PIC18C801T-I/L

Microcontrollers Overview

The PIC18C801T-I/L is an 8-bit microcontroller from the PIC18C601/801 family, featuring a high-performance RISC CPU with up to 2 Mbytes of linear external program memory addressing and 1536 bytes of on-chip RAM. It supports operating frequencies from DC to 25 MHz and includes a 10-bit Analog-to-Digital Converter with 12 input channels. The device provides extensive I/O capabilities through Ports A-H and J, along with four timers, two CCP modules, and serial communication interfaces including MSSP and Addressable USART.

Microcontrollers Feature Summary

• Supports up to 2 Mbytes of external program memory addressing with flexible 8-bit or 16-bit external memory interface modes.
• Includes a 10-bit Analog-to-Digital Converter module with fast sampling rates and conversion capability during SLEEP mode.
• Features programmable Low Voltage Detection (LVD) and multiple reset sources including Power-on Reset and Watchdog Timer.
• Integrates Master Synchronous Serial Port (MSSP) supporting SPI and I2C protocols alongside an Addressable USART.

Microcontrollers Applications

• Applications requiring large external program memory expansion via the 80-pin TQFP package.
• Systems utilizing the 16-bit external memory interface for complex data processing tasks.
• Industrial control environments benefiting from the wide operating voltage range and industrial temperature specifications.

Microcontrollers Procurement Notes

Verify the specific ordering suffix 'I/L' against the manufacturer's current product identification system to confirm package type and temperature grade. Ensure compatibility with existing design constraints regarding the 84-pin PLCC footprint and moisture sensitivity levels before finalizing procurement decisions.

Microcontrollers Selection Notes

Select this component when designs require significant external address space up to 2 Mbytes combined with robust analog input handling via twelve ADC channels. Consider the availability of dedicated chip select signals and the 8x8 hardware multiplier for performance-intensive arithmetic operations within the 8-bit architecture.

Microcontrollers Part Context

This device belongs to the PIC18C601/801 series of high-performance ROM-less microcontrollers designed for applications needing extensive external memory interfacing. It shares architectural similarities with other PIC18 devices but distinguishes itself through its specific pinout configuration and support for both 8-bit and 16-bit external bus widths.
