Overview
CY9BF306NBPMC-G-UNE2 from Infineon is a 32-bit ARM Cortex-M3 microcontroller with 512 KB flash, 64 KB SRAM, operating at up to 100 MHz, and integrated CAN FD controller - used in automotive body control modules for real-time sensor data aggregation and actuator command execution.
For engineers reviewing the CY9BF306NBPMC-G-UNE2 datasheet, CY9BF306NBPMC-G-UNE2 pinout, CY9BF306NBPMC-G-UNE2 application, or CY9BF306NBPMC-G-UNE2 equivalent, key selection criteria include CAN FD compliance, ASIL-B capable safety features, flash ECC protection, and QFP100 package compatibility with automotive PCB layout constraints.
Technical Context
This MCU implements a dual-bank flash architecture supporting read-while-write operation and includes a hardware CRC engine for memory integrity verification. It integrates a 12-bit ADC with 24 channels and programmable sampling time, plus six 16-bit general-purpose timers with input capture and PWM output capability.
The device supports ISO 11898-1:2015 compliant CAN FD communication up to 5 Mbit/s with flexible data length (up to 64 bytes per frame) and includes dedicated message RAM with configurable FIFOs and mailbox filtering logic.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TC377TP-64F200N-DC | TriCore™ CPU, 200 MHz, no integrated CAN FD (requires external transceiver + protocol stack) | Targeted at powertrain ECUs requiring higher compute throughput but less focus on CAN FD bandwidth | Select when deterministic floating-point performance outweighs CAN FD native support. |
| S32K144HAT0MLHT | ARM Cortex-M4F, 112 MHz, 1 MB flash, single-bank flash architecture | Designed for entry-level automotive networking with basic CAN FD and no ASIL-B certified safety engine | Choose for cost-sensitive body electronics where OTA update concurrency is non-critical. |
Compared with TC377TP-64F200N-DC and S32K144HAT0MLHT, CY9BF306NBPMC-G-UNE2 uniquely delivers ASIL-B safety certification, dual-bank flash for concurrent OTA, and native CAN FD controller - making it optimal for mid-tier automotive body domain controllers requiring functional safety and field-upgradable firmware.
