Product details
Overview
CY9BF566MPMC1-G-JNE2 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 connected embedded systems requiring real-time processing and mixed-signal integration.
For engineers reviewing the CY9BF566MPMC1-G-JNE2 datasheet, CY9BF566MPMC1-G-JNE2 pinout, CY9BF566MPMC1-G-JNE2 application, or CY9BF566MPMC1-G-JNE2 equivalent, key selection criteria include its dual-CAN capability, 160 MHz Cortex-M4F core with MPU, integrated USB host/device stack, 12-bit ADC conversion time of 0.5 µs at 5 V, and support for deep-standby RTC with RAM retention.
Technical Context
This MCU implements a tightly coupled ARM Cortex-M4F core with hardware FPU and Memory Protection Unit (MPU), enabling deterministic real-time execution in safety-aware applications. Its dual CAN controllers each support 1 Mbps operation and 32 message buffers, with dedicated TX/RX FIFOs and automatic retransmission.
The peripheral subsystem integrates a DSTC (Descriptor-based System Transfer Controller) with 128 channels for CPU-offload data movement, alongside eight DMA channels and a CRC accelerator supporting CCITT CRC16 and IEEE-802.3 CRC32 - critical for firmware integrity verification and communication protocol compliance.
Key Specifications

Pinout & Package
CY9BF566MPMC1-G-JNE2 is housed in a 120-pin LQFP package (14 mm × 14 mm, 0.4 mm pitch) with exposed thermal pad. Pin functions are defined across five I/O ports (P0–P4), with configurable peripheral mapping via port relocate function. 5 V-tolerant pins are designated per Section 5 of the datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply / Ground | Dual power domains: VCC (2.7–5.5 V) for core/peripherals; USBVCC (3.0–3.6 V) required only when USB I/O active. |

|---|---|
|
Use Scenario: Closed-loop control of BLDC/PMSM motors in HVAC compressors or factory automation actuators. IC Role / Device Role / Timing Role: Real-time execution of FOC algorithms via Cortex-M4F+FPU, synchronized PWM generation, and current/voltage sensing via 24-channel ADC.

Use Scenario: Centralized control of lighting, windows, door locks, and climate in 12 V automotive platforms. IC Role / Device Role / Timing Role: Host controller managing LIN slave nodes (e.g., mirror controls), CAN messaging, and power sequencing with LVD2 auto-reset. Use Value: Dual CAN + LIN + UART peripherals eliminate external protocol translators; deep-standby RTC maintains time during ignition-off with <1 µA VBAT current. |
| Smart Grid Communication Gateway | Medical Pump Controller |
|
Use Scenario: Protocol gateway aggregating Modbus RTU (via UART), CANopen (via CAN), and USB host for field technician interface. IC Role / Device Role / Timing Role: USB host manages flash drive firmware updates; DSTC offloads serial-to-CAN packet translation without CPU intervention. Use Value: 128-channel DSTC enables zero-CPU packet forwarding between UART/CAN/USB; CRC32 accelerator validates firmware images before execution. |
Use Scenario: Precision infusion pump with flow rate monitoring, battery management, and alarm handling under IEC 62304 Class C requirements. IC Role / Device Role / Timing Role: Safety-critical runtime supervisor using MPU-enforced memory isolation, watchdog timers (hardware + software), and RTC-triggered maintenance alerts. Use Value: MPU prevents peripheral register corruption; dual watchdogs ensure fail-safe shutdown if either clock domain stalls; 32-byte backup registers retain calibration data during power loss. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32H743VI | Higher core frequency (480 MHz), dual-core (Cortex-M7/M4), no integrated CAN FD - lacks built-in USB host stack and QPRC encoder counter. | Better for AI-edge inference; less suited for cost-sensitive CAN-based motion control where QPRC simplifies encoder interface. | Choose when needing >300 MHz compute or dual-core RTOS partitioning; avoid if encoder position tracking or USB host firmware update is mandatory. |
| RA6M5G | Same Cortex-M4F core, 200 MHz max, 1 MB Flash, but only one CAN channel and no USB host - includes TrustZone security but no DSTC. | Stronger security certification path (PSA Level 3); weaker for multi-bus industrial gateways requiring simultaneous CAN/USB/LIN. | Prefer for secure boot and encrypted OTA updates; not recommended when dual CAN + USB host coexistence is required in same design. |
Compared with STM32H743VI and RA6M5G, CY9BF566MPMC1-G-JNE2 uniquely combines dual CAN 2.0B, USB host/device, QPRC, and DSTC in a single 120-pin LQFP - reducing BOM count and PCB area for compact industrial gateways and motor controllers.

FAQ
What is the maximum operating temperature range for CY9BF566MPMC1-G-JNE2?
The CY9BF566MPMC1-G-JNE2 is rated for industrial temperature range: –40 °C to +85 °C ambient. This is confirmed in Section 1.2 "Product Lineup" of datasheet 002-04864 Rev. *E, where the "-JNE2" suffix denotes the industrial grade with extended thermal qualification and 100% burn-in testing.
Does this MCU support CAN FD or only classical CAN 2.0?
CY9BF566MPMC1-G-JNE2 supports only CAN 2.0A/B (ISO 11898-1:2003), with bit rates up to 1 Mbps. It does not implement CAN FD frame format, arbitration bit rate switching, or flexible data field length. The datasheet explicitly lists "CAN Specification 2.0A/B" and specifies 32 message buffers per channel - consistent with classical CAN only.
Is USB host functionality available without external PHY hardware?
Yes - CY9BF566MPMC1-G-JNE2 integrates a full-speed USB 2.0 transceiver compliant with USB 2.0 specification. No external PHY is required for USB host or device operation; only passive termination (1.5 kΩ pull-up on DP for device mode) and proper layout per Section 13.3 "USB Layout Guidelines" are needed.
How is the 41-bit Unique ID accessed in firmware?
The 41-bit Unique ID is stored in dedicated read-only memory at address 0x0000_01FC (ID register). It can be read directly via 32-bit load instructions - the upper 9 bits reside in the upper half of the 64-bit register space. Datasheet Section 12.2 "Unique ID" confirms it is factory-programmed, non-erasable, and accessible without unlocking sequences.
