Infineon Technologies CY9BF514NPMC-G-JNE1

Overview

CY9BF514NPMC-G-JNE1 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 512 KB MainFlash, 32 KB WorkFlash, 64 KB SRAM, integrated USB 2.0 Full-Speed device/host, dual CAN 2.0A/B controllers (1 Mbps), and 12-bit ADC (16 channels, 1.0 µs conversion). It targets motor control and industrial embedded systems requiring real-time peripherals including QPRC, multi-function timers, and LIN/UART/I²C/CSIO serial interfaces.

For engineers reviewing the CY9BF514NPMC-G-JNE1 datasheet, CY9BF514NPMC-G-JNE1 pinout, CY9BF514NPMC-G-JNE1 application, or CY9BF514NPMC-G-JNE1 equivalent, key selection criteria include USB/CAN coexistence, 144 MHz max CPU frequency, Flash accelerator enabling zero-wait-state operation up to 72 MHz, dual SRAM banks for deterministic memory access, and hardware CRC32/CCITT acceleration for firmware integrity verification.

Technical Context

This MCU implements a tightly coupled Arm Cortex-M3 r2p1 core with MPU and NVIC supporting 48 peripheral interrupts across 16 priority levels. Its memory subsystem separates instruction (SRAM0) and system (SRAM1) buses, enabling concurrent CPU and DMA access without contention.

The peripheral set is optimized for motion control: dual CAN channels share message RAM but operate independently; QPRC units accept A/B/Z encoder inputs with configurable edge detection; and multi-function timers provide PWM, dead-time insertion, and A/D trigger synchronization - all synchronized to a common clock domain derived from the main PLL or sub-clock.

FAQ

What is the maximum operating frequency of the Arm Cortex-M3 core in CY9BF514NPMC-G-JNE1?

The CY9BF514NPMC-G-JNE1 supports up to 144 MHz CPU operation using the main PLL with an external 4–48 MHz crystal or clock source. At frequencies above 72 MHz, the Flash Accelerator ensures zero-wait-state instruction fetch via prefetch and trace buffer management, maintaining full performance without software stalls.

Does CY9BF514NPMC-G-JNE1 support USB device and host modes simultaneously?

Yes - the integrated USB 2.0 Full-Speed controller supports concurrent device and host operation through separate endpoint buffers and dual-mode PHY control logic. Device mode supports up to 6 endpoints (including 256-byte EP1), while host mode handles up to two connected devices with automatic enumeration and token handshake handling.

How many CAN interfaces does CY9BF514NPMC-G-JNE1 include, and what protocol versions are supported?

CY9BF514NPMC-G-JNE1 integrates two independent CAN 2.0A/B-compliant controllers, each supporting bit rates up to 1 Mbps and featuring 32-message RAM buffers with hardware acceptance filtering. Both channels support standard and extended frame formats and are electrically isolated from each other to enable redundant network topologies.

Is the CY9BF514NPMC-G-JNE1 pin-compatible with other FM3 series MCUs?

No - CY9BF514NPMC-G-JNE1 uses a 120-pin LQFP package with a unique pin assignment optimized for its peripheral mix (e.g., dual CAN, USB, QPRC). While other FM3 devices share architectural similarities, pin mapping differs across sub-families; refer to the "Pin Assignments" section of Document 002-08541 Rev. *E for exact signal locations.
