Infineon Technologies CYT2B93CACQ0AZEGST

Overview

CYT2B93CACQ0AZEGST 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, hardware crypto engine (AES-128/192/256, SHA-256/512, ECC, TRNG), and ASIL-B functional safety certification - deployed in body control modules requiring secure, real-time CAN FD, LIN, and CXPI communication.

For engineers reviewing the CYT2B93CACQ0AZEGST datasheet, CYT2B93CACQ0AZEGST pinout, CYT2B93CACQ0AZEGST application, or CYT2B93CACQ0AZEGST equivalent, this part supports FOTA-capable dual-bank flash, synchronized 12-bit SAR ADCs (up to 67 channels, 1 Msps), 152 GPIOs with wakeup capability, and hardware inter-processor communication - critical for automotive ECU design, secure boot validation, and low-power sleep mode sequencing.

Technical Context

The CYT2B93CACQ0AZEGST implements a tightly coupled dual-CPU architecture: the M4F handles primary application logic and signal processing with single-cycle multiply and FPU, while the M0+ manages peripheral offload, security services (eSHE/HSM), and real-time response via hardware IPC. Memory subsystem includes SECDED ECC on SRAM and flash, MPU/SMPU enforcement, and PPU-protected peripherals.

Its timing system integrates IMO, ILO, ECO, WCO, PLL, and FLL sources; communication stack delivers eight CAN FD channels (ISO 11898-1:2015 compliant, up to 8 Mbps), twelve LIN (ISO 17987), and four CXPI interfaces - all runtime-reconfigurable via SCB blocks. Power management supports Hibernate, DeepSleep, and five configurable low-power modes with multi-threshold BOD.

FAQ

What is the maximum operating frequency of the Cortex-M4F core in CYT2B93CACQ0AZEGST?

The Arm® Cortex®-M4F core operates at up to 160 MHz, confirmed in the device's electrical specifications (Section 27.2) and clock diagram (Section 8). This frequency is achievable under full voltage (5.5 V) and temperature (125°C) conditions with PLL configuration, and is sustained across all supported operating modes except Hibernate.

Does CYT2B93CACQ0AZEGST support true hardware-based secure boot?

Yes - it implements fast secure boot using digital signature verification (ECDSA with P-256 curve) and AES-GCM decryption of signed firmware images. The hardware crypto engine performs signature validation and image decryption before execution, with root-of-trust anchored in immutable ROM bootloader and eSHE-managed keys.

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

The CYT2B93CACQ0AZEGST (176-LQFP package) supports all eight CAN FD channels as specified in Table 1-1 of the datasheet. Pin assignments for CANFD0–CANFD7 are fully allocated in the 176-pin LQFP layout (Sections 10 and 12), with dedicated TX/RX pairs routed to separate I/O banks for noise isolation.

Is the 12-bit SAR ADC capable of simultaneous sampling across all three converters?

Yes - the device supports hardware-synchronized sampling across ADC0, ADC1, and ADC2 using a common trigger source (e.g., TCPWM or EVTGEN). This is explicitly documented in Section 4.4.3 and verified in the ADC register map (ADCPWR_CTL.SYNC_EN), enabling phase-aligned current/voltage capture for motor control.
