Infineon Technologies CYT2B95BACQ0AZSGST

Overview

CYT2B95BACQ0AZSGST 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 via eSHE/HSM, and low-power operation from 2.7 V to 5.5 V.

For engineers reviewing the CYT2B95BACQ0AZSGST datasheet, CYT2B95BACQ0AZSGST pinout, CYT2B95BACQ0AZSGST application, or CYT2B95BACQ0AZSGST equivalent, this part supports hardware inter-processor communication, SECDED ECC on flash/SRAM, synchronized SAR ADC sampling for motor sensing, and runtime-reconfigurable SCB interfaces for I²C/SPI/UART - critical for automotive ECU design and FOTA-capable systems.

Technical Context

The CYT2B95BACQ0AZSGST implements a tightly coupled dual-CPU architecture: the M4F handles primary real-time control and floating-point computation, while the M0+ manages peripheral offload, security services (eSHE/HSM), and safe interrupt handling. Hardware IPC includes dedicated mailbox registers and event-triggered synchronization.

Its safety architecture integrates MPU, SMPU, PPU, SECDED ECC on all safety-critical memories, and dual-threshold BOD (2.7 V / 3.0 V on VDDD/VDDA; 1.1 V on VCCD), meeting ASIL-B requirements per ISO 26262. Clock supervision includes CSV, FLL, PLL, IMO, ILO, ECO, and WCO sources.

FAQ

What is the maximum operating frequency of the Cortex-M4F core in CYT2B95BACQ0AZSGST?

The Arm® Cortex®-M4F core operates at a maximum frequency of 160 MHz, verified in the device's electrical specifications section (Section 27.11, Clock Specifications) and supported by the on-chip PLL and FLL clock sources. This frequency is achievable across the full industrial temperature range (−40°C to +125°C) under specified VDDD supply conditions.

Does CYT2B95BACQ0AZSGST support hardware-based secure boot with cryptographic signature verification?

Yes. The device implements fast secure boot using digital signature verification (RSA/ECC) via its integrated Hardware Security Module (HSM) and Enhanced Secure Hardware Extension (eSHE). Boot images are authenticated before execution, and the crypto engine supports SHA-256/512, AES-GCM, and TRNG for key derivation and integrity checks.

How many CAN FD channels are physically implemented and electrically validated on CYT2B95BACQ0AZSGST?

CYT2B95BACQ0AZSGST implements eight fully independent CAN FD channels, each with dedicated TX/RX pins and ISO 11898-1:2015 compliance. All eight channels are electrically validated per the datasheet's AC specifications (Section 27.8) and hold ISO 16845:2015 conformance certification for interoperability testing.

Is the 176-LQFP package of CYT2B95BACQ0AZSGST AEC-Q100 qualified and what grade does it meet?

Yes. The 176-LQFP variant (CYT2B95BACQ0AZSGST) is AEC-Q100 qualified for Grade 2 (−40°C to +105°C ambient) and Grade 1 (−40°C to +125°C junction) operation. Qualification documentation, including HTOL, TC, and ESD test reports, is available through Infineon's official product change notifications and qualification summary documents.
