Infineon Technologies CYT2B94CACQ0AZEGST

Overview

CYT2B94CACQ0AZEGST from Infineon is a dual-core automotive microcontroller featuring a 160-MHz Arm® Cortex®-M4F CPU and a 100-MHz Arm® Cortex®-M0+ CPU, 2112-KB code-flash with RWW support, 256-KB SRAM, and integrated CAN FD (up to 8 channels), LIN (up to 12 channels), and CXPI (up to 4 channels). It targets body control modules requiring ASIL-B functional safety, secure boot, and hardware crypto acceleration (AES-128/192/256, SHA-256/512, ECC, TRNG).

For engineers reviewing the CYT2B94CACQ0AZEGST datasheet, CYT2B94CACQ0AZEGST pinout, CYT2B94CACQ0AZEGST application, or CYT2B94CACQ0AZEGST equivalent, this page delivers verified technical context, package-specific pin mapping, real-world use cases in automotive body electronics, and validated alternative parts for design continuity and supply resilience.

Technical Context

The CYT2B94CACQ0AZEGST implements a tightly coupled dual-CPU architecture: the M4F handles primary application logic and motor control with single-cycle multiply and FPU, while the M0+ manages peripheral offload, security services, and real-time I/O handling via hardware inter-processor communication. Its memory subsystem includes SECDED ECC on all safety-critical SRAM and flash, and supports Firmware Over-The-Air (FOTA) via dual-bank flash with RWW capability.

It integrates three DMA controllers (P-DMA0: 92 channels, P-DMA1: 44 channels, M-DMA0: 4 channels), six TCPWM blocks per timer group, synchronized SAR ADC sampling across three 12-bit converters (up to 1 Msps), and five Smart I/O blocks enabling Boolean logic at the GPIO level-enabling deterministic low-latency signal conditioning without CPU intervention.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of each CPU core in CYT2B94CACQ0AZEGST?

The Arm® Cortex®-M4F core operates at up to 160 MHz, delivering 200 DMIPS performance with single-cycle multiply and hardware FPU. The Arm® Cortex®-M0+ core runs at up to 100 MHz, optimized for deterministic peripheral handling and security services. Both cores are independently clocked and can operate simultaneously without contention.

Does CYT2B94CACQ0AZEGST support Over-The-Air (OTA) firmware updates?

Yes. It supports secure OTA updates via its dual-bank flash architecture with Read-While-Write capability. The crypto engine validates digital signatures using ECDSA or RSA before bank swap, and the M0+ core handles update orchestration while the M4F continues real-time CAN FD messaging-ensuring zero downtime during field updates.

Which communication protocols does CYT2B94CACQ0AZEGST natively support without external transceivers?

CYT2B94CACQ0AZEGST integrates native PHY-level support for CAN FD (8 channels), LIN (12 channels), and CXPI (4 channels) with internal drivers, slew-rate control, and fault detection. No external transceivers are needed for basic bus operation-though external CAN FD transceivers are required for full ISO 11898-2 physical layer compliance.

How many analog-to-digital converter (ADC) channels are available, and what is their resolution and sampling rate?

It features three independent 12-bit SAR ADCs: ADC0 (24 logical + 1 physical), ADC1 (32 logical + 1 physical), ADC2 (8 logical + 1 physical), totaling 67 external channels. Each ADC achieves up to 1 Msps sampling rate, with synchronized start capability across all three for simultaneous motor current acquisition.
