Product details
Overview
S6E1C32B0AGU1H040 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 - deployed in battery-powered IoT sensors and smart metering endpoints.
For engineers reviewing the S6E1C32B0AGU1H040 datasheet, S6E1C32B0AGU1H040 pinout, S6E1C32B0AGU1H040 application, or S6E1C32B0AGU1H040 equivalent, key selection criteria include its 12-bit 1-Msps ADC with 8-channel mux, DSTC-based descriptor transfer controller, SW-DP debug interface, and package-specific peripheral mapping for LQFP-48.
Technical Context
The S6E1C32B0AGU1H040 implements an ARM Cortex-M0+ core with NVIC supporting 24 peripheral interrupts and 4 priority levels, coupled with a 24-bit SysTick timer for RTOS scheduling. Its clock system integrates dual oscillators - 8 MHz high-speed CR and 100 kHz low-speed CR - plus main/sub crystal inputs and a main PLL supporting both crystal and CR sources.
Digital subsystem includes up to 6 configurable MFS interfaces (UART/CSIO/SPI/I²C), 2x I²S, 2x HDMI-CEC, Smart Card interface, and 8x base timers with PWM/PPG capability. Analog integration centers on a single 12-bit ADC with 8-channel multiplexer and hardware-triggered conversion timing.

FAQ
What is the maximum operating frequency and voltage range for S6E1C32B0AGU1H040?
The S6E1C32B0AGU1H040 operates at up to 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 or 3.3 V rails. The device maintains full functionality-including USB and ADC-across the entire voltage window, with specified AC/DC characteristics validated per datasheet Section 11.
Does S6E1C32B0AGU1H040 include hardware security features?
Yes. It includes flash security bits that prevent unauthorized readout of program memory, a unique 128-bit device ID for secure provisioning, and hardware-accelerated CRC-32 for data integrity verification. These features support IEC60730 Class B compliance and are leveraged in AN205411 for self-test implementation - enabling certified safety-critical applications in appliances and industrial controls.
How many communication interfaces does S6E1C32B0AGU1H040 support simultaneously?
The device supports up to six Multi-Function Serial (MFS) interfaces, each configurable as UART, SPI, I²C, or I²S. In the 48-pin LQFP package, up to four MFS channels are available (Ch.0/1/3 without FIFO, Ch.6 with FIFO), plus dedicated USB 2.0, two I²S, two HDMI-CEC, and one Smart Card interface - allowing concurrent use of USB + UART + I²C + SPI in typical designs without resource conflict.
What low-power modes are available and how fast is wake-up from standby?
Six low-power modes are supported: Sleep, Timer, RTC, Stop, Deep Standby RTC, and Deep Standby Stop - all configurable with RAM retention options. Wake-up from Deep Standby RTC mode takes 20 µs (typical) when executing from Flash, enabling rapid response to external interrupts or RTC alarms while maintaining sub-µA quiescent current - verified in datasheet Section 11.9.1.
