Microchip PIC18F47Q10-I/PT: A Comprehensive Technical Overview
The Microchip PIC18F47Q10-I/PT represents a significant evolution within the renowned PIC18 family of 8-bit microcontrollers (MCUs). Engineered for a broad spectrum of embedded control applications, this device combines robust core performance with a rich set of peripheral integration, all while emphasizing power efficiency and design security. This overview delves into the key technical attributes that make this MCU a compelling choice for engineers.
At the heart of the PIC18F47Q10 lies the enhanced PIC18 core with a hardware multiplier, capable of operating at speeds up to 64 MHz. This translates to a performance of 16 million instructions per second (MIPS), providing ample computational power for complex control algorithms and data processing tasks typical in industrial, automotive, and consumer applications.
A standout feature of this MCU is its substantial and versatile memory architecture. It is equipped with 128 KB of Flash program memory and 8 KB of RAM, facilitating the development of sophisticated applications. The Flash memory supports self-read/write (Read-While-Write) capability, enabling robust bootloader and Over-The-Air (OTA) firmware update implementations without requiring an external memory component.
The peripheral set is exceptionally comprehensive, designed to minimize external component count and simplify system design. Key integrated peripherals include:
Analog-to-Digital Converter (ADC) with Computation (ADCC): A 12-bit ADC with a built-in computation engine that can perform averaging, filtering, and comparison in hardware, offloading the CPU and saving power.
Multiple Communication Interfaces: It features up to 6 UARTs, 3 SPI, and 3 I2C modules, providing extensive connectivity options for sensors, displays, wireless modules, and other peripherals.
Core Independent Peripherals (CIPs): These are hardware-based modules like Timers, CCP, and PWM that operate without constant CPU intervention. This allows for the creation of deterministic control loops and system functions that run even in low-power sleep modes, drastically reducing overall power consumption.
Hardware Security: The MCU incorporates Programmable Code Protection and a Hardware Crypto Engine with AES and 3DES algorithms, safeguarding intellectual property and ensuring secure communication.
The device is offered in a 44-pin TQFP (Thin Quad Flat Pack) package, denoted by the /PT suffix in its part number. This package is suitable for space-constrained applications requiring a moderate number of I/O pins. The -I suffix indicates an industrial temperature range (-40°C to +85°C), making it suitable for harsh environments.
ICGOODFIND: The PIC18F47Q10-I/PT is a highly integrated and capable 8-bit microcontroller from Microchip. Its blend of high performance, large memory, advanced analog, numerous communication options, and robust security features positions it as an excellent solution for developers seeking to create efficient, secure, and connected embedded systems without stepping into the 32-bit arena.
