PIC18F16Q20-I/SO

Microcontrollers Overview

The PIC18F16Q20-I/SO is an 8-bit microcontroller from the PIC18-Q20 series, featuring a RISC core with 64 kB of Flash program memory, 4 kB of SRAM data memory, and 256 B of EEPROM. It operates at a maximum clock frequency of 64 MHz within a voltage range of 1.8 V to 5.5 V. The device includes a 10-bit ADCC with 11 channels, an 8-bit DAC, DMA support, and a 16-bit PWM module. It provides 16 I/O pins in an SOIC-20 package and supports I2C, SPI, and USART interfaces.

Microcontrollers Feature Summary

• Supports multi-voltage I/O (MVIO) with independent pin domains for seamless cross-domain connectivity without external level shifters.
• Integrates an I3C target module enabling high-speed communication compatible with modern sensor interfaces.
• Features an 8-bit signal routing port that allows digital peripheral interconnection internally without consuming external pins.

Microcontrollers Applications

• Multi-sensor embedded systems requiring diverse voltage domain interfacing
• I3C to I2C communication bridges in space-constrained designs
• IoT system housekeeping and management functions

Microcontrollers Procurement Notes

Verify the specific suffix 'SO' confirms the SOIC-20 package type and '-I' indicates the industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status through official Microchip documentation or authorized distributor datasheets prior to finalizing procurement specifications.

Microcontrollers Selection Notes

Select this component when design requirements include MVIO flexibility for mixed-voltage sensors and I3C protocol support. The 64 kB Flash capacity suits applications needing moderate code storage, while the integrated signal routing reduces external component count compared to standard PIC18 families lacking virtual ports.

Microcontrollers Part Context

This part belongs to the PIC18-Q20 family, which emphasizes low-pin-count efficiency and advanced peripheral integration. It shares architectural similarities with other Q20 devices but offers specific memory sizes and I/O counts tailored for compact embedded control tasks in industrial and consumer electronics markets.

Microcontrollers Replacement Considerations

Direct substitutes within the same package and pinout include other PIC18F16Q20 variants with different temperature grades or packaging options, such as PIC18F16Q20-I/SS (SSOP-20). Cross-family replacements require careful verification of pin compatibility and peripheral feature parity.
