Microchip PIC18F4680-I/PT: A Comprehensive Technical Overview
The Microchip PIC18F4680-I/PT stands as a robust and versatile 8-bit microcontroller within Microchip's extensive PIC18 family. Engineered for applications demanding high performance, integrated peripherals, and connectivity, this MCU is a cornerstone for complex embedded designs in automotive, industrial, and advanced consumer electronics.
Housed in a 44-pin TQFP package, the device is built on an enhanced PIC18 architecture with a 16-bit wide instruction set and an 8-bit data path. Its core operates at speeds up to 40 MHz, executing most instructions in a single clock cycle, yielding a performance of up to 10 MIPS. This processing power is sufficient for handling substantial computational tasks and complex control algorithms.
A significant feature of the PIC18F4680 is its substantial memory configuration. It boasts 96 KB of Flash program memory and 3328 bytes of RAM, providing ample space for sophisticated application code and data handling. Furthermore, it includes 1024 bytes of EEPROM data memory, offering reliable non-volatile storage for critical data without requiring external components.
The peripheral set integrated into this MCU is exceptionally comprehensive. It features two enhanced Capture/Compare/PWM (ECCP) modules for advanced motor control and power conversion applications. For connectivity, it is equipped with an Addressable USART (AUSART) for LIN bus support, a Master Synchronous Serial Port (MSSP) that can operate in both SPI and I²C modes, and a Controller Area Network (CAN) 2.0B module. This integrated CAN bus controller is particularly critical for automotive and industrial network applications, eliminating the need for an external controller chip.
Analog capabilities are addressed with a 10-bit Analog-to-Digital Converter (ADC) with up to 13 input channels, allowing for precise measurement of multiple analog sensors. The inclusion of a comparator module adds further flexibility for real-time analog signal monitoring.
Operating voltage ranges from 2.0V to 5.5V, making it suitable for both low-power and mainstream applications. Its extended temperature range (-40°C to +85°C) ensures reliable operation in harsh environmental conditions.
ICGOODFIND: The PIC18F4680-I/PT is a high-integration 8-bit MCU distinguished by its large memory footprint, extensive peripheral set including a critical integrated CAN controller, and robust operating characteristics. It represents an optimal solution for designers seeking a single-chip answer for complex networked control systems without migrating to a 16- or 32-bit architecture.
