Infineon Technologies CY9BF414RPMC-G-JNE2

Overview

CY9BF414RPMC-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 integrated motor control peripherals including QPRC, multi-function timers, and A/D converter with 12-bit resolution and 1.0 μs conversion time at 5 V. It targets embedded motor control systems in industrial automation and automotive subsystems.

For engineers reviewing the CY9BF414RPMC-G-JNE2 datasheet, CY9BF414RPMC-G-JNE2 pinout, CY9BF414RPMC-G-JNE2 application, or CY9BF414RPMC-G-JNE2 equivalent, key selection criteria include real-time motor timing accuracy, dual CAN bus support for distributed control networks, Flash security features, low-voltage detector staging (LVD1/LVD2), and SWJ-DP debug interface compatibility with Arm CoreSight toolchains.

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. Its memory subsystem includes two independent Flash banks (MainFlash with accelerator + trace buffer; WorkFlash with configurable wait states) and dual-bus-connected SRAM (SRAM0 on I/D-code bus, SRAM1 on system bus).

The peripheral set is optimized for deterministic motion control: three QPRC channels for encoder position/revolution counting, eight base timers configurable as PWM/PPG/reload/PWC, three multi-function timer units with DTIF emergency stop interrupt, and dual CAN controllers compliant with ISO 11898-1:2015 with 32 message buffers each.

FAQ

Does CY9BF414RPMC-G-JNE2 support CAN FD?

No. This MCU implements two CAN 2.0A/B controllers compliant with ISO 11898-1:2015, supporting bit rates up to 1 Mbps. It does not include CAN FD protocol logic, frame format handling, or enhanced data field length support. For CAN FD requirements, consider Infineon's newer XMC4000 or AURIX™ families.

What is the maximum operating temperature range for this part?

CY9BF414RPMC-G-JNE2 is rated for industrial temperature range: –40 °C to +85 °C ambient. It meets JEDEC J-STD-020 moisture sensitivity level 3 and is qualified per AEC-Q100 Grade 2 for automotive use when ordered under appropriate part numbering conventions (e.g., -JNE2 suffix indicates extended temp qualification).

Is the WorkFlash memory electrically erasable and reprogrammable during application runtime?

Yes. WorkFlash supports in-application programming (IAP) with sector erase and byte/word write operations. It requires specific unlock sequences and operates under controlled voltage and timing conditions defined in the FM3 Peripheral Manual. Unlike MainFlash, WorkFlash has configurable wait states but shares the same security lock mechanism.

How many independent clock sources does the device provide?

The device provides five clock sources: two external oscillators (main clock 4–48 MHz, sub-clock 32.768 kHz), two internal CR oscillators (high-speed 4 MHz, low-speed 100 kHz), and one main PLL that accepts either external or internal clock input. All are dynamically switchable via software-controlled clock control registers.
