Applications
The PIC17C44-16/L targets legacy industrial motor controllers, programmable logic replacements, and embedded real-time control systems requiring fast computation at 16 MHz. Its hardware multiplier and extended instruction set are well matched to control algorithms such as PID loops and lookup-table interpolation that exceed the performance of standard PIC16 devices. Maintenance and repair of existing PIC17C-based equipment, as well as cost-sensitive high-volume industrial products already qualified on this device, represent its primary procurement use case.

Frequently Asked Questions
What clock speed and hardware multiply capability does the PIC17C44-16/L offer compared to standard PIC16 devices?
The PIC17C44-16/L runs at 16 MHz, executing most instructions in 4 clock cycles for 4 MIPS throughput, and includes a hardware 8×8-bit multiplier that completes a multiply in a single instruction cycle. Standard PIC16 devices lack a hardware multiplier, requiring software multiply routines that consume 10–20 instruction cycles, so the PIC17C44-16/L is significantly faster for math-intensive control loops.
How much program memory does the PIC17C44-16/L contain, and what does OTP mean for production use?
The PIC17C44-16/L contains 8 KB of One-Time Programmable (OTP) program memory addressed via a 16-bit bus. OTP means the device is programmed once at manufacturing and cannot be erased or re-programmed, so it is cost-effective for high-volume production runs where firmware is fully validated before programming but unsuitable for field-updateable designs.
What I/O count and package does the PIC17C44-16/L provide for a complex control board?
The device provides 33 I/O pins in a 44-pin PLCC package, along with three timer/counter modules, two capture/compare units, and one PWM channel. The PLCC-44 footprint requires a socket or surface-mount pad area of approximately 17.8 mm × 17.8 mm, which is larger than modern LQFP alternatives but suitable for through-hole socket mounting on legacy or serviceable hardware.
What is the operating supply voltage range for the PIC17C44-16/L at full 16 MHz speed?
The PIC17C44-16/L operates from a 4.5 V to 5.5 V supply rail and requires 5 V to run reliably at the full 16 MHz clock frequency. This makes it compatible with 5 V industrial logic systems but not directly usable in 3.3 V designs without a voltage regulator, distinguishing it from modern low-voltage PIC devices that run from 1.8 V to 5.5 V.
