PIC18F2510-E/ML - 32KB Flash 8-bit MCU 40MHz QFN-28 | Microchip
MPN： PIC18F2510-E/ML ✓ 啟用中PIC18F2510-E/ML 概覽
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, working RAM, and configurable peripherals on one silicon die, intended for embedded control tasks. Within the broader taxonomy, the PIC18F2510-E/ML sits in the category hierarchy: PIC18F2510 -> PIC18F family -> PIC microcontroller family -> 8-bit microcontroller -> microcontroller -> embedded processor -> semiconductor. The 'PIC18' suffix denotes Microchip's enhanced 8-bit architecture with 16-bit instructions and C-compiler-friendly orthogonal instruction set, while 'F' indicates Flash program memory. The 'E' temperature suffix specifies an extended operating range of -40C to +125C, and 'ML' denotes the QFN-28 plastic package with a thermal pad.
Key features include 25 digital I/O pins, four timer modules (Timer0/Timer1/Timer2/Timer3), a 10-bit ADC with 11 input channels, hardware multiply (8x8 single-cycle), and an internal oscillator block supporting 31 kHz to 8 MHz. nanoWatt technology provides Run, Idle, and Sleep modes with Idle currents down to 5.8 uA typical and Sleep currents down to 0.1 uA typical. The Fail-Safe Clock Monitor allows safe shutdown if the primary clock fails, and the on-board watchdog timer uses a separate RC oscillator for maximum independence from the system clock.
Typical applications include industrial control systems, sensor interfacing boards, motor control loops, low-power battery-powered sensor nodes, and small-form-factor consumer devices requiring 8-bit deterministic processing. The wide operating voltage range of 2.0V to 5.5V allows direct connection to single-cell Li-ion, two-cell alkaline, or regulated 3.3V/5V rails, simplifying power-tree design.
When designing with this device, ensure decoupling capacitors are placed within 3 mm of VDD/VSS pins and that the exposed thermal pad is soldered to a sufficient copper pour to dissipate internal heat. The ICSP/ICD pins must remain accessible for in-circuit debug, and unused I/O pins should be configured as outputs low to minimize current consumption.

PIC18F2510-E/ML 適用於 7 應用s: Industrial Sensor Interface Board, Battery-Powered Wireless Sensor Node, Small Motor Control / BLDC Driver Board, Home Appliance Control Panel, Automotive Body Electronics, Portable Consumer Device Controller, Test and Measurement Front-End.
Industrial Sensor Interface Board
The PIC18F2510-E/ML fits industrial sensor-interface boards because its 25 digital I/O pins and 11-channel 10-bit ADC handle multiple analog transducers and discrete signals simultaneously. The 40 MHz CPU runs at 10 MIPS, providing real-time throughput for linearizing thermocouple, RTD, and 4-20 mA inputs. nanoWatt Sleep at 0.1 uA typical lets the board enter low-power standby between measurement intervals, extending battery life in remote installations. Extended -40C to +125C operation handles factory-floor temperature swings without derating. Place 100 nF ceramic decoupling on each VDD/VSS pair and route the exposed thermal pad to a 1 square inch copper pour to dissipate regulator self-heating.
推薦
Battery-Powered Wireless Sensor Node
The PIC18F2510-E/ML suits battery-powered wireless sensor nodes where its Sleep current of 0.1 uA typical and Idle current of 5.8 uA typical per the manufacturer datasheet dominate total energy budget. Wide 2.0-5.5V supply allows direct connection to single-cell Li-ion or two-cell alkaline packs without boost conversion. The MSSP peripheral drives SPI/I2C sensors and the USART connects to wireless modules (sub-GHz transceivers, BLE modules). Run, Idle, and Sleep mode switching lets firmware spend 99% of duty cycle in Sleep, waking only on a timer interrupt to acquire and transmit sensor data, extending coin-cell battery life to multi-year horizons.
推薦
Small Motor Control / BLDC Driver Board
The PIC18F2510-E/ML is appropriate for small brushed-DC and BLDC motor control because its two CCP modules deliver PWM outputs at up to 40 MHz resolution and its 10-bit ADC samples back-EMF, current, and position feedback. The 8x8 hardware multiplier accelerates PID control math without consuming MIPS. Hardware quadrature decoding via CCP modules simplifies closed-loop position control. With 32 KB Flash it accommodates small field-oriented-control routines plus telemetry. The QFN-28 package keeps board footprint compact, ideal for integration inside motor housings where space is at a premium and the extended -40C to +125C temperature range handles warm motor environments.

The 10-bit ADC monitors temperature, water level, and humidity sensors with adequate resolution for consumer-grade control loops. Flash-based program memory allows last-minute firmware customization in production without mask ROM delays. The 2.0-5.5V operating range and -40C to +125C extended temperature grade handle the warm, sometimes humid environment inside appliance cabinets without reliability compromise.
推薦
Automotive Body Electronics
The PIC18F2510-E/ML serves automotive body-electronics modules such as seat controllers, mirror adjusters, and ambient lighting controllers thanks to its -40C to +125C extended operating range per Microchip ordering nomenclature. The USART and MSSP connect to LIN bus transceivers or proprietary vehicle networks. The 32 KB Flash stores small protocol stacks plus diagnostic handlers. While not AEC-Q100 qualified, the E-temperature grade is commonly used in non-safety automotive subsystems where OEM qualification is satisfied by the module-level ISO 16750 test program rather than the individual silicon grade.
推薦
Portable Consumer Device Controller
The PIC18F2510-E/ML fits portable consumer devices including fitness bands, remote controls, and handheld instruments because its compact QFN-28 footprint minimizes PCB real estate, while the 10 MIPS performance handles user-interface logic and display driving. nanoWatt Sleep at 0.1 uA typical allows months of standby on a coin cell, and the wide 2.0-5.5V supply range accommodates both disposable alkaline and rechargeable Li-ion cells. Hardware interrupt-on-change I/O wakes the device from Sleep on user-button presses without polling, maximizing battery life while preserving responsive user interaction.
推薦
Test and Measurement Front-End
The PIC18F2510-E/ML suits low-cost test and measurement front-ends including handheld multimeters, signal generators, and educational lab instruments because its 10-bit ADC captures sensor inputs and its USART streams measurement data to a host PC. The 8x8 hardware multiply speeds up RMS calculations and FFT preprocessing. QFN-28 package keeps the analog section close to signal-conditioning circuitry, minimizing trace lengths and preserving measurement integrity. Internal oscillator from 31 kHz to 8 MHz eliminates external crystal cost in non-precision applications where the on-chip accuracy is sufficient.

主要差異化特點

- Drop-in QFN-28 footprint with three drop-in temperature-grade variants (對比PIC18F2510-I/ML)

設計說明
The PIC18F2510-E/ML requires proper decoupling for reliable operation: place a 100 nF ceramic capacitor within 3 mm of each VDD pin and a bulk 10 uF tantalum or ceramic at the regulator output. The device supports a wide 2.0-5.5V supply per the manufacturer datasheet, but the Flash programming voltage specification is 4.2V-5.5V; below 4.2V the device may enter brown-out-protected read-only mode unless the BOR is reconfigured via configuration bits. For battery applications, switch between Sleep and Run modes aggressively, since Sleep current of 0.1 uA typical dominates the energy budget in low-duty-cycle deployments.
Solder the exposed thermal pad (EP) of the QFN-28 (ML) package to a copper pour on the top or bottom PCB layer using at least 6 thermal vias to a bottom-layer heat-spreader plane. Place decoupling capacitors as close as physically possible to the VDD/VSS pins, with the VDD trace width sized for the application's peak current. Route the ICSP/ICD pins (RB6/PGC, RB7/PGD) directly to a programming header without series resistors in the signal path to ensure reliable in-circuit debug. Keep the MCLR line pulled up to VDD with a 10 kOhm resistor and a 100 nF capacitor to ground for proper reset behavior.
When migrating from PIC18F2510 to PIC18F25K20 or PIC18F2515, verify the configuration bits are re-programmed because the newer devices default to different oscillator and watchdog settings. Always check the maximum Flash endurance spec (typically 10K erase/write cycles) when implementing EEPROM emulation in Flash. Do not exceed the absolute maximum rating of 5.5V on VDD or apply voltage to any pin before VDD is powered up, as this can trigger latch-up. Configure unused I/O pins as outputs driving low rather than inputs to minimize Sleep current and prevent floating-node oscillation.
Estimated: at maximum 40 MHz CPU clock with all peripherals active and 25 I/O pins switching, the PIC18F2510-E/ML internal power dissipation is approximately 250-400 mW depending on output loading. The QFN-28 package thermal resistance (theta_JA) is approximately 31-40 C/W when the exposed pad is properly soldered to a 1 square inch copper pour, giving a junction temperature rise of 12-16 C above ambient. For the extended -40C to +125C operating range, ensure ambient plus self-heating does not push the junction above the 150C absolute maximum; use additional copper pours or airflow if needed.
