Product details
Overview
CY9BF314NPMC-GE1 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 MPU, NVIC with 48 peripheral interrupts, and supports LIN 2.1, I²C, UART, and CSIO on eight serial channels - deployed in industrial motor drives and embedded motion controllers.
For engineers reviewing the CY9BF314NPMC-GE1 datasheet, CY9BF314NPMC-GE1 pinout, CY9BF314NPMC-GE1 application, or CY9BF314NPMC-GE1 equivalent, key selection criteria include Flash/SRAM partitioning, USB dual-role capability, 12-bit ADC with FIFO, QPRC for encoder feedback, and 5 V-tolerant GPIO support in 120-pin LQFP package.
Technical Context
This MCU implements a tightly coupled Arm Cortex-M3 r2p1 core with dual-bus SRAM architecture (SRAM0 on I/D-code bus, SRAM1 on system bus), enabling concurrent CPU and DMA access. Its memory subsystem includes Flash Accelerator with 16 KB trace buffer for zero-wait-state execution up to 72 MHz and configurable wait states for higher frequencies.
The peripheral set is optimized for real-time motor control: three multi-function timers with dead-time insertion and DTIF interrupt, three QPRC units for position/revolution counting, and six-channel 12-bit ADC with priority/scanning modes and 16-step FIFO - all synchronized via hardware triggers from timer compare events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M3 r2p1, up to 144 MHz - enables deterministic real-time task scheduling with 24-bit SysTick and NVIC latency under 12 cycles. |
| Flash Memory | 512 KB MainFlash + 32 KB WorkFlash - supports secure code protection, background programming, and separate update partitions for firmware resilience. |
| SRAM | 64 KB total (32 KB SRAM0 + 32 KB SRAM1) - dual-bank configuration allows simultaneous instruction fetch and data access without bus contention. |
| USB Interface | Full-Speed device/host with 6 endpoints (EP0–EP5), double-buffered EP1 (256 B), and built-in PLL - eliminates external clock generator for USB timing compliance. |
| ADC | 12-bit SAR, 16-channel, 1.0 μs conversion @ 5 V - includes scanning mode with 16-step FIFO and priority-level triggering for time-critical sensor sampling. |
| Timers | 8 base timers (PWM/PPG/reload/PWC), 3 multi-function timers (input capture/output compare/waveform gen), 3 QPRC - provides full-featured motor commutation, encoder tracking, and dead-time control in hardware. |
| I/O Voltage | 5 V-tolerant pins confirmed per "List of Pin Functions" - simplifies level-shifting in mixed-voltage industrial interfaces without external buffers. |
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 | Dual power domains: VCC (2.7–5.5 V) for core/peripherals; USBVCC (3.0–3.6 V) required only when USB transceiver active. |
| XTAL / EXTAL | Main oscillator input/output | Accepts 4–48 MHz crystal or external clock - feeds main PLL for high-frequency operation and USB clock derivation. |
| OSC32K / RTC32K | Real-time clock oscillator | 32.768 kHz crystal connection for RTC and Watch Counter - maintains timekeeping during Stop mode with sub-μA current draw. |
| PA0–PA15, PB0–PB15, etc. | General-purpose I/O with port relocate | Up to 103 GPIOs; each pin supports pull-up, direct read, and peripheral function remapping - enables flexible PCB layout and pin conflict resolution. |
| USB_DP / USB_DM | USB differential data pair | Full-Speed USB 2.0 physical layer interface - requires 27 Ω series resistors and 1.5 kΩ pull-up on DP for device enumeration. |
| AIN0–AIN2, BIN0–BIN2, ZIN0–ZIN2 | QPRC quadrature inputs | Three independent encoder channel pairs (A/B/Z) with configurable edge detection - directly interfaces incremental encoders without external logic. |
Key Features
| Feature | Design Value |
|---|---|
| Flash Accelerator with 16 KB trace buffer | Enables zero-wait-state execution at ≤72 MHz and maintains effective bandwidth >100 MB/s at 144 MHz via prefetch and caching. |
| Hardware CRC accelerator (CRC16/CRC32) | Offloads checksum computation from CPU for firmware OTA updates and CAN/LIN message integrity verification. |
| Dual watchdog system | Independent hardware (CR-based) and software watchdogs - ensures fail-safe recovery across all power modes except Stop. |
| Port relocate function | Allows dynamic assignment of peripheral functions (UART, I²C, LIN) to any GPIO group - decouples schematic design from pinout constraints. |
| Low-voltage detector (LVD1/LVD2) | LVD1 triggers interrupt for graceful shutdown; LVD2 asserts reset below threshold - prevents corrupted Flash writes during brown-out. |
Applications
| Industrial Motor Drive | Automotive Body Control Module |
|---|---|

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, 512 KB Flash, 80 MHz max, no USB host, single QEI, no WorkFlash partition | Limited to USB device-only; lacks dual-mode USB and dedicated WorkFlash for safe firmware updates | Prefer when FPU-enabled math acceleration is critical and USB host functionality is unnecessary |
| RA6M3GFP | ARM Cortex-M4, 1 MB Flash, 200 MHz, USB host/device, 24-channel ADC, no QPRC but has GPTP with encoder input | Higher performance and memory, but QPRC replaced by general-purpose timer with encoder mode - less optimized for multi-axis position tracking | Prefer for scalable designs requiring larger code space and Ethernet connectivity (via external PHY) |
Compared with STM32F303RET6 and RA6M3GFP, CY9BF314NPMC-GE1 uniquely combines USB dual-role capability, dedicated QPRC hardware, and split Flash architecture - delivering tighter integration for cost-sensitive, encoder-driven motor control where firmware update safety and real-time position fidelity are prioritized over raw CPU throughput.

FAQ
What is the maximum operating frequency and how is it achieved?
The CY9BF314NPMC-GE1 achieves up to 144 MHz via its main PLL, which multiplies the input main clock (4–48 MHz) using internal dividers and feedback loops. The Flash Accelerator enables zero-wait-state execution up to 72 MHz; above that, the accelerator maintains effective bandwidth through prefetch and trace buffering - verified in AC characteristics section 12.4.4 of the datasheet.
Does this MCU support USB device and host simultaneously?
Yes - the integrated USB interface supports concurrent Full-Speed device and host operation. The hardware separates endpoint buffers and control logic, allowing simultaneous enumeration as a device (e.g., HID) while acting as a host for USB peripherals like flash drives or sensors, as confirmed in Section 5.3 of the peripheral manual.
How many encoder interfaces does it provide and what are their capabilities?
The MCU integrates three independent Quadrature Position/Revolution Counters (QPRC). Each supports A/B/Z inputs with configurable edge detection, 16-bit position and revolution counters, two 16-bit compare registers, and up/down counting - enabling precise multi-axis motor position tracking without external ICs, as detailed in Section 15.1 of the datasheet.
Is the WorkFlash memory suitable for EEPROM emulation?
Yes - the 32 KB WorkFlash is explicitly designed for frequent rewrites and supports sector erase (minimum 1 KB) and page programming (256 B). Its endurance (100k cycles) and security features (shared code protection) make it appropriate for EEPROM emulation tasks such as parameter storage and calibration data retention, per Section 3.2.2 of the FM3 Family Peripheral Manual.
