PIC24FV16KM204-I/PT - 16-bit XLP MCU, 32MHz, 16KB Flash | Microchip
The Microchip Technology PIC24FV16KM204-I/PT is a 16-bit PIC® eXtreme Low Power (XLP) microcontroller built on the PIC24F family architecture with 32 MHz operation, 16 KB Flash program memory (5.5K x 24 words), and 2 KB SRAM, housed in a 44-pin TQFP (10x10 mm) package. The device integrates 12-bit ADC, 8-bit DAC, on-chip operational amplifiers, comparators, configurable logic cells, and Capture/Compare/PWM peripherals, delivering a complete analog and digital signal-chain solution in a single IC. The wide 2.0 V to 5.5 V operating range supports both 3.3 V and 5 V designs, and the XLP idle/sleep modes extend battery life to microamp-level standby currents suitable for energy-harvesting endpoints.
A PIC microcontroller (MCU) is a compact single-chip computer based on Microchip's PIC® RISC architecture, integrating a CPU core, non-volatile program memory, RAM, and a fixed set of peripherals. PIC MCUs sit inside the broader microcontroller hierarchy as part of the embedded-computing family that bridges discrete logic and full microprocessors; the PIC24F sub-family is the 16-bit segment targeted at low-power, mixed-signal applications. The 32 MHz CPU delivers up to 16 MIPS, sufficient for sensor processing, motor control loops, and human-interface tasks while retaining deterministic interrupt response.
Key differentiating features include on-chip op-amps (configurable as amplifiers, buffers, or programmable-gain stages), an 8-bit DAC for bias or setpoint generation, a configurable logic cell (CLC) that implements combinational/sequential logic without external gates, and CTMU charge-time measurement for capacitive touch. Multiple serial interfaces (UART, SPI, I²C) and Capture/Compare/PWM modules support motor, LED, and timing applications. Hardware Real-Time Clock and Calendar (RTCC) with battery backup mode is integrated for time-keeping while the core is asleep.
The architecture combines a Harvard-style 16-bit datapath with peripheral pin-select (PPS), allowing flexible pin assignment to digital peripherals and simplifying PCB routing. The 44-TQFP package provides ample I/O for parallel displays, keypads, and sensor arrays while remaining hand-solderable. The XLP design uses nanoWatt XLP technology to achieve sub-microamp deep-sleep currents, which is critical for battery-powered IoT endpoints that must survive multi-year deployments on a single cell.
Typical applications include battery-powered sensor nodes, low-cost touch-interface front panels, portable medical monitoring accessories, consumer white-goods user-interface controllers, and LED lighting control. The integrated analog peripherals reduce BOM cost by eliminating external op-amps and comparators in many mixed-signal designs. The device is also well-suited to industrial HMI panels, electronic shelf labels, and remote controls where small pin count and integrated analog are advantageous.
When designing with the PIC24FV16KM204-I/PT, take advantage of the XLP sleep modes by leaving peripheral clocks gated when unused, and use the CLC module to implement glue logic in firmware-free hardware. Verify in-system programming (ICSP) pin access on the PCB for field firmware updates, and reserve adequate decoupling (100 nF + bulk) within 5 mm of the supply pins to keep ADC noise low. The integrated op-amps share pins with the ADC and DAC, so the pin-out diagram should be reviewed before signal-chain layout.
