Microchip PIC16LF87T-I/SS: Low-Power 8-Bit Flash Microcontroller Overview

The Microchip PIC16LF87T-I/SS stands as a prominent member of the versatile PIC® 16F87x family, engineered specifically for applications where power efficiency, performance, and integration are paramount. This 8-bit microcontroller (MCU), built on Microchip's enhanced mid-range core, combines a rich set of peripherals with the company's renowned low-power technology, making it an ideal solution for battery-operated and portable devices.

At the heart of this MCU is a high-performance RISC CPU with 35 single-word instructions. Its 8-bit architecture is optimized for deterministic operation and efficient handling of control-oriented tasks. A key feature is its nanowatt-technology power management, which allows the device to operate over an extensive voltage range (2.0V to 5.5V) and offers multiple selectable clock modes. This enables designers to finely balance processing speed with power consumption, drastically extending battery life in end products.

The 'LF' designation confirms its low-voltage operation capability. The device boasts 7 KB of self-programmable Flash program memory and 368 bytes of RAM, providing ample space for complex firmware. A standout feature is the 256 bytes of EEPROM data memory, allowing for the reliable storage of critical data—such as calibration constants or user settings—even when power is removed.

Its peripheral set is comprehensive and designed for embedded control. It includes:

Analog-to-Digital Converter (ADC): A 10-bit ADC with up to 11 channels for precise sensor interfacing and data acquisition.

Timers: Multiple timers/counters, including Timer1 with oscillator support for real-time clock (RTC) applications.

Communication Interfaces: Both MSSP (SPI/I2C) and USART modules facilitate seamless communication with a vast ecosystem of peripherals like sensors, memory chips, and other controllers.

Capture/Compare/PWM (CCP) Modules: Two CCP modules provide critical functions for controlling power peripherals like motors and for generating timing signals.

In-Circuit Debug (ICD): Integrated debugging support accelerates development and troubleshooting.

Housed in a 28-pin Shrink Small Outline (SSOP) package, the PIC16LF87T-I/SS offers a compact footprint suitable for space-constrained PCB designs. Its industrial temperature range (-40°C to +85°C) ensures reliable operation in harsh environmental conditions.

ICGOOODFIND: The PIC16LF87T-I/SS is a highly integrated, feature-rich 8-bit microcontroller that excels in low-power scenarios. Its robust peripheral set, combined with nanowatt-class power management and non-volatile memory options, makes it a superior choice for designers developing connected, portable, and power-sensitive applications such as sensor nodes, medical devices, advanced remote controls, and industrial automation systems.
