• Features a 12-bit ADC controller capable of automating capacitive voltage divider techniques for touch sensing
• Includes an integrated LCD controller with a charge pump for low-voltage operation and backlighting drive
• Supports active clock tuning of the HFINTOSC for high accuracy across voltage and temperature variations

Microcontrollers Applications

• Battery-powered LCD applications
• General purpose embedded control systems
• Touch sensing interfaces using capacitive voltage divider techniques

Microcontrollers Procurement Notes

Verify that the ordering suffix 'T' corresponds to tape-and-reel packaging as indicated by standard Microchip naming conventions. Confirm the '-I' suffix denotes the industrial temperature range (-40°C to +85°C). Ensure the 'SS' suffix matches the required 28-pin SSOP physical package dimensions for your PCB layout.

Microcontrollers Selection Notes

Select this component when 28KB of program memory and 2KB of RAM are required alongside advanced analog peripherals. It is suitable for designs needing precise timing via active clock tuning or specific LCD segment counts up to 96. Consider the 2.3V minimum operating voltage for power supply design constraints.

Microcontrollers Part Context

This part belongs to the PIC16(L)F191xx series, which offers eXtreme Low-Power (XLP) technology. The family supports various pin counts including 28, 40, 44, and 48 pins. The PIC16F19156 variant specifically provides higher memory capacity compared to the PIC16F19155 within the same package options.

Microcontrollers Replacement Considerations

PIC16F19155T-I/SS offers identical peripheral sets but with reduced memory (14KB Flash, 1KB RAM). PIC16LF19156T-I/SS provides the same specifications but operates at a lower voltage range (1.8V to 3.6V).
