Key Features
- 28 KB Flash and 2 KB RAM with 32 MHz maximum clock frequency for capable 8-bit embedded control
- Operates from 1.8 V minimum supply at 16 MHz enabling ultra-low-power battery-operated IoT and wearable designs
- Integrated ADC2 and DAC channels in a 48-pin TQFP package for mixed-signal sensing and actuation without external converters
Applications
The PIC16LF19186T-I/PT is suited for low-power embedded control applications such as sensor nodes, home automation, and IoT edge devices where a 1.8 V supply rail allows direct operation from a single lithium coin cell or two AA batteries. Its 28 KB Flash provides enough program memory for complex control algorithms with an RTOS, while the integrated ADC and DAC support direct sensor conditioning and analog output generation. The TQFP-48 package and 32 MHz clock make it a capable choice for industrial monitoring, motor control, and consumer appliance applications.

Frequently Asked Questions
At what supply voltage and clock frequency can PIC16LF19186T-I/PT operate for low-power battery designs?
The PIC16LF19186T-I/PT can operate at a minimum supply voltage of 1.8 V while running at up to 16 MHz, making it directly usable from a single lithium coin cell or two-cell AA battery stack. At full 32 MHz clock speed, a higher supply voltage is required, but the 1.8 V at 16 MHz mode provides an excellent balance of processing speed and power consumption for sensor and IoT node applications.
How does the 28 KB Flash memory of PIC16LF19186T-I/PT compare to typical 8-bit microcontrollers for control firmware size?
With 28 KB of Flash program memory and 2 KB of RAM, PIC16LF19186T-I/PT sits in the mid-range of 8-bit PIC16 family devices, offering about 4× more code space than a basic 7 KB PIC16 variant. This allows developers to include multi-sensor fusion algorithms, bootloader routines, and communication stacks such as I2C or SPI drivers within the same chip, reducing the need for external memory in most embedded control applications.
Which mixed-signal peripheral integration makes PIC16LF19186T-I/PT suitable for sensor conditioning without external ICs?
PIC16LF19186T-I/PT integrates an ADC2 (second-generation ADC with computation features) and DAC channels on-chip, enabling direct digitization of analog sensor signals and generation of analog reference or control outputs within a single 48-pin TQFP device. This integration removes the need for discrete ADC and DAC ICs in designs with fewer than 10 analog channels, reducing BOM cost and PCB area in compact sensor nodes and industrial instruments.
