Key Features
- 8-bit PIC16 core running at up to 4 MHz with EPROM program memory for field-reprogrammable firmware updates
- High-voltage (HV) capable supply range extends operation beyond standard 5 V CMOS logic for industrial sensor interfaces
- 18-pin SOIC-18 package enables SMT pick-and-place assembly on compact control boards without through-hole tooling
- No ADC overhead keeps die area and price minimal for pure digital or comparator-based control tasks
Applications
PIC16HV540-04/SO targets low-complexity digital control tasks such as relay sequencers, motor commutation timers, and industrial keypad decoders that benefit from EPROM re-programmability during prototyping. Its high-voltage supply tolerance makes it suitable for 12 V or 15 V powered embedded controllers where a regulated 5 V rail is unavailable. The SOIC-18 footprint integrates cleanly into cost-sensitive consumer appliance and building automation PCBs.

Frequently Asked Questions
What maximum clock frequency does PIC16HV540-04/SO support, and how does that affect instruction throughput?
PIC16HV540-04/SO operates at a maximum clock of 4 MHz. Because the PIC16 architecture executes most instructions in a single 4-cycle machine cycle, this yields a peak throughput of 1 MIPS, sufficient for low-speed control loops, debounce routines, and timer-based PWM on 8-bit data paths.
For which industrial supply voltages is the HV designation in PIC16HV540-04/SO significant?
The 'HV' designation indicates the device tolerates supply voltages above the standard 5 V range, enabling direct operation from unregulated 12 V or higher rails that are common in automotive body electronics, HVAC controllers, and industrial sensor boards, eliminating the need for a dedicated low-dropout regulator in some designs.
How does the 18-pin SOIC-18 package of PIC16HV540-04/SO compare to a DIP-18 for a new SMT design?
The SOIC-18 package has a body of approximately 11.6 mm × 7.5 mm with 1.27 mm pitch leads, occupying roughly 40% less board area than the DIP-18 at 2.54 mm pitch. SMT placement eliminates the need for through-hole drilling, reducing PCB fabrication cost and enabling double-sided component placement on high-density boards.
Is PIC16HV540-04/SO a suitable lower-cost alternative to PIC16F628A for a simple relay-control application?
PIC16HV540-04/SO uses EPROM memory and lacks the internal RC oscillator and comparator peripherals found in PIC16F628A. For a relay-control design that only needs 8-bit I/O, a few timers, and a 4 MHz crystal, PIC16HV540-04/SO can be a lower-cost option, though its EPROM requires UV erasure rather than in-circuit flash reprogramming, which increases re-flash cycle time.
