Product details
Overview
CY9BF518TBGL-GK7E1 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M3 microcontroller with 1 MB Flash, 128 KB SRAM, dual CAN 2.0B interfaces, USB 2.0 Full-Speed device/host support, and integrated motor control peripherals including QPRC, multi-function timers, and PWM generators. It operates up to 144 MHz, supports 2.7–5.5 V supply, and targets embedded motor control systems requiring real-time response and functional safety features.
For engineers reviewing the CY9BF518TBGL-GK7E1 datasheet, CY9BF518TBGL-GK7E1 pinout, CY9BF518TBGL-GK7E1 application, or CY9BF518TBGL-GK7E1 equivalent, this page delivers verified technical context, exact package mapping (LQFP-176), confirmed peripheral capabilities (dual CAN, USB host/device, 32-channel 12-bit ADC), and validated alternative options for industrial motor drive and automotive body control designs.
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. It integrates dual independent CAN controllers compliant with ISO 11898-1:2003, each supporting 1 Mbps data rate and 32 message buffers.
The on-chip peripheral set includes two USB 2.0 interfaces (one device-only, one host/device), eight configurable serial channels (UART/CSIO/LIN/I²C), three multi-function timers with A/D activation and dead-time insertion, and three Quadrature Position/Revolution Counters with 16-bit position/revolution counters and dual compare registers - all synchronized to a single clock domain for deterministic timing in closed-loop motor control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M3 r2p1, up to 144 MHz - enables deterministic real-time execution of complex motor FOC algorithms within sub-μs interrupt latency. |
| Flash Memory | 1 MB with Flash Accelerator - eliminates wait states up to 72 MHz; maintains equivalent performance beyond via trace buffer-assisted prefetching. |
| SRAM | 128 KB split into SRAM0 (64 KB, I/D bus) and SRAM1 (64 KB, system bus) - isolates instruction/data access from peripheral DMA transfers. |
| CAN Interfaces | 2 × CAN 2.0A/B, 1 Mbps max - supports dual-bus automotive body networks or redundant fieldbus links in industrial drives. |
| USB Interfaces | 2 × USB 2.0: ch.0 device-only (FS), ch.1 host/device (FS/LS) - enables firmware updates via USB device mode and peripheral attachment via host mode. |
| A/D Converter | 32-channel 12-bit SAR ADC, 1.0 μs conversion @ 5 V - provides fast sampling for current/voltage feedback in PMSM/BLDC motor control loops. |
| Power Supply | 2.7–5.5 V VCC, 3.0–3.6 V USBVCC - allows direct connection to 3.3 V or 5 V system rails while maintaining USB signal integrity. |
Pinout & Package
LQFP-176 package with 154 fast GPIOs, 5 V-tolerant pins on selected I/Os, and dedicated power/ground distribution optimized for EMI suppression in motor drive environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Core power supply and ground | Dedicated pairs per quadrant minimize IR drop and switching noise coupling into analog/peripheral domains. |
| USB0_DP / USB0_DM | USB 2.0 Full-Speed differential pair (device only) | Internally terminated; requires external 1.5 kΩ pull-up on DP for device enumeration - no external transceiver needed. |
| CAN0_TX / CAN0_RX | CAN controller output/input | CMOS-level signals; require external high-speed CAN transceiver (e.g., TJA1042) for bus compliance and fault protection. |
| QEA0 / QEB0 / QEI0 | Quadrature encoder A/B/Z inputs | Direct connection to incremental encoder outputs; support edge-triggered capture with programmable filter for noise immunity. |
| AD00–AD31 | Analog input channels | Share multiplexed pins with GPIO; internal 12-bit SAR converter supports scan/priority modes with FIFO buffering for continuous sampling. |
Key Features
| Feature | Design Value |
|---|---|
| Motor Control Timer Block | Three 16-/32-bit reload/PWM/PPG timers with dead-time insertion and DTIF emergency stop - enables precise gate drive timing for 3-phase inverter bridges. |
| Quadrature Position Counter | Three independent QPRC units with 16-bit position/revolution counters and dual compare registers - supports absolute position tracking and homing without external logic. |
| CRC Accelerator | Hardware CCITT CRC16 and IEEE-802.3 CRC32 engines - offloads checksum calculation from CPU during firmware OTA updates or CAN message validation. |
| Low-Power Modes | SLEEP, TIMER, STOP modes with wake-up via CAN, USB, QPRC, or external interrupt - extends battery life in portable motorized tools and sensors. |
| Debug Interface | Serial Wire JTAG Debug Port (SWJ-DP) with ETM trace - enables real-time instruction tracing and non-intrusive breakpoint debugging in live motor control loops. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F303RET6 | ARM Cortex-M4F core, 72 MHz max, 512 KB Flash, no native CAN FD, single CAN 2.0B, no QPRC | Lacks quadrature counter hardware and dual CAN - requires software-based position tracking and external CAN bridge for multi-bus topologies | Select when floating-point math acceleration is critical and motor position resolution can be handled externally. |
| R7F7016843AFP | Renesas RH850/U2A core, 120 MHz, 1.5 MB Flash, dual CAN FD, integrated CAN transceivers, no USB host | Includes CAN FD and built-in transceivers but omits USB host capability and SWJ-DP debug port | Select for automotive chassis networks requiring CAN FD bandwidth and reduced external component count, where USB connectivity is unnecessary. |

The CY9BF518TBGL-GK7E1 operates at up to 144 MHz using its main PLL and supports a wide VCC supply range of 2.7 V to 5.5 V. Its USB I/O rails (USBVCC0/USBVCC1) require 3.0–3.6 V when used for USB signaling, but default to 2.7–5.5 V when repurposed as GPIO - enabling flexible power architecture design across 3.3 V and 5 V systems.
Does CY9BF518TBGL-GK7E1 support USB host functionality, and which channels provide it?
Yes, CY9BF518TBGL-GK7E1 supports USB 2.0 Full-Speed and Low-Speed host functionality exclusively on channel 1 (USB1). Channel 0 (USB0) is device-only. The host interface supports bulk, interrupt, and isochronous transfers with automatic device connect/disconnect detection and up to 256-byte packet length - sufficient for HID, mass storage, and CDC-class peripherals.
How many CAN interfaces does CY9BF518TBGL-GK7E1 include, and what protocol versions are supported?
CY9BF518TBGL-GK7E1 integrates two independent CAN controllers compliant with ISO 11898-1:2003 (CAN Specification 2.0A/B). Each supports bit rates up to 1 Mbps, 32 configurable message buffers, and hardware acceptance filtering - enabling dual-bus architectures such as separate powertrain and body networks or redundant fieldbus links in industrial automation.
Is there hardware support for motor position sensing, and how is it implemented?
Yes, CY9BF518TBGL-GK7E1 includes three dedicated Quadrature Position/Revolution Counters (QPRC). Each accepts A/B/Z encoder signals, provides 16-bit position and revolution counters, and features two 16-bit compare registers for index pulse matching and limit detection - all implemented in hardware without CPU intervention, ensuring jitter-free position capture at encoder frequencies up to 10 MHz.
