Infineon Technologies CY9BF518TPMC-GK7E1

Overview

CY9BF518TPMC-GK7E1 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M3 microcontroller designed for motor control and industrial embedded systems. It operates up to 144 MHz, integrates 1 MB Flash and 128 KB SRAM (split into SRAM0/SRAM1), supports dual CAN 2.0A/B interfaces at 1 Mbps, and includes hardware-based motor control peripherals including QPRC, multi-function timers with dead-time insertion, and A/D converters with 1.0 μs conversion time at 5 V.

For engineers reviewing the CY9BF518TPMC-GK7E1 datasheet, CY9BF518TPMC-GK7E1 pinout, CY9BF518TPMC-GK7E1 application, or CY9BF518TPMC-GK7E1 equivalent, key selection criteria include its dual-CAN capability, 144 MHz real-time performance, integrated motor control timers with DTIF interrupt, USB 2.0 Full-Speed device/host support, and 32-channel 12-bit ADC with scanning FIFO - all in a 176-pin LQFP package.

Technical Context

The CY9BF518TPMC-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 combines five sources - main oscillator (4–48 MHz), sub-clock (32.768 kHz), high/low-speed internal CR oscillators, and Main PLL - enabling dynamic switching and robust clock supervision via CSV.

Peripheral architecture includes dual independent CAN controllers with 32 message buffers each, eight configurable serial interfaces (UART/CSIO/LIN/I²C), three multi-function timers with waveform generation and A/D activation triggers, and a dedicated Quadrature Position/Revolution Counter (QPRC) with 16-bit position/revolution counters and dual compare registers for encoder feedback in closed-loop motion control.

FAQ

What is the maximum operating frequency and supported voltage range for CY9BF518TPMC-GK7E1?

The CY9BF518TPMC-GK7E1 operates at up to 144 MHz and supports a wide VCC supply range of 2.7 V to 5.5 V. Its USB I/O voltage (USBVCC0/1) must be regulated between 3.0 V and 3.6 V when USB functionality is active, ensuring compliance with USB 2.0 Full-Speed signaling requirements and enabling interoperability with both 3.3 V and 5 V system domains.

Does CY9BF518TPMC-GK7E1 support hardware-based dead-time insertion for motor gate drivers?

Yes. The CY9BF518TPMC-GK7E1 includes dedicated motor control timers with configurable hardware dead-time insertion and a DTIF (Dead-Time Insertion Fault) interrupt. This feature automatically inserts non-overlapping delays between complementary PWM outputs and triggers an immediate interrupt on fault detection - eliminating software timing dependencies and enhancing inverter reliability in PMSM/BLDC applications.

How many CAN interfaces does CY9BF518TPMC-GK7E1 integrate, and what protocol versions are supported?

The CY9BF518TPMC-GK7E1 integrates two fully independent CAN controllers compliant with ISO 11898-1:2015 (CAN Specification 2.0A/B). Each supports bit rates up to 1 Mbps, features 32 message buffers with acceptance filtering, and operates autonomously with dedicated TX/RX pins - enabling dual-network architectures such as chassis CAN + powertrain CAN or redundant fieldbus topologies.

Is USB functionality available in both device and host modes on CY9BF518TPMC-GK7E1?

Yes. The CY9BF518TPMC-GK7E1 supports USB 2.0 Full-Speed (12 Mbps) in both device and host configurations. As a device, it supports up to 6 endpoints including control, bulk, interrupt, and isochronous transfers. As a host, it supports full-speed and low-speed devices, automatic connect/disconnect detection, and packet lengths up to 256 bytes - enabling firmware updates, diagnostics, and peripheral attachment without external USB controller ICs.
