Product details
Overview
CY9BF316NPMC-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, includes Memory Protection Unit (MPU), NVIC with 48 peripheral interrupts, and supports industrial embedded control in motor drives and industrial automation systems.
For engineers reviewing the CY9BF316NPMC-G-JNE2 datasheet, CY9BF316NPMC-G-JNE2 pinout, CY9BF316NPMC-G-JNE2 application, or CY9BF316NPMC-G-JNE2 equivalent, key selection criteria include Flash/SRAM partitioning, dual USB device/host capability, LIN 2.1 support, 12-bit ADC with 1.0 μs conversion time, and QPRC for encoder-based position sensing.
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 storage (WorkFlash), each with distinct wait-state behavior and shared security protection.
The peripheral set is optimized for real-time motion control: three multi-function timers provide PWM, dead-time insertion, and A/D trigger synchronization; QPRC channels track quadrature encoder inputs; and LIN/UART/CSIO/I²C serial interfaces enable distributed sensor and actuator communication in deterministic industrial networks.
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 response |
| MainFlash | 512 KB with Flash Accelerator - zero-wait access ≤72 MHz; maintains performance at higher frequencies via trace buffer |
| SRAM | 64 KB split across SRAM0 (I/D bus) and SRAM1 (system bus) - supports concurrent CPU and DMA access without contention |
| USB Interface | Full-Speed device/host with 6 endpoints, 256-byte EP1 buffer - enables dual-role connectivity for firmware updates and host-side diagnostics |
| ADC | 12-bit SAR, 1.0 μs conversion @5 V, 16-channel scan mode with FIFO - meets timing-critical sampling in motor current sensing |
| QPRC | 3 channels, 16-bit position + 16-bit revolution counters with configurable A/B/Z edge detection - directly interfaces standard incremental encoders |
| Power Supply | VCC = 2.7–5.5 V; USBVCC = 3.0–3.6 V (USB active) - supports mixed-voltage system integration with robust brown-out handling |
Pinout & Package
Package: 120-pin LQFP (14 mm × 14 mm, 0.4 mm pitch). Pin mapping follows CY9B310R Series Pin Assignments (Document 002-05619 Rev. *F, Pages 10–13), with dedicated functions for USB D+/D−, QPRC AIN/BIN/ZIN, ADC inputs, PWM outputs, and external bus interface signals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply / Ground | Dual power domains: VCC for core/peripherals (2.7–5.5 V), USBVCC for USB I/O (3.0–3.6 V when active) |
| USB_DP / USB_DM | USB 2.0 Full-Speed differential pair | On-die termination and internal pull-up enable plug-and-play device enumeration without external components |
| AIN0 / BIN0 / ZIN0 | Quadrature encoder input channels | Configurable digital filter and edge sensitivity per channel - suppresses mechanical bounce in rotary encoder signals |
| AD00–AD15 | Analog input channels | 12-bit ADC inputs with selectable reference (VREFH/VREFL); some pins support 5 V tolerant digital I/O when not used for analog |
| MTIOC0A / MTIOC0B | Motor timer output compare pins | Hardware-synchronized PWM outputs with programmable dead-time insertion - eliminates shoot-through risk in H-bridge gate drive |
Key Features
| Feature | Design Value |
|---|---|
| Dual Flash architecture | MainFlash (512 KB) for code execution; WorkFlash (32 KB) for parameter storage - enables field firmware updates without erasing operational code |

| LIN 2.1 protocol engine | Hardware-accelerated LIN master/slave with programmable break field (13–16 bit) and delimiter (1–4 bit) - ensures compliance with automotive sub-system communication standards |
| CRC accelerator | Hardware CCITT CRC16 and IEEE-802.3 CRC32 - offloads integrity checking from CPU during bootloader validation and CAN/LIN message processing |
| SWJ-DP debug interface | Serial Wire JTAG Debug Port with ETM trace - enables non-intrusive real-time instruction tracing and variable watchpoints in safety-critical development |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit Arm Cortex-M3 microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F103VCT6 | 72 MHz max clock; 256 KB Flash, 48 KB SRAM; no native LIN or QPRC; USB device only | Lacks hardware LIN 2.1 and quadrature counter - requires software emulation or external logic for encoder/motor control | Prefer when cost-sensitive designs omit advanced motor control or automotive networking |
| RA4M1 (R7FA4M1AB3CFM) | 48 MHz max clock; 256 KB Flash, 32 KB SRAM; no USB host; no QPRC; supports CAN FD | Includes CAN FD but omits USB host and QPRC - better suited for vehicle network gateways than motor position feedback | Choose when CAN FD interoperability outweighs USB dual-role and encoder interface needs |
Compared with STM32F103VCT6 and RA4M1, CY9BF316NPMC-G-JNE2 uniquely integrates USB device/host, LIN 2.1, and QPRC in a single 120-pin LQFP package - reducing BOM count and PCB area for industrial motion control where both fieldbus connectivity and precise position tracking are required.

FAQ
What is the maximum operating frequency and how is it achieved?
The CY9BF316NPMC-G-JNE2 achieves up to 144 MHz using its main PLL, which multiplies an external 4–48 MHz crystal or oscillator input. The Flash Accelerator enables zero-wait-state execution at ≤72 MHz and maintains effective performance above that via a 16 KB trace buffer, eliminating pipeline stalls during instruction fetch.
Does this MCU support USB host functionality without external PHY?
Yes - the MCU integrates a full USB 2.0 Full-Speed host controller with built-in PHY, supporting bulk/interrupt/isochronous transfers, automatic device connect/disconnect detection, and IN/OUT token handshake. No external transceiver is needed for basic USB host operation with low-/full-speed peripherals.
How does the dual Flash architecture improve firmware update reliability?
MainFlash stores application code and executes directly; WorkFlash holds configuration data and firmware images. During OTA updates, new firmware is written to WorkFlash while the system runs from MainFlash. Atomic swap and checksum verification prevent partial writes, ensuring boot integrity even after power loss mid-update.
Can the QPRC operate independently of the CPU core clock?
Yes - the QPRC uses its own dedicated clock domain derived from the peripheral clock (PCLK), allowing continuous position counting during Sleep or Stop modes. Its 16-bit position and revolution counters retain values across low-power states, enabling wake-up on encoder movement without CPU intervention.
