PIC16F18446-E/GZ

Microcontrollers Overview

The PIC16F18446-E/GZ is an 8-bit microcontroller from the PIC16(L)F184XX family, featuring a RISC core with up to 28 Kbytes of Program Flash Memory and 2 KB of Data SRAM. It includes 256 bytes of Data EEPROM and supports operating frequencies up to 32 MHz. The device provides 18 I/O pins, a 12-bit ADC with computation (ADC2), a 5-bit DAC, two comparators, and multiple digital peripherals including CCP, PWM, CWG, NCO, CLC, and DSM. Communication interfaces include one EUSART and two MSSP modules.

Microcontrollers Feature Summary

• Features eXtreme Low-Power technology with multiple power-saving modes including Sleep, Idle, and Doze to minimize active power consumption.
• Includes a 12-bit Analog-to-Digital Converter with computation capabilities for automated post-processing and threshold comparison functions.
• Supports Peripheral Pin Select functionality to remap digital peripheral inputs and outputs to various I/O pins.

Microcontrollers Applications

• General purpose embedded control systems
• Low-power battery-operated devices
• Industrial automation controllers
• Consumer electronics requiring analog signal processing

Microcontrollers Procurement Notes

Verify the specific package type corresponding to the '/GZ' suffix against official Microchip documentation, as datasheet tables list PDIP, SOIC, SSOP, TSSOP, and UQFN options without explicitly defining the '/GZ' designation. Confirm voltage range compatibility, noting that the 'F' variant operates between 2.3V and 5.5V. Ensure environmental ratings match the '-E' industrial/extended temperature specification requirements for your application.

Microcontrollers Selection Notes

Select this model when 18 I/O pins and 17 ADC channels are required, distinguishing it from the 12-channel PIC16F18426. Choose the 'F' variant over 'LF' if operation below 2.3V is not needed or if higher speed performance at standard voltages is preferred. Consider the '/GZ' package availability for surface-mount assembly needs, ensuring pin count matches the 20-pin form factor.

Microcontrollers Part Context

This component belongs to the PIC16(L)F184XX series of full-featured, low pin count microcontrollers. The family shares identical core features, oscillator structures, and peripheral sets, differing primarily in memory size, I/O count, and ADC channel quantity. The PIC16F18446 represents the high-end configuration within the 14/20-pin subset of this family.

Microcontrollers Replacement Considerations

PIC16LF18446-E/GZ offers equivalent functionality with extended low-voltage operation ranges. PIC16F18426-E/GZ serves as a pin-compatible alternative with reduced I/O and ADC channels. Cross-referencing with the PIC16(L)F18456/56 series may be necessary for applications requiring additional I/O ports beyond the 18 available on this device.
