Product details
Overview
CY9BF112RPMC-G-JNE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller designed for motor control and industrial embedded systems. It operates up to 144 MHz, integrates 512 KB MainFlash with Flash Accelerator, 32 KB WorkFlash, 64 KB SRAM (split into SRAM0/SRAM1), and features dual 12-bit ADCs (16 channels total), eight base timers, three QPRC channels, and LIN/UART/I²C/CSIO serial interfaces.
For engineers reviewing the CY9BF112RPMC-G-JNE2 datasheet, CY9BF112RPMC-G-JNE2 pinout, CY9BF112RPMC-G-JNE2 application, or CY9BF112RPMC-G-JNE2 equivalent, key selection considerations include its 120-pin LQFP package, 2.7–5.5 V supply range, hardware watchdog with CR oscillator backup, real-time clock with leap-year support, and motor-control-specific peripherals including dead-time insertion and DTIF interrupt.
Technical Context
This MCU implements the Arm Cortex-M3 r2p1 core with Memory Protection Unit (MPU) and NVIC supporting 48 peripheral interrupts across 16 priority levels. Its dual-bank Flash architecture separates executable code (MainFlash) from configuration/data storage (WorkFlash), each with independent security and timing characteristics.
The peripheral set is optimized for real-time motion control: three multi-function timers provide PWM, PPG, input capture, and A/D activation; QPRC units interface directly with quadrature encoders; and the LIN module complies fully with ISO 17987-2:2013 (LIN 2.1), supporting master/slave modes, programmable break field (13–16 bit), and delimiter (1–4 bit).
Key Specifications

| DTIF0–DTIF2 | Motor emergency stop inputs | Direct hardware-triggered interrupt on signal assertion - bypasses software latency for critical safety shutdown |
Key Features
| Feature | Design Value |
|---|---|
| Flash Accelerator with 16 KB trace buffer | Enables zero-wait-state execution at ≤72 MHz and maintains effective bandwidth >72 MHz via prefetch and caching |
| Hardware CRC accelerator (CRC16/CRC32) | Offloads checksum computation from CPU - improves firmware update integrity verification speed by >20× vs. software implementation |
| Dual watchdog system | Independent hardware (CR oscillator) and software watchdogs - ensures fail-safe reset even during clock failure or deep sleep |
| Port relocate function | Allows dynamic remapping of peripheral signals (e.g., UART, LIN) to alternate GPIO pins - increases PCB layout flexibility and design reuse |
| Low-voltage detection (LVD1/LVD2) | LVD1 triggers interrupt for graceful shutdown; LVD2 forces reset - provides tiered response to brown-out conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F303VCT6 | ARM Cortex-M4F core, 72 MHz max, 256 KB Flash, single 12-bit ADC (16 ch), no native LIN | Lacks integrated LIN PHY and QPRC; requires external transceiver and software encoder counting | Prefer when floating-point math or USB device functionality is required over LIN/QPRC integration |
| RA6M3GFP | ARM Cortex-M4, 200 MHz, 1 MB Flash, 384 KB RAM, 2x 12-bit ADCs, CAN FD, no LIN | Offers CAN FD instead of LIN; QPRC available but only two channels; no DTIF hardware interrupt | Choose for higher-performance applications needing CAN FD networking and larger memory, accepting LIN software stack overhead |
Compared with STM32F303VCT6 and RA6M3GFP, CY9BF112RPMC-G-JNE2 delivers superior motor-control integration via hardware LIN 2.1, triple QPRC, and DTIF-reducing BOM cost and firmware complexity in cost-sensitive industrial drives where LIN is mandatory.

FAQ
What is the maximum operating frequency and supported clock sources?
The CY9BF112RPMC-G-JNE2 operates up to 144 MHz using its main PLL, which accepts input from either a 4–48 MHz external crystal or the 4 MHz internal CR oscillator. Additional clock sources include a 32.768 kHz sub-clock for RTC and two internal CR oscillators (100 kHz and 4 MHz), all selectable dynamically via software registers without reset.
Does this MCU support LIN 2.1 physical layer without external components?
No - CY9BF112RPMC-G-JNE2 integrates the LIN protocol controller and data-link layer (compliant with ISO 17987-2:2013), but requires an external LIN transceiver (e.g., TLE7259-3GE) for physical layer signaling. The MCU provides dedicated LIN TX/RX pins and hardware break field generation, reducing firmware overhead versus software-only implementations.
How is Flash security implemented and what protection levels exist?
Code protection is implemented separately for MainFlash and WorkFlash using lock bits that disable read-out, write, and erase operations. Both Flash banks share the same security function: once locked, debug access (SWJ-DP) and external read attempts are blocked, and unlocking requires full chip erase. Security status is retained after power cycle and verified at reset.
What power modes are available and what is the lowest achievable current draw?
The MCU supports Sleep, Timer, and Stop modes. In Stop mode with RTC active and sub-clock running, typical current consumption is 1.2 μA (max 2.5 μA) at 25°C. Wake-up sources include external interrupts, RTC alarm, and QPRC overflow - enabling battery-powered applications with multi-year runtime using coin-cell batteries.
