Applications
PIC16F1934-I/PT is well suited for mid-complexity embedded control designs such as HVAC controllers, industrial process monitors, and motor speed regulators that require multiple analog inputs alongside several communication interfaces. The 12-channel 10-bit ADC and dual MSSP peripherals allow simultaneous reading of temperature, pressure, and humidity sensors while communicating with a display or host controller over I2C. Consumer appliance controllers, programmable lighting systems, and POS terminal peripherals also benefit from the balance of Flash density, peripheral richness, and low operating voltage of this device.

Frequently Asked Questions
How many analog input channels and what ADC resolution does PIC16F1934-I/PT provide?
PIC16F1934-I/PT integrates a 12-channel, 10-bit successive-approximation ADC capable of resolving signals with approximately 4.88 mV per step at 5 V supply. All 12 channels can be multiplexed into the single ADC core, and conversion time is typically 12 µs at 32 MHz, allowing over 80 ksps throughput for multi-channel sensor polling.
At what minimum voltage can PIC16F1934-I/PT operate, and how does supply voltage affect maximum clock speed?
PIC16F1934-I/PT operates from 1.8 V minimum, but at 1.8 V the maximum clock frequency is limited to 16 MHz. At 2.3 V and above, full 32 MHz operation is available, yielding 8 MIPS throughput. This makes the device suitable for single-cell lithium batteries in slow-clock mode and dual-cell alkaline packs for full-speed operation.
Which serial communication interfaces are on-chip and what are their maximum speeds on PIC16F1934-I/PT?
PIC16F1934-I/PT includes a hardware MSSP module configurable as I2C master/slave up to 1 MHz (Fast-mode Plus) or SPI up to 8 Mbps, plus an enhanced USART supporting asynchronous baud rates up to 2 Mbps at 32 MHz system clock. These three interface modes allow simultaneous connection to sensors, memory devices, and host processors without bit-banging overhead.
How does PIC16F1934-I/PT compare to PIC16F1933 for applications needing more I/O pins?
PIC16F1934-I/PT in the 44-pin TQFP provides 36 digital I/O pins, while the pin-compatible PIC16F1933 in a 28-pin SPDIP offers only 24 I/O pins. Both share the same 4096-word Flash and 10-bit ADC architecture, so firmware is portable between the two. Designers choosing PIC16F1934 gain 12 additional I/O pins at the cost of a larger package footprint.
For a motor speed controller, how many PWM outputs does PIC16F1934-I/PT support and at what resolution?
PIC16F1934-I/PT features up to 2 independent Enhanced CCP (ECCP) modules each capable of 10-bit PWM with a period up to 65 ms at 32 MHz clock. The enhanced modules also support half-bridge and full-bridge output modes, providing 4 PWM pins for direct control of an H-bridge motor driver at frequencies up to 125 kHz without external logic.
