Infineon Technologies S6E1A11C0AGN20000

Overview

S6E1A11C0AGN20000 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M0+ microcontroller with 88 KB on-chip Flash, 6 KB SRAM, and integrated peripherals including UART/CSIO/I²C/LIN interfaces, 12-bit ADC (8 channels, 0.8 µs conversion @5 V), RTC, QPRC, and dual watchdog timers. It operates at up to 40 MHz, supports 2.7–5.5 V supply, and targets low-power embedded control in industrial sensors and motor drive subsystems.

For engineers reviewing the S6E1A11C0AGN20000 datasheet, S6E1A11C0AGN20000 pinout, S6E1A11C0AGN20000 application, or S6E1A11C0AGN20000 equivalent, key selection criteria include its FM0+ architecture compatibility, 48-pin LQFP package with 37 fast GPIOs, LIN 2.1 support, 5 V-tolerant I/O capability, and dual-clock supervision with LVD1/LVD2 thresholds.

Technical Context

The S6E1A11C0AGN20000 implements the Arm Cortex-M0+ r0p1 core with NVIC supporting 32 peripheral interrupts and 4 priority levels, plus a 24-bit SysTick timer for RTOS integration. Its clock system integrates five sources - main oscillator (4–40 MHz), sub-clock (32.768 kHz), two CR oscillators (4 MHz / 100 kHz), and main PLL - enabling flexible low-power mode transitions across SLEEP, TIMER, RTC, and STOP states.

Peripheral integration includes three multi-function serial interfaces with FIFO-based full-duplex operation (UART/CSIO/LIN/I²C), a 12-bit successive-approximation ADC with scan/priority modes and 16-step FIFO, four base timers configurable as PWM/PPG/reload/PWC, and a dedicated Quadrature Position/Revolution Counter with AIN/BIN/ZIN edge configuration and dual 16-bit counters.

FAQ

What is the maximum operating frequency and core revision of the S6E1A11C0AGN20000?

The S6E1A11C0AGN20000 operates at a maximum frequency of 40 MHz and implements the Arm Cortex-M0+ processor core revision r0p1. This revision supports Thumb-2 instruction set, bit-band aliasing compatible with Cortex-M3, and a nested vectored interrupt controller with 32 peripheral interrupt lines and four programmable priority levels.

Does the S6E1A11C0AGN20000 support LIN communication, and what version is implemented?

Yes, the S6E1A11C0AGN20000 natively supports LIN protocol Revision 2.1 in both master and slave modes. It includes hardware features such as variable-length break field (13–16 bits), configurable break delimiter (1–4 bits), and built-in error detection for parity, framing, and overrun - eliminating software protocol stack overhead.

How many analog input channels and what ADC resolution does this MCU provide?

The S6E1A11C0AGN20000 integrates a single 12-bit successive approximation ADC with up to eight input channels. Conversion time is 0.8 µs at 5 V supply, and it supports scan mode with 16-step FIFO and priority conversion with 4-step FIFO - enabling efficient multi-sensor acquisition in real-time control loops.

What low-power modes are supported, and which ones retain RTC functionality?

The S6E1A11C0AGN20000 supports four low-power modes: SLEEP, TIMER, RTC, and STOP. Only RTC mode retains full Real-time Clock operation with calendar counting and alarm generation while minimizing current draw; STOP mode disables the RTC but preserves RAM and register contents using sub-clock backup.
