Infineon Technologies CY9BF514NPQC-G-JNE2

Overview

CY9BF514NPQC-G-JNE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller in the FM3 family, designed for motor control and industrial embedded systems. It operates up to 144 MHz, integrates 512 KB MainFlash with Flash Accelerator, 32 KB WorkFlash, 64 KB SRAM (split into SRAM0/SRAM1), dual CAN 2.0A/B interfaces (1 Mbps), and USB 2.0 Full-Speed device/host support.

For engineers reviewing the CY9BF514NPQC-G-JNE2 datasheet, CY9BF514NPQC-G-JNE2 pinout, CY9BF514NPQC-G-JNE2 application, or CY9BF514NPQC-G-JNE2 equivalent, key selection criteria include dual CAN channel timing integrity, 12-bit ADC conversion time (1.0 μs @ 5 V), real-time clock with leap-year support, QPRC encoder interface, and SWJ-DP debug with ETM trace capability.

Technical Context

This MCU implements a tightly coupled Arm Cortex-M3 r2p1 core with MPU and NVIC supporting 48 peripheral interrupts and 16 priority levels. Its memory subsystem features two independent Flash banks (MainFlash + WorkFlash) and dual-bus-connected SRAM blocks enabling concurrent instruction fetch and data access.

The peripheral set is optimized for motion control: three multi-function timers with dead-time insertion and DTIF interrupt, three QPRC channels for position/revolution counting, and motor-specific PWM/PPG waveform generation. USB and CAN are fully autonomous with built-in PLLs and message buffers-no host CPU intervention required for packet handling or CAN arbitration.

FAQ

What is the maximum operating frequency and how is it achieved?

The CY9BF514NPQC-G-JNE2 achieves up to 144 MHz CPU operation using its main PLL, which multiplies the 4–48 MHz external crystal input. The Flash Accelerator system eliminates wait states up to 72 MHz and maintains equivalent performance above that frequency by caching sequential instruction fetches - verified in the Rev. *E datasheet Section 12.4.4.

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. Device mode uses Endpoint 0–5 with 256-byte EP1 buffer for high-bandwidth transfers; host mode supports up to 256-byte packets and automatic device connect/disconnect detection, as detailed in Section 4.3 of the datasheet.

How many CAN message buffers are implemented and what is their allocation?

Each of the two CAN channels has 32 dedicated message buffers, independently configurable for transmit/receive and prioritized acceptance filtering. Buffers are managed by hardware FIFOs and support mailbox-style access - enabling deterministic latency for time-critical messages without CPU polling overhead.

Is the QPRC capable of handling index pulse (Z-phase) for homing operations?

Yes - the QPRC supports ZIN input with programmable edge sensitivity and automatic reset of position/revolution counters upon ZIN assertion. This enables precise mechanical homing in CNC axes or robotic joints, as confirmed in Section 4.10.3 of the peripheral manual and validated in application note AN94967.
