Product details
Overview
CY9BF317TBGL-GK7E1 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M3 microcontroller with 1 MB Flash, 128 KB SRAM, USB 2.0 Full-Speed device/host interface, 32-channel 12-bit ADC (1.0 μs conversion), and motor control peripherals including QPRC, multi-function timers, and PWM. It operates at up to 144 MHz and supports industrial motor drives requiring real-time position sensing and dual USB connectivity.
For engineers reviewing the CY9BF317TBGL-GK7E1 datasheet, CY9BF317TBGL-GK7E1 pinout, CY9BF317TBGL-GK7E1 application, or CY9BF317TBGL-GK7E1 equivalent, key selection criteria include Flash/SRAM size, USB dual-role capability, 144 MHz Cortex-M3 performance, 32-channel ADC timing, and QPRC encoder interface support in 176-pin LQFP package.
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 USB controllers (one Full-Speed device + one Full/Low-Speed host), each with configurable endpoints and automatic connect/disconnect detection.
The peripheral set includes three independent 12-bit SAR ADC units with FIFO-based scanning, eight DMA channels with 32-bit addressing, and dedicated motor control blocks: Quadrature Position/Revolution Counter (QPRC) with 16-bit position/revolution counters and dual compare registers, plus multi-function timers with dead-time insertion and A/D activation triggers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | ARM Cortex-M3 r2p1, up to 144 MHz - enables deterministic real-time execution for motor control loops and USB protocol stacks. |
| Memory | 1 MB Flash + 128 KB SRAM (64 KB SRAM0 on I/D bus, 64 KB SRAM1 on system bus) - supports large firmware images and dual-bank buffering for USB and ADC data. |
| USB Interface | Dual USB: Full-Speed device (6 endpoints, double-buffered) + Full/Low-Speed host (256-byte packet, auto-detect) - enables embedded USB peripheral and host functionality in same device. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F407VGT6 | ARM Cortex-M4F core, 1 MB Flash, 192 KB SRAM, single USB OTG FS, no integrated QPRC | Lacks dedicated quadrature counter; requires GPIO + timer software emulation for encoder position | Prefer when floating-point math or audio processing is required; avoid if encoder resolution >16-bit or jitter-sensitive position capture needed. |

FAQ
What is the maximum operating frequency and supported voltage range?
CY9BF317TBGL-GK7E1 operates at up to 144 MHz with a core supply range of 2.7 V to 5.5 V. USB I/O domains (USBVCC0/1) require 3.0–3.6 V when active, while GPIO operation remains valid across the full VCC range. The internal CR oscillators provide clock redundancy down to 100 kHz for STOP-mode wake-up.
Does this MCU support USB device and host simultaneously?
Yes - it integrates two independent USB controllers: one Full-Speed device controller (up to 6 endpoints, double-buffered) and one Full/Low-Speed host controller (256-byte packet, auto-detect). They operate concurrently without resource conflict, enabling USB peripheral emulation and host-side HID/mass storage control in a single chip.
How does the QPRC block interface with incremental encoders?
The QPRC provides three independent channels, each with AIN/BIN/ZIN inputs configurable for rising/falling edge detection. Each channel includes a 16-bit position counter, 16-bit revolution counter, and two 16-bit compare registers. ZIN captures index pulses to reset revolution count, enabling absolute position tracking over multiple rotations without CPU intervention.
What debug and trace capabilities are built in?
It features Serial Wire JTAG Debug Port (SWJ-DP) and Embedded Trace Macrocell (ETM) supporting real-time instruction and data trace. The 16 KB on-chip trace buffer works with the Flash Accelerator to capture execution flow during high-speed motor control loops, enabling precise timing analysis and fault root-cause diagnosis without halting operation.
