Product details
Overview
CY9BF566RBGL-GK7E1 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M4F microcontroller with FPU, 1024 KB MainFlash, 64 KB SRAM0, dual CAN 2.0B interfaces, USB 2.0 Full-Speed device/host, and 24-channel 12-bit ADC. It operates up to 160 MHz and supports motor control, industrial automation, and embedded connectivity applications.
For engineers reviewing the CY9BF566RBGL-GK7E1 datasheet, CY9BF566RBGL-GK7E1 pinout, CY9BF566RBGL-GK7E1 application, or CY9BF566RBGL-GK7E1 equivalent, key selection criteria include real-time motor control capability, dual CAN + USB coexistence, Flash accelerator performance at >72 MHz, and deep-sleep RTC retention with VBAT support.
Technical Context
This MCU integrates an ARM Cortex-M4F core (r0p1 revision) with hardware FPU and MPU for deterministic real-time execution in safety-aware systems. Its dual CAN controllers operate at up to 1 Mbps with 32 message buffers each, and USB supports simultaneous device/host roles with endpoint double buffering and automatic connect/disconnect detection.
The peripheral set includes eight multi-function serial channels (UART/CSIO/LIN/I²C), DSTC with 128 descriptor-based DMA channels, and dedicated motor control timers with dead-time insertion, A/D activation triggers, and quadrature encoder inputs - all synchronized to a single clock domain with dynamic frequency scaling from 2.7 V to 5.5 V supply.

Applications
| Industrial Motor Drive | Automotive Body Control Module |
|---|---|
|
Use Scenario: Closed-loop PMSM/BLDC motor control with field-oriented control (FOC) and current sensing. IC Role / Device Role / Timing Role: Real-time execution of FOC algorithm, PWM generation with dead-time, ADC-triggered current sampling, and CAN feedback reporting. Use Value: Hardware-accelerated motor timers and synchronized A/D activation eliminate software jitter, enabling <1 µs timing precision for commutation. |
Use Scenario: Centralized vehicle body electronics managing door locks, lighting, window lift, and LIN-connected sensors. IC Role / Device Role / Timing Role: CAN gateway between powertrain and body networks; LIN master for seat/mirror modules; USB for firmware updates. Use Value: Dual CAN ports isolate diagnostic and control traffic; integrated LIN 2.1 reduces external transceiver count; USB host enables field reprogramming. |
| Smart Grid Communication Node | Medical Pump Controller |
|
Use Scenario: Substation RTU with protocol translation between Modbus TCP (Ethernet via external PHY) and legacy fieldbus (CAN/LIN). IC Role / Device Role / Timing Role: Protocol stack processor with CAN/LIN peripherals, USB for configuration, and RTC for time-stamped event logging. Use Value: VBAT-backed RTC retains calendar across power loss; deep-standby modes extend battery life during idle periods without losing time accuracy. |
Use Scenario: Precision infusion pump requiring safety-critical flow rate control, fault monitoring, and human-interface communication. IC Role / Device Role / Timing Role: Safety-monitored motor driver with watchdog timers (hardware + software), analog front-end for pressure/flow sensing, and USB diagnostics. Use Value: Dual watchdog architecture ensures fail-safe shutdown: hardware WDT runs on low-speed CR clock during STOP mode; software WDT validates application health. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit ARM Cortex-M4F microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32H743VI | Higher core speed (480 MHz), dual-core option, no integrated USB host; lacks built-in CAN FD support | Better for compute-intensive HMI or AI edge inference; less suitable for dual-CAN+USB coexistence in compact designs | Choose when floating-point throughput >160 MHz is required and CAN FD is not needed |
| RA6M5GFP | Same 200 MHz Cortex-M33 core, TrustZone security, no USB host; includes Ethernet MAC but no SD card interface | Stronger for secure OTA updates and networked industrial gateways; missing USB host limits local firmware update flexibility | Prefer for applications requiring PSA-certified security and Ethernet connectivity over USB host |
Compared with STM32H743VI and RA6M5GFP, CY9BF566RBGL-GK7E1 uniquely balances dual CAN 2.0B, USB device/host, and motor-control peripherals in a single 120-pin LQFP - making it optimal for space-constrained, real-time embedded systems needing mixed-protocol connectivity without external bridge ICs.

The CY9BF566RBGL-GK7E1 operates at up to 160 MHz with a supply voltage range of 2.7 V to 5.5 V on VCC. USB I/O requires 3.0–3.6 V on USBVCC when active, while VBAT supports the same 2.7–5.5 V range for RTC backup. All specifications are validated across this full voltage and temperature range per the official Infineon datasheet Rev. *E.
Does CY9BF566RBGL-GK7E1 support USB host functionality without external PHY?
Yes - CY9BF566RBGL-GK7E1 integrates a full USB 2.0 Full-Speed host controller with built-in transceiver, supporting Low-Speed and Full-Speed devices directly. It handles IN/OUT token handshaking, automatic device detection, and up to 256-byte packet transfers without requiring an external PHY chip.
How many CAN interfaces does CY9BF566RBGL-GK7E1 support, and what protocol versions are implemented?
CY9BF566RBGL-GK7E1 supports two independent CAN controllers compliant with ISO 11898-1:2015 (CAN Specification 2.0A/B). Each controller supports bit rates up to 1 Mbps, 32 message buffers, and hardware filtering - confirmed in Section 12.3 of the Infineon datasheet 002-04864 Rev. *E.
Is the Flash memory protected against unauthorized read or modification?
Yes - both MainFlash and WorkFlash include hardware-based code protection features. These include flash lock bits, region-based write/read protection, and security functions shared between memories. Protection settings persist across resets and are configured via dedicated system registers documented in the "Security Functions" section of the datasheet.
