Microchip PIC18F67J60T-I/PT: An Integrated 8-Bit Microcontroller with Ethernet Connectivity
The Microchip PIC18F67J60T-I/PT represents a significant integration of processing power and connectivity within a single chip. This 8-bit microcontroller (MCU) is engineered for applications requiring embedded Ethernet communication, combining a robust microcontroller core with a full-featured Ethernet controller on a single piece of silicon. This integration simplifies design, reduces component count, and lowers overall system cost for networked devices.
At its heart lies a high-performance PIC18 core, capable of operating at up to 41.67 MHz. It is supported by a substantial 128 KB of self-programmable Flash memory and 3,808 bytes of RAM, providing ample space for both application code and the sophisticated TCP/IP protocol stack necessary for network operations. A key feature of this MCU is its integrated 10BASE-T/100BASE-TX Ethernet MAC and PHY. This eliminates the need for an external network interface controller (NIC), making it an ideal solution for creating compact, efficient connected devices.
The integrated IEEE 802.3 compliant Ethernet module handles all the complex requirements of Ethernet communication, including packet framing, CSMA/CD logic, and automatic CRC generation and checking. It supports full- and half-duplex operation, automatic polarity detection and correction, and link integrity functions. This allows designers to implement a wide range of network protocols—such as TCP, UDP, IP, ARP, ICMP, HTTP, and DHCP—directly on the microcontroller, enabling it to act as a web server or a client on a network.
Beyond its networking prowess, the MCU is equipped with a rich set of peripherals, making it a versatile choice for various embedded control applications. It features a 10-bit Analog-to-Digital Converter (ADC) with up to 13 channels, multiple timers, capture/compare/PWM modules, and serial communication interfaces like USART, SPI, and I²C. These features allow it to interface with a vast array of sensors, actuators, and other components, processing data and then communicating the results over a local network or the internet.
Housed in a 64-pin TQFP package, the PIC18F67J60T is designed for industrial temperature ranges (-40°C to +85°C), ensuring reliable operation in harsh environments. Its typical applications are vast, including industrial control and monitoring systems, building automation, networked sensors, remote data loggers, and smart energy management systems.
ICGOODFIND: The Microchip PIC18F67J60T-I/PT stands out as a highly integrated, cost-effective solution for developers looking to add Ethernet connectivity to 8-bit embedded systems. Its single-chip design, combining a capable MCU with a full Ethernet stack, significantly accelerates development and reduces the bill of materials for a wide range of connected IoT and industrial products.
