The part integrates 2 KB of RAM, 1 KB of EEPROM, and 69 digital I/O pins, plus an integrated LCD driver, nanoWatt XLP low-power technology, and a Charge Time Measurement Unit (CTMU) peripheral. What is a PIC18 8-bit microcontroller? PIC18 is Microchip's enhanced 8-bit RISC architecture family built on a modified Harvard bus, sitting between the PIC16 baseline line and the 16-bit dsPIC/PIC24 families in the company's 8-bit/16-bit MCU portfolio. PIC18F devices add a wider instruction set, hardware multiply, priority levels for interrupts, and richer peripherals (USB, CAN, LCD, CTMU, mTouch capacitive touch) while remaining code-compatible with PIC16 projects through a unified MPLAB X toolchain. Key features of the PIC18F85K90-I/PTRSL include nanoWatt XLP technology for ultra-low sleep current, an on-chip LCD driver with up to 192 segments, 12-bit ADC, multiple Enhanced Capture/Compare/PWM (ECCP) modules, and standard serial interfaces (I2C, SPI, UART/USART). The CTMU module enables capacitive touch sensing and precision time measurement, while the integrated LCD controller removes external display driver ICs from low-power meter designs. The internal oscillator block supports operation from 31 kHz to 16 MHz, with a 4x PLL option that reaches 64 MHz system clock. Brown-out Reset (BOR), Power-On Reset (POR), and Watchdog Timer (WDT) provide robust fault recovery. The wide 1.8V to 5.5V operating range covers both 3.3V and 5V supply rails used in industrial and consumer LCD products. Typical applications include battery-powered e-meter and utility metering front-ends, white-goods and appliance HMI panels with LCD, capacitive touch button interfaces, medical infusion pumps with segment displays, and handheld industrial terminals. The combination of low-power sleep, on-chip LCD bias generation, and mTouch capacitive sensing makes it a strong fit for battery-form-factor products that need a display and touch without an external touch controller. Design consideration: when migrating from a PIC18F87K90 sibling to this 32 KB Flash variant, confirm application code fits within 32 KB and that EEPROM usage is within the 1 KB budget. For tighter BOM cost, the PIC18F65K90 family shares peripherals in a smaller 64-pin TQFP.

PIC18F85K90T-I/PT

PIC18F85K90T-I/PT - 8-bit 64MHz 32KB Flash LCD MCU | Microchip

The Microchip Technology PIC18F85K90T-I/PT is an 8-bit PIC18 microcontroller built on nanoWatt XLP technology, integrating 32KB (16K x 16) of Flash program memory and targeting 64/80-pin high-performance applications with on-chip LCD drivers. The device runs at up to 64 MHz and is housed in an 80-pin TQFP (PT) 12x12 mm package. It belongs to the PIC18F85K90 family, which also includes the 80-pin PIC18F86K90 and PIC18F87K90 variants with progressively larger memory footprints. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash/ROM), data memory (RAM), and programmable peripherals. The PIC18F85K90 is a Harvard-architecture 8-bit RISC device, meaning the program and data buses are physically separate and a single instruction executes per clock cycle (except for branches). The '85K90 family' designation indicates an LCD-segment driver family with nanoWatt XLP extreme-low-power technology, while the wider PIC18F family hierarchy spans PIC10/12/16/18 8-bit cores upward into PIC24/dsPIC 16-bit cores and PIC32 32-bit MIPS cores. Key features of the PIC18F85K90T-I/PT include 2KB of RAM, 1KB of EEPROM data memory, an integrated LCD driver supporting up to 384 segments (with on-chip charge pump), a 12-bit ADC with up to 24 channels, and the Charge Time Measurement Unit (CTMU) module for capacitive touch sensing. Additional peripherals include multiple Enhanced USART, SPI, I2C, PWM, and a Real-Time Clock Calendar (RTCC). The 'T' suffix indicates Tape & Reel packaging, the 'I' denotes the industrial -40C to +85C temperature range, and the '/PT' suffix specifies the 80-pin TQFP package. The device's nanoWatt XLP technology delivers sleep currents as low as 20 nA, making the family well-suited to battery-powered products. The CTMU peripheral uses a constant-current source plus analog I/O to measure capacitance, enabling up to 24 channels of capacitive touch buttons, sliders, or proximity sensors without an external touch controller. The combination of large segmented LCD, capacitive touch, ultra-low-power sleep, and high-pin-count packages is the central reason this family exists. Typical applications include battery-powered medical instruments (glucose meters, blood-pressure monitors), home and industrial thermostats, white-goods user interfaces (washing machines, ovens), fitness wearables with LCD readouts, metering equipment (utility, gas, water), and any human-machine interface that combines a segmented LCD with capacitive touch buttons. The wide operating voltage range (typically 1.8V-3.6V with full-speed operation down to 2.0V, depending on configuration) supports single-cell Li-ion or two-coin-cell battery chemistries. When designing with this part, note that the 'T' suffix is a packaging code only - functionally the PIC18F85K90T-I/PT is identical to PIC18F85K90-I/PT. Also, code written for the PIC18F85K90 will run unchanged on the PIC18F86K90 / PIC18F87K90 (more Flash, same peripherals) and vice versa, which simplifies in-family migration. The CTMU pinout overlaps with standard ADC channels, so capacitive-touch design must be coordinated with the analog channel allocation in the pin manager.

The 80-pin TQFP footprint exposes 69 I/O pins to the PCB. Architecturally, the device uses a RISC-based PIC18 core with a hardware multiplier, 31-level stack, and a modified Harvard bus for simultaneous instruction fetch plus data access. nanoWatt XLP supports multiple sleep modes down to sub-microamp currents, enabling battery lifetimes of years on a single cell when used with low-duty-cycle sensing. Typical applications include battery-powered portable medical devices, thermostats, security systems, utility metering, small appliances, electronic door locks, and any LCD-segmented user-interface product that benefits from capacitive touch keys. The wide peripheral mix also suits general industrial control. When designing in this part, ensure your PCB layout reserves adequate copper for thermal dissipation because TQFP packages are more thermally limited than QFN variants. Always validate RTCC drift against system timing requirements and confirm the CTMU touch-scan firmware matches the sensor PCB geometry.

Key features of the PIC18F8627-I/PT include nanoWatt power-management technology with multiple idle and sleep modes, a hardware 8x8 multiplier, a 16-bit wide instruction word, ICD/ICSP in-circuit debugging, and industrial temperature grade operation (-40C to +85C). The wide 2.0V to 5.5V Vdd range and low-power sleep modes make it attractive for both line-powered and battery-backed designs. The internal oscillator block provides configurable 8 MHz to 32 MHz operation, reducing external component count. Architecturally, the PIC18F8627-I/PT uses an enhanced flash memory cell that supports >10k erase/write cycles and >40-year data retention, with self-programmability under firmware control for bootloader-style field updates. The 10-bit ADC delivers up to 16 channels of conversion with a 100K samples/second aggregate rate, and the CTMU (Charge Time Measurement Unit) enables touch sensing and precise time-of-flight measurements. Typical applications include industrial automation controllers, HVAC and building-management systems, automotive body and instrument-cluster ECUs, embedded CAN-node interfaces, motor-control front-ends, and consumer white-goods main controllers. The combination of CAN + multiple serial ports + abundant I/O positions it well for distributed control networks. Design consideration: at 80 pins the TQFP footprint requires a 4-layer PCB for clean signal routing, and unused I/O must be configured as outputs or pulled to defined states to minimize current draw.

PIC18F86J16T-I/PT - 8-Bit PIC18 MCU, 96KB Flash, 80-TQFP

The Microchip Technology PIC18F86J16T-I/PT is an 8-bit PIC18J-series microcontroller running up to 48 MHz (12 MIPS at 3V), integrating 96 KB of Flash program memory and 3,936 bytes of RAM in an 80-pin TQFP (12x12 mm) package. It provides 70 general-purpose I/O lines, 16-bit data-bus architecture, and operates from a 2.0 V to 3.6 V supply with 5V-tolerant digital inputs. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (Flash), volatile data memory (RAM), and configurable peripherals on one die. The PIC18 family is Microchip's high-performance 8-bit line, sitting hierarchically between baseline PIC10/12/16 MCUs and the 16-bit dsPIC/PIC24 families. PIC18J parts target low-voltage (1.8V-3.6V) cost-sensitive designs with 5V-tolerant I/O for mixed-signal boards. Key features include parallel master port (PMP), two I²C/SPI and two asynchronous serial ports, 10-bit ADC, nanoWatt power management, internal 8 MHz oscillator, enhanced ICD with three hardware breakpoints, and 10,000 Flash endurance cycles with 20-year retention. The 16-bit instruction path keeps throughput high while retaining the 8-bit register file. The PIC18J core uses a Harvard architecture with separate Flash and RAM buses, achieving 12 MIPS at 48 MHz from a single 3.3V rail. On-chip peripherals (PMP, MSSP, USART, ADC, comparators) share an internal peripheral bus, and DMA-style data-mover hardware accelerates repetitive transfers without CPU intervention. Typical applications include industrial control panels, USB peripherals, graphic LCD/PMP driver boards, sensor aggregation hubs, automotive body and HMI modules, and low-cost consumer appliances. The 5V-tolerant digital inputs simplify interfacing to legacy 5V sensors and keypads. When designing with this MCU, ensure the 5V-tolerant pins are configured correctly and that decoupling is placed close to VDD/VSS pairs. The internal 8 MHz oscillator saves BOM cost but is less accurate than an external crystal; pick an external crystal if you need USB-LS or CAN timing margins.

The Microchip PIC18F86J50T-I/PT is a high-performance 8-bit PIC18J microcontroller with integrated full-speed USB 2.0 transceiver, 64KB (32K x 16) of Flash program memory, and a 12 MIPS 48MHz internal oscillator, packaged in an 80-pin TQFP (12x12 mm). It supports 70 digital I/O pins across multiple ports, executes one instruction per clock cycle, and operates from 4.2V to 5.5V with nanoWatt power-management technology for battery-friendly sleep currents. The part is supplied in tape-and-reel packaging (the "T" suffix) for high-volume production lines. What is a PIC18J microcontroller? An 8-bit RISC microcontroller is a small computer-on-a-chip that uses a Harvard architecture with separate program and data buses, executes most instructions in a single clock cycle, and is widely used in embedded systems requiring deterministic real-time control. PIC18J extends the PIC18 family by adding an internal voltage regulator that allows single 3.3V operation while keeping flash programming voltage on-chip, simplifying designs targeting USB, graphics, and connectivity. Within the broader taxonomy, PIC18J belongs to: microcontroller -> embedded MCU -> RISC processor -> semiconductor IC. Key features include an integrated USB 2.0 full-speed transceiver (12 Mbps) with on-chip 3.3V regulator, 70 I/O pins with peripheral pin select flexibility, a 10-bit ADC with up to 12 channels, two USART modules, two MSSP (SPI/I2C) modules, and three CCP/ECCP modules for PWM/motor control. The Enhanced Flash Controller supports self-programming and a 128-byte data EEPROM is provided for non-volatile user storage. The 12 MIPS core executes instructions at 48 MHz from the internal PLL. Typical applications include USB peripherals (HID, CDC, mass storage, audio), industrial control panels with TFT/graphical LCDs, sensor data acquisition hubs, low-cost instrumentation with USB connectivity, and embedded web/configuration interfaces. Designers select the PIC18F86J50T when they need 64KB of code space, full-speed USB without an external transceiver, and a large pin count for parallel buses, displays, or matrix keypads. When designing with this part, ensure the internal 3.3V regulator's bulk capacitance requirements are met per the datasheet, and budget approximately 5 KB of Flash for the USB stack. Use the TQFP-80 land pattern and follow Microchip's USB hardware design guide for impedance-controlled D+/D- traces.

The Microchip Technology PIC18F86J55-I/PT is an 8-bit PIC18 microcontroller IC running at 48 MHz, integrating 96 KB (48K x 16) of Flash program memory and 3.936 bytes of RAM in an 80-pin TQFP (12x12 mm) package. It features an integrated Full-Speed USB 2.0 (12 Mbit/s) peripheral alongside MI²C/SPI (up to 10 Mbit/s) and a LIN-capable EUSART, giving it four serial ports in a single chip. An 8-bit microcontroller (MCU) is a programmable integrated circuit that executes instructions from internal Flash memory using an 8-bit data path. It belongs to the microcontroller family within the broader semiconductor hierarchy: microcontroller -> embedded processor -> integrated circuit -> semiconductor. The PIC18F86J55 belongs to Microchip's PIC18J sub-family, distinguished by low-voltage (2.5V/3.3V) operation, integrated USB 2.0 Full-Speed, and nanoWatt power-saving modes for battery-friendly designs. Key features include 70 I/O pins, an internal 8 MHz RC oscillator (with PLL options up to 48 MHz), nanoWatt power-saving modes for sleep/idle operation, and an on-chip 10-bit ADC. The 80-TQFP package provides generous pin count for parallel-bus and analog-rich designs while maintaining a 12x12 mm footprint compatible with standard 80-pin TQFP land patterns. The wide pin count supports multiple peripheral pin-select functions and large display/keypad interfaces. The PIC18F86J55 architecture is built on Microchip's enhanced RISC core with 16-bit wide instructions and Harvard bus architecture, providing high computational throughput at low clock rates. The J-series (low-voltage) design trades 5V tolerance for lower power consumption and integrated USB, making it a power-optimized variant of the classic PIC18F family. Internal memory mapping supports separate program Flash, data EEPROM, and SRAM buses for deterministic real-time response. Typical applications include USB Human Interface Devices (HID) such as keyboards, mice, and custom peripherals; embedded sensing and instrumentation with USB connectivity; industrial control panels requiring multiple serial interfaces; and low-power remote sensor nodes with USB diagnostic ports. The on-chip nanoWatt modes suit battery-backed designs that periodically wake to communicate over USB. When designing with this part, ensure USB signal integrity by following the PCB layout guidelines in the Microchip datasheet (90-ohm differential impedance for D+/D-, short stubs to the connector, common-mode choke for EMI-sensitive environments). Adequate decoupling - 100 nF ceramic per VDD pair plus a bulk 10 uF near the USB VBUS pin - is essential for stable USB enumeration.
