PIC24F08KA101-E/SS

Microcontrollers Overview

The PIC24F08KA101-E/SS is a 20-pin, 16-bit Flash microcontroller from the PIC24F16KA102 family. It features an 8 Kbyte program memory and 1.5 Kbyte SRAM. The device operates at frequencies up to 32 MHz with a modified Harvard architecture. Key peripherals include two UARTs, one SPI, one I²C module, three 16-bit timers, a 10-bit ADC with nine channels, dual analog comparators, and a Charge Time Measurement Unit (CTMU). It supports extreme low-power modes down to 20 nA in Deep Sleep.

Microcontrollers Feature Summary

• Integrates nanoWatt XLP technology for significant power reduction across multiple operating modes.
• Includes a Charge Time Measurement Unit (CTMU) enabling high-resolution capacitive sensing and time measurement.
• Features a hardware Real-Time Clock and Calendar (RTCC) capable of running during Deep Sleep mode.
• Provides flexible clocking options including internal oscillators and a Phase Locked Loop (PLL).

Microcontrollers Applications

• Capacitive touch sensing interfaces
• Low-power embedded control systems
• Battery-operated sensor nodes

Microcontrollers Procurement Notes

Verify that the specific ordering suffix '-E/SS' corresponds to the commercial temperature range and SSOP package variant required for your design. Confirm pinout compatibility with existing layouts, as this 20-pin device shares the family block diagram but differs in memory size from the 16K variants. Ensure voltage levels match the 1.8V to 3.6V operating specification.

Microcontrollers Selection Notes

Select this component when migrating from 8-bit platforms to 16-bit performance without requiring DSP capabilities. It is suitable for applications needing moderate flash memory (8KB) and extensive peripheral integration. Consider the 28-pin variants if additional I/O pins or alternative I2C/SPI pin mappings are necessary for the system design.

Microcontrollers Part Context

This device belongs to the PIC24F16KA102 family, which unifies 20-pin and 28-pin packages with consistent peripheral sets. While the datasheet title references the 16KA102 series, Table 1-1 explicitly lists the PIC24F08KA101 as a member with identical peripheral functionality except for reduced program memory. This allows for scalable migration within the same pinout scheme.

Microcontrollers Replacement Considerations

PIC24F16KA101-E/SS offers identical pinouts and peripherals with increased 16KB program memory. PIC24F08KA102 provides the same 8KB memory but in a 28-pin package.
