MCHPPIC16F1454-I/SL
Overview
The PIC16F1454-I/SL is a high-performance 8-bit microcontroller featuring eXtreme Low Power (XLP) technology and integrated USB 2.0 connectivity. This device is unique for its Crystal-free USB operation, utilizing an internal oscillator with active-clock tuning from the USB host to eliminate the need for external timing components. It operates at up to 48MHz and provides 8KB of Flash memory in a compact 14-pin SOIC package.
Why Choose This Part
The primary advantage is the reduction in BOM cost and PCB footprint achieved through its crystal-free USB architecture. Its eXtreme Low Power (XLP) performance, featuring 30 uA/MHz active current at 1.8V, makes it ideal for energy-sensitive designs. Additionally, the device supports a wide operating voltage from 2.3V to 5.5V and includes 5V tolerant I/O pins for simplified interfacing.
Applications
Key Specifications
Getting Started
Development is supported by the MPLAB X IDE and the XC8 C Compiler. For hardware evaluation, the MPLAB PICkit 4 or MPLAB Snap in-circuit programmers can be used via the ICSP interface. Microchip provides the MLA (Microchip Libraries for Applications) which includes pre-verified USB stacks for HID, CDC, and Custom classes specifically for this PIC16F family.
