Applications
The PIC18F6490-I/PT is well suited for utility meters, white goods control panels, and point-of-sale displays that require a direct-drive LCD interface alongside analog sensing. Its 16 KB Flash and integrated LCD driver eliminate an external LCD controller IC, reducing BOM cost and board area in space-constrained designs. The device also targets industrial HMI panels and home appliance controllers that benefit from its multi-protocol serial peripherals and 10-bit ADC.

Frequently Asked Questions
How does the on-chip LCD driver in PIC18F6490-I/PT help reduce component count in a utility meter design?
The integrated LCD direct-drive controller eliminates the need for a standalone display driver IC, reducing the BOM by one component and freeing up at least 4 PCB connection pins otherwise needed for a driver chip. The controller supports multiplexed segment LCDs with up to 1/4 duty cycle directly from the 3.3 V or 5 V supply rail.
What serial communication interfaces are available for connecting external sensors or host processors?
The PIC18F6490-I/PT includes an enhanced USART (EUSART) supporting asynchronous RS-232 at standard baud rates up to 115200 baud, plus synchronous SPI and I2C peripherals for interfacing temperature sensors, EEPROMs, and real-time clock modules in a single-board design.
What is the maximum clock frequency and ADC resolution, and are these sufficient for a residential energy meter?
The device runs at up to 20 MHz (10 MIPS) and features a 10-bit ADC. For residential single-phase energy metering at 50 Hz or 60 Hz line frequency, sampling voltage and current at 20 MHz provides adequate oversampling, and the 10-bit ADC resolution supports Class 1 accuracy with software gain and offset calibration.
How many GPIO pins are available in the TQFP-64 package, and what is the body size for PCB layout planning?
The TQFP-64 package has a 10 mm x 10 mm body with 64 pins on 0.5 mm pitch, exposing more than 44 general-purpose I/O lines. This gives designers flexibility to interface keypad matrices, serial peripherals, relay drivers, and LCD segments without an external expander for typical appliance control applications.
