Product details
Overview
CY9BF314RPMC-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, USB 2.0 Full-Speed device/host interface, and integrated motor control timers. It operates up to 144 MHz, supports LIN 2.1, I²C, UART, CSIO, and features a Memory Protection Unit (MPU) for embedded safety-critical motor drive and industrial automation systems.
For engineers reviewing the CY9BF314RPMC-G-JNE2 datasheet, CY9BF314RPMC-G-JNE2 pinout, CY9BF314RPMC-G-JNE2 application, or CY9BF314RPMC-G-JNE2 equivalent, key selection criteria include Flash/SRAM partitioning, dual USB mode support, 12-bit ADC with FIFO, QPRC for encoder feedback, and 5 V-tolerant GPIOs in 120-pin LQFP package.
Technical Context
This MCU implements a tightly coupled Arm Cortex-M3 r2p1 core with dual-bus SRAM architecture (SRAM0 on I/D-code bus, SRAM1 on system bus), enabling concurrent CPU and DMA access. Its Flash subsystem includes independent MainFlash (512 KB, accelerator-enabled) and WorkFlash (32 KB, wait-state configurable), supporting secure code protection and in-field firmware updates.
The peripheral set targets real-time motion control: three Multi-function Timers provide PWM, dead-time insertion, A/D activation, and DTIF emergency stop; three QPRC units track quadrature encoder position/revolution; and the RTC supports calendar-based wake-up and leap-year compensation - all synchronized via a flexible clock tree with five sources and CSV supervision.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit Arm Cortex-M3 microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F103ZET6 | 72 MHz max, 512 KB Flash, 64 KB SRAM, no native USB host, no QPRC, no LIN | Lacks integrated motor control peripherals; requires external transceivers for LIN/USB host | Prefer when cost-sensitive and USB host/motor encoder features are unnecessary |
| RA4M1 (R7FA4M1AB3CFM) | 48 MHz max, 256 KB Flash, 32 KB SRAM, USB device only, no QPRC, no DTIF | Lower performance and integration; lacks hardware emergency stop and encoder counter blocks | Choose for simpler control tasks where Renesas ecosystem and low-power sleep modes are prioritized |

FAQ
What is the maximum operating frequency and how is it achieved?
The CY9BF314RPMC-G-JNE2 achieves up to 144 MHz via its built-in Main PLL, which multiplies the 4–48 MHz input from the external crystal or oscillator. The Flash Accelerator system eliminates wait states up to 72 MHz and maintains effective zero-wait access above that frequency through prefetch and trace buffer mechanisms, ensuring deterministic instruction execution at full speed.
Does this MCU support USB device and host simultaneously?
No - the USB interface supports device mode and host mode, but not simultaneous operation. The USB controller is a single physical block with configurable endpoints and descriptors; switching between modes requires firmware reinitialization and register reconfiguration. Dual-role operation must be implemented sequentially, not concurrently.
How many independent ADC modules are integrated and what is their resolution?
This MCU integrates three independent 12-bit successive approximation register (SAR) ADC units, supporting up to 16 input channels total. Each unit provides 1.0 μs conversion time at 5 V supply, with configurable priority levels, scanning mode, and dedicated FIFOs (16-step for scan, 4-step for priority) to reduce CPU overhead during high-speed sampling.
Is the 120-pin LQFP package lead-free and RoHS compliant?
Yes - the CY9BF314RPMC-G-JNE2 uses a lead-free, RoHS-compliant 120-pin LQFP package (14 × 14 mm, 0.4 mm pitch). It meets JEDEC J-STD-020D moisture sensitivity level 3 requirements and is qualified for industrial temperature range (−40°C to +85°C) per the official Infineon datasheet Rev. *F.
