54-00005

Overview

The Interlink Electronics model 54-00005 is a 4-zone USB microcontroller based on the Microchip PIC18F14K50. It serves as the processing unit for the MicroJoystick pointing system, translating simultaneous 360-degree directional and speed inputs from Force Sensing Resistor (FSR) sensors into digital signals. The device supports standard USB connectivity and interfaces with the four FSR zones (North, South, East, West) to enable intuitive cursor control.

Feature Summary

• Processes simultaneous multi-directional input from four pressure-sensitive zones
• Provides direct USB interface capability for host communication
• Enables dynamic speed control by interpreting varying applied pressure levels

Applications

• OEM pointing systems requiring precise cursor movement
• Human-machine interface solutions for embedded devices
• Hardware development kits for joystick integration testing

Procurement Notes

Verify that the component matches the specific Microchip PIC18F14K50 designation within the Interlink 54-series nomenclature. Confirm compatibility with the intended MicroJoystick sensor array and ensure the firmware configuration aligns with the required USB HID standards before deployment.

Selection Notes

Select this controller when integrating the MicroJoystick into a USB-based application. Ensure the design accommodates the necessary voltage regulation and signal conditioning for the connected FSR sensors. Verify that the target system supports the specific USB protocol requirements defined by the Microchip architecture.

Part Context

This component functions as the central processing unit within the MicroJoystick ecosystem. It bridges the analog outputs of the FSR sensors with the digital requirements of a USB host, allowing manufacturers to implement high-precision pointing controls without developing custom silicon or complex driver stacks.

Replacement Considerations

No public substitute part numbers are documented. Replacement requires matching the Microchip PIC18F14K50 specifications and ensuring identical firmware logic for the specific Interlink sensor mapping.
