Key Features

  • 14 KB Flash program memory and 1 KB RAM provide ample storage for mid-complexity embedded control firmware in a single 8-bit MCU
  • 10-bit ADC with multiple channels enables direct analog sensor measurement without external ADC ICs in sensing and control applications
  • 32 MHz maximum clock frequency with low-voltage LF-grade operation minimizes current consumption in battery-powered and energy-harvesting designs

Applications

PIC16LF1566T-I/SO is well suited for low-power embedded control applications including home automation sensors, motor control interfaces, and portable measurement instruments. The 10-bit ADC and 32 MHz PIC16 core make it effective for reading resistive sensors, thermistors, and potentiometers while running control algorithms in real time. Its SOIC package and low operating voltage simplify integration into compact, battery-operated consumer and industrial devices.

Frequently Asked Questions

How much Flash and RAM does PIC16LF1566T-I/SO provide, and is that sufficient for a simple sensor data-logging application?

PIC16LF1566T-I/SO provides 14 KB of Flash program memory and 1 KB of data RAM. For a simple sensor data-logging application sampling an analog sensor at 10 Hz and storing readings over a USB or UART link, 14 KB of Flash accommodates the main loop, interrupt routines, and communication drivers, while 1 KB RAM handles buffering for typical 8-bit and 10-bit data packets.

What ADC resolution and maximum clock frequency does PIC16LF1566T-I/SO support for analog sensing tasks?

PIC16LF1566T-I/SO integrates a 10-bit ADC and supports a maximum clock frequency of 32 MHz. The 10-bit ADC delivers 1024 quantization levels, sufficient to resolve millivolt-level changes from resistive bridges or NTC thermistors, while 32 MHz operation keeps sensor sampling and data processing latency under 1 µs per instruction cycle.

Which package does PIC16LF1566T-I/SO come in and how does the LF designation affect supply voltage requirements?

PIC16LF1566T-I/SO is packaged in a standard SOIC (small outline) format. The LF designation indicates a low-voltage variant that operates at reduced VDD levels, typically 1.8 V to 3.6 V, extending battery life compared to the standard PIC16F variants that require 2.3 V to 5.5 V, making it suitable for 2-cell AA or single-cell Li-ion powered products.
