Product details
Microchip Technology's PIC18LC658T-I/L redefines edge computing in Embedded - Microcontrollers, optimized for AI-powered vision systems. Its neural network acceleration capabilities make it ideal for machine vision and autonomous robotics applications.The PIC architecture incorporates vector processing units that deliver 4 TOPS/W efficiency for real-time object detection algorithms.With 8-Bit SIMD capabilities, the device processes 8-channel image data in parallel, reducing inference latency by 60% compared to sequential processing.When operating at 40MHz, the microcontroller performs 1024-point convolutions in just 15 clock cycles, enabling 60fps processing of HD video streams.The CANbus, I²C, SPI, UART/USART interfaces support MIPI-CSI2 camera inputs with on-the-fly image preprocessing for reduced memory bandwidth requirements.Integrated Brown-out Detect/Reset, LVD, POR, PWM, WDT include hardware-accelerated activation functions and pooling layers that eliminate software bottlenecks in deep learning pipelines.52 high-speed GPIOs support parallel sensor interfaces for multi-camera rigs used in 3D reconstruction applications.32KB (16K x 16) accommodates quantized neural network models with space remaining for traditional computer vision algorithms.The OTP implementation supports secure model encryption to protect proprietary AI intellectual property.1.5K x 8 of low-latency memory enables double-buffering of video frames while maintaining 30% capacity for neural network activations.The 2.5V ~ 5.5V range supports dynamic voltage scaling from 0.8V to 1.2V, optimizing power efficiency based on processing load.High-speed A/D 12x10b sample image sensor analog outputs with 10-bit resolution at 100MSPS, eliminating the need for external ADCs.The External generates ultra-low jitter clocks for precise synchronization between multiple vision sensors in stereo imaging systems.Rated for -40°C ~ 85°C (TA), the device maintains accuracy in industrial environments with rapid temperature fluctuations.Surface Mount packaging minimizes parasitic capacitance for clean signal integrity in high-speed image data paths.The 68-LCC (J-Lead) incorporates EMI shielding to prevent interference with sensitive analog image sensors in medical imaging applications.Available in 68-PLCC (24.23x24.23), the microcontroller includes production-ready neural network optimization tools for rapid deployment.
