PIC24FV16KM102T-I/SO - 16-Bit 32MHz MCU, 16KB Flash | Microchip
The Microchip Technology PIC24FV16KM102T-I/SO is a 16-bit microcontroller from the PIC PIC XLP 24F family, featuring 16KB of Flash program memory (5.5K x 24 words), 1KB of SRAM, and 512 bytes of EEPROM in a 28-pin SOIC (0.295 inch / 7.50 mm width) package. It operates from a wide 2.0V to 5.5V supply, supports a maximum CPU clock of 32 MHz, and integrates a 12-bit ADC, multiple Capture/Compare/PWM (MCCP/SCCP) modules, Configurable Logic Cells (CLC), and analog comparators.
A PIC microcontroller (MCU) is a compact, self-contained computer-on-a-chip built around a Harvard-architecture CPU, on-chip Flash memory for program storage, SRAM for runtime data, and a rich set of peripherals (ADC, timers, communications, comparators). The PIC24F family uses a 16-bit modified Harvard core that delivers substantially more computational throughput than 8-bit PIC10/12/16 parts while retaining the deterministic interrupt model that makes PIC MCUs popular in real-time control. The PIC24FV sub-family specifically extends the supply down to 2.0V, enabling 2-cell battery operation, while the XLP (eXtreme Low Power) nanoWatt technology targets sleep currents in the microamp range.
Key features include 25 MIPS throughput at 32 MHz, an integrated 12-bit ADC with up to 500 ksps conversion rate, up to 21 channels of 10-bit ADC depending on package, three operational amplifiers (10 MHz GBW) for signal conditioning, multiple PWM channels with complementary outputs and dead-band control, and four Configurable Logic Cells for glue-logic replacement. Hardware peripherals include I2C, SPI, and UART interfaces, plus a real-time clock and calendar (RTCC) module with calendar mode. The 28-pin SOIC footprint enables hand-soldering and breadboarding, which is uncommon for modern high-pin-count MCUs.
Architecturally, the PIC24FV16KM102T uses a 16-bit modified Harvard CPU with a 24-bit instruction word for orthogonal addressing, 17 x 17-bit hardware multiplier, and a 32-bit barrel shifter. The bus matrix allows concurrent Flash fetch and SRAM access for predictable interrupt latency, and the integrated charge pump generates the core 1.8V from the external supply, allowing single-supply designs as low as 2.0V.
Typical applications include ultra-low-power battery sensor nodes (e.g., IoT and wireless sensor remotes), portable medical monitoring devices, low-cost motor control for small DC fans and pumps, LED lighting drivers, and consumer white goods requiring human-interface control. The wide operating voltage and rich analog peripherals make the part well suited to 5V-tolerant designs that mix analog sensing and digital control.
When designing with this device, engineers should budget for Flash endurance of 1000 erase/write cycles minimum and a typical 20-year data retention. Use the ICD 3 or MPLAB REAL ICE for programming and debugging; the device supports both legacy ICSP and 4-wire JTAG programming. The 28-SOIC package has a thermal resistance theta_JA near 80 C/W, so no special thermal management is required for typical 8-30 mA active currents.
