Infineon Technologies S6E2H46G0AGV20000

Overview

S6E2H46G0AGV20000 from Infineon Technologies is a 32-bit TRAVEO™ T2G Arm® Cortex®-M4 microcontroller designed for automotive body electronics applications. It integrates 2 MB flash, 384 KB SRAM, dual CAN FD controllers, 4x LIN transceivers, and hardware security (AES-128, SHA-256, TRNG). It operates at up to 144 MHz and supports AEC-Q100 Grade 2 qualification.

For engineers reviewing the S6E2H46G0AGV20000 datasheet, S6E2H46G0AGV20000 pinout, S6E2H46G0AGV20000 application, or S6E2H46G0AGV20000 equivalent, key selection criteria include CAN FD timing compliance, flash ECC implementation, secure boot configuration, and peripheral clock domain isolation in automotive ECU designs.

Technical Context

This MCU implements a dual-bank flash architecture with read-while-write capability and hardware-assisted flash error correction (ECC) across both banks. Its clock system includes a 4–20 MHz crystal oscillator input, PLLs supporting fractional division, and independent clock domains for CPU, peripherals, and safety monitors.

The device features a dedicated Safety Management Unit (SMU) with lockstep CPU core monitoring, memory built-in self-test (MBIST), and configurable watchdog timers. Peripheral interconnect uses a hierarchical AHB/APB bus matrix with configurable access rights and error injection support for functional safety validation.

FAQ

What is the maximum operating frequency of the S6E2H46G0AGV20000 CPU core?

The Arm® Cortex®-M4 core operates at a maximum frequency of 144 MHz, achieved via internal PLL with fractional divider and low-jitter clock synthesis. This frequency is guaranteed across the full AEC-Q100 Grade 2 temperature range (−40 °C to +125 °C) with appropriate voltage scaling and thermal management.

Does the S6E2H46G0AGV20000 support hardware-based secure boot?

Yes. The device includes a dedicated Secure Boot ROM that performs SHA-256 hash verification of the first 256-byte boot header and validates an ECDSA-P256 signature before loading application code. Keys are stored in one-time-programmable (OTP) fuses, and the boot process is immutable after factory programming.

How many independent CAN FD interfaces does the S6E2H46G0AGV20000 provide?

The S6E2H46G0AGV20000 integrates two fully independent CAN FD controllers compliant with ISO 11898-1:2015. Each supports bit rates up to 5 Mbps in the data phase, programmable sample points, and hardware message filtering with 128 configurable mailboxes per controller.

Is external memory required for typical automotive body control applications?

No. With 2 MB on-chip flash and 384 KB SRAM, the S6E2H46G0AGV20000 supports full application code, bootloader, calibration data, and runtime variables without external memory. Dual-bank flash allows background firmware updates while maintaining real-time control execution.
