PIC16F18456-I/SO

Microcontrollers Overview

The PIC16F18456-I/SO is a 28-pin microcontroller featuring 28 KB of Program Flash Memory, 2 KB of Data SRAM, and 256 bytes of Data EEPROM. It operates at speeds up to 32 MHz with an operating voltage range of 2.3V to 5.5V for industrial temperature ranges (-40°C to 85°C). Key peripherals include a 12-bit ADC2 with computation, two EUSARTs, two MSSPs, four Configurable Logic Cells (CLCs), three Complementary Waveform Generators (CWGs), five CCP modules, and one Numerically Controlled Oscillator (NCO).

Microcontrollers Feature Summary

• Integrates Intelligent Analog peripherals including a 12-bit ADC with automated post-processing and computation features.
• Supports low-power operation through eXtreme Low-Power (XLP) technology, allowing CPU and peripheral cycle rate differentiation.
• Offers flexible I/O mapping via Peripheral Pin Select (PPS) for digital peripheral input/output remapping.
• Includes Core Independent Peripherals such as Configurable Logic Cells and Complementary Waveform Generators to offload the CPU.

Microcontrollers Applications

• General purpose embedded control systems requiring low pin count solutions.
• Battery-powered applications utilizing extreme low-power sleep modes.
• Industrial communication interfaces using RS-232, RS-485, or LIN compatible EUSARTs.
• Motor control or signal generation applications leveraging CWG and NCO modules.

Microcontrollers Procurement Notes

Verify the suffix 'I' indicates Industrial temperature range and 'SO' denotes SOIC package. Confirm the device is from Microchip Technology Inc. Ensure datasheet DS40002038C is referenced for electrical specifications. Check for RoHS compliance status if required by your manufacturing standards. Validate that the specific batch matches the current revision of the component documentation.

Microcontrollers Selection Notes

Select this model when 28 KB of program memory is required, distinguishing it from the 14 KB PIC16F18455 variant. Choose the 'F' prefix over 'LF' if operation above 3.6V or up to 5.5V is necessary. Consider the SOIC package only if surface mount compatibility with standard 7.5 mm footprint is needed. Evaluate if the 26 available I/O pins meet the interface requirements for the target application design.

Microcontrollers Part Context

This component belongs to the PIC16(L)F184XX family of full-featured, low pin count microcontrollers. It shares architectural similarities with the PIC16F18455 but offers double the program memory capacity. The family emphasizes intelligent analog capabilities and core-independent peripherals to reduce system power consumption and CPU load in general-purpose applications.

Microcontrollers Replacement Considerations

The PIC16F18455 is a functional substitute within the same package if reduced memory (14 KB vs 28 KB) is acceptable. The PIC16LF18456 offers identical functionality but with a lower voltage operating range (1.8V to 3.6V). Verify software compatibility and pinout alignment before substituting any member of the PIC16(L)F184XX family.
