Infineon Technologies CY9BF617TBGL-GK7E1

Overview

CY9BF617TBGL-GK7E1 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M3 microcontroller in the FM3 family, designed for high-performance embedded motor control and industrial automation. It operates 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 at 5 V.

For engineers reviewing the CY9BF617TBGL-GK7E1 datasheet, CY9BF617TBGL-GK7E1 pinout, CY9BF617TBGL-GK7E1 application, or CY9BF617TBGL-GK7E1 equivalent, key selection criteria include dual Ethernet support with MII/RMII PHY interface, integrated motor control timers with dead-time insertion, USB host/device dual-role capability, and 5 V-tolerant GPIO on selected pins for industrial I/O interfacing.

Technical Context

The CY9BF617TBGL-GK7E1 implements an 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-two external oscillators (4–50 MHz main, 32.768 kHz sub), two internal CR oscillators (4 MHz high-speed, 100 kHz low-speed), and a configurable Main PLL-with independent CSV and LVD monitoring for robust operation in harsh environments.

Peripheral integration centers on deterministic real-time control: three multi-function timers with A/D activation compare and DTIF interrupt, three QPRC channels for encoder position tracking, and eight DMA channels with dedicated bus arbitration. The dual Ethernet-MAC supports IEEE 1588 PTP timestamping, while USB subsystem provides dual-channel full-speed operation with hardware endpoint buffering (up to 256-byte packets) and automatic device detection.

FAQ

What is the maximum operating frequency and supported voltage range for CY9BF617TBGL-GK7E1?

The CY9BF617TBGL-GK7E1 operates at up to 144 MHz and supports a wide VCC supply range of 2.7 V to 5.5 V. USB and Ethernet I/O rails require separate 3.0–3.6 V supplies when those interfaces are active, but revert to 2.7–5.5 V for general-purpose GPIO use. This flexibility allows direct interfacing with both 3.3 V and 5 V industrial sensors and actuators.

Does CY9BF617TBGL-GK7E1 support hardware-based functional safety features for motor control?

Yes. It includes dedicated hardware features for motor safety: DTIF (Dead-Time Insertion Fault) inputs trigger immediate PWM shutdown within one clock cycle, QPRC channels provide hardware encoder position tracking with 16-bit counters, and the MPU enforces memory partitioning between control and communication tasks. These features support design to IEC 61800-5-2 and ISO 13849 PLd requirements.

How many Ethernet and USB interfaces does CY9BF617TBGL-GK7E1 integrate, and what PHY interfaces are supported?

The device integrates two independent Ethernet-MACs supporting both MII (1 channel) and RMII (2 channels) PHY interfaces, plus dual USB 2.0 Full-Speed controllers with Device and Host capability. Each USB channel has dedicated DP/DM pins and hardware endpoint buffering, with automatic device connect/disconnect detection and token handshake handling-eliminating software overhead in enumeration and data transfer.

Can CY9BF617TBGL-GK7E1 operate with external memory, and what bus widths and address ranges are supported?

Yes. It features an External Bus Interface supporting SRAM, NOR, and NAND Flash with up to 8 chip selects, 8-/16-bit data width, and up to 25-bit addressing (256 MB total space). Address/data multiplexing and external RDY input are supported, enabling seamless expansion with off-chip program storage or high-speed data buffers in data-logging or HMI applications.
