Product details
Overview
CY9BF516NPQC-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, dual CAN 2.0B interfaces, USB 2.0 Full-Speed device/host, and 12-bit ADC with 16 channels - designed for motor control, industrial automation, and embedded real-time systems requiring deterministic timing and mixed-signal integration.
For engineers reviewing the CY9BF516NPQC-G-JNE2 datasheet, CY9BF516NPQC-G-JNE2 pinout, CY9BF516NPQC-G-JNE2 application, or CY9BF516NPQC-G-JNE2 equivalent, key selection criteria include its 144 MHz max CPU frequency, dual CAN + USB + LIN support, 5 V-tolerant GPIOs, Flash accelerator enabling zero-wait-state operation up to 72 MHz, and integrated motor control peripherals including QPRC and multi-function timers.
Technical Context
This MCU implements an Arm Cortex-M3 r2p1 core with Memory Protection Unit (MPU), NVIC supporting 48 peripheral interrupts across 16 priority levels, and SysTick timer for RTOS scheduling. It integrates dual independent Flash banks (MainFlash + WorkFlash) with shared code protection and configurable wait states based on operating frequency.
The peripheral set includes three multi-function timer units supporting PWM, dead-time insertion, and A/D activation; three QPRC channels for encoder position tracking; and a DMA controller with eight channels supporting burst/block transfers across 4 GB address space - all synchronized via a flexible clock system with five sources (external oscillators, internal CR clocks, and dual PLLs).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M3 r2p1, up to 144 MHz - enables real-time deterministic execution with hardware divide and Thumb-2 instruction set. |
| Flash Memory | 512 KB MainFlash + 32 KB WorkFlash - supports secure firmware updates, dual-bank operation, and zero-wait-state access ≤72 MHz. |
| SRAM | 64 KB total (32 KB SRAM0 + 32 KB SRAM1) - split I/D and system bus connectivity optimizes core and peripheral data throughput. |
| CAN Interface | Two CAN 2.0A/B channels, 1 Mbps max - enables robust fieldbus communication in automotive body control and industrial PLC nodes. |
| USB Interface | Full-Speed USB 2.0 device/host with built-in PLL - eliminates external clock source requirement and supports endpoint double buffering (up to 256-byte EP1). |
| A/D Converter | 12-bit SAR ADC, 16 channels, 1.0 μs conversion @ 5 V - provides high-resolution analog sensing for motor current/voltage feedback loops. |
| Power Supply | VCC = 2.7–5.5 V; USBVCC = 3.0–3.6 V (USB active) - supports direct connection to industrial 3.3 V/5 V rails without level-shifting. |
Pinout & Package
Package: 120-pin LQFP (14 mm × 14 mm, 0.4 mm pitch), RoHS-compliant, with 103 fast general-purpose I/O pins - 5 V tolerant on designated pins per "List of Pin Functions" (Datasheet Rev. *E, p.14).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply / Ground | Dual power domains: VCC powers core/peripherals; separate USBVCC required only when USB PHY is active. |
| XTAL / EXTAL | Main clock oscillator input/output | Supports 4–48 MHz crystal; enables precise timing for CAN, USB, and real-time control loops. |
| USB_DP / USB_DM | USB 2.0 differential data pair | Integrated transceiver compliant with Full-Speed signaling; requires 1.5 kΩ pull-up on DP for device enumeration. |
| CAN0_TX / CAN0_RX | Channel 0 CAN transceiver interface | Direct connection to external CAN transceiver (e.g., TJA1042); supports 1 Mbps bit rate with loopback test mode. |
| AD00–AD15 | Analog input channels | 16 dedicated ADC inputs mapped to GPIO pins; support simultaneous sampling via scanning mode and FIFO-based data capture. |
Key Features
| Feature | Design Value |
|---|---|
| Flash Accelerator with 16 KB trace buffer | Enables zero-wait-state execution at ≤72 MHz and maintains effective bandwidth >72 MHz via prefetch and caching - critical for interrupt latency consistency. |
| Motor Control Timer Units (3) | Each unit integrates PWM, PPG, input capture, A/D activation, and DTIF emergency stop - allows single-chip implementation of 3-phase BLDC/PMSM commutation. |
| Quadrature Position Counter (3 channels) | 16-bit position + 16-bit revolution counters with configurable A/B/Z edge detection - eliminates need for external encoder interface ICs in servo drives. |
| Dual CAN + USB + LIN + I²C + UART | Multi-protocol serial stack on one die - supports gateway functionality between CAN fieldbus, USB host diagnostics, and LIN sensor networks. |
| Hardware Watchdog + Software Watchdog | Independent reset sources: hardware watchdog runs on 100 kHz CR oscillator (active in all modes except Stop), software watchdog uses main clock - ensures fail-safe recovery under clock fault or firmware hang. |
Applications
| Industrial Motor Drive | Automotive Body Control Module |
|---|---|
Use Scenario: Closed-loop control of 3-phase BLDC motors in HVAC blowers or pump systems using hall-effect or encoder feedback. IC Role / Device Role / Timing Role: Real-time execution of FOC algorithm, PWM generation with dead-time insertion, and ADC sampling synchronized to switching cycles.

IC Role / Device Role / Timing Role: USB host managing flash storage dongles for firmware updates, CAN node relaying DLMS/COSEM messages, and RTC maintaining accurate billing timestamps. Use Value: Integrated RTC with leap-year correction and alarm interrupts ensures time-stamped event logging compliant with IEC 62056; USB host avoids external micro-B connector ICs. |
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 |
|---|---|---|---|
| STM32F207ZGT6 | 120 MHz Cortex-M3, 1 MB Flash, 128 KB RAM, single CAN, no native LIN or QPRC | Lacks integrated LIN master and quadrature encoder counter - requires external components for motor position sensing | Preferred where larger Flash/RAM and Ethernet MAC are needed, but adds complexity for motor control or LIN subsystems |
| RA4M1 (R7FA4M1AB3CFM) | 48 MHz Cortex-M4F, 256 KB Flash, 32 KB RAM, single CAN, no USB host, no QPRC | No USB host or QPRC; uses Renesas' Flexible Software Package instead of CMSIS - increases porting effort for legacy FM3 code | Suitable for cost-sensitive, low-power HMI or sensor hub designs where USB host and encoder counting are not required |
Compared with STM32F207ZGT6 and RA4M1, CY9BF516NPQC-G-JNE2 uniquely combines dual CAN, USB host/device, LIN master, and QPRC in a single 120-pin LQFP package - reducing system-level component count and PCB area for motion-control and automotive gateway applications.

FAQ
What is the maximum operating frequency and how is it achieved?
The CY9BF516NPQC-G-JNE2 achieves up to 144 MHz CPU operation using the main PLL with a 4–48 MHz external crystal input. The Flash accelerator enables zero-wait-state execution at frequencies ≤72 MHz; above that, the accelerator maintains effective bandwidth through prefetch and trace buffer utilization - verified in Datasheet Rev. *E Section 12.4.4.
Does this MCU support USB host mode with external device enumeration?
Yes - the integrated USB host controller supports Full-Speed and Low-Speed devices, automatic connect/disconnect detection, IN/OUT token handshake, and up to 256-byte packet length. It requires no external PHY and has been validated with HID keyboards, mass-storage devices, and USB-to-serial adapters per Application Note AN91184.
How many CAN message buffers are implemented and what is their allocation method?
The MCU implements 32 dedicated CAN message buffers, statically allocated across two CAN channels. Buffers support transmit/receive prioritization, FIFO/queue modes, and acceptance filtering - managed via CAN Mailbox Registers (CMR) and configured in software per the FM3 Peripheral Manual TYPE4 specification.
Is the WorkFlash memory independently erasable and usable for EEPROM emulation?
Yes - the 32 KB WorkFlash is electrically isolated from MainFlash and supports sector erase (1 KB sectors) and byte/word programming. Its endurance (100k cycles) and retention (20 years) meet EEPROM emulation requirements; Cypress-provided middleware (FM3 Flash Library) includes wear-leveling and error-correction routines for robust data logging.
