Frequently Asked Questions
Does the PIC16LF1454-I/JQ support USB 2.0 natively, and what is its maximum clock speed?
Yes, the PIC16LF1454-I/JQ integrates a full-speed USB 2.0 device interface directly on-chip, operating at up to 20 MHz. This removes the need for an external USB bridge, reducing BOM cost and PCB area in USB peripheral designs.
How much program memory and RAM does the PIC16LF1454-I/JQ provide for USB firmware development?
The PIC16LF1454-I/JQ offers 7 KB of Flash program memory and 512 bytes of RAM, which is sufficient for USB HID or CDC class firmware on a resource-efficient 8-bit platform running from a 1.8 V minimum supply.
What package is used for the PIC16LF1454-I/JQ and how does it help with compact PCB designs?
The PIC16LF1454-I/JQ is packaged in a UQFN-16 with 16 pins in an ultra-small QFN footprint, enabling dense PCB layouts for wearables, USB dongles, and miniaturized embedded accessories where board space is at a premium.
Is the PIC16LF1454-I/JQ a suitable drop-in when migrating from PIC16F1454 in a low-voltage design?
The PIC16LF1454-I/JQ is the low-voltage variant of the PIC16F1454 series, extending the minimum supply down to 1.8 V compared to 2.3 V for the standard variant, while retaining the same 7 KB Flash, 512-byte RAM, USB 2.0, and 20 MHz maximum frequency. It is a direct migration target for designs requiring lower operating voltage.
