Linco (Linko Semiconductor) Motor Control MCUs

Linco motor control MCU CPU performance varies by series: (1) LKS03 - 48MHz 32-bit CPU with hardware divide (640ns) and square root (320ns), suitable for simple BLDC control

(2) LKS05/LKS06/LKS07/LKS08 - 96MHz 32-bit CPU with dedicated DSP co-processor, hardware trigonometric functions in 100ns, supports complex FOC algorithms

(3) LKS45 - 192MHz ARM Cortex-M4F with hardware FPU and DSP instructions, supports dual motor + PFC. All CPUs feature single-cycle multiply and hardware divide acceleration for fast motor control loop execution.

Select 48MHz LKS03 for simple applications, 96MHz LKS05/LKS07 for FOC, 192MHz LKS45 for dual motor.

Linco MCUs integrate rich analog peripherals for motor control: (1) PGA (Programmable Gain Amplifier) - instrument-grade fully differential PGA with programmable gain, handles positive/negative signals without bias voltage

(2) ADC - 12-bit to 14-bit resolution, 1Msps to 3Msps sampling rate, dual simultaneous sampling for current measurement

(3) Voltage Reference - 0.5% precision voltage reference across full temperature range

(4) Comparators - multiple high-speed comparators for overcurrent protection and zero-cross detection

(5) Op-amps - integrated operational amplifiers for signal conditioning. These integrated analog peripherals eliminate external components and reduce system cost.

All LKS series include integrated analog front-end. LKS07/LKS08 offer the richest analog peripheral set for complex applications.

Linco motor control MCUs are available in various packages: (1) QFN20 3x3mm - ultra-compact package for LKS03 series, ideal for space-constrained designs like small fans and toys

(2) QFN24/QFN32 - compact packages for LKS05/LKS07 with good thermal performance

(3) QFN48/QFN52 - larger packages for LKS08/LKS45 with more I/O pins and integrated gate drivers

(4) LQFP48/LQFP64 - traditional leaded packages for easy prototyping and manufacturing. All packages support -40°C to +105°C (consumer) or -40°C to +150°C (automotive) operation. QFN packages offer best thermal and electrical performance for motor control applications.

Use QFN20 for compact designs. Use QFN48/QFN52 for high integration with gate drivers. Use LQFP for prototyping.

Linco MCUs support industry-standard development tools: (1) IDEs - Keil MDK-ARM and IAR Embedded Workbench with device packs for all LKS series

(2) Debuggers - J-Link, ULINK, and ST-Link compatible

(3) Development Boards - evaluation kits available for each series with motor power stage and debugging interface

(4) Software Libraries - complete motor control firmware libraries including FOC, BLDC six-step, and stepper control

(5) Code Examples - reference implementations for air conditioner, washing machine, power tool, and fan applications

(6) Documentation - comprehensive datasheets, user manuals, and application notes. Linco also provides technical training and hands-on workshops.

Use Keil or IAR for development. Order Linco evaluation kits through LiTong for quick prototyping.

Linco MCUs integrate comprehensive motor protection features: (1) Overcurrent Protection - fast analog comparators with hardware shutdown in microseconds

(2) Overvoltage/Undervoltage Protection - programmable voltage monitoring for system safety

(3) Overtemperature Protection - internal temperature sensor with configurable thresholds

(4) Stall Detection - software algorithms detect motor stall and trigger protection

(5) Open Phase Detection - identifies disconnected motor phases

(6) Hardware Fault Input - dedicated pins for external fault signals

(7) Watchdog Timer - system reset on software malfunction. These protection features ensure safe and reliable motor operation in all conditions.

All LKS series include comprehensive protection. Configure protection thresholds based on your motor and application requirements.
