Frequently Asked Questions
Does PIC16F1455-I/ST include native USB support, and what USB speed does it support?
Yes. The PIC16F1455-I/ST integrates a USB 2.0 Full-Speed device controller supporting 12 Mbps data transfer, which is sufficient for HID, CDC, and custom USB class implementations. This on-chip USB eliminates the need for external USB bridge chips like CP2102 or FT232, reducing BOM cost and PCB space.
At what minimum supply voltage can PIC16F1455-I/ST operate, and what clock speed is available at that voltage?
The PIC16F1455-I/ST operates from as low as 1.8 V supply, running at up to 20 MHz at that voltage. At 3.3 V and above, the 4x PLL allows the core to reach 48 MHz. This flexibility makes it suitable for both coin-cell-powered sensor nodes and USB-powered host peripherals within the same device family.
For a compact USB keyboard or HID accessory PCB, how does the 14-pin TSSOP package affect layout complexity?
The TSSOP-14 package measures approximately 5 mm × 4.4 mm with 14 pins on a 0.65 mm pitch, delivering a very small footprint that accommodates a complete USB HID solution in under 50 mm² of board area including decoupling capacitors. This compactness suits wearables, USB dongles, and retrofitted legacy product USB upgrades.
What is the recommended procurement strategy for PIC16F1455-I/ST given its long factory lead time?
PIC16F1455-I/ST has a factory lead time of 13 weeks from Microchip Technology, which is longer than average. Design teams should plan for at least 14 to 16 weeks of total sourcing runway including distributor processing time, and consider placing buffer stock orders at product launch to prevent supply gaps during ramp-up.
