Product details
Overview
CYT2B93BACQ0AZSGS from Infineon is a dual-core automotive microcontroller featuring a 160-MHz Arm® Cortex®-M4F CPU and a 100-MHz Arm® Cortex®-M0+ CPU, integrated 2112-KB code-flash with RWW support, 256-KB SRAM with retention control, and hardware crypto engine supporting AES-128/192/256, SHA-256/512, ECC, and TRNG - deployed in body control units requiring ASIL-B functional safety compliance.
For engineers reviewing the CYT2B93BACQ0AZSGS datasheet, CYT2B93BACQ0AZSGS pinout, CYT2B93BACQ0AZSGS application, or CYT2B93BACQ0AZSGS equivalent, key selection criteria include dual-CPU inter-processor communication, CAN FD (up to 8 channels, 8 Mbps), CXPI (4 channels), LIN (12 channels), and SECDED ECC on flash/SRAM for automotive ECU robustness.
Technical Context
The CYT2B93BACQ0AZSGS implements a heterogeneous dual-CPU architecture: the M4F handles real-time application processing with FPU and MPU, while the M0+ manages peripheral offload, security services (eSHE/HSM), and secure boot via digital signature verification. Hardware inter-processor communication uses dedicated mailbox and semaphore resources.
It integrates three DMA controllers (P-DMA0: 92 channels, P-DMA1: 44 channels, M-DMA0: 4 channels), supports firmware updates over-the-air via dual-bank flash, and delivers ASIL-B compliance through SMPU, PPU, watchdog supervision (MCWDT), and SECDED ECC on all safety-critical memories.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-core automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K344 | Single-core Arm® Cortex®-M7 (320 MHz); no M0+ co-processor; includes ASIL-D capable lockstep cores | Better suited for high-integrity powertrain or ADAS where lockstep redundancy is mandatory | Select when ASIL-D certification or higher compute throughput outweighs need for peripheral offload isolation |
| Renesas RH850/U2A | 32-bit RXv3 core (240 MHz); proprietary ISA; no Arm® architecture; integrated CAN FD and LIN but no CXPI | Strong legacy support in Japanese OEMs; limited toolchain flexibility vs. Arm® ecosystem | Prefer when migrating existing RH850-based platforms or requiring long-term supply continuity under Renesas' automotive roadmap |
Compared with NXP S32K344 and Renesas RH850/U2A, CYT2B93BACQ0AZSGS uniquely balances ASIL-B safety, Arm® ecosystem compatibility, CXPI integration, and hardware-isolated peripheral/security processing - making it optimal for cost-sensitive, feature-rich body electronics where dual-core task segregation adds value without ASIL-D overhead.
