- Ultra-low 1.8V minimum supply at 20 MHz enables operation from single-cell Li-ion or two-cell AA battery systems
- 16-pin QFN-16 package (4x4 mm) provides the smallest PIC16 USB-capable footprint for space-critical wearable designs
Applications
The PIC16F1454-I/ML is designed for USB HID, CDC, and custom class device applications such as PC interface dongles, USB-to-UART bridges, and keyboard/mouse accessories. Its 1.8V minimum operating voltage and compact QFN-16 form factor make it a natural fit for battery-powered USB accessories and wearable data-collection nodes. The 7KB Flash and 1KB RAM provide sufficient program and data space for full USB enumeration plus application logic.

Frequently Asked Questions
Does PIC16F1454-I/ML require an external crystal to run USB full-speed (12 Mbps), or does it have an internal USB clock?
PIC16F1454-I/ML has a built-in 48 MHz internal oscillator factory-calibrated for USB full-speed (12 Mbps) operation, so no external crystal or resonator is required. This removes 2 passive components and up to 3mm² of PCB area, which is significant in the 4x4mm QFN-16 form factor typical of USB dongle designs.
For a USB HID keyboard project, how much program memory does PIC16F1454-I/ML offer and is it sufficient for a full HID descriptor stack?
PIC16F1454-I/ML provides 7KB of Flash program memory and 1KB of SRAM. Microchip's USB library for HID class devices typically uses 4–5KB of Flash and 512 bytes of RAM, leaving 2KB of Flash and ~500 bytes of RAM free for custom key-mapping and LED logic. This is adequate for a standard 104-key USB HID keyboard implementation.
Can PIC16F1454-I/ML operate from a 3.3V LDO output in a USB bus-powered accessory design?
Yes. PIC16F1454-I/ML operates from 2.3V to 5.5V for USB mode and down to 1.8V for non-USB operation at up to 20 MHz. A 3.3V LDO regulator derived from the USB 5V bus provides a clean supply within this range. At 3.3V and 48 MHz the device's typical active current is approximately 4–6mA, which is well within the 100mA default USB bus-power budget.
When would PIC16F1454 be preferred over PIC18F14K50 for a cost-sensitive USB device?
PIC16F1454-I/ML offers a smaller 16-pin QFN-16 package versus PIC18F14K50's 20-pin SOIC, uses fewer GPIO lines, and is priced lower for simple USB CDC or HID applications. For applications needing only USB virtual COM or a basic HID interface with under 6KB of code, the PIC16F1454 saves approximately 20–30% in unit cost while meeting all USB 2.0 full-speed 12 Mbps requirements.
