Product details
Overview
CY9BF114NBGL-GE1 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 watchdog timers, RTC, QPRC, and hardware CRC acceleration.
For engineers reviewing the CY9BF114NBGL-GE1 datasheet, CY9BF114NBGL-GE1 pinout, CY9BF114NBGL-GE1 application, or CY9BF114NBGL-GE1 equivalent, key selection criteria include its 12-bit ADC (1.0 μs conversion @5 V), eight-channel DMA, LIN 2.1 support, 103 GPIOs in 120-pin LQFP, and dual power supply monitoring (LVD1/LVD2) for robust real-time control.
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 Flash architecture separates code execution (MainFlash) from data logging or firmware updates (WorkFlash), each with distinct wait-state behavior and shared security protection.
The peripheral set is optimized for motion control: three multi-function timers with PWM, dead-time insertion, and A/D activation; three QPRC channels for encoder position tracking; and dedicated motor control interfaces including CSIO, UART with hardware flow control (CTS/RTS on ch.4), and LIN master/slave operation with configurable break field (13–16 bit).
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 dual-bank firmware update and runtime parameter storage |
| 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-resolution analog sensing for current/voltage feedback in motor drives |
| Timers | 8× Base Timers (PWM/PPG/reload/PWC), 3× Multi-function Timers (input capture/output compare/waveform gen) - delivers precise timing for 3-phase motor commutation and fault detection |
| Communication | Up to 8 serial channels (UART/CSIO/I²C/LIN), LIN 2.1 compliant - enables distributed control networks with diagnostic messaging and synchronization |
| Power Supply | 2.7 V to 5.5 V operating range - allows direct interface with 3.3 V logic and 5 V sensors/actuators without level-shifting |
Pinout & Package
CY9BF114NBGL-GE1 is housed in a 120-pin LQFP (14 mm × 14 mm, 0.4 mm pitch) package 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 VCC pins (VCC1/VCC2) and multiple VSS pins ensure stable core/peripheral voltage distribution and noise suppression |
| XTAL / EXTAL | Main clock oscillator input/output | Supports 4–48 MHz crystal or external clock source for precise timing control of CPU and peripherals |
| OSC32K / OSC32KOUT | Sub-clock oscillator input/output | Connects to 32.768 kHz crystal for RTC and low-power wake-up timer operation |
| PA0–PA15, PB0–PB15, etc. | General-purpose I/O with peripheral multiplexing | 103 total GPIOs; each pin supports pull-up, direct read, and function relocation - simplifies board design for varying interface requirements |
| AD0–AD15 | Analog input channels | 16 dedicated ADC input pins mapped to internal 12-bit SAR converter - enables simultaneous sampling of motor phase currents and temperature sensors |
| MTIOA0–MTIOB2 | Motor timer I/O (QPRC, PWM) | Three QPRC channels (AIN/BIN/ZIN) and six PWM output pins - directly drive encoder interfaces and gate drivers in BLDC/PMSM systems |
Key Features
| Feature | Design Value |
|---|---|
| Flash Accelerator with 16 KB trace buffer | Enables zero-wait-state Flash access at ≤72 MHz and near-zero latency above 72 MHz - critical for deterministic ISR execution in motor control loops |
| Dual watchdog system (HW + SW) | Hardware watchdog runs on 100 kHz internal CR oscillator - remains active in all power modes except Stop, ensuring fail-safe recovery during deep sleep |
| Real-time clock with leap-year support | Tracks full calendar (Year/Month/Day/Hour/Minute/Second/Weekday) with programmable alarms - enables time-stamped event logging and scheduled maintenance triggers |
| CRC accelerator (CRC16/32) | Offloads CCITT CRC16 and IEEE-802.3 CRC32 computation from CPU - improves firmware update integrity verification speed by >10× vs. software implementation |
| Port relocate function | Allows dynamic assignment of peripheral functions (e.g., UART0, LIN1, I²C0) to any compatible GPIO group - eliminates fixed pin constraints in dense PCB layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 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, QPRC not available | Lacks native LIN 2.1 and quadrature counter - requires external transceivers and FPGA logic for motor position tracking | Select when floating-point math or DSP instructions are required, but accept added BOM cost and complexity for motor control |
| RA4M2 Group (R7FA4M2AD3CFM) | ARM Cortex-M33 core, 100 MHz, 512 KB Flash, 128 KB SRAM, no WorkFlash, no QPRC | Higher security (TrustZone), larger RAM, but missing dedicated motor control peripherals like DTIF and PPG timers | Prefer for secure IoT edge nodes where safety certification matters more than real-time motor timing precision |
Compared with STM32F303VCT6 and RA4M2, CY9BF114NBGL-GE1 uniquely combines LIN 2.1 PHY support, three QPRC channels, and motor-specific timers in a single chip - reducing component count and PCB area for cost-sensitive industrial drives.

FAQ
What is the maximum operating frequency and how is it achieved?
The CY9BF114NBGL-GE1 achieves up to 144 MHz using its main PLL, which accepts input from either an external 4–48 MHz crystal or the internal 4 MHz CR oscillator. The Flash Accelerator with 16 KB trace buffer eliminates wait states up to 72 MHz and maintains near-zero latency above that frequency, enabling full-speed instruction execution without performance penalty.
Does this MCU support LIN communication without external transceivers?
Yes - the CY9BF114NBGL-GE1 includes full LIN 2.1 protocol stack support in hardware, including configurable break field (13–16 bit), break delimiter (1–4 bit), and automatic checksum generation. However, a physical-layer LIN transceiver (e.g., TLE7259-3GE) is still required for bus-level signaling and ESD protection.
How does the dual Flash architecture improve firmware update reliability?
The separation of MainFlash (512 KB, executable code) and WorkFlash (32 KB, non-volatile data/log storage) allows atomic firmware updates: new code is written to MainFlash while running from WorkFlash-resident bootloader, with hardware security locking preventing partial writes. This eliminates risk of bricking during field updates.
What power modes are supported and which peripherals remain active in each?
CY9BF114NBGL-GE1 supports Sleep, Timer, and Stop modes. In Sleep mode, CPU halts but all peripherals (including RTC, QPRC, and LIN) continue operating. In Timer mode, only the sub-clock domain (RTC, Watch Counter) stays active. In Stop mode, only the hardware watchdog (clocked by 100 kHz CR oscillator) remains functional - enabling ultra-low-power wake-up capability.
