Key Features
- Integrated LCD segment driver eliminates the need for an external LCD controller, enabling direct multiplexed display drive from a single 8-bit PIC16 TQFP-44 device
- 32 MHz maximum clock with 1.8 V minimum supply allows operation from a single lithium coin cell in battery-powered instrumentation
- 4 KB Flash and 256-byte RAM with integrated ADC support complete standalone sensor-display applications without external memory or converter ICs
Applications
PIC16LF1934-I/PT targets portable metering instruments, energy monitors, and consumer appliances where a segmented LCD panel must be driven directly from the microcontroller without a dedicated display driver IC. Its 1.8 V minimum supply with 32 MHz operation enables coin-cell powered thermometers, humidity sensors, and utility meters that display readings on low-power LCD glass. Industrial panel meters and smart-home controllers also use this device to combine ADC-based signal acquisition and LCD output in a single TQFP-44 component.

Frequently Asked Questions
How does the integrated LCD driver of PIC16LF1934-I/PT reduce BOM cost compared with external controller solutions?
By integrating the LCD segment driver on-chip, PIC16LF1934-I/PT removes the need for a separate LCD controller IC that would otherwise add 1 to 2 components and 5 to 10 additional PCB connections. The integrated driver supports multiplexed segment drives, allowing direct connection to common glass displays with up to 32 segments within the 44-pin TQFP footprint.
At what minimum supply voltage can PIC16LF1934-I/PT operate, and what clock speed is achievable at that voltage?
PIC16LF1934-I/PT operates from a minimum supply of 1.8 V, at which it can run at up to 16 MHz delivering 4 MIPS throughput. Increasing the supply to 2.7 V or above unlocks the full 32 MHz maximum clock speed, making the device flexible for both coin-cell battery designs at 1.8 V and 5 V mains-derived regulated supply applications.
Which sensor interface applications suit PIC16LF1934-I/PT given its ADC and Flash memory capacity?
PIC16LF1934-I/PT suits temperature, humidity, and current-sense applications where the ADC samples an analog signal and the result is displayed directly on an LCD segment panel. The 4 KB Flash accommodates a measurement algorithm, calibration table, and LCD segment map for a 3.5-digit display, while the 256-byte RAM buffers up to 128 16-bit samples between display refresh cycles at 32 MHz.
How does PIC16LF1934-I/PT compare to a PIC16 device without an LCD driver when designing a handheld meter?
A PIC16 device without an integrated LCD driver requires an external HT1621 or PCF8576 LCD controller, adding at least 1 IC, 3 SPI wires, and 8 to 16 segment line connections to the PCB. PIC16LF1934-I/PT eliminates this overhead, keeping the 44-pin TQFP as the sole active component for a 3.5-digit LCD meter, which saves approximately 15 mm2 of board area and reduces the assembly component count in high-volume handheld production.
