Frequently Asked Questions
How much program memory does the PIC16F1938-I/ML provide for firmware development?
The PIC16F1938-I/ML offers 16,384 words (28 KB) of flash program memory, sufficient for moderately complex 8-bit firmware including communication stacks, sensor drivers, and control algorithms. This compares favorably to the PIC16F887 with only 14,336 words, giving developers room for additional application logic.
At what maximum clock speed can the PIC16F1938-I/ML execute instructions?
The PIC16F1938-I/ML operates at up to 32 MHz, executing most instructions in a single 4-clock cycle, yielding up to 8 MIPS throughput. This speed is adequate for real-time control loops, UART communication at 115,200 bps, and PWM generation for motor or LED dimming applications.
Does the PIC16F1938-I/ML include analog peripherals, and how does this simplify circuit design?
Yes. The PIC16F1938-I/ML integrates both an ADC and a DAC on-chip, eliminating the need for discrete analog conversion ICs in many designs. This reduces BOM cost and PCB space while providing analog input sampling and voltage output capability directly from the 2.5 V to 5.5 V supply rail.
What is the package style of the PIC16F1938-I/ML and how does it compare to DIP alternatives?
The PIC16F1938-I/ML is packaged in a 28-pin VQFN (QFN) measuring approximately 4 mm × 4 mm, which is roughly 80% smaller than an equivalent 28-pin DIP package. The QFN exposed pad also improves thermal dissipation, making it the preferred choice for compact surface-mount PCB designs in consumer and industrial products.
