PIC18F25K83-I/SP

Microcontrollers Overview

The PIC18F25K83-I/SP is an 8-bit microcontroller in the PIC18(L)F25/26K83 family, housed in a 28-pin SPDIP package. It features 32 KB of Flash program memory, 2048 bytes of Data SRAM, and 1024 bytes of Data EEPROM. The device operates at up to 64 MHz with a minimum instruction cycle of 62.5 ns. Operating voltage ranges from 2.3 V to 5.5 V, supporting industrial temperatures from -40°C to +85°C. It includes a 12-bit ADC2, CAN module, two UARTs, two I2Cs, SPI, DMA controllers, and 25 I/O pins.

Microcontrollers Feature Summary

• Integrates a 12-bit Analog-to-Digital Converter with Computation (ADC2) for automated signal analysis and threshold comparison.
• Includes a CAN module conforming to CAN 2.0B Active Specification with support for DeviceNet data byte filters and multiple acceptance masks.
• Features two Direct Memory Access (DMA) controllers for hardware-triggered data transfers between memory regions without CPU intervention.
• Supports advanced communication protocols including LIN, DMX, and DALI via its dual UART modules.

Microcontrollers Applications

• Automotive applications requiring CAN bus connectivity
• Industrial control systems utilizing LIN or DMX protocols
• Motor control designs leveraging CWG and PWM peripherals
• Sensor interfaces using ADC2 computation features

Microcontrollers Procurement Notes

Verify the specific suffix 'I/SP' confirms the Industrial temperature range (-40°C to +85°C) and SPDIP package type. Confirm the datasheet revision matches the required silicon version. Ensure ordering documentation references DS40001943C for accurate pinout and electrical specifications.

Microcontrollers Selection Notes

Select this component when 32 KB of Flash is sufficient and 28-pin SPDIP packaging is required. Compare against PIC18F26K83 if higher memory capacity is needed. Consider PIC18LF25K83 for lower voltage operation down to 1.8V. Verify peripheral requirements such as DMA and ADC2 compatibility.

Microcontrollers Part Context

This device belongs to the PIC18(L)F25/26K83 family of full-featured 8-bit microcontrollers designed for automotive and industrial use. The family shares core architecture but varies in memory size and package availability. The PIC18F25K83 specifically targets applications needing CAN technology and high-performance analog peripherals in a cost-effective 8-bit solution.

Microcontrollers Replacement Considerations

PIC18F26K83-I/SP offers identical features with 64 KB Flash and 4 KB RAM. PIC18LF25K83-I/SP provides the same functionality with extended low-voltage operation down to 1.8V. Cross-referencing pinouts and electrical characteristics is recommended before substitution.
