Infineon Technologies CYT2B94CACQ0AZSGST

Overview

CYT2B94CACQ0AZSGST 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.

For engineers reviewing the CYT2B94CACQ0AZSGST datasheet, CYT2B94CACQ0AZSGST pinout, CYT2B94CACQ0AZSGST application, or CYT2B94CACQ0AZSGST equivalent, key selection criteria include dual-CPU inter-processor communication, eSHE/HSM crypto engine support (AES-128/192/256, SHA-256/512, ECC), SECDED ECC on flash/SRAM, and 152 GPIO wakeup capability across Sleep/DeepSleep/Hibernate modes.

Technical Context

The CYT2B94CACQ0AZSGST implements a tightly coupled dual-CPU subsystem where the M4F handles primary application processing and the M0+ manages peripheral offload and security services-including secure boot via digital signature verification and fast boot execution. Hardware inter-processor communication enables deterministic message passing without software arbitration.

It integrates three DMA controllers (P-DMA0: 92 channels, P-DMA1: 44 channels, M-DMA0: 4 channels), supports synchronized sampling across three 12-bit SAR ADCs (up to 1 Msps each), and delivers ASIL-B compliance through MPU, SMPU, PPU, SECDED ECC on all safety-critical memories, and dual-threshold BOD (2.7 V / 3.0 V on VDDD/VDDA).

FAQ

What is the maximum operating temperature range for CYT2B94CACQ0AZSGST?

The CYT2B94CACQ0AZSGST is qualified per AEC-Q100 Grade 2, supporting continuous operation from –40°C to +125°C ambient temperature. This rating applies to the full 176-LQFP package variant and is validated across voltage (2.7–5.5 V) and frequency (160 MHz M4F / 100 MHz M0+) specifications per Infineon's datasheet Rev. *I, Section 27.2.

Does CYT2B94CACQ0AZSGST support hardware-based secure boot with public-key verification?

Yes. The device implements secure boot using the integrated crypto engine to perform ECDSA signature verification against SHA-256 hashes of firmware images stored in code-flash. Public keys are provisioned in one-time-programmable (OTP) memory, and boot validation occurs before M4F execution begins-ensuring immutable root-of-trust.

How many CAN FD channels are physically implemented in this specific part number?

CYT2B94CACQ0AZSGST implements eight fully independent CAN FD controller instances (TTCAN0–TTCAN7), each with dedicated TX/RX pins and configurable bit rates up to 8 Mbps. All eight channels operate concurrently and support ISO 11898-1:2015 and Bosch CAN FD v1.0 frame formats, as confirmed in the peripheral instance list (Table 1-1, Datasheet p.6).

Is the 256-KB SRAM partitioned with retention control per block?

Yes. The 256-KB SRAM is divided into multiple retention domains, allowing selective retention of specific memory regions during DeepSleep and Hibernate modes. Retention granularity is configurable per 4-KB block via the Power Management Unit (PMU), enabling precise trade-offs between wakeup latency and current consumption.
