PIC16F15225-I/MG
PIC16F15225-I/MG - 8-bit MCU, 14KB Flash, 32MHz, 16-QFN | Microchip
The Microchip Technology PIC16F15225-I/MG is an 8-bit PIC microcontroller built on the Enhanced Mid-Range core running at up to 32MHz, with 14KB (8K x 14 words) of self-read/write Flash program memory and 1KB of RAM, packaged in a compact 16-pin QFN (3x3 mm, MG package). It belongs to the PIC16F152xx family, which combines Core Independent Peripherals (CIPs) such as 2x CCP and 2x PWM with intelligent analog (10-bit ADC) and standard serial interfaces (EUSART, SPI, I2C via MSSP) for sensor and motor-driven embedded designs.
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory, data RAM, and peripheral interfaces. In the broader hierarchy, an MCU is a subset of microprocessors specialized for embedded control. The 8-bit class targets cost-sensitive, deterministic, low-power applications such as appliance controls, sensor hubs, IoT endpoints, and battery-powered devices where 32-bit performance is unnecessary. The PIC16F15225's eXtreme Low Power (XLP) Sleep mode and Peripheral Pin Select (PPS) routing fit this exact use-case profile.
Key differentiating features of this PIC16F15225 variant include 14KB Flash with self read/write capability, 1KB RAM, 10-bit ADC, 2 CCP (Capture/Compare/PWM) channels, 2 dedicated PWM channels, EUSART, MSSP (SPI/I2C), and XLP Sleep mode. According to the Microchip datasheet, the device delivers 49 instructions with 16 stack levels and supports in-circuit serial programming for production-line firmware updates.
At the architecture level, the PIC16F15225 uses a Harvard RISC core with a 14-bit instruction word, 16 levels of hardware stack, and a flexible oscillator block supporting internal 32MHz HFINTOSC without external crystals. Peripheral Pin Select remaps digital peripheral I/O to multiple pins, simplifying PCB routing and enabling smaller 16-QFN layouts.
Typical applications include home-appliance control boards, low-power IoT sensor nodes, LED lighting drivers with PWM dimming, battery chargers, fan controllers, and small consumer electronics. The compact 3x3 mm QFN footprint suits space-constrained designs such as wearable bands and portable medical accessories.
Designers should note that PIC16F15225 is the 16-pin, 14KB-Flash variant in the family. Larger-memory and higher-pin-count siblings (e.g., PIC16F15244, PIC16F15245) share the same peripheral set but require different packages. Programming is supported through MPLAB X IDE and XC8 compiler, and the MPLAB Code Configurator generates driver code for ADC, PWM, EUSART, MSSP, and PPS in seconds.
