Microchip PIC24FV32KA302-I/SS: A Comprehensive Technical Overview

The Microchip PIC24FV32KA302-I/SS represents a robust and versatile 16-bit microcontroller within Microchip's extensive portfolio, engineered for applications demanding high performance, ultra-low power consumption, and robust peripheral integration. This device is a member of the enhanced PIC24F "KA" family, which is specifically designed to operate in power-sensitive and harsh environmental conditions, making it a prime candidate for battery-powered, industrial, and automotive applications.

Core Architecture and Performance

At its heart lies a modified Harvard architecture 16-bit CPU core capable of operating at up to 8 MIPS (16 MHz). This core efficiently executes a rich instruction set, balancing processing power with energy efficiency. A significant advantage of this architecture is its 24-bit wide instruction word, which allows for more powerful single-cycle instructions and a linear addressing space of up to 4 million words, simplifying programming and data management.

Memory Configuration

The device is equipped with a substantial and flexible memory subsystem. It features 32 KB of self-programmable Flash memory for application code storage. This Flash is rated for high endurance (typically 10,000 erase/write cycles) and features built-in Error Correction Code (ECC) for enhanced data reliability. Complementing this is 2 KB of SRAM, which provides ample space for data variables and stack operations during real-time processing.

Ultra-Low Power Management

A defining characteristic of the PIC24FV32KA302 is its advanced XLP (eXtreme Low Power) technology. This technology enables unprecedented power savings across multiple operational modes. Key specifications include:

Deep Sleep currents as low as 20 nA: Ideal for long-term battery standby.

Real-Time Clock (RTC) operation at 500 nA: Allows time-keeping while the core CPU is completely shut down.

Active run currents below 200 µA/MHz: Ensures efficient operation during computation tasks.

This suite of features makes it exceptionally suitable for devices that must operate for years on a single battery.

Integrated Peripherals and System Integration

The microcontroller boasts a rich set of integrated peripherals that reduce external component count and total system cost.

Analog: It includes a 10-bit 500 ksps Analog-to-Digital Converter (ADC) with up to 12 channels, crucial for sensor interfacing. It also features two analog comparators for quick signal response.

Control & Communication: For connectivity, it is equipped with multiple serial communication modules, including UART, SPI, and I²C (up to 400 kHz), facilitating easy communication with other ICs and peripherals.

Timing & Control: It contains five 16-bit timers/counters, offering flexible timing, pulse generation, and input capture capabilities. A dedicated hardware Real-Time Clock and Calendar (RTCC) is also included for time-sensitive applications.

Robustness: The inclusion of a Hardware Capacitive Voltage Divider (CVD) for touch sensing and a CRC/SCAN module for system health monitoring further enhances its robustness for safety-critical applications.

Packaging and Application Hints

Housed in a 20-pin SSOP (Shrink Small Outline Package), the PIC24FV32KA302-I/SS offers a compact footprint for space-constrained PCB designs. Its wide operating voltage range (2.0V to 5.5V) and extended temperature range (-40°C to +125°C) ensure reliable operation in industrial and automotive environments where power supply fluctuations and extreme temperatures are common.
