PIC18F87K90-I/PTRSL

Microcontrollers Overview

The PIC18F87K90-I/PTRSL is an 8-bit microcontroller from the PIC18F8xK90 family, featuring a PIC18 core and TQFP-80 package. It operates at up to 64 MHz with 128 kB Flash program memory, 4 kB SRAM, and 1 kB EEPROM. The device supports 1.8V to 5.5V supply voltage and includes a 12-bit ADC with 24 channels, 11 timers, three CCP/ECCP modules, two MSSP modules, and two EUSARTs. It integrates an LCD driver for up to 192 pixels and offers nanoWatt XLP low-power modes.

Microcontrollers Feature Summary

• Integrates nanoWatt XLP technology for ultra-low power consumption across Run, Idle, and Sleep modes.
• Includes an on-chip LCD driver capable of driving panels directly while in Sleep mode.
• Features a Charge Time Measurement Unit (CTMU) for capacitance and time measurement.
• Provides hardware Real-Time Clock and Calendar (RTCC) module with alarm functions.

Microcontrollers Applications

• Applications requiring direct LCD panel drive capability
• Systems utilizing mTouch sensing via CTMU
• Low-power embedded control designs

Microcontrollers Procurement Notes

Verify the specific suffix PTRSL indicates tape and reel packaging when sourcing. Confirm the -I designation corresponds to the industrial temperature range (-40°C to +85°C). Ensure compatibility with the 80-pin TQFP footprint during PCB layout. Cross-reference the datasheet DS39957D for electrical characteristics relevant to your operating voltage.

Microcontrollers Selection Notes

Select this component for high-performance 8-bit applications requiring extensive I/O and analog capabilities. The 128 kB Flash and 4 kB RAM support complex firmware. The inclusion of multiple CCP/ECCP modules and high-current sink/source pins makes it suitable for motor control or signal generation tasks requiring precise timing.

Microcontrollers Part Context

This part belongs to the PIC18F8xK90 family, which shares pinouts and peripheral sets with smaller memory variants like the PIC18F86K90. It is designed for migration from older PIC18 families such as the PIC18F87J90. The family emphasizes price performance while maintaining robust feature sets including LCD drivers and low-power technologies.

Microcontrollers Replacement Considerations

PIC18F87K90-E/PT is a verified alternative within the same family offering identical functionality but with an extended commercial temperature range (-40°C to +125°C).
