PIC16F15375T-I/PT - 14KB Flash 8-bit MCU | Microchip
The Microchip Technology PIC16F15375T-I/PT is an 8-bit PIC microcontroller from the PIC16F153xx family, delivering 14KB (8K x 14) of Flash program memory and 1KB of RAM in a 44-pin TQFP (10x10 mm) package. It operates at up to 32 MHz and supports 2.3V to 5.5V supply, integrating intelligent analog, Core Independent Peripherals (CIPs), and eXtreme Low-Power (XLP) technology for battery-friendly designs.
An 8-bit microcontroller (MCU) is a single-chip computer that combines a CPU, RAM, non-volatile program memory, and peripherals on one die. The "8-bit" refers to the width of its data path and ALU; 8-bit PIC MCUs use a modified Harvard RISC architecture optimized for deterministic interrupt response, low power, and ease of use. PIC16F1xxx devices sit in the mid-range PIC family, balancing cost, code density (14-bit instruction word), and rich on-chip peripherals for embedded control tasks. They are commonly used as the main system controller in IoT nodes, sensor hubs, and consumer appliances, or as co-processors for housekeeping and user-interface tasks.
Key features of the PIC16F15375 include 14KB Flash, 1KB SRAM, up to 36 digital I/O pins, a 10-bit ADC, multiple 8/10-bit DACs, four PWM outputs with Complementary Waveform Generator (CWG), comparators, two EUSART, SPI, and I2C. eXtreme Low-Power features such as Idle and Sleep modes, peripheral module disable, and nanoWatt XLP technology make it well-suited to battery-powered products. The 32 MHz internal oscillator removes the need for an external crystal in many designs.
The device uses the enhanced mid-range PIC16 core with a 14-bit instruction set, hardware multiply assist, and a vectored interrupt controller. Internal data EEPROM emulation through Flash, a configurable logic cell (CLC), and signal measurement timers (SMT) provide Core Independent Peripherals that offload the CPU. Intelligent analog peripherals allow closed-loop control without an external ADC/DAC chain, reducing BOM cost on sensor and motor-control boards.
Typical applications include low-power IoT sensor nodes, home automation controllers, battery-powered handheld instruments, LED lighting controls, motor-control front ends, and human-machine interface (HMI) panels. The combination of XLP, 5.5V tolerance, and rich analog peripherals makes it especially attractive for industrial sensor conditioning and small appliances.
When designing, ensure VDD decoupling uses a 100 nF ceramic capacitor placed within 5 mm of the IC. Use the ICSP header for production programming; for low-power designs, enable the watchdog timer and use Sleep with peripheral interrupts to achieve microamp standby currents. Verify that any unused I/O pins are configured as outputs low to minimize current leakage on the TQFP-44 package.
