PIC16F18856-E/SO

Microcontrollers Overview

The PIC16F18856-E/SO is an 8-bit microcontroller from the PIC16(L)F1885x family, housed in a 28-pin SOIC package. It features 28 KB of Flash program memory, 2 KB of data SRAM, and 256 bytes of EEPROM. The device operates at clock frequencies up to 32 MHz with a minimum instruction cycle of 125 ns. Operating voltage ranges from 2.3 V to 5.5 V, supporting industrial temperature applications from -40°C to +85°C.

Microcontrollers Feature Summary

• Integrates Analog-to-Digital Converter with Computation (ADC2) for automated signal analysis including averaging and filtering.
• Includes Core Independent Peripherals such as Hardware Limit Timer (HLT), Windowed Watchdog Timer (WWDT), and CRC/SCAN for application safety.
• Features eXtreme Low-Power (XLP) technology enabling low current consumption across various operating modes.

Microcontrollers Applications

• General-purpose embedded control systems
• Low-power battery-operated devices
• Industrial monitoring applications requiring safety timers

Microcontrollers Procurement Notes

Verify the specific ordering suffix '-E/SO' against official Microchip documentation to confirm the extended temperature range (-40°C to +85°C) and SOIC-28 package type. Ensure compatibility with existing PCB footprints and voltage levels before procurement.

Microcontrollers Selection Notes

Select this component when 28 KB of Flash memory and 25 I/O pins are required within a 28-pin package. Consider the ADC2 module for reducing firmware complexity in signal processing tasks. Verify that the 2.3V to 5.5V operating voltage range aligns with the system power supply design.

Microcontrollers Part Context

This part belongs to the PIC16(L)F18856/76 family of full-featured 8-bit microcontrollers. The 'PIC16F' designation indicates standard voltage operation compared to the 'PIC16LF' variant. The '-E' suffix denotes the industrial temperature grade, while '/SO' specifies the Small Outline Integrated Circuit package style.

Microcontrollers Replacement Considerations

Direct pin-compatible replacements within the same series include PIC16F18855 or PIC16F18857, provided memory sizes meet requirements. Cross-family migration requires verification of instruction set compatibility and peripheral mapping differences.
