Product details
Overview
CY9BF318TBGL-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 control and embedded automation.
For engineers reviewing the CY9BF318TBGL-GK7E1 datasheet, CY9BF318TBGL-GK7E1 pinout, CY9BF318TBGL-GK7E1 application, or CY9BF318TBGL-GK7E1 equivalent, key selection criteria include Flash/SRAM size, USB dual-role capability, real-time motor timing features (QPRC, dead-time PWM), 12-bit ADC performance, and 176-pin LQFP package compatibility with industrial I/O requirements.
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. Its clock system integrates five sources - main oscillator (4–48 MHz), sub-clock (32.768 kHz), high-speed/low-speed internal CR oscillators, and dual PLLs - enabling robust clock supervision and fail-safe reset via CSV and LVD.
The peripheral set is optimized for closed-loop motion control: three QPRC channels decode quadrature encoder signals with 16-bit position/revolution counters; multi-function timers provide PWM, PPG, input capture, A/D activation, and DTIF emergency stop; and dual USB channels support simultaneous device/host operation with configurable endpoints and double-buffered transfers.
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 protocol stacks. |
| Flash Memory | 1 MB with Flash Accelerator - zero-wait-state access ≤72 MHz; sustained performance >72 MHz via trace buffer and accelerator. |
| SRAM | 128 KB split into SRAM0 (64 KB, I/D bus) and SRAM1 (64 KB, system bus) - supports concurrent CPU/DMA access without contention. |
| ADC | 32-channel 12-bit SAR ADC, 1.0 μs conversion @5 V - meets fast sampling needs in servo current sensing and voltage monitoring. |
| USB Interface | Dual-channel USB 2.0 Full-Speed: Device (6 EP, double-buffered) + Host (256-byte packets, auto-connect detect) - enables embedded host-peripheral bridging. |
| QPRC Channels | 3 independent Quadrature Position/Revolution Counters - each with configurable A/B/Z edge detection, 16-bit counters, and compare registers for precise encoder position tracking. |
| Power Supply | VCC: 2.7–5.5 V; USBVCC0/1: 3.0–3.6 V when used for USB I/O - supports mixed-voltage system integration with legacy 5 V peripherals. |
Pinout & Package
Package: 176-pin LQFP (24 × 24 mm, 0.5 mm pitch), RoHS-compliant, with 154 fast GPIOs, 5 V-tolerant pins on selected I/Os, and dedicated power/ground distribution for noise-sensitive analog and USB domains.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Core power / ground | Dedicated pairs per quadrant minimize IR drop and switching noise in high-frequency operation. |
| USB_DP0 / USB_DM0 | USB Channel 0 differential data | ESD-protected, 3.3 V I/O domain; require 90 Ω differential impedance routing for Full-Speed compliance. |
| AIN0–AIN2 / BIN0–BIN2 / ZIN0–ZIN2 | QPRC channel inputs | Three independent quadrature encoder interfaces with programmable edge sensitivity and digital filtering. |
| AD0–AD31 | Analog input channels | 32 single-ended or 16 differential inputs mapped to 12-bit SAR ADC with FIFO-based scan sequencing. |
| PA0–PA15, PB0–PB15, etc. | Multi-function GPIO | Port relocate function allows dynamic assignment of UART/CSIO/I²C/LIN/Timer functions to physical pins. |
Key Features
| Feature | Design Value |
|---|---|
| Motor Control Timer Suite | 16-channel Base Timer + 3-unit Multi-function Timer with dead-time insertion, DTIF interrupt, and A/D activation triggers - enables field-oriented control (FOC) and sensorless BLDC commutation. |
| USB Dual Role | Simultaneous Device and Host operation with automatic connect/disconnect detection - eliminates need for external USB switch ICs in gateway or HMI applications. |
| Clock Supervision | Clock Supervisor (CSV) monitors external oscillator frequency and stop conditions using internal CR clocks - provides hardware-level clock fault recovery without software intervention. |
| Low-Power Modes | SLEEP, TIMER, and STOP modes with wake-up from QPRC, UART, or watchdog - extends battery life in portable motorized equipment while retaining encoder state. |
| CRC Accelerator | Hardware CCITT CRC16 and IEEE-802.3 CRC32 engines - offloads integrity checking from CPU during firmware updates or CAN/LIN message validation. |
Applications
| Industrial Motor Drive | Automated Test Equipment |
|---|---|

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, no native USB host, single QEI module | Lacks dual USB role and dedicated QPRC; requires external PHY for USB host; limited encoder counter resolution (32-bit only) | Preferred where FPU-based math acceleration is critical and USB host is not required. |
| RA6M4 Group (R7FA6M4AF3CFP) | ARM Cortex-M4F, 1 MB Flash, 384 KB SRAM, USB host/device, no QPRC - uses general-purpose timers for encoder counting | Higher SRAM but no hardware QPRC; relies on timer input capture with software-based revolution wrap handling | Chosen when advanced security (TrustZone) and larger RAM for RTOS+networking stacks outweigh dedicated motor timing IP. |
Compared with STM32F407VGT6 and RA6M4, CY9BF318TBGL-GK7E1 delivers unique hardware QPRC, dual USB role, and motor-specific DTIF interrupt - reducing firmware complexity and latency in encoder-coupled motion control, while maintaining full compatibility with existing FM3 ecosystem toolchains and pinouts.

FAQ
What debug interfaces does CY9BF318TBGL-GK7E1 support?
It supports Serial Wire JTAG Debug Port (SWJ-DP) with Embedded Trace Macrocell (ETM) for real-time instruction trace and non-intrusive debugging. No SWD-only or cJTAG variants - full JTAG boundary-scan and SWD are both enabled via the same 5-pin header (TCK, TMS, TDI, TDO, nTRST). ETM trace buffer size is 16 KB, accessible through CoreSight infrastructure.
Does this MCU support USB suspend/resume and remote wakeup?
Yes - USB Device mode supports suspend detection via IDLE signaling and remote wakeup via SE0 pulse generation. USB Host mode supports wakeup on device connect/disconnect events. Both rely on dedicated USB clock gating and low-power USB transceiver circuitry, with resume timing compliant to USB 2.0 Full-Speed specification (≤5 ms).
Can the 12-bit ADC operate synchronously with PWM timers?
Yes - Base Timers and Multi-function Timers include A/D activation compare units that trigger ADC conversions on PWM edge events (e.g., center-aligned PWM zero-crossing). This enables precise current sampling at optimal electrical angles in motor control, with hardware synchronization eliminating jitter from software-triggered conversions.
Is the Flash memory protected against unauthorized readout?
Yes - it includes a security function that disables Flash readout via debug interface when enabled. Protection is enforced by fuse bits controlling DBGACC and SWJ-DP access; once locked, only mass erase resets protection. Code protection does not affect normal program execution or bootloader operation - only external readout and debug access.
