Infineon Technologies S6E1A11C0AGV20000

Overview

S6E1A11C0AGV20000 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 12-bit ADC (8 channels), LIN 2.1/UART/I²C/CSIO interfaces, 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 drives.

Technical Context

The S6E1A11C0AGV20000 implements a Cortex-M0+ r0p1 core with NVIC supporting 32 peripheral interrupts and 4 priority levels, plus SysTick and bit-band addressing. 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 four Base Timers (configurable as PWM/PPG/reload/PWC), three Multi-function Timers with input capture/output compare/ADC start triggers, and a dedicated Quadrature Position/Revolution Counter with 16-bit position/revolution counters and configurable AIN/BIN/ZIN edge detection for encoder interfacing.

FAQ

Does S6E1A11C0AGV20000 support in-system programming via SW-DP?

Yes. The device supports full in-system programming and debugging through its Serial Wire Debug Port (SW-DP) interface using standard ARM Cortex-M debug tools. Flash memory can be erased and reprogrammed in-circuit without removing the chip, and the Micro Trace Buffer enables real-time instruction trace for performance analysis and bug isolation during development.

What is the maximum operating temperature range for this MCU?

The S6E1A11C0AGV20000 is rated for industrial temperature range: –40 °C to +85 °C ambient. This is confirmed in Section 12.2 ("Recommended Operating Conditions") of the official datasheet (Document Number 002-05091 Rev. *E), and applies across all operating modes including STOP and RTC.

Can the QPRC operate while the CPU is in STOP mode?

No. The QPRC requires the peripheral clock (PCLK) to be active and is disabled in STOP mode. However, the Watch Counter - clocked by the sub-clock (32.768 kHz) - remains functional in STOP mode and can wake the CPU to service encoder events sampled prior to entry into STOP, enabling low-power periodic polling architectures.

Is the 12-bit ADC capable of simultaneous sampling across multiple channels?

No. The ADC is a single successive-approximation unit with multiplexed inputs. It supports scan conversion mode with up to 16-step FIFO for sequential channel sampling, but does not provide true simultaneous sampling. For synchronized acquisition, external analog multiplexing or parallel ADCs are required - a limitation explicitly stated in the "A/D Converter" section of the datasheet.
