Applications
The PIC18LF44J11-I/PT suits power-constrained embedded control designs such as wireless sensor nodes, smart meters, and portable medical devices where the 2 V minimum supply enables operation from two AA batteries through most of their discharge curve. Its 48 MHz core speed and DMA channel support demanding peripheral tasks like UART data logging and ADC-triggered transfers without burdening the CPU. The combination of 16 KB Flash and 4 KB RAM provides sufficient resources for complex state machines, communication stacks, and sensor fusion algorithms in a single-chip solution.

Frequently Asked Questions
What is the maximum clock speed and RAM capacity of the PIC18LF44J11-I/PT?
The PIC18LF44J11-I/PT runs at up to 48 MHz, delivering 12 MIPS of instruction throughput, and provides 4 KB of on-chip SRAM alongside 16 KB of Flash. This combination handles real-time control loops, buffered UART communication, and multi-channel ADC data collection simultaneously without requiring external memory expansion.
How low can the PIC18LF44J11-I/PT's supply voltage go in low-power nanoWatt mode?
The PIC18LF44J11-I/PT operates with a minimum supply voltage of 2 V at up to 8 MHz in nanoWatt mode, allowing the device to run from two nearly-depleted AA alkaline batteries or a single LiPo cell well into its discharge curve. This low-voltage capability extends battery life significantly in wireless sensor nodes, remote data loggers, and portable medical monitors compared to devices with a 3 V minimum.
What advantage does the DMA controller provide for high-speed peripheral data handling?
The DMA controller in the PIC18LF44J11-I/PT moves data between memory and peripherals such as ADC, UART, and SPI autonomously at 48 MHz bus speeds, without interrupting the CPU core. This allows the processor to continue executing control algorithms while background transfers stream sensor samples into SRAM buffers, increasing effective system throughput in data-acquisition and communications applications.
Which package does the PIC18LF44J11-I/PT use and how does it support in-system testing?
The PIC18LF44J11-I/PT is housed in a quad flat package (QFP) with a standard SMT footprint compatible with automated pick-and-place assembly. It also supports boundary scan (JTAG), which allows board-level interconnect testing at production and in-system firmware programming through standard 4-wire JTAG headers, reducing manufacturing debug time for complex multi-chip PCBs.
