Infineon Technologies S6E1A11B0AGN2000G

Overview

S6E1A11B0AGN2000G from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M0+ microcontroller with 88 KB flash, 6 KB SRAM, and integrated LIN/UART/I²C/CSIO interfaces, operating up to 40 MHz at 2.7–5.5 V supply. It features a 12-bit ADC (8 channels, 0.8 µs conversion @5 V), RTC, QPRC encoder interface, and dual watchdog timers - deployed in automotive body control modules and industrial sensor nodes.

For engineers reviewing the S6E1A11B0AGN2000G datasheet, S6E1A11B0AGN2000G pinout, S6E1A11B0AGN2000G application, or S6E1A11B0AGN2000G equivalent, key selection criteria include LIN 2.1 compliance, 5 V-tolerant GPIO count (up to 37 pins in 48-pin LQFP), RTC leap-year support, hardware watchdog operation in STOP mode, and SW-DP debug with MTB trace capability.

Technical Context

The S6E1A11B0AGN2000G implements a Cortex-M0+ r0p1 core with NVIC supporting 32 peripheral interrupts and 4 priority levels, coupled with a 24-bit SysTick timer for RTOS scheduling. 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 - with Clock Supervisor (CSV) monitoring external clock failure via internal CR reference.

Peripheral integration includes three multi-function serial channels (each with 128-byte FIFO), four base timers configurable as PWM/PPG/reload/PWC, and a dedicated Quadrature Position/Revolution Counter with AIN/BIN/ZIN edge configuration, 16-bit position/revolution counters, and dual compare registers for motor position capture.

FAQ

What is the maximum operating frequency and supported voltage range?

The S6E1A11B0AGN2000G operates at up to 40 MHz with a supply voltage range of 2.7 V to 5.5 V. This wide range accommodates both 3.3 V logic systems and direct connection to automotive 12 V battery rails via internal LDO regulation, enabling single-supply designs without external regulators in many applications.

Does this MCU support hardware LIN 2.1 without external transceivers?

Yes - the S6E1A11B0AGN2000G includes a fully integrated LIN 2.1 protocol controller with break field generation, sync field handling, and checksum verification. It requires only an external LIN transceiver (e.g., TLE7259-3GE) for physical layer compliance, but all protocol-layer functions are implemented in hardware with zero CPU overhead.

How many I/O pins are 5 V tolerant, and which packages support them?

In the 48-pin LQFP package (GN2000G), 16 GPIO pins are 5 V tolerant - specifically P0_0 through P0_7 and P1_0 through P1_7 - as confirmed in Section 5 ("I/O Circuit Type") of the datasheet. These pins tolerate 5.5 V regardless of VCC level, simplifying interface with legacy 5 V sensors and actuators without level shifters.

Can the RTC maintain time accuracy during STOP mode, and what clock source does it use?

Yes - the RTC continues counting in STOP mode using the 32.768 kHz sub-clock oscillator (OSC32K). When paired with a precision external crystal, it achieves ±2 ppm accuracy and supports automatic leap-year calculation, enabling reliable timestamping for event logging and wake-up scheduling without waking the CPU.
