Infineon Technologies CY9BF515RPMC-G-JNE2

Overview

CY9BF515RPMC-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 (1 Mbps), and USB 2.0 Full-Speed device/host support - designed for motor control, industrial automation, and embedded real-time systems requiring integrated timing, analog conversion, and communication peripherals.

For engineers reviewing the CY9BF515RPMC-G-JNE2 datasheet, CY9BF515RPMC-G-JNE2 pinout, CY9BF515RPMC-G-JNE2 application, or CY9BF515RPMC-G-JNE2 equivalent, key selection criteria include its 144 MHz max CPU frequency, on-chip MPU and NVIC with 48 peripheral interrupts, 12-bit ADC (1.0 μs @ 5 V), QPRC encoder interface, and dual power supply (VCC: 2.7–5.5 V, USBVCC: 3.0–3.6 V).

Technical Context

This MCU implements a tightly coupled Arm Cortex-M3 r2p1 core with Memory Protection Unit (MPU) and integrated Nested Vectored Interrupt Controller (NVIC), enabling deterministic real-time response in safety-critical embedded environments. It supports dynamic clock switching among five sources - including 4–48 MHz main oscillator, 32.768 kHz sub-clock, and internal CR oscillators - with Clock Supervisor (CSV) monitoring external clock failure or frequency anomaly.

The peripheral architecture features three independent timer subsystems: Base Timers (8 channels, supporting PWM/PPG/reload modes), Multi-function Timers (3 units with input capture, output compare, A/D activation, and DTIF emergency stop), and Quadrature Position/Revolution Counters (3 channels with 16-bit position/revolution counters and configurable AIN/BIN/ZIN edge detection) - all optimized for closed-loop motor control and motion feedback.

Key Specifications

FAQ

What debug interfaces does CY9BF515RPMC-G-JNE2 support?

It supports Serial Wire JTAG Debug Port (SWJ-DP) with Embedded Trace Macrocell (ETM) for full instruction trace and real-time debugging. No SWD-only or cJTAG variants - full JTAG boundary scan and SWD are both enabled via the same 5-pin debug header (TCK, TMS, TDI, TDO, nTRST). The ETM provides cycle-accurate program flow visibility without halting CPU execution.

Does CY9BF515RPMC-G-JNE2 support USB device and host simultaneously?

No - USB device and host modes are mutually exclusive and configured at boot via the USBMODE register. The hardware shares the same PHY and endpoint resources; switching between modes requires full USB controller reinitialization and cannot occur dynamically during runtime without resetting the USB subsystem.

How is flash security implemented on this MCU?

Code protection is enforced through lock bits in the Flash Configuration Area (FCA), preventing read-out of MainFlash and WorkFlash contents via debug interface or bootloader. Security is hardware-enforced: once locked, only a full chip erase (which clears all protected memory) can restore access - no backdoor keys or undocumented unlock sequences exist per Infineon's FM3 Security Manual Rev. *B.

What is the maximum operating temperature range for CY9BF515RPMC-G-JNE2?

The device is rated for industrial temperature range: –40 °C to +85 °C ambient, verified per JEDEC JESD22-A104. This applies to all speed grades and package variants, including the CY9BF515RPMC-G-JNE2 LQFP-120. No extended or automotive grade variant exists for this specific part number.
