PIC16F15356T-I/SO - 8-Bit XLP MCU, 32MHz, 28KB Flash, 28-SOIC | Microchip
The Microchip Technology PIC16F15356T-I/SO is an 8-bit PIC microcontroller from the PIC® XLP™ 16F family, integrating 28KB (16K × 14) of Flash program memory, 2KB of data RAM, and a wide peripheral set into a 28-pin SOIC package. It operates at up to 32MHz from a 2.3V to 5.5V supply, with 25 digital I/O pins, four 10-bit PWMs, two EUSART, SPI, and I2C interfaces, plus analog peripherals that include a 10-bit ADC, a 5-bit DAC, comparators, and four Configurable Logic Cells (CLC). The "XLP" eXtreme Low-Power designation and Core Independent Peripherals (CIPs) make this device a strong fit for battery-powered and always-on applications.
An 8-bit PIC microcontroller is a microcontroller built around an 8-bit data path Harvard architecture, where program and data memories use separate buses to speed up fetch and execute cycles. PIC16F1 series parts add peripheral flexibility through CLCs, numerically controlled oscillators, and signal routing that let designers implement logic glue and waveform synthesis without external components. As a category, microcontrollers sit within the broader hierarchy of embedded controllers, microprocessors, and semiconductor ICs used to give products programmable intelligence.
Key features of this part include the CIPs block (CLC, CWG, NCO, DSM) for offloading timing-sensitive tasks from the CPU, four 10-bit PWMs for LED, motor, or power control, the 5-bit DAC plus comparator pair for analog signal conditioning, and the device's broad peripheral set that reduces external component count. With XLP sleep currents in the nanoampere range and a wide operating voltage window, the part is engineered for energy-harvesting and battery-backed designs.
The PIC16F15356T-I/SO architecture combines a 16-level hardware stack, an interrupt controller with context save, and the enhanced mid-range instruction set, providing re-entrant code compatibility with prior PIC16F1 generation tools while exposing new peripherals. The 28-SOIC package supports standard surface-mount assembly and gives 25 I/O for keypad, display, or sensor interface tasks.
Typical applications include IoT sensor nodes, home appliances with HMI displays, low-power wireless remote controls, battery management subsystems, LED lighting controllers, and industrial sensor interface boards. The combination of CLCs, CWG, and PWMs makes this MCU especially well suited to driving MOSFETs in low-end motor and lighting circuits.
When designing with this device, budget decoupling with a 100nF ceramic cap adjacent to each VDD pin, place a 10µF bulk capacitor at the regulator output, and reserve an ICSPCLK/ICSPDAT header for in-circuit programming. The internal 32MHz oscillator typically eliminates the need for an external crystal in cost-sensitive designs.
