PIC18F86K90-I/PTRSL 개요
A microcontroller (MCU) is a single-chip computer that combines a CPU core, non-volatile program memory (Flash), volatile data memory (RAM), and a rich set of peripheral IP such as timers, ADC, communications controllers, and I/O. Within the broader taxonomy, the PIC18F86K90 belongs to the 8-bit MCU family -> PIC18 sub-family -> PIC18FxxK90 LCD-driver family -> PIC18F8xK90 80-pin members. It targets battery-powered LCD applications that combine touch sensing, segmented display driving, and ultra-low standby current in the same silicon.
Key features include nanoWatt XLP™ technology for deep-sleep currents measured in nanoamps, an integrated LCD driver supporting up to 192 segments, a Charge Time Measurement Unit (CTMU) that enables capacitive touch and simple temperature measurement, 24 channels of 12-bit ADC, multiple UART/SPI/I²C interfaces, and an operating voltage range of 1.8V to 5.5V. The 'I' temperature grade denotes an industrial -40°C to +85°C operating range, and 'PTRSL' indicates the 80-pin TQFP (PT) package shipped in tape-and-reel (TR) orientation with SL suffix marking.
Architecturally, the device uses an enhanced Harvard RISC core with a hardware multiplier, 31-level stack, and a C-friendly instruction set, allowing efficient C compilation through Microchip's MPLAB XC8 toolchain. The 80-pin TQFP exposes the full peripheral set: ample digital I/O, the full LCD segment bus, and CTMU-driven touch channels, which is why designers typically pick the 80-pin variants over the 64-pin PIC18F66K90 family members when the application needs more glass real-estate and more touch keys.
Typical applications include battery-powered medical devices such as glucose meters and portable patient monitors, industrial panel meters and process transmitters with LCD readouts, home appliances with segment displays, security keypads with capacitive touch, and consumer devices requiring long battery life combined with on-glass graphics. The CTMU simplifies touch-interface designs by measuring capacitance changes without an external analog front end.
When designing with this part, allocate the lower 16 addresses of Flash for the interrupt vector table and use MPLAB XC8 PRO mode for code-density. For LCD applications, follow Microchip's AN658 LCD fundamentals application note for bias and contrast resistor selection, and verify that the segment and common pin assignments fit within the 192-segment maximum of the 80-pin package. Industrial users should confirm the 'I' suffix (-40°C to +85°C) versus the 'E' (-40°C to +125°C) variant when targeting harsher environments.

설계 노트
Estimated: at 64MHz active, the PIC18F86K90-I/PTRSL core draws roughly 8-12 mA from 3.3V, dominated by the LCD driver and I/O switching. In Sleep mode with nanoWatt XLP™ enabled, current drops to under 100 nA typical, allowing multi-year battery life in metering applications. Use the Microchip MPLAB XC8 POWER_DEBUG plugin and AN1414 to characterize your actual application current before committing to a battery chemistry.
Decouple VDD with a 100 nF ceramic placed within 5 mm of each VDD/AVDD pin pair, plus a bulk 10 µF tantalum or ceramic. The LCD driver charge-pump output (VLCD) and bias pins (LCDBIASx) need their own 100 nF capacitors close to the pins per application note AN658. Use a star-ground topology tying AGND to DGND at a single point beneath the IC, and keep the high-frequency MCU traces away from the LCD glass connector.
Do not skip the configuration bits (CONFIG1L-3H) or set the wrong oscillator mode - the device defaults to internal oscillator but defaults may not be optimal for USB or timing-critical peripherals. Verify the Vcap pin (if present in your package variant) has a 10 µF capacitor, and confirm the LCD segment/common pin assignments do not collide with CTMU touch channels when both features are used simultaneously on the same pin. Always check the latest PIC18F87K90 silicon errata (DS80000542) for known anomalies before locking the PCB layout.
When driving longer traces to the LCD glass (typically a 1-3 cm flex cable), add 1-10 kΩ series resistors on each segment line to dampen overshoot from the high-impedance LCD outputs. For CTMU touch channels, keep the touch electrode traces short, guarded by a ground plane, and away from switching signals. The Microchip AN1250 CTMU application note gives PCB layout guidelines for robust capacitive touch sensing.
