Product details
Overview
CY9BF316TBGL-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 2.7–5.5 V supply for industrial motor drives and embedded controllers.
For engineers reviewing the CY9BF316TBGL-GK7E1 datasheet, CY9BF316TBGL-GK7E1 pinout, CY9BF316TBGL-GK7E1 application, or CY9BF316TBGL-GK7E1 equivalent, key selection criteria include Flash/SRAM size, USB dual-role capability, 144 MHz real-time performance, motor timing accuracy (QPRC + PWC), and 5 V-tolerant I/O 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-bus SRAM architecture (64 KB I/D-code SRAM0 + 64 KB system SRAM1) and Flash Accelerator enabling zero-wait-state access up to 72 MHz.
The peripheral set targets real-time motor control: three QPRC units for encoder position tracking, three multi-function timers with dead-time insertion and A/D activation compare, and LIN 2.1 + I²C + UART + CSIO serial interfaces-all configurable per channel. USB supports simultaneous device/host operation with 6 endpoints and automatic connect/disconnect detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | ARM Cortex-M3 r2p1, 144 MHz max - enables deterministic real-time task scheduling in motor control loops. |
| Flash Memory | 1 MB with Flash Accelerator - supports large firmware images and eliminates wait states up to 72 MHz operation. |
| SRAM | 128 KB total (64 KB SRAM0 + 64 KB SRAM1) - separates instruction/data and system bus traffic for concurrent CPU/DMA access. |
| ADC | 32-channel, 12-bit SAR, 1.0 μs @ 5 V - provides fast, high-resolution analog sensing for current/voltage feedback in inverters. |
| USB Interface | Dual-role USB 2.0 Full-Speed (Device + Host), 6 endpoints - enables field service via USB device mode and peripheral attachment via host mode. |
| QPRC Channels | 3 independent quadrature counters with 16-bit position/revolution counters - directly interfaces to incremental encoders for precise rotor position tracking. |
| Power Supply | VCC = 2.7–5.5 V; USBVCC0/1 = 3.0–3.6 V when used for USB - simplifies power design in mixed-signal industrial systems with shared rail constraints. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit motor control microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F303RET6 | ARM Cortex-M4F core, 72 MHz, 512 KB Flash, no native USB host, single QEI unit | Limited to USB device-only and single encoder interface; lacks dual-role USB and triple QPRC | Prefer when FPU-enabled math operations outweigh USB host and encoder count requirements |
| RA6M3GFP | ARM Cortex-M4, 200 MHz, 1 MB Flash, USB host/device, but no QPRC - uses general-purpose timers for encoder emulation | Requires software-based quadrature decoding, increasing CPU load and reducing real-time margin | Choose when higher CPU throughput is critical and encoder resolution can be traded for processing headroom |
Compared with STM32F303RET6 and RA6M3GFP, CY9BF316TBGL-GK7E1 uniquely delivers triple hardware QPRC, dual-role USB, and 144 MHz deterministic timing in a single 176-pin LQFP - reducing BOM count and firmware complexity in encoder-driven motor systems.

FAQ
What is the maximum operating frequency and how is it achieved?
The CY9BF316TBGL-GK7E1 achieves 144 MHz system clock via its Main PLL, which accepts input from either an external 4–48 MHz crystal or the internal 4 MHz CR oscillator. The PLL's output feeds the CPU, memory, and peripheral clocks, and the Flash Accelerator ensures zero-wait-state execution at this frequency by buffering instruction fetches and pre-decoding sequences.
Does this MCU support USB device and host simultaneously?
Yes - the MCU integrates two independent USB 2.0 Full-Speed PHYs: one dedicated to device mode (up to 6 endpoints) and another to host mode (supporting bulk/interrupt/isochronous transfers, automatic device detection, and 256-byte packet handling). Both operate concurrently without resource conflict, enabling hybrid use cases like local firmware update and peripheral attachment.
How many hardware quadrature encoder interfaces does it provide?
The MCU provides three independent Quadrature Position/Revolution Counter (QPRC) units. Each supports A/B/Z input with configurable edge detection, 16-bit position and revolution counters, and dual 16-bit compare registers - enabling direct connection to three separate incremental encoders for multi-axis motion control without software overhead.
What power-saving modes are supported and what peripherals remain active?
It supports SLEEP, TIMER, and STOP modes. In STOP mode, the low-speed sub-clock (32.768 kHz) remains active, allowing wake-up from QPRC events, USB suspend/resume, or external interrupts. The hardware watchdog (clocked by 100 kHz internal CR) also stays enabled, ensuring fail-safe reset capability even during deepest sleep.
