PIC18F25Q10-I/SP - 32KB Flash 8-bit MCU 28-Pin SPDIP | Microchip
The Microchip Technology PIC18F25Q10-I/SP is a 32 KB Flash, 8-bit PIC microcontroller built around the enhanced mid-range PIC18 core, supplied in a 28-pin SPDIP (SP) through-hole package with industrial -40C to +85C temperature rating. The Q10 family integrates Core Independent Peripherals (CIPs), Configurable Logic Cells (CLCs), and intelligent analog blocks, allowing designers to offload timing-critical logic from the CPU and shorten firmware development cycles. Operating voltage spans 1.8V to 5.5V with on-chip voltage regulation, and 5V operation is emphasized for noise immunity in harsh industrial environments.
An 8-bit microcontroller (MCU) is a small, self-contained computer-on-a-chip that integrates a CPU, Flash program memory, SRAM data memory, EEPROM, and peripherals on a single die. Within the broader taxonomy it sits under microcontroller -> embedded controller -> integrated circuit -> semiconductor. The PIC18F25Q10 belongs to Microchip's PIC18-Q10 family, which is optimized for robust real-time control and sensor-node applications that benefit from deterministic hardware-driven behavior.
Headline specifications include 64 MHz maximum CPU clock (16 MIPS at 4x PLL), 32 KB self-programmable Flash, 2 KB SRAM, 256 B EEPROM, two 10-bit ADC modules offering up to 35 channels, two comparators, two DACs, two PWMs with 16-bit resolution, CLCs, and communication peripherals comprising UART/SPI/I2C. The 5V operating range improves noise margin over 3.3V-only MCUs in motor-control and industrial sensor interfaces.
The architecture leverages an 8-bit Harvard RISC pipeline with hardware multiply and 49 instruction types, supported by the MPLAB X IDE, XC8 compiler, and Microchip's MPLAB Code Configurator (MCC) for peripheral setup. Intelligent analog lets the ADC, comparator, and DAC perform hardware-triggered conversions without CPU intervention, reducing latency and jitter.
Typical applications include IoT sensor nodes, motor control (BLDC, stepper), HVAC actuator control, LED lighting drivers, low-end touch HMI, battery-powered metering, and industrial automation. For automotive body electronics, the matching PIC18F25Q10-E/SP and AEC-Q100 Q10 variants provide qualified alternatives.
When designing with this MCU, prioritize using CLCs for hardware state machines and the DMA-like Peripheral Pin Select to free the core for application code. Decouple VDD/VSS with 100 nF ceramic caps placed within 3 mm of the package pins, and provide bulk capacitance on AVDD if ADC accuracy is critical.
This page synthesizes distributor pricing, drop-in SPDIP alternatives, and practical design notes not found in the bare manufacturer datasheet, enabling a faster PCB redesign or BOM swap than reading the 769-page datasheet end to end.
