• Data acquisition devices requiring analog-to-digital conversion
• Motor control applications utilizing CCP/PWM modules
• Industrial communication interfaces using SPI or I2C

Microcontrollers Procurement Notes

Verify that the suffix 'I' corresponds to the industrial temperature range (-40°C to +85°C) and 'SO' indicates the SOIC-28 package. Confirm the 'T' suffix denotes tape and reel packaging if required for automated assembly. Ensure the specific revision matches the design requirements as datasheet updates may occur.

Microcontrollers Selection Notes

Select this component when a dedicated USB interface is necessary alongside standard peripheral connectivity. The 24 KB flash size suits moderate firmware complexity. Consider the 4.2 V minimum voltage limit; for lower voltage operation, the PIC18LF2458 variant is appropriate. Verify pin compatibility if migrating from older PIC18F2455/2550 designs.

Microcontrollers Part Context

This part belongs to the PIC18F2458/2553/4458/4553 family, which shares core architectural features but differs in memory size and pin count. The 28-pin variants like the PIC18F2458 are optimized for compact designs compared to the 40/44-pin counterparts. It serves as a bridge between basic 8-bit MCUs and higher-end USB-capable devices.

Microcontrollers Replacement Considerations

PIC18F2550T-I/SO offers similar functionality with different memory configurations. PIC18LF2458T-I/SO provides extended low-voltage operation down to 2.0V. Cross-reference pinouts and memory sizes carefully when substituting.
