Key Features

  • 8-bit PIC16 CPU core running up to 32 MHz with low-power idle modes
  • 10-bit ADC for precise analog sensor signal acquisition
  • 5-bit DAC for analog output generation without external components
  • Dual SPI and I2C interfaces for flexible multi-peripheral connectivity
  • 256 bytes of on-chip EEPROM for non-volatile parameter storage
  • Operates at minimum 2.3 V supply at 16 MHz for battery-powered designs
  • SOIC-20 package with 18 I/O pins for versatile peripheral interfacing

Applications

The PIC16F18346-E/SO is well suited for compact sensor interface designs including temperature monitors, current sensors, and proximity detectors that benefit from on-chip 10-bit ADC and 5-bit DAC capabilities. Its dual SPI/I2C interfaces enable direct connection to multiple sensors, EEPROM, and display modules from a single SOIC-20 device running at up to 32 MHz. The 2.3 V minimum supply voltage also makes it a practical choice for coin-cell or single-cell lithium battery-powered IoT edge nodes requiring non-volatile EEPROM data retention.

Frequently Asked Questions

What analog peripherals are integrated in the PIC16F18346-E/SO that eliminate external components?

The PIC16F18346-E/SO integrates a 10-bit ADC with multiple input channels, a 5-bit DAC for analog output, and a comparator module, removing the need for external analog ICs and reducing BOM count in sensor interface designs operating at up to 32 MHz.

How does the EEPROM on the PIC16F18346-E/SO benefit field-configurable IoT applications?

The 256 bytes of on-chip EEPROM in the PIC16F18346-E/SO allows firmware to persistently store calibration coefficients, device addresses, and operating parameters through power cycles, eliminating the need for an external serial EEPROM in low-cost IoT node designs.

Which communication-heavy sensor hub designs can the PIC16F18346-E/SO handle with its dual serial interfaces?

With 2 SPI and 2 I2C interfaces, the PIC16F18346-E/SO in its 20-pin SOIC package can simultaneously manage an SPI-based environmental sensor, an I2C display, and an I2C EEPROM at up to 32 MHz, covering multi-peripheral industrial IoT hub configurations without requiring a larger or more expensive MCU.
