PIC16LF18344-I/SS

Microcontrollers Overview

The PIC16LF18344-I/SS is an 8-bit microcontroller from the PIC16(L)F183xx family, utilizing a C Compiler Optimized RISC architecture with only 49 instructions. It features 7 KB of Program Flash Memory (PFM), 512 bytes of Data SRAM, and 256 bytes of EEPROM Data Flash Memory. The device operates at clock frequencies up to 32 MHz with a minimum instruction cycle of 125 ns. It includes a 10-bit Analog-to-Digital Converter with up to 17 external channels, two comparators, and a 5-bit Digital-to-Analog Converter. The unit supports eXtreme Low Power (XLP) technology for efficient operation in low-power applications.

Microcontrollers Feature Summary

• Integrates Peripheral Pin Select (PPS) functionality to enable flexible pin mapping for digital peripherals such as CLC, CWG, CCP, PWM, and communication modules.
• Features eXtreme Low Power (XLP) technology with sleep mode current as low as 40 nA at 1.8V and doze/idle modes to minimize power consumption.
• Includes configurable logic cells (CLC) and a Numerically Controlled Oscillator (NCO) for precise linear frequency generation and custom waveform creation.
• Supports multiple timer configurations including up to four 8-bit timers and three 16-bit timers, alongside comprehensive interrupt capabilities.

Microcontrollers Applications

• General purpose embedded control systems requiring low power consumption
• Battery-operated devices utilizing XLP sleep and idle modes

• Precision signal generation using NCO and DSM modules

Microcontrollers Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature range. Confirm that the 'LF' designation aligns with the intended operating voltage range of 1.8V to 3.6V. Ensure compatibility with existing design tools and programming interfaces before finalizing procurement decisions.

Microcontrollers Selection Notes

Select this component when designing for low-voltage environments between 1.8V and 3.6V. Consider the 7 KB program memory and 512 bytes RAM for moderate code complexity. Evaluate the need for PPS flexibility if pin assignments require reconfiguration during development. Compare against higher-memory variants if larger data storage or extended temperature ranges are necessary.

Microcontrollers Part Context

This microcontroller belongs to the PIC16(L)F183xx series, which combines analog, core-independent, and communication peripherals. The series emphasizes low-pin-count designs with high feature density. The 'I' suffix indicates an industrial temperature range rating, suitable for broader environmental conditions compared to commercial grade options.

Microcontrollers Replacement Considerations

Check for pin-compatible alternatives within the same family, such as the PIC16LF18345 or PIC16LF18346, which offer increased memory sizes. Verify that any substitute maintains the required 1.8V-3.6V operating voltage and SSOP-20 package dimensions.
