Product details
Overview
CY9BF467RBGL-GK7E1 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M4F microcontroller with 1024 KB Flash, 128 KB SRAM (64+32+32), dual CAN 2.0B interfaces, 24-channel 12-bit ADC, and operation up to 160 MHz. It integrates motor control timers, SD card interface, RTC, QPRC, and hardware CRC accelerator for embedded motor drive and industrial automation systems.
For engineers reviewing the CY9BF467RBGL-GK7E1 datasheet, CY9BF467RBGL-GK7E1 pinout, CY9BF467RBGL-GK7E1 application, or CY9BF467RBGL-GK7E1 equivalent, key selection criteria include dual CAN support at 1 Mbps, 160 MHz real-time performance with FPU and MPU, 120-pin LQFP package with 5V-tolerant I/O, and integrated DSTC for zero-CPU-overhead peripheral data movement.
Technical Context
This MCU implements a full Arm v7-M architecture with DSP extensions and single-precision FPU, enabling deterministic motor control loop execution. Its memory subsystem includes two independent Flash banks (MainFlash + WorkFlash) with configurable wait states and built-in accelerator for zero-wait access up to 72 MHz.
The peripheral set targets real-time industrial edge nodes: dual CAN controllers with 32 message buffers each, 8-channel DMA plus 128-channel DSTC for autonomous data routing, and dedicated multi-function timers with dead-time insertion and A/D trigger synchronization for three-phase inverter control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RA6M5GFP120A | 240 MHz Cortex-M33, 1 MB Flash, no integrated CAN FD, single CAN 2.0B | Lacks dual CAN and QPRC; adds TrustZone but requires external transceivers for CAN isolation | Preferred when higher CPU throughput and security are prioritized over dual-fieldbus redundancy |
| STM32H743VI | 480 MHz Cortex-M7, 2 MB Flash, dual CAN FD, no integrated SDIO or DSTC | Higher clock speed but lacks dedicated motor timer blocks and QPRC; SDIO requires software stack | Chosen for AI-edge inference workloads where floating-point performance outweighs motor control peripheral density |
Compared with RA6M5GFP120A and STM32H743VI, CY9BF467RBGL-GK7E1 delivers optimal balance of dual CAN 2.0B, QPRC, and DSTC for deterministic motor control-without requiring external logic or software overhead for encoder or fieldbus handling.

FAQ
What is the maximum operating frequency and does it require external clock conditioning?
The CY9BF467RBGL-GK7E1 operates at up to 160 MHz using its internal Main PLL, which accepts 4–48 MHz external crystal input. No external clock conditioning circuitry is required-the device includes integrated clock supervisors and fail-safe reset generation if the main oscillator stops or deviates beyond ±20% tolerance.
Does this MCU support CAN FD or only classical CAN 2.0?
This device supports CAN 2.0A/B only, with two fully independent controllers compliant to ISO 11898-1:2003. It does not implement CAN FD protocol features such as flexible data-rate or extended data length. Each controller supports bit rates up to 1 Mbps and includes 32 dedicated message buffers with hardware acceptance filtering.
How is flash security implemented and can it prevent unauthorized firmware extraction?
Flash protection uses hardware-enforced code read-out disable and region locking via dedicated security registers. Once enabled, debug access (SWJ-DP) and external read attempts return dummy data. The WorkFlash and MainFlash share the same security mechanism, and protection persists across power cycles-meeting IEC 62443-3-3 SL2 requirements for embedded firmware confidentiality.
What low-power modes are available and what peripherals remain active in STOP mode?
Six low-power modes are supported: SLEEP, TIMER, RTC, STOP, Deep Standby RTC, and Deep Standby STOP. In STOP mode, the CPU, Flash, and most clocks halt-but the sub-clock (32.768 kHz) remains active, allowing RTC, WDT, and external interrupt wake-up. VBAT-supplied circuits (RTC, backup registers, 32 kHz oscillator) retain state even when main VCC is removed.
