Key Features
- Full-speed USB 2.0 device controller with 3.3 V operation at 48 MHz enables direct USB connectivity without an external USB bridge chip
- 128 KB flash and 4 KB RAM running at 12 MIPS supports complex firmware including USB class drivers and RTOS kernels
- 12-bit ADC with DMA transfer reduces CPU load during continuous sampling, freeing cycles for USB communication and control tasks
Applications
The PIC18F27J53T-I/SO is ideal for USB data acquisition dongles, HID interface adapters, and industrial field calibrators that require direct USB connectivity alongside substantial analog measurement capability. Its 12-bit ADC with DMA enables continuous signal sampling at hundreds of kilo-samples per second while the USB controller streams data to a PC host without CPU intervention. The SOIC-28 package and 3.3 V operation make it compatible with USB bus-powered designs that draw current directly from the 500 mA VBUS rail.

Frequently Asked Questions
What USB speed and voltage does PIC18F27J53T-I/SO support, and does it need an external 3.3 V regulator?
The PIC18F27J53T-I/SO implements a full-speed USB 2.0 device interface operating at 12 Mbps from a 3.3 V supply. When powered from a 5 V USB VBUS, an external 3.3 V LDO regulator is required, but the device can also operate directly from a regulated 3.3 V rail in bus-powered USB accessories, keeping the BOM cost low.
How does the 12-bit ADC with DMA in PIC18F27J53T-I/SO benefit a USB data logger application?
The 12-bit ADC with 4,096 resolution steps captures analog signals with greater precision than the 10-bit ADC on standard PIC18 devices. The DMA controller transfers ADC results directly to RAM at rates up to several hundred kSPS, freeing the 12 MIPS CPU to format USB packets and manage the USB stack simultaneously, allowing uninterrupted high-throughput streaming to a PC host.
How much program storage does PIC18F27J53T-I/SO offer, and is it sufficient for a USB CDC virtual COM port driver plus application code?
The PIC18F27J53T-I/SO provides 128 KB of flash program memory and 4 KB of SRAM. Microchip's USB stack with a CDC class driver typically occupies 8 KB to 12 KB of flash, leaving over 110 KB for application firmware including sensor drivers, data formatting, and a lightweight task scheduler, which is adequate for most single-function USB instruments.
