Product details
Overview
CY9BF517TBGL-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, 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 real-time embedded motor control systems.
For engineers reviewing the CY9BF517TBGL-GK7E1 datasheet, CY9BF517TBGL-GK7E1 pinout, CY9BF517TBGL-GK7E1 application, or CY9BF517TBGL-GK7E1 equivalent, key selection criteria include dual CAN timing compliance, USB host/device coexistence, Flash accelerator performance at >72 MHz, and 154 fast I/O pins in 176-pin LQFP package.
Technical Context
This MCU implements the ARM Cortex-M3 r2p1 core with Memory Protection Unit (MPU), NVIC supporting 48 peripheral interrupts across 16 priority levels, and SysTick timer for RTOS integration. Its dual CAN controllers each support 1 Mbps and 32 message buffers, enabling robust automotive and industrial network nodes.
The peripheral set includes three independent A/D converters (12-bit, 1.0 µs conversion @5 V), eight-channel DMA with burst/block/demand transfer modes, and dedicated motor control blocks: QPRC (3 channels, 16-bit position/revolution counters), multi-function timers with dead-time insertion and DTIF interrupt, and base timers configurable as PWM/PPG/reload/PWC units.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F303VET6 | ARM Cortex-M4F core, 72 MHz, 512 KB Flash, no built-in CAN FD, single CAN 2.0B, no QPRC | Lacks quadrature encoder hardware; relies on GPIO + timer for position counting - increases CPU load and limits resolution. | Prefer when floating-point math or DSP extensions are required, but not for high-channel-count motor position capture. |
| R7F7010233AFP | Renesas RH850/F1L core, 64 MHz, 768 KB Flash, dual CAN, QPRC, but no USB host capability | Supports CAN FD and higher functional safety ASIL-B features, but lacks USB host - cannot serve as firmware update gateway. | Prefer for automotive ECU designs requiring ISO 26262 compliance, but not where USB host is mandatory. |
Compared with STM32F303VET6 and R7F7010233AFP, CY9BF517TBGL-GK7E1 uniquely combines dual CAN 2.0B, USB device+host, QPRC, and 144 MHz Cortex-M3 in a single 176-pin LQFP - making it optimal for cost-sensitive, space-constrained motor gateways needing both fieldbus and service connectivity.

FAQ
What is the maximum operating frequency and how is it achieved?
The CY9BF517TBGL-GK7E1 achieves up to 144 MHz using the Main PLL with either an external 4–48 MHz crystal or the 4 MHz internal high-speed CR oscillator as input. The Flash Accelerator enables zero-wait-state execution at ≤72 MHz and maintains effective bandwidth above that via prefetch and trace buffer - confirmed in Section 12.4.4 of datasheet 002-05602 Rev. *D.
Does this MCU support CAN FD or only classical CAN?
This MCU supports only Classical CAN (ISO 11898-1, CAN 2.0A/B) at up to 1 Mbps per channel. It does not implement CAN FD features such as flexible data-rate or extended data length. The dual CAN controllers each provide 32 message buffers and full mailbox arbitration, as specified in Section 3.4 of the FM3 Peripheral Manual.
How many independent A/D converters are integrated and what is their resolution?
The CY9BF517TBGL-GK7E1 integrates three independent 12-bit successive approximation register (SAR) A/D converters. Each supports 1.0 µs conversion time at 5 V supply, with configurable priority levels, scanning mode, and dedicated FIFOs (16-step for scan, 4-step for priority). This is documented in Section 3.10 of the datasheet.
Is USB host functionality supported, and what are its limitations?
Yes, USB host functionality is fully supported on Channel 1, including automatic device connect/disconnect detection, IN/OUT token handshake, and up to 256-byte packet length. It supports Bulk, Interrupt, and Isochronous transfers but does not support USB OTG or high-speed (480 Mbps) operation - limited to Full-Speed (12 Mbps) and Low-Speed (1.5 Mbps) per Section 3.5 of the datasheet.
