Microchip PIC24F16KA102T-I/ML: A Low-Power 16-bit Microcontroller for Embedded Systems

The relentless drive towards smarter, more efficient, and connected devices places increasing demands on the microcontrollers at their core. For designers of battery-powered or energy-conscious embedded systems, selecting the right MCU is a critical decision that balances processing capability with power consumption. The Microchip PIC24F16KA102T-I/ML stands out as a premier solution, engineered specifically to excel in this challenging environment.

This member of Microchip's expansive PIC24F family is a 16-bit microcontroller built on a modified Harvard architecture, offering a robust blend of performance and efficiency. Its core operates at up to 16 MIPS (16 MHz), providing ample computational power for a wide range of applications, from complex sensor data processing to managing user interfaces and communication protocols.

The defining characteristic of the PIC24F16KA102T is its exceptionally low power consumption. This is achieved through a suite of advanced power-management features. Key among these are multiple software-selectable sleep modes:

Sleep: The core CPU is halted while peripherals can remain active.

Idle: The CPU is halted but the system clock continues to run.

Doze: The CPU and peripheral clocks run at a ratio, reducing CPU power.

Deep Sleep: Achieves the lowest possible current draw (typically in the nanoampere range) by shutting down most internal circuitry, relying on a low-power timer or external event for wake-up.

This capability makes it ideal for applications that spend significant time in a standby state, waking up briefly to perform a task before returning to a deep sleep, thereby maximizing battery life.

Beyond its power credentials, this MCU is packed with integrated peripherals that reduce system component count and total cost. It features 16 KB of Flash memory and 512 Bytes of RAM, alongside a rich set of peripherals including:

Multiple communication interfaces (UART, SPI, I2C™)

Timers and Capture/Compare/PWM (CCP) modules

A 10-bit Analog-to-Digital Converter (ADC)

Hardware Real-Time Clock and Calendar (RTCC)

Housed in a compact 28-pin QFN (ML) package, the PIC24F16KA102T-I/ML is perfectly suited for space-constrained designs. Its extended temperature range (-40°C to +85°C) ensures reliable operation in industrial and automotive environments.

ICGOODFIND: The Microchip PIC24F16KA102T-I/ML is a highly integrated and power-optimized 16-bit microcontroller. It is an outstanding choice for developers creating energy-sensitive embedded systems, such as portable medical devices, remote sensors, smart meters, and other battery-powered applications where longevity and reliability are paramount.
