• Industrial communication interfaces using RS-232 or I2C
• Motor control systems leveraging complementary waveform generators

Microcontrollers Procurement Notes

Verify the suffix 'E' indicates industrial temperature range (-40°C to 85°C) and 'STX' denotes the specific 28-pin SSOP package variant. Confirm datasheet revision DS40002038C matches your design requirements. Ensure voltage supply aligns with the 2.3V to 5.5V specification for the non-LF variant.

Microcontrollers Selection Notes

Select this model when 14 KB program memory suffices for the application code. Choose over the PIC16F18456 if reduced memory footprint is acceptable. Consider the PIC16LF18455 variant if operation below 2.3V is required. Verify that the 28-pin SSOP package fits the PCB layout constraints.

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 PIC16F18456 but differs in memory size. The family emphasizes intelligent analog capabilities and core-independent peripherals for efficient system design.

Microcontrollers Replacement Considerations

PIC16F18456 offers identical peripheral sets with increased memory capacity. PIC16LF18455 provides the same functionality with extended low-voltage operation down to 1.8V. Cross-referencing pinouts and software compatibility is recommended before substitution.
