PIC16F685T-I/SS

Microcontrollers Overview

The PIC16F685T-I/SS is a 20-pin SSOP microcontroller from the PIC16 family. It features 4096 words of Flash program memory, 256 bytes of SRAM, and 256 bytes of Data EEPROM. The device supports a maximum clock frequency of 20 MHz and operates within a voltage range of 2.0V to 5.5V. It includes an Enhanced Capture/Compare/PWM module, two analog comparators, a 10-bit ADC with 12 channels, and an Enhanced USART.

Microcontrollers Feature Summary

• Features a high-performance RISC CPU with only 35 instructions and single-cycle execution for most operations.
• Includes a precision internal oscillator factory calibrated to ±1% with software-selectable frequency ranging from 8 MHz to 32 kHz.
• Provides enhanced power management capabilities including Sleep mode, Power-on Reset, Brown-out Reset, and Ultra Low-Power Wake-up.
• Integrates an Enhanced Capture/Compare/PWM module supporting up to four output channels with programmable dead time.

Microcontrollers Applications

• Industrial control systems requiring robust reset features and interrupt capabilities
• Battery-powered devices utilizing low-power sleep modes and wide operating voltage ranges
• Motor control applications leveraging the ECCP+ module with PWM output steering
• Communication interfaces using the Enhanced USART with auto-baud detect

Microcontrollers Procurement Notes

Verify that the ordering suffix 'I' corresponds to the industrial temperature range (-40°C to +85°C) and 'SS' indicates the SSOP-20 package. Confirm RoHS compliance status through official Microchip documentation. Ensure the datasheet version matches the silicon revision required for your design implementation.

Microcontrollers Selection Notes

Select this component when specific requirements include an Enhanced Capture/Compare/PWM module and an Enhanced USART. It is suitable for designs needing a precision internal oscillator without external crystal components. Consider alternatives like the PIC16F687 or PIC16F689 if I2C/SPI or additional UART functionality is necessary instead of ECCP+.

Microcontrollers Part Context

This part belongs to the PIC16F631/677/685/687/689/690 family of 20-pin flash-based microcontrollers. It shares the same pinout and core architecture as other members but differs in peripheral configuration, specifically offering ECCP+ and EUSART while lacking SSP/I2C found in siblings like the PIC16F687.

Microcontrollers Replacement Considerations

Direct functional substitutes within the same package include PIC16F687T-I/SS and PIC16F689T-I/SS, provided the application can accommodate the presence of SSP/I2C modules. Verify pin compatibility and peripheral availability before substitution.
