PIC16LC71-04I/SO

Microcontrollers Overview

The PIC16LC71-04I/SO is an 8-bit CMOS microcontroller from the PIC16C71X family, featuring a high-performance RISC CPU with a fully static design. It utilizes low-power, high-speed CMOS EPROM technology for program memory. The device operates within a wide voltage range of 2.5V to 6.0V and supports clock frequencies up to 20 MHz. It includes 1K x 14 words of EPROM program memory and 36 bytes of data RAM. Key peripherals include a Timer0 module and a 4-channel 8-bit analog-to-digital converter.

Microcontrollers Feature Summary

• Features a high-performance RISC architecture with a Harvard structure, enabling single-cycle instruction execution for most operations.
• Integrates a 4-channel 8-bit analog-to-digital converter suitable for low-cost analog interface applications.
• Includes special features such as Power-on Reset (POR), Watchdog Timer (WDT), and Brown-out Reset (BOR) circuitry.
• Supports In-Circuit Serial Programming (ICSP) via RB6 and RB7 pins for flexible code updates.

Microcontrollers Applications

• Thermostat control systems
• Pressure sensing interfaces
• Appliance control units
• Security and remote sensor devices

Microcontrollers Procurement Notes

Verify the specific suffix 'SO' corresponds to the SOIC-18 plastic package and 'I' indicates the industrial temperature range (-40°C to +85°C). Confirm that the '04' designation aligns with the required maximum operating frequency specifications for your application environment. Ensure compatibility with existing development tools supporting the PIC16C71X family.

Microcontrollers Selection Notes

Select this component when a cost-effective 8-bit solution with integrated A/D conversion is required. It is suitable for designs needing EPROM flexibility for code customization without UV erasure requirements. Consider the 13 I/O pins and 36 bytes of RAM against application complexity. Verify power supply constraints fit the 2.5V to 6.0V operational range.

Microcontrollers Part Context

This part belongs to the PIC16C71X family of 8-bit microcontrollers, which are enhanced versions of the PIC16C5X architecture. The family shares common core features like the eight-level deep hardware stack and interrupt capabilities. The PIC16C71 variant specifically offers 1K of program memory, distinguishing it from the 512-word PIC16C710 and the higher-memory PIC16C715.
