Infineon Technologies S6E1C32B0AGU1H020

Overview

S6E1C32B0AGU1H020 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-targeted for battery-powered IoT sensors and portable HMI systems.

For engineers reviewing the S6E1C32B0AGU1H020 datasheet, S6E1C32B0AGU1H020 pinout, S6E1C32B0AGU1H020 application, or S6E1C32B0AGU1H020 equivalent, key selection criteria include its 12-bit 1-Msps ADC with 8-channel mux, dual I2S interfaces, DSTC-based DMA capability, and SW-DP debug support-critical for ultra-low-power embedded control in resource-constrained designs.

Technical Context

The S6E1C32B0AGU1H020 implements a tightly coupled 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 integrates dual oscillators: an 8 MHz high-speed CR oscillator (±2% accuracy) and a 100 kHz low-speed CR oscillator, alongside main/sub crystal inputs and a programmable PLL.

Digital subsystem includes up to 6 configurable MFS serial interfaces (UART/SPI/I²C), 2x I2S channels with FIFO, HDMI-CEC/remote receiver, Smart Card interface, and a 64-channel Descriptor System Transfer Controller (DSTC) enabling autonomous data movement without CPU intervention-reducing active time in sensor aggregation and audio streaming tasks.

FAQ

What is the maximum operating frequency and voltage range for S6E1C32B0AGU1H020?

The S6E1C32B0AGU1H020 operates at up to 40.8 MHz across a supply voltage range of 1.65 V to 3.6 V. This range supports single-cell Li-ion, two-cell alkaline, and regulated 3.3 V systems without level-shifting. The 40.8 MHz specification is validated under recommended operating conditions per Section 11.2 of Document 002-00233 Rev. *D.

Does S6E1C32B0AGU1H020 support USB device mode without external components?

Yes. S6E1C32B0AGU1H020 integrates a full-speed USB 2.0 PHY with on-die termination resistors and internal voltage regulators, enabling standalone USB device operation (e.g., CDC, HID, MSC classes) using only the USB_DP/USB_DM pins and standard USB connector-no external transceiver or VBUS sensing circuitry required.

How many ADC channels and what resolution does the built-in analog-to-digital converter provide?

The device includes one 12-bit successive approximation register (SAR) ADC with 8 input channels (AN0–AN7), capable of 1 million samples per second (1-Msps). Channel selection, sampling time, and trigger sources (timer, software, external) are fully configurable via dedicated registers, and conversion results are accessible via memory-mapped registers or DSTC transfer.

Is IEC60730 Class B compliance supported in hardware and firmware?

Yes. S6E1C32B0AGU1H020 provides hardware features required for IEC60730 Class B-including clock supervision (CSV), low-voltage detection (LVD), RAM/Flash integrity checking, and watchdog timers-and ships with AN205411, a certified self-test library that implements all mandatory tests (e.g., ROM checksum, RAM march test, CPU ALU check) with documented pass/fail reporting.
