Applications
The PIC18F67K90-I/MRRSL is well suited for smart energy meters, gas meter displays, and utility sub-meters that require both precise analog measurement and direct LCD segment driving without an external display controller. Industrial sensor nodes and portable medical monitors benefit from its 12-bit ADC and nanoWatt XLP sleep modes that keep average current below 1 µA in duty-cycled operation. The integrated EEPROM and large Flash also support over-the-air calibration updates and event logging in building automation or HVAC control applications.

Frequently Asked Questions
How many LCD segments can the PIC18F67K90-I/MRRSL drive directly, and what supply voltage does the LCD module require?
The integrated LCD driver supports up to 132 segments at operating voltages of 2V to 5.5V, eliminating the need for an external LCD controller IC. This reduces BOM cost and PCB space for smart meters, thermostats, and portable instruments that display alphanumeric or custom segment characters.
What ADC resolution does the PIC18F67K90-I/MRRSL provide and how many channels are accessible simultaneously?
The device integrates a 12-bit ADC with up to 24 multiplexed input channels, delivering 4096-count resolution suitable for temperature, pressure, and flow measurement in utility meters. The 12-bit depth provides 0.8 mV resolution at a 3.3V reference, enabling accurate process monitoring without external signal conditioning.
How does the PIC18F67K90-I/MRRSL's nanoWatt XLP technology compare to standard PIC18 devices for coin-cell operation?
The nanoWatt XLP sleep current of the PIC18F67K90-I/MRRSL is below 20 nA, roughly 10 times lower than conventional PIC18 variants. A 225 mAh coin cell can sustain the device in sleep for over 1 year at 1-second wake intervals, enabling tamper-detection or gas-meter data logging without a line supply.
What serial communication interfaces are available on the PIC18F67K90-I/MRRSL for connecting to external sensors or network modules?
The PIC18F67K90-I/MRRSL provides USART, SPI, and I2C interfaces, covering 3 major protocols with hardware support up to 64 MHz clock rates. USART supports full-duplex asynchronous communication at up to 4 Mbps, while I2C operates in standard (100 kHz), fast (400 kHz), and fast-plus (1 MHz) modes for connecting RTC modules, EEPROMs, and sensor ICs.
