Infineon Technologies CY9BF316NPQC-G-JNE2

Overview

CY9BF316NPQC-G-JNE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller in the FM3 family, designed for embedded motor control and industrial automation. It operates up to 144 MHz, integrates 512 KB MainFlash with Flash Accelerator, 32 KB WorkFlash, 64 KB SRAM (split into SRAM0/SRAM1), and features USB 2.0 Full-Speed Device/Host, 12-bit ADC (16 channels, 1.0 µs conversion), and dedicated motor control peripherals including QPRC, Base Timers, and Multi-function Timers.

For engineers reviewing the CY9BF316NPQC-G-JNE2 datasheet, CY9BF316NPQC-G-JNE2 pinout, CY9BF316NPQC-G-JNE2 application, or CY9BF316NPQC-G-JNE2 equivalent, key selection criteria include its dual Flash architecture, 120-pin LQFP package with 103 GPIOs (some 5 V tolerant), integrated USB PHY, real-time clock, and hardware CRC accelerator supporting CCITT CRC16 and IEEE-802.3 CRC32.

Technical Context

The CY9BF316NPQC-G-JNE2 implements an Arm Cortex-M3 r2p1 core with Memory Protection Unit (MPU) and NVIC supporting 48 peripheral interrupts across 16 priority levels. Its clock system includes five sources-two external oscillators (Main Clock 4–48 MHz, Sub Clock 32.768 kHz), two internal CR oscillators (4 MHz high-speed, 100 kHz low-speed), and dual PLLs (Main PLL and USB PLL)-enabling dynamic clock switching and robust failure detection via Clock Supervisor (CSV).

Peripheral integration targets deterministic real-time control: three QPRC channels for encoder position tracking, three multi-function timers with dead-time insertion and A/D activation triggers, and eight-channel DMA with independent bus access. Power management includes Sleep, Timer, and Stop modes, with LVD1/LVD2 monitoring and dual watchdogs (hardware-reset-capable CR-based and software-configurable).

FAQ

What is the maximum operating frequency and supported voltage range for CY9BF316NPQC-G-JNE2?

The CY9BF316NPQC-G-JNE2 operates at up to 144 MHz using its Main PLL and supports a wide VCC supply range of 2.7 V to 5.5 V. USB I/O requires USBVCC between 3.0 V and 3.6 V when the USB interface is active; otherwise, USBVCC can operate across the full 2.7–5.5 V range for GPIO functionality. The device includes LVD1/LVD2 monitoring to ensure safe operation under voltage fluctuations.

Does CY9BF316NPQC-G-JNE2 support USB Host mode, and what peripherals does it require?

Yes, CY9BF316NPQC-G-JNE2 supports USB 2.0 Full-Speed and Low-Speed Host mode with automatic device connect/disconnect detection, IN/OUT token handshake, and up to 256-byte packet length. No external PHY is needed-the USB DP/DM pins connect directly to downstream devices. External components include standard USB ESD protection diodes and 27 Ω series resistors on DP/DM lines per USB specification.

How many ADC channels and what resolution/timing does the integrated ADC offer?

The device integrates a 12-bit successive approximation register (SAR) ADC with up to 16 input channels. Conversion time is 1.0 µs at 5 V supply. It supports scanning mode with 16-step FIFO and priority-based conversion with 4-step FIFO. Three independent ADC units allow parallel sampling, and conversions can be triggered by timers or software for precise synchronization.

Is the CY9BF316NPQC-G-JNE2 pin-compatible with other FM3 series MCUs?

No-CY9BF316NPQC-G-JNE2 uses a 120-pin LQFP package specific to the CY9B310R series within the FM3 family. While pin functions follow FM3 TYPE4 peripheral mapping, mechanical and electrical compatibility is not guaranteed across other FM3 subfamilies (e.g., CY9B510R or CY9B210R) due to differences in peripheral allocation, power domains, and I/O voltage tolerance configurations.
