PIC24F16KA101-I/SS

Microcontrollers Overview

The PIC24F16KA101-I/SS is a 20-pin, 16-bit Flash microcontroller from the PIC24F16KA102 family. It features a modified Harvard architecture with up to 16 MIPS operation at 32 MHz. The device includes 16 Kbytes of Flash program memory, 1.5 Kbytes of SRAM, and 512 bytes of Data EEPROM. Key peripherals include a 10-bit ADC with 9 channels, two UARTs, SPI, I²C, three 16-bit timers, and a Charge Time Measurement Unit (CTMU). Operating voltage ranges from 1.8V to 3.6V.

Microcontrollers Feature Summary

• Integrates nanoWatt XLP technology for extreme low-power consumption across multiple operating modes.
• Includes a Charge Time Measurement Unit (CTMU) for high-resolution capacitance sensing and time measurement.
• Features a hardware Real-Time Clock and Calendar (RTCC) capable of running in Deep Sleep mode.
• Supports flexible clock switching and Doze mode to optimize power usage during peripheral activity.

Microcontrollers Applications

• Capacitive touch sensing interfaces
• Low-power embedded control systems
• Precision timing and pulse generation applications

Microcontrollers Procurement Notes

Verify the specific suffix 'I/SS' corresponds to the Industrial temperature range (-40°C to +85°C) and SSOP-20 package as defined in the official datasheet. Confirm that the '-ES' engineering sample designation is not required for production units. Ensure compatibility with standard ICSP programming tools for this pin count.

Microcontrollers Selection Notes

Select this component when migrating from 8-bit platforms requiring higher computational performance without DSP complexity. The consistent pinout within the family allows for easy scaling to larger memory variants. Verify that the 20-pin form factor meets board space constraints while providing sufficient I/O for the target application.

Microcontrollers Part Context

This part belongs to the PIC24F16KA102 family, which shares identical peripheral sets across 20-pin and 28-pin packages. The primary distinction between family members is the Flash program memory size (8K vs 16K). This specific model offers 16Kbytes of Flash, positioning it for applications needing more code space than the 8K variant.

Microcontrollers Replacement Considerations

PIC24F08KA101-I/SS: Offers identical peripherals and pinout but with reduced 8Kbytes of Flash memory.

Microcontrollers FAQ

Can the RTCC module operate during Deep Sleep mode?

Yes, the hardware Real-Time Clock and Calendar (RTCC) module can continue to run in Deep Sleep mode, allowing for timekeeping while the core and most peripherals are powered down.

What is the resolution of the CTMU module?

The Charge Time Measurement Unit (CTMU) provides time measurement and delay/pulse generation capabilities with a resolution down to 1 nanosecond.
