Frequently Asked Questions
What USB specification does the PIC18F27J53 support and does it need an external USB transceiver?
The PIC18F27J53 supports USB 2.0 full-speed operation at 12 Mbps with a fully integrated on-chip transceiver, requiring no external USB PHY chip. This integration simplifies PCB design, reduces component count, and lowers bill-of-materials cost for USB HID, CDC, and mass-storage device designs.
How does the PIC18F27J53's DMA controller benefit high-throughput data logging designs?
The integrated DMA controller transfers data between peripherals and RAM at up to 48 MHz bus speed without halting the CPU, freeing processor cycles for real-time tasks. This is especially useful in USB data-logging applications where ADC samples at 100 ksps must be streamed to flash or USB bulk transfers simultaneously.
What is the minimum supply voltage for the PIC18F27J53 and how low can its sleep current go?
The PIC18F27J53 operates from a 2.0 V to 3.6 V supply, and its XLP deep-sleep mode reduces current consumption to as low as 20 nA, extending battery life significantly in portable USB accessories. The wide supply range also simplifies interfacing with standard 3.3 V USB bus-powered designs.
Which package does the PIC18F27J53-I/ML use and what PCB footprint does it require?
The I/ML suffix specifies the 28-pin QFN (VQFN-28) package with an approximately 6 mm × 6 mm footprint and 0.65 mm pin pitch. This thermally efficient, leadless package is 60% smaller than an equivalent 28-pin SOIC, making it a good choice for compact USB dongle or wearable sensor node PCBs.
