Key Features
- PIC16 8-bit CMOS core operating up to 4 MHz clock frequency for low-power sequential control
- High-voltage (HV) input tolerance allows direct interfacing with higher voltage signals without external level shifting
- 18-pin SOIC-18 package provides more I/O pins than smaller 14-pin variants for moderately complex control tasks
- Industrial temperature range (-40°C to +85°C) ensures reliable operation in harsh environments
- Pb-free RoHS-compliant construction meets modern environmental compliance requirements
Applications
The PIC16HV540-04I/SO is used in home appliance control, industrial automation panels, and power tool interfaces where the microcontroller must directly sense or control higher-voltage signals without additional level-shifting circuitry. Its 8-bit PIC16 core running at up to 4 MHz handles simple state machine logic, timer-based sequencing, and multi-channel I/O control in low-cost, high-volume embedded designs. The 18-pin SOIC-18 package provides enough I/O lines for moderate peripheral connectivity while keeping PCB footprint and BOM cost minimal.

Frequently Asked Questions
What does the 'HV' designation mean for the PIC16HV540-04I/SO, and why is it useful?
The 'HV' in PIC16HV540 stands for high-voltage input tolerance. This means selected I/O pins can accept input voltages above the standard VDD rail, often up to 12 V or higher, enabling direct connection to higher-voltage sensor outputs or control signals without external voltage dividers or level translators, which reduces component count in industrial and appliance designs.
What is the maximum clock speed of the PIC16HV540-04I/SO, and what tasks does it handle well?
The PIC16HV540-04I/SO supports a maximum clock frequency of 4 MHz, delivering up to 1 MIPS instruction throughput on the PIC16 core. This speed is adequate for timer-based relay control, LED sequencing, keypad scanning, and simple state machine logic in household appliances, motor controls, and low-speed industrial automation equipment.
How many pins does the PIC16HV540-04I/SO have, and what package is it housed in?
The PIC16HV540-04I/SO is housed in an 18-pin SOIC-18 (0.300 inch wide) package, providing up to 16 general-purpose I/O pins after power and ground connections. The standard SOIC-18 footprint is widely supported in PCB layout tools and readily hand-solderable, making it practical for prototyping and low-to-medium volume production runs.
Can the PIC16HV540-04I/SO operate across industrial temperature extremes?
Yes, the 'I' suffix denotes industrial temperature range operation, covering -40°C to +85°C. This allows the PIC16HV540-04I/SO to function reliably in factory automation panels, outdoor enclosures, HVAC controllers, and other environments where ambient temperatures can swing far below and above typical commercial operating limits of 0°C to 70°C.
