Product details
Overview
CY9BF314NPQC-G-JNE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 512 KB MainFlash, 32 KB WorkFlash, 64 KB SRAM, USB 2.0 Full-Speed device/host interface, and integrated motor control timers. It operates up to 144 MHz, features Memory Protection Unit (MPU), NVIC with 48 peripheral interrupts, and supports real-time applications in industrial motor drives and embedded controllers.
For engineers reviewing the CY9BF314NPQC-G-JNE2 datasheet, CY9BF314NPQC-G-JNE2 pinout, CY9BF314NPQC-G-JNE2 application, or CY9BF314NPQC-G-JNE2 equivalent, key selection criteria include Flash/SRAM partitioning, dual USB mode support, 12-bit ADC with FIFO, QPRC for encoder feedback, and 5 V-tolerant GPIOs on 120-pin LQFP package.
Technical Context
This MCU implements a full Arm Cortex-M3 r2p1 core with tightly coupled I/D buses, MPU-enforced memory isolation, and SysTick for RTOS scheduling. Its dual Flash architecture separates executable code (MainFlash) from configuration/data (WorkFlash), each with distinct wait-state behavior and shared security protection.
The peripheral set targets motion control: three multi-function timers with dead-time insertion and A/D activation, three QPRC channels for position sensing, LIN 2.1 support for automotive sub-systems, and USB host/device dual-role capability with built-in PLL and endpoint buffering - all synchronized via a flexible clock system with five sources and CSV supervision.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M3 r2p1, up to 144 MHz - enables deterministic real-time execution with low-latency interrupt handling |
| MainFlash | 512 KB with Flash Accelerator - zero-wait access ≤72 MHz; maintains performance at higher frequencies via trace buffer |
| SRAM | 64 KB split as SRAM0 (32 KB, I/D bus) + SRAM1 (32 KB, system bus) - optimizes core and DMA concurrency |
| ADC | 12-bit SAR, 16-channel, 1.0 μs conversion @5 V - supports high-speed sensor sampling with priority/scanning modes and FIFO buffering |
| USB Interface | Full-Speed device/host with 6 endpoints, built-in PLL - eliminates external clock source; double-buffered endpoints enable robust data streaming |
| Package | 120-pin LQFP (14 × 14 mm, 0.4 mm pitch) - provides 103 GPIOs including 5 V-tolerant pins for mixed-voltage interfacing |
| Power Supply | VCC = 2.7–5.5 V; USBVCC = 3.0–3.6 V (USB active) - supports direct connection to industrial 3.3 V or 5 V rails |
Pinout & Package
Package: 120-pin LQFP (14 mm × 14 mm, 0.4 mm pitch), RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply / Ground | Dedicated power/ground pairs per quadrant minimize noise coupling and ensure stable core/peripheral operation |

| USB_DP / USB_DM | USB 2.0 differential data lines | Internally terminated; require no external resistors when used in Full-Speed device mode |
| AINx / BINx / ZINx | Quadrature encoder inputs (QPRC) | Configurable edge detection per channel; feed position/revolution counters without CPU intervention |
| MTIOCx | Motor timer output compare | Generates PWM, PPG, or dead-time-inserted waveforms directly from timer hardware |
Key Features
| Feature | Design Value |
|---|---|
| Dual Flash architecture | MainFlash (512 KB) for code + WorkFlash (32 KB) for parameters - enables field firmware updates without erasing operational code |
| USB dual-role controller | Integrated device/host PHY and endpoint buffers - allows single MCU to act as USB peripheral or host for diagnostics/programming |
| QPRC with ZIN indexing | Three independent 16-bit position/revolution counters with configurable A/B/Z input edges - supports absolute encoder homing and multi-turn tracking |
| Motor control timer suite | Three multi-function timers with DTIF emergency stop, A/D activation, and waveform generation - reduces external gate-driver logic |
| Flexible clock supervision | Clock Supervisor (CSV) monitors external oscillator failure/frequency drift - triggers reset or interrupt to maintain timing integrity |
Applications

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 |
|---|---|---|---|
| STM32F303VCT6 | ARM Cortex-M4F core, 256 KB Flash, 48 KB SRAM, no integrated USB host mode | Lacks USB host capability and QPRC; includes FPU and op-amps for analog signal conditioning | Select when floating-point math or analog front-end integration outweighs USB dual-role and encoder counter needs |
| RA4M1 (R7FA4M1AB3CFM) | ARM Cortex-M4, 256 KB Flash, 32 KB SRAM, USB device-only, no WorkFlash partitioning | No WorkFlash or dual USB mode; adds TrustZone security but lacks motor-specific peripherals like DTIF | Prefer for secure boot and OTA update scenarios where motor control complexity is lower |
Compared with STM32F303VCT6 and RA4M1, CY9BF314NPQC-G-JNE2 uniquely combines USB device/host duality, dedicated QPRC hardware, and separate WorkFlash for safe parameter storage - making it optimal for cost-sensitive, encoder-based motion control with field-upgradable firmware.

FAQ
What is the maximum operating frequency and how is it achieved?
The CY9BF314NPQC-G-JNE2 achieves up to 144 MHz via its internal Main PLL, which multiplies the main clock (4–48 MHz crystal or external source). The Flash Accelerator enables zero-wait-state execution at ≤72 MHz and maintains effective performance above that by caching instruction traces - confirmed in Section 12.4.4 of the datasheet.
Does this MCU support USB device and host simultaneously?
No - the USB interface supports device mode and host mode, but not simultaneous dual-role operation. Mode selection is configured at initialization via USB control registers. Device mode uses internal pull-ups and endpoint 0–5; host mode requires external VBUS sensing and supports up to two downstream devices - both modes share the same DP/DM pins and PLL clock source.
How many 5 V-tolerant I/O pins does CY9BF314NPQC-G-JNE2 have?
Per the "List of Pin Functions" (Section 4) in the datasheet, 42 GPIO pins are explicitly marked as 5 V-tolerant, including key signals such as MTIOCx outputs, QPRC inputs (AIN/BIN/ZIN), and several UART/CSIO lines. Tolerance applies only when VCC ≥ 3.0 V and must be verified against Table 12.3.2 for specific pin numbers.
Is the WorkFlash memory suitable for storing calibration data?
Yes - WorkFlash (32 KB) is designed for non-volatile parameter storage, including calibration coefficients, device IDs, and runtime configuration. It supports independent erase/write cycles, shares security protection with MainFlash, and has defined wait states (0–4) based on operating frequency - making it ideal for field-updatable calibration data without disturbing application code.
