What are the key features of PIC16F18346T-I/SS?
- 32 MHz 8-bit PIC16 core with 28 KB Flash and 256 B EEPROM for embedded control and data logging
- 10-bit ADC and 5-bit DAC on-chip enable analog signal acquisition and generation without external components
- Dual SPI/I2C interfaces operating down to 2.3 V in a compact 20-pin SSOP package for multi-peripheral low-power designs
What is PIC16F18346T-I/SS used for?
The PIC16F18346T-I/SS suits embedded control applications in home appliances and industrial sensors where its 32 MHz performance and dual communication interfaces reduce external component count. Battery-powered field instruments benefit from the 2.3 V minimum operating voltage and integrated 10-bit ADC for direct sensor digitization without an external ADC chip. Motor control and LED driver boards use the on-chip 5-bit DAC and hardware PWM peripherals to generate analog reference voltages and drive signals from a single 20-pin device.

Frequently Asked Questions
How does the PIC16F18346T-I/SS achieve 2.3 V minimum operation, and at what clock frequency is that guaranteed?
The PIC16F18346T-I/SS is specified to operate correctly at 2.3 V minimum input voltage when clocked at up to 16 MHz. Above 16 MHz and up to the maximum 32 MHz, a higher supply voltage is required. This low-voltage capability makes the device directly compatible with single-cell Li-ion batteries during end-of-discharge, extending useful operating time in portable embedded systems.
What ADC and DAC resolutions does PIC16F18346T-I/SS offer, and how many channels are available?
The PIC16F18346T-I/SS integrates a 10-bit ADC with up to 12 input channels and a 5-bit DAC providing 32 output voltage levels. The 10-bit ADC resolution corresponds to approximately 3.2 mV per step at 3.3 V, sufficient for temperature, pressure, and light sensor digitization. The on-chip DAC eliminates the need for an external analog reference or signal generator in cost-sensitive designs.
For a multi-sensor I2C bus design, how many I2C peripherals can PIC16F18346T-I/SS communicate with simultaneously?
The PIC16F18346T-I/SS provides 2 independent I2C/SPI interfaces, allowing the MCU to manage two separate I2C buses or one SPI and one I2C bus simultaneously. A typical configuration connects an I2C temperature sensor and an I2C OLED display on separate buses to avoid address conflicts, all controlled from the 32 MHz 8-bit core running application firmware stored in 28 KB Flash.
