The 44-pin QFN package provides a small 8 mm x 8 mm footprint with an exposed pad that enhances thermal dissipation and gives access to the full pin count. CMOS-compatible I/O buffers support 5 V-tolerant inputs on most pins, allowing interface to legacy 5 V peripherals without level translation. The 16-bit modified Harvard architecture separates program and data buses for single-cycle fetches while sharing the same address space. Typical applications include IoT sensor nodes, battery-powered metering, industrial control, motor control, embedded automation, and low-power board designs. The XLP peripherals enable continuous operation for years on a single coin cell. When designing with this part, place the exposed pad (EP) thermal pad with multiple thermal vias for proper heat dissipation. Verify all unused inputs are tied to VDD or VSS per Microchip recommendations to minimize current draw in Deep Sleep. The RTCC, DSWDT, and DSBOR wake sources allow the CPU core to remain asleep while timekeeping and watchdog tasks continue, which is the key XLP design pattern for ultra-low-power designs.

PIC24F16KA304-I/PT

PIC24F16KA304-I/PT - 16-bit 32MHz XLP MCU 16KB Flash | Microchip

The Microchip Technology PIC24F16KA304-I/PT is a 16-bit RISC microcontroller from the PIC24F XLP family, featuring 16KB of Flash program memory, 2KB of RAM, and 512 bytes of EEPROM, housed in a 44-pin TQFP (10x10 mm) package. It operates at up to 32 MHz delivering 16 MIPS, integrates a 12-bit ADC, and is engineered around Microchip's eXtreme Low Power (XLP) technology. A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory (Flash/ROM), data memory (RAM), and integrated peripherals such as timers, ADC/DAC, communication interfaces, and I/O ports. The PIC24F16KA304 belongs to the 16-bit PIC24F family, which sits in Microchip's hierarchy: 16-bit MCU -> PIC24F -> PIC24F XLP low-power series -> power-constrained and battery-powered applications. Compared with 8-bit PIC16/PIC18 parts, the 16-bit core enables larger address spaces, wider data paths, and richer DSP-style arithmetic for signal processing. Key features include a 12-bit A/D converter with up to 30 channels depending on package, multiple communication peripherals (UART, SPI, I2C), 5 timers, a Real-Time Clock and Calendar (RTCC) that operates in Deep Sleep, plus dedicated Deep Sleep Brown-Out Reset (DSBOR) and Deep Sleep Watchdog Timer (DSWDT). XLP technology enables typical Deep Sleep currents measured in nanoamperes, making the device well suited to battery-powered designs. The CTMU (Charge Time Measurement Unit) supports capacitive touch sensing and precise time-of-flight measurements. The architecture uses a modified Harvard design with separate program and data buses, a 24-bit instruction word for compact code density, and a deterministic interrupt model. Up to 32 MHz operation across an industrial -40C to +85C range provides ample headroom for closed-loop control, sensor fusion, and USB-less communication stacks. Typical applications include battery-powered sensor nodes, IoT edge devices, portable medical instrumentation, consumer wearables, and industrial data loggers. The wide operating range also suits automotive accessory and ruggedized telemetry systems. When designing with this part, pair a low-Iq LDO with the MCU, route the 32.768 kHz crystal traces short and guarded, and use the CTMU only after calibrating against an internal reference to achieve reliable touch sensing.
