Product details
Overview
CY9BF218SPMC-GK7CGE1 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 1 MB on-chip Flash, 128 KB SRAM, integrated Ethernet-MAC, dual USB 2.0 Full-Speed interfaces, and 32-channel 12-bit ADC. It operates up to 144 MHz, includes MPU, NVIC with 48 peripheral interrupts, and supports motor control via multi-function timers and QPRC. Used in industrial motor drives requiring real-time control, networked I/O, and deterministic communication.
For engineers reviewing the CY9BF218SPMC-GK7CGE1 datasheet, CY9BF218SPMC-GK7CGE1 pinout, CY9BF218SPMC-GK7CGE1 application, or CY9BF218SPMC-GK7CGE1 equivalent, key selection factors include Ethernet-MAC compliance with IEEE 802.3, dual USB device/host capability, 144 MHz Cortex-M3 performance, 2.7–5.5 V supply range, and FM3 family peripheral compatibility per Infineon's Peripheral Manual TYPE2 classification.
Technical Context
This MCU implements a full Arm Cortex-M3 r2p1 core with Memory Protection Unit (MPU), Nested Vectored Interrupt Controller (NVIC), and SysTick timer - enabling RTOS-based deterministic execution. It integrates dedicated hardware accelerators including CRC32/CCITT CRC16, Ethernet descriptor-based DMAC, and Flash Accelerator with 16 KB trace buffer for zero-wait-state access up to 72 MHz.
The peripheral set is structured around real-time industrial control: three multi-function timers support PWM, dead-time insertion, and A/D activation; three QPRC units interface directly with quadrature encoders; and the Ethernet-MAC includes MII/RMII PHY interface, Wake-on-LAN, and IEEE 1588 PTP timestamping - all accessible via dedicated DMA channels independent of CPU bus.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M3 r2p1, up to 144 MHz - enables hard real-time task scheduling with sub-1 µs interrupt latency. |
| Flash Memory | 1 MB with Flash Accelerator and 16 KB trace buffer - supports zero-wait-state execution at ≤72 MHz and deterministic code fetch above. |
| SRAM | 128 KB total (64 KB SRAM0 + 64 KB SRAM1), split across I-code/D-code and system buses - enables concurrent instruction fetch and DMA data movement. |
| Ethernet-MAC | IEEE 802.3-compliant 10/100 Mbps with MII/RMII, 2 KB TX/RX FIFO, and IEEE 1588 PTP support - delivers time-synchronized industrial networking without external PHY timing glue. |
| USB Interface | Dual USB 2.0 Full-Speed channels (device + host), each with configurable endpoints and 256-byte packet support - enables embedded host-side peripheral management and device-class connectivity. |
| A/D Converter | 32-channel 12-bit SAR ADC with 1.0 µs conversion @5 V and dual-mode FIFO (16-step scan / 4-step priority) - supports synchronized sampling across motor phase currents and analog sensors. |
| Timers & Counters | 16-channel base timer (PWM/PPG/reload), 3-unit multi-function timer (input capture/output compare/waveform gen), and 3-channel QPRC - provides complete encoder-based motion control stack in hardware. |
Pinout & Package
Package: 176-pin LQFP (24 × 24 mm, 0.4 mm pitch), RoHS-compliant, moisture sensitivity level 3. Pin mapping follows CY9B210T Series Pin Assignment (Document 002-04680 Rev. *F, pages 9–11), with dedicated power domains (VCC, USBVCC0/1, ETHVCC) and 154 GPIOs supporting port relocation and 5 V tolerance on selected pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Core power / ground | Primary 2.7–5.5 V supply domain for CPU, memory, and most peripherals; decoupling required per layout guidelines. |
| USBVCC0 / USBVCC1 | USB I/O power | 3.0–3.6 V supply for USB transceivers ch.0/ch.1; isolated from VCC to meet USB electrical compliance. |
| ETHVCC | Ethernet I/O power | 3.0–5.5 V supply for Ethernet PHY interface pins; supports both 3.3 V and 5 V PHY voltage levels. |
| XTAL / EXTAL | Main clock input | 4–50 MHz crystal oscillator connection for high-precision system timing and PLL reference. |
| OSC32K / OSC32KOUT | Sub-clock input/output | 32.768 kHz crystal connection for RTC, watchdog, and low-power mode timing. |
| MDIO / MDC | PHY management interface | IEEE 802.3-compliant MDIO/MDC signals for configuring external Ethernet PHY registers. |
| TXD0–TXD3 / RXD0–RXD3 | Ethernet MAC interface | MII/RMII data lanes; RMII uses 2-bit nibble-wide interface with REF_CLK, reducing pin count vs. full MII. |
Key Features
| Feature | Design Value |
|---|---|
| Flash Accelerator with 16 KB trace buffer | Enables zero-wait-state code execution up to 72 MHz and maintains deterministic performance at 144 MHz via prefetch and caching. |
| Dedicated Ethernet descriptor-based DMAC | Offloads frame transmission/reception handling from CPU, enabling concurrent application processing and network I/O without polling overhead. |
| Three Quadrature Position/Revolution Counters (QPRC) | Hardware-accelerated position tracking with 16-bit counters, ZIN-index capture, and dual compare registers - eliminates software encoder interpolation. |
| Motor Control Timer Block | Integrated dead-time insertion, DTIF emergency stop trigger, and A/D activation compare - enables safe, synchronized PWM generation and current sensing. |
| Port Relocation Function | Runtime remapping of peripheral functions (UART, I²C, CSIO, LIN) to alternate GPIO pins - increases PCB layout flexibility and reduces routing congestion. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32H743VI | Arm Cortex-M7 @ 480 MHz, dual-core option, no integrated Ethernet-MAC (requires external PHY + MAC logic), 2 MB Flash, 1 MB RAM | Lacks native Ethernet-MAC and QPRC; requires external PHY and software encoder counting; better for compute-intensive DSP tasks than deterministic motion control | Select when floating-point performance or AI inference acceleration outweighs need for hardware encoder/timer integration. |
| RA6M5LJ20A | Arm Cortex-M33 @ 200 MHz, 1 MB Flash, 384 KB RAM, integrated Ethernet-MAC (no PTP), 24-channel 12-bit ADC, no QPRC or motor-specific timers | Missing QPRC and dedicated motor control peripherals; Ethernet lacks IEEE 1588; higher clock but less deterministic real-time peripheral offload | Select for general-purpose industrial connectivity where PTP sync and encoder hardware are not required. |
Compared with STM32H743VI and RA6M5LJ20A, CY9BF218SPMC-GK7CGE1 offers unique hardware integration for motion control (QPRC, DTIF, A/D-triggered PWM) and time-critical networking (PTP-enabled Ethernet-MAC, dual USB host/device), making it optimal for cost-sensitive, single-chip motor+network edge nodes.

FAQ
What is the maximum operating frequency and supported clock sources?
The CY9BF218SPMC-GK7CGE1 operates up to 144 MHz using its Arm Cortex-M3 core. Supported clock sources include a 4–50 MHz external main oscillator, 32.768 kHz sub-clock, 4 MHz high-speed internal CR oscillator, 100 kHz low-speed internal CR oscillator, and a programmable Main PLL that can multiply any of these sources to achieve the target CPU frequency.
Does this MCU support IEEE 1588 Precision Time Protocol (PTP)?
Yes, the integrated Ethernet-MAC complies with IEEE 1588-2008 (PTP). It includes hardware timestamping for transmit and receive frames, enabling sub-microsecond time synchronization across industrial Ethernet networks without CPU intervention or external timestamping ICs.
How many USB interfaces does it have, and what modes are supported?
The device integrates two independent USB 2.0 Full-Speed interfaces. Channel 0 supports device-only mode with up to 6 endpoints (including double-buffered EP1–5); channel 1 supports both device and host modes, with automatic device connect/disconnect detection, IN/OUT token handshake, and 256-byte packet support in host mode.
Is there hardware support for motor control functions like dead-time insertion or emergency stop?
Yes. The multi-function timer block includes dedicated hardware for dead-time insertion between complementary PWM outputs and a DTIF (Dead-Time Insertion Fault) interrupt that triggers immediate PWM shutdown upon fault detection - critical for IGBT/MOSFET safety in motor inverters.
