Applications
PIC18LF8527-I/PT is suited for energy-metering equipment, industrial data loggers, and multi-sensor building automation controllers that require a large I/O count alongside low sleep-mode power consumption. Its 48 KB Flash and 80-pin TQFP package accommodate complex firmware stacks controlling LCD panels, multiple serial buses, and analog front ends simultaneously. The 2 V minimum supply operation enables deployment in long-life battery systems such as smart utility meters and remote telemetry units requiring years of maintenance-free operation.

Frequently Asked Questions
How much Flash memory does PIC18LF8527-I/PT offer and how does this compare to smaller PIC18 variants?
PIC18LF8527-I/PT provides 48 KB of on-chip Flash, which is 3× the 16 KB found in entry-level PIC18 devices. This capacity supports full TCP/IP stacks, multi-protocol firmware, and large lookup tables needed in energy-metering or industrial gateway applications without requiring external memory.
What minimum supply voltage does PIC18LF8527-I/PT support and how does it benefit battery-powered meter designs?
PIC18LF8527-I/PT operates from a minimum of 2.0 V at 4 MHz, allowing continued operation as lithium or alkaline batteries discharge toward end-of-life. Combined with XLP sleep currents below 100 nA, an energy meter running periodic 15-minute data acquisition cycles can sustain over 10 years on a 3.6 V lithium D-cell without battery replacement.
How many I/O pins does the TQFP-80 package expose and how are they allocated in a typical industrial application?
The TQFP-80 package exposes up to 70 general-purpose I/O pins across multiple ports with 0.5 mm pitch. A typical industrial controller allocates 16 pins to ADC inputs for analog sensor channels, 8 pins to SPI and I2C buses, 4 pins to UART communication, and the remaining pins to digital I/O for relay drivers, status LEDs, and keypad scanning.
Is PIC18LF8527-I/PT a suitable upgrade path from 64-pin PIC18 MCUs for firmware teams expanding I/O requirements?
Yes, PIC18LF8527-I/PT is a natural upgrade from 64-pin PIC18 devices because it preserves PIC18 instruction set compatibility while adding 16 additional I/O pins, 12 KB more Flash, and a larger 20-bit address bus. Migration requires only a PCB respin to accommodate the 80-pin TQFP footprint, and existing firmware compiles without modification under MPLAB X IDE with XC8 compiler targeting the new device.
