Infineon Technologies CY9BF218TPMC-GK7CGE1

Overview

CY9BF218TPMC-GK7CGE1 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-GK7CGE1 datasheet, CY9BF218TPMC-GK7CGE1 pinout, CY9BF218TPMC-GK7CGE1 application, or CY9BF218TPMC-GK7CGE1 equivalent, key selection criteria include Ethernet-MAC compliance with IEEE 802.3 and IEEE 1588-2008, dual USB host/device capability, 144 MHz real-time execution, hardware CRC acceleration, and low-power STOP/SLEEP/TIMER modes with wake-on-LAN and sub-clock watchdog support.

Technical Context

This MCU implements a deterministic real-time control architecture centered on the Arm Cortex-M3 r2p1 core with MPU and NVIC supporting 48 peripheral interrupts and 16 priority levels. Its memory subsystem integrates two independent SRAM banks (SRAM0 for I/D-code, SRAM1 for system bus) and a Flash accelerator enabling zero-wait-state access up to 72 MHz - critical for time-critical ISR latency.

The peripheral set is purpose-built for motion and networked control: Ethernet-MAC includes dedicated 2 KB TX/RX FIFOs and PTP timestamping; dual USB controllers support simultaneous device/host operation with auto-detect and 256-byte packet handling; and motor-specific blocks (QPRC, multi-function timer with DTIF, A/D activation compare) enable closed-loop position/speed regulation without external logic.

FAQ

What is the maximum operating frequency and how is it achieved?

The CY9BF218TPMC-GK7CGE1 achieves up to 144 MHz using its main PLL, which multiplies an external 4–50 MHz crystal or clock source. The Flash accelerator enables zero-wait-state execution up to 72 MHz; above that, the accelerator maintains equivalent performance by prefetching and buffering instructions, ensuring deterministic timing for real-time control loops.

Does this MCU support IEEE 1588 Precision Time Protocol (PTP)?

Yes - the integrated Ethernet-MAC fully complies with IEEE 1588-2008. It includes hardware timestamping for transmit and receive frames, dedicated PTP registers, and synchronization logic that operates independently of CPU load, enabling sub-microsecond time accuracy in industrial Ethernet networks like PROFINET IRT or TSN-aware systems.

Can the USB interfaces operate simultaneously as host and device?

Yes - USB Channel 0 operates as a Full-Speed device (up to 6 endpoints), while USB Channel 1 functions as a Full/Low-Speed host (supporting 256-byte packets and automatic device connect/disconnect detection). Both operate concurrently without resource conflict, enabling embedded USB host-peripheral bridging in a single chip.

What low-power modes are supported and what peripherals remain active?

Three low-power modes are supported: SLEEP (CPU halted, peripherals active), TIMER (CPU halted, RTC and watchdog running), and STOP (all clocks stopped except sub-clock domain). In STOP mode, the RTC, watchdog timer, external interrupt pins, and Ethernet wake-on-LAN remain functional - allowing wake-up from deep sleep via network event or timer expiry with full SRAM retention.
