Product details

Overview

CY9BF116RPMC-G-F4FKE1 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller designed for embedded motor control and industrial automation. 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 A/D converters (12-bit, 1.0 µs conversion), eight base timers, and LIN/UART/I²C/CSIO serial interfaces. Used in brushless DC motor drives requiring real-time PWM, position feedback, and fault-safe communication.

For engineers reviewing the CY9BF116RPMC-G-F4FKE1 datasheet, CY9BF116RPMC-G-F4FKE1 pinout, CY9BF116RPMC-G-F4FKE1 application, or CY9BF116RPMC-G-F4FKE1 equivalent, key selection criteria include its dual 12-bit ADC with FIFO support, QPRC for encoder position tracking, hardware watchdog with CR oscillator backup, RTC with leap-year handling, and 103 GPIOs with port relocation in 120-pin LQFP package.

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 enables secure code protection and background reprogramming via WorkFlash while MainFlash executes.

The peripheral set is optimized for motion control: three multi-function timers provide PWM, dead-time insertion, DTIF emergency stop, and A/D-triggered waveform generation; QPRC channels accept quadrature A/B/Z inputs with configurable edge detection and 16-bit position/revolution counters; LIN 2.1 compliance includes programmable break field (13–16 bit) and delimiter (1–4 bit).

Key Specifications

Key Features

Feature	Design Value
Flash Accelerator with 16 KB trace buffer	Enables zero-wait Flash access at ≤72 MHz and near-zero-wait performance up to 144 MHz - eliminates instruction fetch stalls during high-speed motor control loops.
Port Relocation Function	Allows dynamic assignment of peripheral functions (e.g., UART, LIN, QPRC) to alternate GPIO pins - simplifies PCB routing and avoids signal congestion in dense motor control layouts.
Dual Watchdog Timers	Hardware watchdog (CR oscillator-backed) remains active in Sleep/Timer modes; software watchdog offers configurable timeout - ensures fail-safe recovery during brown-out or firmware hang.
Real-time Clock with Leap-Year Logic	Tracks Y/M/D/h/m/s + weekday with automatic leap-year correction and alarm interrupt down to minute granularity - supports time-stamped event logging and scheduled maintenance triggers.
CRC Accelerator (CRC16/32)	Offloads CCITT CRC16 and IEEE-802.3 CRC32 computation from CPU - accelerates firmware image verification and CAN/LIN message integrity checks without cycle penalty.

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, no integrated LIN PHY, single 12-bit ADC (5 MSPS)	Lacks native LIN 2.1 support; requires external transceiver; lower PWM resolution and no QPRC	Choose when floating-point math or higher ADC sampling rate is prioritized over LIN integration and encoder interface.
RA6M3GFP	ARM Cortex-M4, 200 MHz, 1 MB Flash, 384 KB SRAM, integrated CAN FD, no QPRC or LIN	Supports CAN FD for networked systems but lacks dedicated motor timing peripherals (DTIF, MTIOC) and encoder counters	Prefer for gateway or multi-node systems needing CAN connectivity and larger code space, not standalone motor control.

Compared with STM32F303VCT6 and RA6M3GFP, CY9BF116RPMC-G-F4FKE1 uniquely combines LIN 2.1 hardware, QPRC, DTIF, and port relocation in a single 120-pin LQFP - reducing BOM count and PCB area for cost-sensitive, encoder-based motor controllers.

FAQ

What is the maximum operating frequency and how is it achieved?

The CY9BF116RPMC-G-F4FKE1 achieves up to 144 MHz via its Main PLL, which accepts input from either the 4–48 MHz main crystal oscillator or the 4 MHz internal CR oscillator. The Flash Accelerator with 16 KB trace buffer ensures zero-wait instruction fetch up to 72 MHz and near-zero-wait performance beyond that, enabling deterministic real-time execution without pipeline stalls.

Does this MCU support LIN communication without external transceivers?

Yes - the CY9BF116RPMC-G-F4FKE1 includes full LIN 2.1 protocol support in hardware, including programmable break field (13–16 bits) and delimiter (1–4 bits), automatic checksum calculation, and error detection (framing, parity, overrun). However, an external LIN transceiver is still required for physical layer signaling on the bus line.

How does the QPRC interface handle encoder signals?

The QPRC block supports three independent channels (AIN/BIN/ZIN per channel), each with configurable edge detection polarity and filtering. It provides 16-bit position and revolution counters plus two 16-bit compare registers, enabling direct connection to incremental encoders for closed-loop position control without CPU intervention or external counter ICs.

Is the WorkFlash memory suitable for EEPROM emulation?

Yes - the 32 KB WorkFlash is designed for frequent rewrites and supports read-while-write operation. Its 4-cycle wait state above 72 MHz and shared security function with MainFlash make it ideal for EEPROM emulation, storing calibration data, motor profiles, or field-upgradable parameters without disrupting main application execution.
