Product details
Overview
CY9BF112NPMC-G-JNE1 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 512 KB MainFlash, 32 KB WorkFlash, 64 KB SRAM, 144 MHz max CPU frequency, and integrated motor control peripherals including QPRC, multi-function timers, and LIN/UART/I²C/CSIO interfaces. It targets embedded motor control systems requiring real-time position sensing, PWM generation, and fault-safe operation.
For engineers reviewing the CY9BF112NPMC-G-JNE1 datasheet, CY9BF112NPMC-G-JNE1 pinout, CY9BF112NPMC-G-JNE1 application, or CY9BF112NPMC-G-JNE1 equivalent, key selection criteria include Flash/SRAM partitioning, 12-bit ADC conversion time (1.0 μs @ 5 V), LIN 2.1 compliance, dual watchdog architecture (hardware + software), and 5 V-tolerant I/O support on selected pins.
Technical Context
This MCU implements a deterministic real-time execution environment via its Arm Cortex-M3 r2p1 core with Memory Protection Unit (MPU) and NVIC supporting 48 peripheral interrupts across 16 priority levels. Its dual Flash architecture separates application code (MainFlash) from configuration/data (WorkFlash), each with independent security and timing characteristics.
The peripheral set is optimized for motion control: three QPRC channels accept A/B/Z encoder inputs with configurable edge detection; eight base timers support 16-/32-bit PWM, PPG, and PWC modes; and the multi-function timer includes dedicated A/D activation compare and DTIF (motor emergency stop) interrupt capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M3 r2p1, up to 144 MHz - enables deterministic real-time task scheduling with low-latency interrupt response |
| Flash Memory | 512 KB MainFlash + 32 KB WorkFlash - supports secure firmware updates and runtime parameter storage with independent wait-state control |
| SRAM | 64 KB total (32 KB SRAM0 + 32 KB SRAM1) - SRAM0 connects to I/D buses for zero-wait instruction/data access; SRAM1 serves system bus peripherals |
| ADC | 12-bit SAR, 16-channel, 1.0 μs conversion @ 5 V - provides high-speed analog feedback for closed-loop motor current/voltage sensing |
| Timers | 8× base timers (PWM/PPG/PWC), 3× multi-function timers (with A/D activation & DTIF), 3× QPRC - delivers synchronized PWM, encoder position capture, and hardware-triggered ADC sampling |
| Communication | LIN 2.1, UART, I²C (100/400 kbps), CSIO - enables interoperability with automotive body electronics and industrial sensor networks |
| Power Supply | 2.7 V to 5.5 V - allows direct interface with 3.3 V logic and 5 V analog/sensor domains without level-shifting |
Pinout & Package
The CY9BF112NPMC-G-JNE1 is housed in a 120-pin LQFP package (14 mm × 14 mm, 0.4 mm pitch) with exposed thermal pad. Pin functions are fully relocatable via port mapping registers, enabling flexible PCB layout and signal routing optimization.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply / Ground | Dual power domains: VCC1 (core/analog), VCC2 (I/O), each with dedicated VSS pairs - ensures noise isolation between digital logic and analog peripherals |
| XTAL1 / XTAL2 | Main oscillator input/output | Supports 4–48 MHz crystal or external clock - primary timing source for PLL and system clock generation |
| OSC32K / OSC32KOUT | 32.768 kHz sub-clock input/output | Drives RTC and wake-up timer independently of main clock - enables accurate timekeeping and low-power sleep mode recovery |
| AIN0–AIN2 / BIN0–BIN2 / ZIN0–ZIN2 | Quadrature encoder inputs | Three independent QPRC channels with configurable edge sensitivity - directly interfaces incremental encoders for position/speed feedback in BLDC/PMSM drives |
| MTIOC0A–MTIOC7B | Motor timer output compare | Eight complementary PWM outputs with programmable dead-time insertion - generates gate drive signals for 3-phase inverter bridges |
| ADTRG0–ADTRG2 | ADC trigger inputs | Hardware-synchronized sampling initiation from timer events - eliminates software jitter in current-sensing loops |
Key Features
| Feature | Design Value |
|---|---|
| Memory Protection Unit (MPU) | Enforces memory access permissions per region - prevents accidental or malicious corruption of critical code/data sections during runtime |
| Dual Watchdog Architecture | Independent hardware (CR oscillator-clocked) and software watchdogs - ensures fail-safe reset even during deep sleep or clock failure |
| Port Relocation Function | Runtime remapping of peripheral functions to alternate GPIO pins - simplifies board layout and enables pin reuse across product variants |
| CRC Accelerator | Hardware CCITT CRC16 and IEEE-802.3 CRC32 - offloads integrity checking from CPU for firmware OTA updates and sensor data transmission |
| Low-Voltage Detection (LVD) | Two-stage monitoring (LVD1 interrupt, LVD2 reset) at user-configurable thresholds - provides graceful shutdown or error logging before brownout |

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, 256 KB Flash, no integrated LIN PHY, requires external transceiver | Lacks native LIN 2.1 support; relies on software stack and external IC for physical layer | Preferred when floating-point math acceleration is required and LIN is implemented via external transceiver |
| RA4M2 (R7FA4M2AD3CFM) | ARM Cortex-M33 core, 100 MHz, 512 KB Flash, 128 KB SRAM, integrated CAN FD but no LIN | Offers CAN FD instead of LIN; higher SRAM but lacks QPRC hardware blocks | Selected for CAN-based motor networks where encoder position is handled via SPI-connected ASICs |
Compared with STM32F303VCT6 and RA4M2, the CY9BF112NPMC-G-JNE1 uniquely integrates LIN 2.1 PHY, QPRC, and dual watchdogs in a single die - reducing component count and latency in cost-sensitive, encoder-driven motor systems.

FAQ
What is the maximum operating frequency and how is it achieved?
The CY9BF112NPMC-G-JNE1 achieves up to 144 MHz CPU frequency using its internal Main PLL, which accepts input from either the 4–48 MHz main crystal oscillator or the 4 MHz high-speed internal CR oscillator. The Flash Accelerator System eliminates wait states up to 72 MHz and maintains equivalent performance above that frequency through trace buffer and prefetch logic.
Does this MCU support hardware LIN communication without external components?
Yes. The CY9BF112NPMC-G-JNE1 includes a fully integrated LIN 2.1 controller with built-in break field generation (13–16 bit), delimiter control (1–4 bit), and automatic checksum calculation. It operates in both master and slave modes and requires only an external LIN transceiver for physical layer compliance - no software protocol stack is needed for basic frame transmission/reception.
How does the dual Flash architecture improve firmware update reliability?
The separation of 512 KB MainFlash (for application code) and 32 KB WorkFlash (for configuration, calibration data, and firmware update staging) enables atomic over-the-air updates. While running from MainFlash, new firmware can be validated in WorkFlash before swapping execution vectors - preventing bricking during power loss or corruption.
What power modes are supported 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 2.5 μA. This mode retains SRAM content and allows wake-up via external interrupt, RTC alarm, or watchdog timeout - ideal for battery-backed applications requiring multi-day standby.
