Product details
Overview
CY9BF618SPMC-GK7E1 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M3 microcontroller optimized for motor control and industrial embedded applications. It operates at up to 144 MHz, integrates 1 MB Flash and 128 KB SRAM (64 KB SRAM0 + 64 KB SRAM1), and features dual Ethernet-MAC (10/100 Mbps), USB 2.0 Full-Speed device/host, and 32-channel 12-bit ADC with 1.0 μs conversion time.
For engineers reviewing the CY9BF618SPMC-GK7E1 datasheet, CY9BF618SPMC-GK7E1 pinout, CY9BF618SPMC-GK7E1 application, or CY9BF618SPMC-GK7E1 equivalent, key selection criteria include dual Ethernet support with MII/RMII PHY interface, motor-specific peripherals (QPRC ×3, multi-function timers ×3, DTIF interrupt), and industrial-grade power supply range (2.7–5.5 V).
Technical Context
This MCU implements the ARM Cortex-M3 r2p1 core with Memory Protection Unit (MPU) and NVIC supporting 48 peripheral interrupts across 16 priority levels. Its clock system includes five sources - main oscillator (4–50 MHz), sub-clock (32.768 kHz), high-speed/low-speed internal CR oscillators, and dual PLLs (main, USB/Ethernet) - enabling precise timing for real-time motor control and networked I/O.
The peripheral architecture is purpose-built for motion systems: three Quadrature Position/Revolution Counters (QPRC) directly interface rotary encoders; three multi-function timers provide PWM, dead-time insertion, A/D activation triggers, and DC chopper waveform generation; and dual Ethernet-MAC blocks support IEEE 802.3-compliant 10/100 Mbps operation with PTP (IEEE 1588-2008) timestamping and Wake-on-LAN.
Key Specifications

Key Features
| Feature | Design Value |
|---|---|
| Motor Control Timers ×3 | Each provides PWM, PPG, A/D activation, DTIF interrupt, and waveform generation - eliminates software overhead in field-oriented control (FOC) loops. |
| QPRC ×3 | Independent 16-bit position/revolution counters with configurable A/B/Z input edges - enables direct multi-axis encoder tracking without CPU intervention. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control and industrial connectivity applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32H743VI | ARM Cortex-M7 @ 480 MHz, single Ethernet-MAC, no native LIN or QPRC | Higher compute throughput but lacks integrated motor-specific peripherals (QPRC, DTIF, multi-function timers) | Select when AI-based predictive maintenance or complex HMI rendering is required; add external encoder interface IC if QPRC needed. |
| RZ/T2L R7S920012VCBG | ARM Cortex-R4 @ 800 MHz, dual Ethernet, TSN support, no USB host | Targeted for time-sensitive networking (TSN) in collaborative robots; lacks USB host and LIN | Select for deterministic multi-axis coordination over TSN; avoid if USB diagnostics or automotive LIN bus integration is mandatory. |
Compared with STM32H743VI and RZ/T2L, the CY9BF618SPMC-GK7E1 delivers superior out-of-box motor control capability through hardware QPRC, DTIF, and triple multi-function timers - reducing firmware development effort by ~30% for servo drive implementations while maintaining dual-Ethernet redundancy.

FAQ
What is the maximum operating frequency and supported voltage range?
The CY9BF618SPMC-GK7E1 operates at up to 144 MHz and supports a wide VCC supply range of 2.7 V to 5.5 V. USB I/O domains require 3.0–3.6 V (USBVCC0/1), and Ethernet I/O uses 3.0–5.5 V (ETHVCC). This flexibility allows direct interfacing with 3.3 V and 5 V peripherals without level shifters in many configurations.
Does this MCU support IEEE 1588 Precision Time Protocol (PTP)?
Yes - the dual Ethernet-MAC blocks include hardware timestamping compliant with IEEE 1588-2008 (PTP). Each MAC has dedicated registers to capture transmit/receive timestamps with nanosecond resolution, enabling sub-microsecond synchronization across distributed industrial nodes without external timing ICs.
How many quadrature encoder interfaces does it provide, and what are their capabilities?
The MCU integrates three independent Quadrature Position/Revolution Counters (QPRC). Each supports configurable edge detection on AIN/BIN/ZIN inputs, 16-bit position and revolution counters, and two 16-bit compare registers - allowing direct high-speed position capture from incremental encoders with zero CPU load and hardware index pulse handling.
Is USB host functionality available, and what transfer types does it support?
Yes - the MCU includes two USB 2.0 Full-Speed channels, each capable of device or host operation. In host mode, it supports Bulk, Interrupt, and Isochronous transfers, automatic device connect/disconnect detection, IN/OUT token handshake, and up to 256-byte packet length - enabling direct connection to USB HID devices, mass storage, or diagnostic tools without external USB host controllers.
