Product details
Overview
CY9BF566RPMC-GNE2 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, supports motor control timers, SD card interface, and real-time clock - deployed in industrial motor drives and automotive body control modules.
For engineers reviewing the CY9BF566RPMC-GNE2 datasheet, CY9BF566RPMC-GNE2 pinout, CY9BF566RPMC-GNE2 application, or CY9BF566RPMC-GNE2 equivalent, key selection criteria include Flash/SRAM partitioning, dual CAN timing tolerance, USB host/device coexistence, RTC+VBAT retention capability, and 5 V-tolerant GPIO allocation per pin function mapping.
Technical Context
The CY9BF566RPMC-GNE2 implements a tightly coupled ARM Cortex-M4F core (r0p1) with integrated MPU, NVIC (128 peripheral interrupts), SysTick, and DSP extensions - enabling deterministic real-time execution in safety-critical embedded control. Its memory subsystem features two independent Flash banks (MainFlash + 32 KB WorkFlash) and three SRAM blocks (SRAM0–SRAM2) with distinct bus affiliations for concurrent instruction/data access.
Peripheral integration includes a descriptor-based DSTC (128 channels) for CPU-offloaded data movement, dual CAN controllers with 32 message buffers each, and a multi-function serial interface supporting UART/CSIO/LIN/I²C on eight channels - all synchronized via a dynamic clock system with five selectable sources and CSV-based external oscillator supervision.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | ARM Cortex-M4F (r0p1) with FPU and DSP instructions - enables floating-point math and signal processing without software emulation. |
| Max Clock Frequency | 160 MHz - supports high-speed motor control loop execution and real-time USB packet handling. |
| MainFlash Memory | 1024 KB with Flash Accelerator - zero-wait-state access ≤72 MHz; maintains performance at full 160 MHz via accelerator. |
| SRAM Configuration | SRAM0 (64 KB, I/D-code bus), SRAM1 (32 KB), SRAM2 (32 KB) - enables cacheless deterministic memory partitioning for RTOS tasks and DMA buffers. |
| CAN Interfaces | Two independent CAN 2.0A/B controllers, 1 Mbps max - supports dual-bus vehicle networks or redundant industrial fieldbus links. |
| USB Interface | Full-Speed device (6 endpoints, 256-byte EP1) + host (256-byte packets, auto-connect detection) - enables bidirectional peripheral attachment and firmware update over USB. |
| A/D Converter | Three 12-bit SAR ADCs, 0.5 μs conversion @5 V, 24 total channels - meets fast-sampling requirements for PMSM current sensing and analog sensor fusion. |
Pinout & Package
Package: 120-pin LQFP (14 mm × 14 mm, 0.4 mm pitch), RoHS-compliant, moisture sensitivity level 3. Pin functions mapped across four power domains (VCC, USBVCC, VBAT, AVCC) with 5 V-tolerant I/O on designated pins (e.g., P0_0–P0_7, P1_0–P1_7).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Core power supply / ground | Primary 2.7–5.5 V domain powering CPU, SRAM, and most peripherals; requires local decoupling per datasheet Section 6.1. |
| USBVCC / USBGND | USB I/O power / ground | 3.0–3.6 V supply dedicated to USB transceiver - must be isolated from main VCC to meet USB electrical compliance. |
| VBAT | Backup power input | Supplies RTC, 32 kHz oscillator, and 32-byte backup registers during main power loss - enables calendar continuity and wake-up from STOP mode. |
| XTAL / EXTAL | Main crystal oscillator inputs | Accepts 4–48 MHz parallel-resonant crystal; paired with internal PLL to generate 160 MHz system clock with ±0.5% stability under temperature variation. |
| RTC_XIN / RTC_XOUT | Real-time clock oscillator | Connects to 32.768 kHz tuning-fork crystal - provides timekeeping accuracy of ±20 ppm over –40°C to +85°C for calendar functions. |
| CAN0_TX / CAN0_RX | Channel 0 CAN differential signals | CMOS-level outputs/inputs compliant with ISO 11898-2; require external CAN transceiver (e.g., TJA1042) for bus coupling. |
| USB_DP / USB_DM | USB 2.0 Full-Speed differential pair | On-chip transceiver with integrated termination - connects directly to USB connector with 27 Ω series resistors per USB specification. |
Key Features
| Feature | Design Value |
|---|---|
| Dual CAN with 32 message buffers per channel | Enables concurrent reception/transmission on two independent buses without CPU polling - reduces interrupt load in automotive gateway applications. |
| Descriptor-based DSTC (128 channels) | Offloads memory-to-peripheral transfers (e.g., ADC→SRAM, UART→SDRAM) without CPU intervention - improves real-time determinism and throughput. |
| WorkFlash with configurable wait states | 32 KB Flash bank with adaptive wait-state logic (0–6 cycles) - allows safe code execution at any frequency from 40–160 MHz without recompilation. |
| Motor Control Timers with DTIF | Integrated dead-time insertion fault (DTIF) interrupt triggers immediate PWM shutdown on hardware fault - meets IEC 61800-5-2 functional safety requirements. |
| VBAT-powered RTC + 32-byte backup registers | Maintains calendar, alarm, and user state across full power cycles - eliminates need for external RTC IC or supercapacitor in battery-backed systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RA6M5 (R7FA6M5BH3CFP) | ARM Cortex-M33, 2MB Flash, 1MB SRAM, no built-in CAN FD; USB HS only (no host); single CAN 2.0B | Lacks dual CAN and USB host - unsuitable for automotive gateways requiring simultaneous CAN bus bridging and USB service port. | Select when higher security (TrustZone), larger memory, or Ethernet MAC is required - but verify CAN count and USB role compatibility. |
| S32K144 (S32K144HAT0MLHT) | ARM Cortex-M4F, 1MB Flash, 128KB SRAM, dual CAN FD, no USB host; includes ASIL-B safety documentation | Supports CAN FD (5 Mbps) but omits USB host and SD card interface - limits field-serviceability and local data logging capability. | Prefer for ASIL-B automotive applications where CAN FD bandwidth and safety certification outweigh USB/SD needs. |
Compared with RA6M5 and S32K144, the CY9BF566RPMC-GNE2 uniquely combines dual CAN 2.0B, USB device/host, SD card interface, and VBAT-retained RTC in a single 120-pin LQFP package - making it optimal for cost-sensitive, feature-rich embedded gateways requiring field-upgradability and battery-backed timekeeping.

FAQ
What is the maximum operating temperature range for CY9BF566RPMC-GNE2?
The CY9BF566RPMC-GNE2 is rated for industrial temperature operation from –40°C to +85°C ambient. This range is validated per JEDEC JESD22-A104 for thermal cycling and JESD22-A108 for high-temperature operating life. The RTC_XIN/RTC_XOUT circuit maintains ±20 ppm accuracy across this full range using a standard 32.768 kHz crystal.
Does CY9BF566RPMC-GNE2 support CAN FD or only classical CAN 2.0?
The CY9BF566RPMC-GNE2 supports only CAN 2.0A/B (ISO 11898-1:2003) at up to 1 Mbps - it does not implement CAN FD physical layer or protocol extensions. Each CAN controller has 32 message buffers with programmable acceptance filtering, but bit-rate switching, extended data length (up to 64 bytes), and flexible data-rate arbitration are not available.
How is USB device enumeration handled without external PHY?
The CY9BF566RPMC-GNE2 integrates a full-speed USB 2.0 transceiver with on-die termination and pull-up/pull-down resistors. Enumeration uses the internal USB_DP/USB_DM pins directly connected to the USB connector; no external PHY is needed. The device supports automatic descriptor handling for standard class requests (CDC, HID, MSC) via firmware libraries provided in the FM4 Peripheral Driver Library.
Can the WorkFlash memory be used for EEPROM emulation?
Yes - the 32 KB WorkFlash supports individual sector erase (4 KB sectors) and byte-programmable writes, making it suitable for EEPROM emulation. Cypress-provided middleware (FM4 Flash Library) includes wear-leveling and atomic write routines validated for ≥100,000 erase/write cycles. Data retention is guaranteed for 20 years at 85°C per JEDEC JESD22-A117.
