Infineon Technologies CY9BF218TPMC-GK7E1

Overview

CY9BF218TPMC-GK7E1 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 1 MB Flash, 128 KB SRAM, integrated Ethernet-MAC, dual USB 2.0 Full-Speed interfaces, and motor control peripherals including QPRC, multi-function timers, and 32-channel 12-bit ADC. It operates up to 144 MHz, supports 2.7–5.5 V supply, and targets real-time embedded control in industrial automation and motor drive systems.

For engineers reviewing the CY9BF218TPMC-GK7E1 datasheet, CY9BF218TPMC-GK7E1 pinout, CY9BF218TPMC-GK7E1 application, or CY9BF218TPMC-GK7E1 equivalent, key selection criteria include Ethernet-MAC compliance with IEEE 802.3, dual USB device/host capability, 144 MHz Cortex-M3 performance, flash accelerator for zero-wait-state access at 72 MHz, and integrated motor control timing functions (QPRC, PPG, DTIF).

Technical Context

The CY9BF218TPMC-GK7E1 implements an Arm Cortex-M3 r2p1 core with MPU and NVIC supporting 48 peripheral interrupts and 16 priority levels. It integrates dual USB controllers (one device/host capable, one device-only), a single IEEE 802.3-compliant Ethernet-MAC with MII/RMII PHY interface, and dedicated hardware accelerators for CRC16/32 and trace buffering.

Its peripheral set includes three multi-function timers with waveform generation and dead-time insertion, three QPRC units for encoder position tracking, eight DMA channels with independent bus access, and a 32-channel 12-bit SAR ADC with 1.0 µs conversion time at 5 V and dual FIFO modes for scan/priority sequencing.

FAQ

What power supply configurations does CY9BF218TPMC-GK7E1 require?

The device requires four independent supplies: VCC (2.7–5.5 V for core/logic), USBVCC0/1 (3.0–3.6 V when USB is active), and ETHVCC (3.0–5.5 V for Ethernet PHY interface). Each domain must be decoupled locally with 100 nF ceramic capacitors; USB and Ethernet supplies may share a 3.3 V rail if current limits permit.

Does CY9BF218TPMC-GK7E1 support IEEE 1588 Precision Time Protocol?

Yes - its integrated Ethernet-MAC includes full IEEE 1588-2008 (PTP) hardware timestamping with nanosecond-resolution capture of sync, delay_req, and follow_up frames. Timestamp registers are accessible via memory-mapped registers and supported in Infineon's FM3 Ethernet driver library.

Can the USB interfaces operate simultaneously in host and device mode?

Yes - Channel 0 supports dual-role (host/device) operation, while Channel 1 is device-only. Both can be active concurrently: e.g., CY9BF218TPMC-GK7E1 acts as USB device to a PC while hosting a USB HID keyboard or flash drive on Channel 0, using separate endpoints and DMA channels.

How is motor emergency stop implemented without CPU involvement?

Via the dedicated DTIF (Dead-Time Insertion Fault) input pin: asserting this pin triggers immediate forced shutdown of all PWM outputs within <1 µs, independent of CPU state or interrupt latency. The event also generates an NMI to log fault context before entering safe state.
