PIC16LF18855-I/ML

Microcontrollers Overview

The PIC16LF18855-I/ML is an 8-bit microcontroller from the PIC16(L)F1885x family, utilizing a C Compiler Optimized RISC architecture with only 49 instructions. It features up to 14 KB of Flash program memory, 1 KB of data SRAM, and 256 bytes of EEPROM. The device operates at clock frequencies up to 32 MHz with a minimum instruction cycle of 125 ns. It supports an operating voltage range of 1.8V to 3.6V and functions within industrial temperature ranges of -40°C to 85°C or extended ranges up to 125°C.

Microcontrollers Feature Summary

• Integrates eXtreme Low-Power (XLP) technology for ultra-low current consumption in Sleep mode and peripheral operation.
• Includes Analog-to-Digital Converter with Computation (ADC2) that automates signal analysis tasks such as averaging and filtering without CPU intervention.
• Features Core Independent Peripherals (CIP) like Configurable Logic Cells (CLC), Numerically Controlled Oscillator (NCO), and Data Signal Modulator (DSM) to offload processing from the CPU.
• Supports functional safety requirements through hardware modules including Hardware Limit Timer (HLT) and Windowed Watchdog Timer (WWDT).

Microcontrollers Applications

• General purpose embedded control systems requiring low power consumption
• Battery-powered portable devices and sensor nodes
• Industrial applications needing hardware-based safety mechanisms
• Signal acquisition systems utilizing automated ADC post-processing

Microcontrollers Procurement Notes

Verify the specific package variant required, as the I/ML suffix denotes a QFN package while other suffixes indicate SOIC or SSOP. Confirm the operating voltage range matches your system design, as the LF series is restricted to 1.8V-3.6V unlike the standard F series. Ensure all VDD and VSS pins are connected at the board level to prevent functionality issues. Check for AEC-Q100 qualification if automotive compliance is necessary.

Microcontrollers Selection Notes

Select this component when a balance of moderate memory size and advanced analog peripherals is needed. The LF variant is appropriate for strict voltage constraints below 2.3V. Consider the ADC2 capabilities if reducing firmware complexity for signal processing is a priority. Evaluate the Core Independent Peripherals to determine if they can replace external discrete logic components.

Microcontrollers Part Context

This device belongs to the PIC16(L)F1885x family of full-featured 8-bit microcontrollers. It shares architectural similarities with the PIC16F18855 but differs in operating voltage specifications. The family emphasizes integration of analog and digital peripherals to minimize external component count. It serves as a successor to older mid-range PIC devices with enhanced power management and safety features.

Microcontrollers Replacement Considerations

PIC16F18855-I/ML offers identical pinout and peripheral sets but supports a wider voltage range of 2.3V to 5.5V. PIC16LF18854-I/ML provides reduced memory capacity (7 KB Flash, 512 B RAM) with the same package and peripherals.
