PIC18F86J55T-I/PT

PIC18F86J55T-I/PT - 96KB Flash USB MCU 8-Bit 48MHz TQFP-80

The Microchip Technology PIC18F86J55T-I/PT is an 8-bit PIC microcontroller in the PIC18J family, featuring 96KB (48K x 16) of Flash program memory, 3.8KB of RAM, and an integrated Full-Speed USB 2.0 device controller, all housed in an 80-pin TQFP (12x12 mm) package. It operates at up to 48MHz (12 MIPS) from a 2.0V to 3.6V supply and targets applications that need both connectivity and low power consumption via the nanoWatt technology suite. A microcontroller (MCU) is an integrated circuit containing a CPU, memory, and programmable peripherals. The PIC18J family is built on an enhanced Harvard architecture with a RISC-style instruction set, providing deterministic interrupt response and single-cycle instruction execution for embedded control. MCUs sit at the lowest tier of the embedded processor hierarchy - above simple logic ICs, below microprocessors - and are the workhorse components for almost every connected product today. Key specifications include 4KB of buffer RAM used by the USB endpoint system, 66 general-purpose digital I/O pins, two analog comparators, a 10-bit ADC with up to 16 input channels, two CCP/ECCP modules, two EUSART ports (LIN-capable), one MSSP port that supports both SPI (up to 10 Mbit/s) and I2C, and an internal 31 kHz to 8 MHz oscillator block. The device integrates a charge time measurement unit (CTMU) for capacitive touch and a real-time clock calendar with on-chip 32 kHz oscillator support. Architecturally, the PIC18F86J55 uses a wide 16-bit instruction path with separate program and data buses, allowing single-cycle fetches even while accessing data memory. The on-chip USB 2.0 Full-Speed transceiver eliminates the need for an external PHY, and the 4KB dedicated buffer RAM ensures USB throughput without starving user RAM. The nanoWatt features include Idle, Sleep, and deep-sleep modes with current as low as nanoampere-class levels when peripherals are gated off individually. Typical applications include USB peripherals such as HID input devices and CDC serial bridges, embedded web and sensor interfaces with USB charging, industrial data loggers, automotive body controllers (LIN/J2602 nodes), home automation gateways, and low-power instrumentation with capacitive touch user interfaces. The wide 2.0V to 3.6V range also makes it suitable for single-cell Li-ion powered designs. When designing with this part, plan the power-rail decoupling carefully: place a 100 nF ceramic on every VDD/AVDD pair, keep the USB D+/D- traces length-matched within 2 mm, and route the 48 MHz crystal traces short and guarded. The USB pull-up resistor on D+ must be enabled in firmware for proper enumeration. For low-power Sleep mode, gate off unused peripherals and use the RTCC with its dedicated 32 kHz crystal for sub-microamp standby. This page synthesizes distributor pricing, parametric drop-in alternatives within the same 80-TQFP footprint, and practical design notes that complement - and extend - the information found in the manufacturer datasheet.

PIC18F86J72T-I/PT

PIC18F86J72T-I/PT - 8-bit 48MHz Energy Meter MCU 64KB Flash TQFP-80 | Microchip

The Microchip Technology PIC18F86J72T-I/PT is an 8-bit PIC18J-family microcontroller engineered for single-phase smart energy meters and energy monitors, integrating a dual-channel 16/24-bit analog front end (AFE), a 12-bit 12-channel SAR ADC, a 132-segment LCD driver, 64KB Flash program memory, 4KB RAM, hardware RTCC, and CTMU module in an 80-pin TQFP (12x12 mm) package. The device operates at up to 48 MHz across a 4.2 V to 5.5 V supply range (2.5 V/3.3 V core variants exist in the family). Key differentiating features include the on-chip 16/24-bit sigma-delta AFE which eliminates an external energy-metering ASIC, the integrated 132-pixel LCD controller that removes an external LCD driver, and the CTMU (Charge Time Measurement Unit) enabling touch and capacitive sensing for user interfaces on the meter. A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and programmable I/O peripherals on one die. The PIC18F family is Microchip's 8-bit RISC architecture family, with the 'J' suffix indicating 2.5 V/3.3 V core operation (lower-voltage variants of the PIC18 line) and 'F' indicating Flash program memory. The PIC18F86J72 sits within the Microchip hierarchy of MCU -> 8-bit MCU -> PIC18 family -> PIC18F sub-family -> PIC18F8xJ72 energy-meter series -> PIC18F86J72 (64KB Flash variant). PIC18J devices use a 16-bit instruction set optimized for C-code density and low power, with hardware multipliers and a deterministic interrupt structure. Functionally, the PIC18F86J72 combines metrology-class analog (16/24-bit AFE) with general-purpose digital control in one package. The dual-channel AFE supports current and voltage sensing for Class 0.2/0.5 meters, and the SAR ADC handles auxiliary analog signals. The hardware RTCC (Real-Time Clock/Calendar) tracks time-of-use tariff schedules without software overhead. CTMU enables touch buttons or proximity sensing. The 64KB (32K x 16) Flash supports 100K+ erase/write cycles typical for firmware updates. The 80-pin TQFP package provides 70 user I/O pins for keypad, LCD segment pins, communication ports, and metrology front-end connections. Typical applications include single-phase smart electricity meters (Class 1 / Class 0.5), multi-function energy monitors, smart plug power meters, solar PV inverters with display, and industrial power-quality analyzers. The integrated AFE + LCD eliminates the separate metering and LCD-driver ICs found in legacy designs, reducing BOM cost and PCB area. The wide operating temperature range (-40C to +85C for the 'I' industrial grade) supports outdoor and industrial cabinet installations. Designers should budget PCB area for the 12x12 mm TQFP-80 footprint with 0.5 mm pitch, requiring 4-layer PCB and standard SMT assembly. Programming via ICSP requires dedicated RB6/RB7 pins, and debugging uses ICD/ICSP. ESD-sensitive signals (AFE inputs, LCD outputs) require proper guarding and creepage on the PCB to meet IEC 62053-21 metering standards. Bootloader space should be reserved when using the dual-image Flash feature for OTA firmware updates.

PIC18F86J90-I/PT

PIC18F86J90-I/PT - 8-Bit 48MHz 64KB Flash LCD MCU | Microchip

The Microchip Technology PIC18F86J90-I/PT is a 8-bit PIC18J microcontroller IC operating at up to 48 MHz with 64 KB of Flash program memory and 4 KB of RAM, housed in an 80-pin TQFP (12x12 mm) package. The device integrates a segmented LCD driver, nanoWatt Technology power management, and a broad peripheral set targeting human-machine interfaces and metering. According to the Microchip product page, the "86J90" denotes the 64-pin/80-pin LCD PIC18 family with 64 KB Flash and 4 KB RAM, with the -I/PT suffix indicating industrial temperature range (-40C to +85C) in the TQFP surface-mount form. An 8-bit microcontroller (MCU) is a microprocessor core with an 8-bit data path, integrated program memory (Flash/ROM), data memory (RAM), and on-chip peripherals including timers, communication interfaces, and analog blocks. PIC18 microcontrollers follow Microchip's enhanced Harvard architecture, sitting within the broader hierarchy of microcontroller -> embedded MCU -> semiconductor device. The J-suffix indicates an ultra-low-power variant of the PIC18 family, designed with nanoWatt features such as multiple idle modes, low-power Timer1 oscillator, and dynamic switching between primary and timer-based clock sources for battery operation. Key differentiating features include 70 I/O pins, an integrated segmented LCD controller with programmable bias and contrast, two USART modules, two MSSP (I2C/SPI) modules, a 12-bit A/D converter, and nanoWatt Technology for reduced sleep current. The 64 KB Flash (32K x 16) supports self-programmability and data EEPROM emulation, while the 4 KB RAM provides ample headroom for LCD buffer and communication stacks. Supply voltage is 4.2 V to 5.5 V as called out in the DigChip parametric record. From an architectural standpoint, the PIC18F86J90 uses a 16-bit instruction word with a modified Harvard structure, giving 8 MHz instruction throughput per MIPS at the oscillator input and an instruction-cycle time of 4 oscillator cycles. Its 12-bit ADC and Capture/Compare/PWM modules make it well suited to mixed-signal metering and motor-control-class UI boards, while the parallel master port allows external memory expansion where the on-chip 64 KB Flash is insufficient. The -I temperature grade targets industrial environments, and the -PT package designation specifies the 12x12 mm TQFP-80 footprint used throughout the 80-pin PIC18F LCD family. Typical applications include handheld meters (multi-parameter measurement with on-device LCD), thermostats and HVAC controllers, home security panels, portable medical devices, and utility metering products. The integrated LCD driver eliminates the need for an external display controller, simplifying BOM and PCB area in user-interface products that must display numerical readings or icons without a graphical TFT. When designing with this MCU, allocate pin functions around the LCD segment allocations first; the segment lines share pins with general I/O and must be planned as a group before assigning pushbuttons, ADC inputs, or communication lines. The 4.2 V minimum supply rules out direct 3.3 V-only boards, so a boost or LDO is required when sourcing from a single Li-ion cell. Pair the MCU with a Microchip-compatible ICD or debugger (e.g., PICkit 3 or MPLAB ICD 4) using the ICSP interface.

The part runs at up to 64MHz (16 MIPS) and is built on Microchip's nanoWatt XLP™ ultra-low-power process, making it suitable for battery-powered applications that also need a segmented LCD glass. 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.

What is a PIC18F microcontroller? The PIC18F family is Microchip's flagship 8-bit Enhanced FLASH MCU architecture, sitting in the hierarchy: PIC18F -> 8-bit MCU -> microcontroller -> embedded controller -> semiconductor. It uses a 16-bit instruction word with an 8-bit data path, 31-level hardware stack, hardware multiply (8x8 in one cycle), and a vectored interrupt controller with prioritized interrupts. Compared with the older PIC16F baseline family, PIC18F adds linear memory addressing, larger RAM/Flash, and richer peripherals, making it suited to connectivity-rich and human-machine-interface applications. Key differentiating specifications of the PIC18F8720 include: 128KB self-programmable Flash (in-application programmable via ICSP), 3840 bytes SRAM, 1024 bytes EEPROM, two enhanced USARTs, one MSSP supporting both SPI master/slave and I2C master/slave, a 10-bit ADC with up to 16 channels (device-dependent), five 16-bit timer/counters, two capture/compare/PWM modules, and a 16-bit Parallel Slave Port for external memory or FPGA interfaces.

Designers should pay attention to the 4.2 V minimum VDD, the dual oscillator pins (RA6/OSC1, RA7/OSC2) supporting crystal or external clock, and the dedicated MCLR/VPP reset pin. Decoupling requires a 0.1 uF ceramic on VDD close to the package plus a 10 uF bulk capacitor near the analog supply pin (AVDD) when the ADC is used. For new designs, Microchip recommends the PIC18F K-series, but the PIC18F8720T-I/PT remains the drop-in choice for existing 80-pin TQFP layouts.

The Microchip PIC18F87J50-I/PT is an 8-bit PIC18 microcontroller built around a RISC architecture with 128KB (64K x 16) of on-chip Flash program memory, 4KB of RAM, and an integrated Full-Speed USB 2.0 device peripheral, housed in an 80-pin TQFP (12x12 mm) package. It operates at up to 48MHz from a 3.3V supply (typically 4.2V to 5.5V per the simplified datasheet record) and is targeted at full-speed USB 2.0 and low-speed USB 1.1 designs that need substantial code space and I/O density. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, RAM, non-volatile program memory, peripherals, and I/O on one die; within Microchip's taxonomy the PIC18 family sits above the baseline PIC10/12/16 series and below the PIC24/dsPIC parts, while the J-suffix '18J' family specifically supports low-voltage 3.3V operation with nanoWatt power-saving modes for embedded connectivity. Key features include 70 digital I/O pins, four serial communication ports (FS-USB at 12 Mbps, I2C/SMI, SPI up to 10 Mbps, and two LIN-capable EUSART channels), an integrated 10-bit ADC, nanoWatt sleep and idle modes, an on-chip 3.3V regulator, and an enhanced flash-memory controller supporting self-programmability. The 80-pin TQFP exposes the parallel data/address bus, giving the part both pin-rich MCU behavior and external-memory expansion capability. The CPU is a Harvard-style RISC core with single-cycle instruction execution that delivers approximately 10 MIPS at 48MHz, while the on-board 3.3V internal regulator lets designers run the core from a 5V rail without an external LDO. The internal Full-Speed USB SIE handles the USB protocol in hardware, eliminating the need for an external PHY and reducing BOM cost on USB peripherals. Typical applications include USB HID/CDC peripherals, USB-to-UART bridges, industrial sensor data loggers, automotive LIN nodes, and embedded gateways that need multi-protocol serial connectivity. It is also widely used in educational and development boards (such as the PIC18F87J50 FS USB Demo Board) that demonstrate USB device-class firmware. When designing with the PIC18F87J50, reserve at least one decoupling 0.1 uF ceramic capacitor per power pin plus a 10 uF bulk near the regulator output, and route the USB DP/DM pair as a 90-ohm differential trace to maintain Full-Speed signal integrity.

Industrial temperature range is -40C to +85C and the device runs from a single 2.0V-3.6V supply. The 80-pin TQFP exposes up to 69 digital I/O lines, providing generous expansion headroom for sensors, actuators and user interfaces. Architecturally, the PIC18F87J60 uses the proven PIC18J pipeline with single-cycle execution at 41.667 MHz (4x PLL from 10 MHz), 16-bit opcodes and a hardware multiply. The on-die PHY interfaces directly to a 1:1 magnetics and RJ-45 jack, while the MAC implements IEEE 802.3 with the Microchip TCP/IP stack (MLA) supplying the upper layers. Hardware crypto acceleration, RTCC and 4 KB of EEPROM emulation complete the feature set. Typical applications include industrial automation nodes (sensor hubs, PLC companions, Modbus/TCP gateways), building automation (BACnet/IP thermostats, lighting controllers, access readers), remote monitoring (energy meters, environmental sensors), point-of-sale terminals and networked medical instruments where wired Ethernet is preferred over Wi-Fi for reliability and security. The integrated PHY also makes it a strong fit for low-cost IoT edge gateways. When designing with the PIC18F87J60, reserve a contiguous region of RAM for the Ethernet transmit/receive buffers and place the 1:1 isolation magnetics within 25 mm of the differential pair to meet IEEE 802.3 return-loss limits. Bulk + 0.1 uF + 0.01 uF decoupling on every VDD/VSS pair and a 4-layer ground plane are recommended by the Microchip Ethernet reference design.

The Microchip Technology PIC18F87J72-I/PT is a high-performance 8-bit PIC18 microcontroller engineered for single-phase energy meter and multi-function monitoring applications, integrating a dual-channel 16/24-bit delta-sigma analog front end (AFE) and a 12-bit 12-channel SAR ADC alongside an on-chip segmented LCD controller. The device executes instructions at 48 MHz internal clock (up to 12 MIPS) and is housed in an 80-pin TQFP (PT) package measuring 12x12 mm with 1.0 mm height. It includes 128 KB of Flash program memory (64K x 16), 4 KB of RAM, a hardware Real-Time Clock and Calendar (RTCC), and the Charge Time Measurement Unit (CTMU) for capacitive touch and temperature sensing. A microcontroller (MCU) is a single-chip computer containing a CPU core, program and data memory, and integrated peripherals designed to execute embedded firmware in a standalone system. The PIC18 family sits within Microchip's 8-bit PIC architecture hierarchy, which scales from baseline PIC10/PIC12/PIC16 devices up to high-performance PIC18 parts, ultimately forming the foundation of the broader 32-bit PIC32 line. Energy-metering MCUs combine precision analog signal chains with computation and display driving in a single die, eliminating the need for separate metrology ADCs and LCD driver ICs. Key features include 70 digital I/O pins, dual USART, SPI, I2C, 132-pixel segmented LCD driver with dedicated charge pump, two op-amps inside the AFE, hardware multiplier, and nanoWatt power management for sleep-mode current below 1 uA. The 24-bit sigma-delta AFE delivers better than 0.1% accuracy across the dynamic range required for IEC 62053-21 / IEC 62053-22 single-phase electricity meters. The PIC18F87J72 architecture uses an enhanced RISC core with hardware multiply, 16-bit-wide Flash memory bus, and an internal 8 MHz oscillator (PLL-able to 48 MHz). The dual-channel AFE block pairs a programmable-gain amplifier (PGA) with a 16-/24-bit sigma-delta modulator; combined with the 12-bit SAR ADC (12 channels, 100 ksps) the device can simultaneously sample voltage and current while driving the LCD. Typical applications include single-phase and multi-function electricity meters, smart energy monitors with segmented LCD, power-quality analyzers, solar PV monitoring, industrial process instrumentation, and capacitive-touch user interfaces using the CTMU. The wide operating range (2.0 V to 3.6 V core, 4.2 V to 5.5 V with 5V-tolerant I/O variant noted in datasheet) supports battery-backed metering with line-powered LCD operation. When designing with this part, allocate PCB area for two differential current-sensor inputs (typically current transformers or shunt resistors) routed to the dedicated SDx/SDy sigma-delta channels with anti-aliasing filters. Decouple VDD/VSS with 100 nF ceramic at each supply pin and provide a local bulk 10 uF for the LCD charge pump; refer to the Microchip energy-meter reference design for the full metrology calibration flow.

PIC18F87J72T-I/PT - 128KB Flash LCD MCU w/ AFE | Microchip

The Microchip Technology PIC18F87J72T-I/PT is an 8-bit PIC18J RISC microcontroller integrating a dual-channel 16-/24-bit Analog Front End (AFE), a 12-bit 12-channel SAR ADC, and a 132-pixel LCD driver, all in an 80-pin TQFP package. The device delivers 128 KB Flash program memory, 4 KB RAM, and executes instructions at up to 48 MHz (10 MIPS typical) from a 2.5V/3.3V supply domain (operating range 2.0V–3.6V per PIC18J family, with PIC18F87J72 datasheet noting 4.2V–5.5V core tolerance on some revisions). Its integrated dual-channel AFE with 16-/24-bit sigma-delta modulator interface, plus CTMU and hardware RTCC, makes this part purpose-built for single-phase multi-function energy meters, smart e-Meters, and power-monitoring front-ends. A microcontroller (MCU) is a single-chip computer containing a CPU core, program/data memory, peripherals, and I/O on one die. The PIC18F87J72 belongs to the 8-bit RISC PIC18 family, which uses a 16-bit instruction word with 8-bit data paths. Within the broader taxonomy, this device sits in the sub-hierarchy: PIC18F87J72 -> PIC18J -> PIC18 -> PIC microcontrollers -> 8-bit MCU -> microcontroller -> embedded processor -> semiconductor. Its nanoWatt technology pedigree positions it for low-power metering that must remain in sleep for years on a battery-backed RTC. Key features include 70 user I/O pins, an internal 31 kHz and configurable oscillator, hardware CTMU for capacitive touch and time measurement, RTCC with timestamp, and an LCD driver supporting up to 132 pixels directly. The integrated AFE accepts external sigma-delta modulators for current and voltage channels, eliminating external ADC ASICS and shrinking the meter BOM. According to Microchip product literature, the part is targeted at multi-function single-phase smart energy meters that combine metrology, tamper detection, and an on-board display. From an architecture perspective, the PIC18J core delivers single-cycle instruction execution with hardware multiply, a 16-level stack, and linear memory addressing across program and data spaces. The 12-channel 12-bit SAR ADC complements the dedicated AFE by providing auxiliary measurements such as temperature or battery voltage. The LCD controller supports static, 1/2, 1/3, and 1/4 multiplex with software-controlled contrast, removing the need for an external display driver. Typical applications are single-phase multi-function smart energy meters, power-quality monitors, smart-grid endpoints with on-device LCD, and tamper-detection metering nodes. The wide I/O count and integrated display also suit industrial HMI panels and battery-backed instrumentation. A critical design consideration is the use of the internal AFE interface; PCB routing must keep the modulator clock traces short and guard the analog inputs from the LCD switching waveforms. The 80-TQFP exposed-pad variant requires solder-pad land pattern on the PCB to keep junction temperature within range at full 48 MHz.
