PIC18F8628T-I/PT Présentation
A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, volatile data RAM, and a configurable set of peripheral interfaces. The PIC18 family represents Microchip's 8-bit RISC architecture, positioned in the hierarchy: PIC18 -> 8-bit MCU -> microcontroller -> embedded processor -> semiconductor. The "F" prefix designates Flash program memory, enabling in-circuit reprogramming via ICSP, while the LF variants extend operation to lower supply voltages.
Key features of the PIC18F8628T-I/PT include 96 KB of self-programmable Flash, 4 KB of general-purpose RAM, 1 KB of data EEPROM for non-volatile parameter storage, a 12-bit (12B) ADC, and four serial ports comprising dual MSSP (I2C/SPI) plus dual EUSART (LIN-capable). Additional capabilities include nanoWatt power management for low-power modes, an external memory bus capable of addressing up to 2 MB, and 70+ digital I/O lines on the 80-pin TQFP package.
Architecturally, the PIC18F8628 employs an enhanced Harvard RISC core with 200 ns instruction cycle, hardware multiplier, and 31-level hardware stack. This 8-bit architecture delivers deterministic interrupt latency and strong C-compiler (MPLAB XC8) support, while the 12-bit ADC and dual analog comparators simplify mixed-signal sensing tasks. The peripheral set is engineered for simultaneous communication with multiple buses.
Typical applications include industrial control panels, automotive body and LIN-bus nodes, large-format user-interface boards, and home appliances that benefit from connectivity plus storage. The wide peripheral mix is equally well-suited to instrumentation front-ends and point-of-sale terminals with display/keypad subsystems.
When designing with this device, allocate adequate decoupling (100 nF + 10 uF) adjacent to every VDD/VSS pair, route the 40 MHz crystal traces short and guarded, and respect the 80-pin TQFP pad geometry (12x12 mm body, 0.5 mm pitch) for manufacturability. The ICSP pins (PGECx/PGEDx) must remain accessible for field updates.

Applications typiques
PIC18F8628T-I/PT convient pour 6 applications: Industrial Control Panels, Automotive Body and LIN-Bus Nodes, Large-Format HMI and Display Boards, Home Appliance Controllers, Instrumentation and Data-Acquisition Front-Ends, Point-of-Sale Terminals and Printers.
Industrial Control Panels
The PIC18F8628T-I/PT is well suited for industrial control panels that aggregate multiple sensor inputs and drive HMI displays. Its 12-bit ADC resolves analog signals from pressure transducers, temperature probes, and current shunts with 1.6 mV LSB at 5 V VREF, while the 4 KB RAM buffers GUI screen data and command queues. With 2x MSSP plus 2x LIN-capable EUSART, the MCU concurrently interfaces to SPI displays, I2C EEPROM, a LIN keypad node, and an RS-485 mainboard link - no external bus multiplexer required.
Recommandé
Automotive Body and LIN-Bus Nodes
In automotive body-control modules and LIN sub-nodes, the PIC18F8628T-I/PT's two LIN-capable EUSARTs manage master/slave LIN 1.x/2.x communication without external transceivers beyond the LIN phy. The 70+ I/O lines directly drive window lifters, mirror motors, LED matrix indicators, and switch matrices, while the 96 KB Flash accommodates AUTOSAR-style application layers and bootloader slots. The nanoWatt power-management set supports CAN/LIN wake-up from sleep at <5 uA, critical for quiescent-current budgets under 100 uA.
Recommandé
Large-Format HMI and Display Boards
Graphical HMI boards with TFT-LCD panels and capacitive touch benefit from the PIC18F8628T-I/PT's combination of high pin count, large Flash, and dual MSSP channels. One MSSP drives the SPI TFT controller at up to 10 MHz, the second MSSP polls an I2C touch controller, while the dual EUSARTs handle RS-232 service-port and RS-485 PLC backhaul in parallel. The 1 KB data EEPROM stores non-volatile display calibration and runtime counters, and the 4 KB RAM holds frame buffers for menu graphics without external SRAM.
Recommandé
Home Appliance Controllers
Washing machines, dishwashers, and induction cooktops rely on the PIC18F8628T-I/PT for its mix of connectivity and motor-control-friendly timers. The MSSP channels talk to LED-segment or character-LCD front-panel modules; the EUSARTs communicate with inverter boards, sensor hubs, and Wi-Fi modules; and the 12-bit ADC reads NTC temperature sensors, zero-cross detectors, and current-sensing transformers. The 96 KB Flash is more than enough for state-machine firmware plus a UI library, and nanoWatt idle cuts standby power to meet energy-rating rules.
Recommandé
Instrumentation and Data-Acquisition Front-Ends
Bench-top instruments and modular data-acquisition front-ends leverage the PIC18F8628T-I/PT's 12-bit ADC, large memory, and multiple serial ports for sensor aggregation. The dual EUSARTs route SCPI command traffic to a host PC while passing measurement bursts to a downstream logger; the MSSPs daisy-chain SPI ADCs and DACs for self-calibration loops. The 1 KB EEPROM stores per-channel calibration constants, while the 96 KB Flash fits embedded calibration routines and digital-filter libraries for transducer linearization.
Recommandé
Point-of-Sale Terminals and Printers
POS terminals and receipt printers use the PIC18F8628T-I/PT to manage keypad scanning, customer-facing displays, mag-stripe or NFC readers, and thermal-printer head control. The 70+ I/O lines directly multiplex the keypad matrix, LCD backlight PWM, and thermal-printer stepper motor phases without external logic. One MSSP drives the NFC controller over SPI; one EUSART connects to the LAN-isolation board; and the 4 KB RAM buffers transaction records before forwarding to the secure element via the second MSSP.

Principaux différenciateurs

- 5 V native operation (vs 3.3 V LF variant) (vs PIC18LF8628T-I/PT)
Notes de conception
Estimated: At Vdd = 5 V, 40 MHz active current is approximately 16 mA (typical) per family data; total board-level decoupling must include one 100 nF ceramic per VDD/VSS pin pair plus a bulk 10 uF tantalum near the MCU. Place the 100 nF caps within 3 mm of each supply pin to suppress switching transients from the EUSART and MSSP peripherals. The MCLR pin requires its own 10 kohm pull-up and a 100 nF decoupling cap to ground for stable reset behavior.
The 80-pin TQFP (12x12 mm, 0.5 mm pitch) demands a 4-layer PCB with continuous ground plane beneath the package to provide thermal dissipation and EMI shielding. All VDD/VSS pins must be stitched to inner planes with 0.3 mm vias placed within 1 mm of each pad. Route the 40 MHz crystal traces (OSC1/OSC2) as short, matched-length pairs under 10 mm, and guard them with a ground ring on both sides to prevent radiated-clock injection into adjacent analog inputs.
Do not exceed the absolute maximum Vdd of 7.5 V on any F-series pin; even brief transients from inductive loads can latch-up the device. The ICSP pins (RB6/PGC and RB7/PGD) must remain accessible in production - do not strap them permanently to VDD or GND, as this disables in-field firmware updates. For LIN applications, configure the EUSART baud-rate generator for 16x oversampling at the chosen baud; failure to do so produces framing errors at high bus loads.
Informations de conformité
RoHS and lead-free per Microchip product page. The -I (industrial) temperature grade is not AEC-Q100 qualified; for AEC-Q100 automotive applications, choose the PIC18F8627T-E/PT extended-grade variant.
