Supply/Recycle Microchip PIC18F57Q84-I/PT Low-Power High-Performance MCU With XLP Technology

Within the embedded systems domain, balancing low power consumption with high performance remains a core design imperative. This is particularly true for battery-powered or power-sensitive applications such as industrial control, automotive electronics, and IoT endpoints, where a device's energy efficiency directly determines product endurance and operational stability. Shenzhen Mingjiada Electronics Co., Ltd. supplies and recycles Microchip's PIC18F57Q84-I/PT microcontroller. Equipped with nanoWatt XLP (Ultra Low Power) technology, it combines exceptional computational performance with a rich array of peripherals, making it an optimal solution balancing energy efficiency and functionality. This provides robust support for embedded designs in complex scenarios.

【PIC18F57Q84-I/PT XLP Technology Core: Redefining Low-Power Operation Paradigms】

The PIC18F57Q84-I/PT derives its competitive edge from nanoWatt XLP low-power technology. This represents a comprehensive upgrade over traditional nano-watt-level power solutions, achieving minimal power consumption across diverse operating states through hardware architecture optimisation and multi-mode power management strategies. Its core design philosophy centres on demand-driven power allocation. Through software-configurable multi-mode operation, the device transitions to low-power states during task intervals while retaining wake-up capability for critical functions, achieving a dynamic equilibrium between energy efficiency and responsiveness.

The PIC18F57Q84-I/PT device offers four core operating modes: Deep Sleep, Sleep, Idle, and Normal Operation, covering the full spectrum of requirements from extreme energy efficiency to high-performance computing. Deep sleep mode, as the lowest power state, achieves typical power consumption down to the nanowatt range by cutting power to the core and most peripherals, while retaining only critical wake-up sources such as the real-time clock (RTCC), watchdog timer (WDT), and external interrupts. This significantly extends the operational lifespan of battery-powered devices. Sleep mode, meanwhile, deactivates the main CPU clock while preserving RAM and register states. It supports wake-up via peripherals such as ADCs, comparators, and serial communication modules, offering short wake-up latency without requiring a reset. This makes it suitable for low-power scenarios involving frequent interactions. Furthermore, the Peripheral Module Disable (PMD) function selectively cuts power to idle peripherals, further optimising active-mode power consumption by activating only essential hardware during specific tasks.
