Infineon Technologies CY9BF514RPMC-G-JNE2

Overview

CY9BF514RPMC-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 2.0A/B interfaces (up to 1 Mbps), and USB 2.0 Full-Speed device/host capability - deployed in motor control, industrial automation, and automotive body electronics.

For engineers reviewing the CY9BF514RPMC-G-JNE2 datasheet, CY9BF514RPMC-G-JNE2 pinout, CY9BF514RPMC-G-JNE2 application, or CY9BF514RPMC-G-JNE2 equivalent, key selection criteria include integrated motor control timers (PPG, PWM, QPRC), 12-bit ADC with 1.0 μs conversion @ 5 V, 8-channel DMA, real-time clock with leap-year support, and dual low-power watchdogs with independent clock sources.

Technical Context

This MCU implements an Arm Cortex-M3 r2p1 core operating up to 144 MHz with MPU and NVIC supporting 48 peripheral interrupts across 16 priority levels. It integrates two independent Flash banks (MainFlash with accelerator + trace buffer; WorkFlash with configurable wait states) and dual-bus SRAM architecture (SRAM0 on I/D-code bus, SRAM1 on system bus).

The peripheral set includes three multi-function timer units for motor control (PWM, dead-time insertion, DTIF interrupt), three QPRC channels for encoder position sensing, and a dedicated CRC accelerator supporting CCITT CRC16 and IEEE-802.3 CRC32 - all synchronized via five clock sources including main PLL, sub-clock (32.768 kHz), and dual CR oscillators.

FAQ

What is the maximum operating frequency of the Arm Cortex-M3 core in CY9BF514RPMC-G-JNE2?

The CY9BF514RPMC-G-JNE2 supports up to 144 MHz CPU operation using the main PLL with external crystal input. This frequency is achievable with zero wait-state access to MainFlash thanks to the integrated Flash Accelerator System and 16 KB trace buffer, enabling deterministic real-time performance for motor control loops and communication stacks.

Does CY9BF514RPMC-G-JNE2 support USB device and host modes simultaneously?

Yes - the integrated USB 2.0 Full-Speed controller supports concurrent device and host operation. The hardware automatically manages endpoint allocation, token handshake, and device connect/disconnect detection. Up to six endpoints are available in device mode (including double-buffered EP1–EP5), and host mode supports up to 256-byte packet length with automatic IN/OUT token handling.

How does the WorkFlash differ from MainFlash in terms of usage and timing behavior?

WorkFlash (32 KB) is optimized for frequent firmware updates and parameter storage, with configurable wait states: 0-cycle access ≤40 MHz, 2-cycle access at 40–72 MHz, and 4-cycle access >72 MHz. Unlike MainFlash, it shares code protection security but lacks the trace buffer and accelerator - making it ideal for safe dual-bank OTA updates without disrupting main application execution.

Can the QPRC channels operate independently while the CPU is in Stop mode?

No - QPRC counters require the system clock (PCLK) to run and are disabled in Stop mode. However, they remain fully operational in Sleep and Timer low-power modes. For encoder monitoring during deepest sleep, use the dedicated Watch Counter with sub-clock (32.768 kHz) to wake the CPU on event-triggered interrupts, then resume QPRC operation upon wake-up.
