E1C12B0AGP20000?

The S6E1C12B0AGP20000 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 single-cell Li-ion, LiPo, or alkaline battery sources without external regulation in many applications. The 40.8 MHz specification is validated across the full voltage and temperature range per Section 11.2 of Document 002-00233 Rev. *D.

Does S6E1C12B0AGP20000 include an integrated USB PHY?

Yes, the S6E1C12B0AGP20000 integrates a full-speed USB 2.0 PHY compliant with USB Specification Revision 2.0. Pins UDP0 and UDM0 provide differential D+/D− signals with on-die termination and ESD protection, eliminating the need for external transceivers or discrete protection components in most designs.

How many ADC channels does S6E1C12B0AGP20000 support, and what is its sampling rate?

The device features a single 12-bit successive-approximation ADC with an 8-channel analog multiplexer, capable of 1 million samples per second (1-Msps). Conversion results are accessible via DMA or interrupt-driven reads, and the ADC supports hardware averaging across up to 16 samples to improve effective resolution in noisy environments.

Is IEC60730 Class B compliance supported out-of-the-box?

Yes - Infineon provides the AN205411 IEC60730 Class B Self-Test Library, which implements required tests for RAM, Flash, clock, and ADC functionality. The library is pre-validated for S6E1C12 and integrates directly into ModusToolbox™ projects, enabling certified functional safety without custom test development.
