Frequently Asked Questions
What is the minimum operating voltage of PIC18F67J90-I/PT and at what clock speed can it run at that voltage?
The PIC18F67J90-I/PT can operate at a minimum supply voltage of 2V while running at up to 8 MHz. This low-voltage operation is well-suited for battery-powered designs using 2 x AA alkaline cells or a single-cell lithium coin battery, where the supply voltage may drop below 2.5V during normal discharge while still requiring active MCU and LCD operation.
How does the integrated LCD driver in PIC18F67J90-I/PT differ from using an external LCD controller in terms of design complexity?
The integrated LCD driver in PIC18F67J90-I/PT allows direct driving of segment LCD glass panels through dedicated LCD segment and common pins on the 64-pin TQFP, eliminating the need for a separate LCD controller IC, its supply decoupling, and a serial or parallel bus interface. This integration reduces BOM by 1 to 2 components, removes inter-IC communication latency, and simplifies firmware since the LCD is controlled via on-chip memory-mapped registers rather than an external protocol.
What memory resources does PIC18F67J90-I/PT provide and how do they support complex embedded applications?
The PIC18F67J90-I/PT includes 128 kB of Flash program memory and 4 kB of on-chip RAM. The 128 kB Flash provides space for complex application code, communication protocol stacks, and calibration lookup tables, while the 4 kB RAM supports real-time data buffering, display frame buffers, and RTOS task stacks. This combination is sufficient for applications like smart utility meters with multi-tariff firmware or portable instruments with local data logging.
For a smart utility meter design, how does PIC18F67J90-I/PT compare to PIC18F67K90-I/PTRSL in clock speed and RAM?
PIC18F67J90-I/PT offers a maximum clock of 48 MHz and 4 kB RAM, while the PIC18F67K90-I/PTRSL runs at up to 64 MHz with 1 kB EEPROM but differs in RAM configuration. The J90 variant's higher 4 kB RAM suits applications requiring larger data buffers such as display frame data and communication packet queues, whereas the K90 variant's 64 MHz clock and nanoWatt XLP sleep current below 1 µA may be preferred where faster processing and deeper power saving matter more than RAM size.
