Product details
Overview
CYT2CL8BAAQ0AZSGST from Infineon is a dual-core automotive microcontroller featuring an Arm® Cortex®-M4F CPU (160 MHz max) and Arm® Cortex®-M0+ CPU (100 MHz max), integrated CAN FD (up to 8 Mbps), LIN, CXPI, LCD controller, and hardware crypto engine supporting AES-256, ECC, SHA-512, and TRNG - deployed in entry-level automotive instrument clusters.
For engineers reviewing the CYT2CL8BAAQ0AZSGST datasheet, CYT2CL8BAAQ0AZSGST pinout, CYT2CL8BAAQ0AZSGST application, or CYT2CL8BAAQ0AZSGST equivalent, this MCU delivers ASIL-B functional safety, RWW flash for FOTA updates, 4160 KB code-flash + 512 KB SRAM, and dual-power-domain I/O with wakeup from Hibernate via up to four pins.
Technical Context
The CYT2CL8BAAQ0AZSGST implements a tightly coupled dual-CPU architecture: the M4F handles real-time cluster graphics and application logic, while the M0+ manages peripheral offload, secure boot, and safety monitoring via SMPU/PPU. Its clock system integrates IMO, ECO, WCO, PLL, FLL, and LPECO with CSV supervision.
It supports concurrent operation across power modes - Active, Sleep, DeepSleep, Hibernate - with SECDED ECC on all safety-critical memories, BOD at 2.7 V/3.0 V (VDDD/VDDA_ADC) and 1.1 V (VCCD), and hardware inter-processor communication enabling deterministic task partitioning between cores.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-core automotive MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32K344UAT0VLQY | Single-core Arm® Cortex®-M7 (320 MHz); no integrated LCD controller; includes Ethernet MAC | Targeted at gateway/routing roles requiring high-speed networking, not display-centric clusters | Select when Ethernet connectivity or higher single-thread performance outweighs LCD/cryptographic feature needs |
| TC377TP-64F200N | Tri-core (TriCore™ TC1.6P + 2x SCU); 200 MHz; no native CAN FD; requires external PHY for 100BASE-T1 | Designed for powertrain and chassis control with deterministic real-time scheduling, not infotainment interfaces | Select for ASIL-D powertrain applications where TriCore toolchain and lockstep execution are mandatory |
Compared with S32K344UAT0VLQY and TC377TP-64F200N, CYT2CL8BAAQ0AZSGST uniquely balances display interface capability, embedded crypto acceleration, and dual-core ASIL-B partitioning - making it optimal for cost-sensitive, graphics-enabled automotive clusters rather than pure networking or powertrain domains.
