PIC16F526-I/SL 8-Bit Flash Microcontroller
The PIC16F526-I/SL is a cost-effective, high-performance 8-bit RISC microcontroller from Microchip Technology, belonging to the PIC16F5xx baseline family. Housed in a compact 14-pin SOIC package, it operates efficiently over a wide voltage range of 2.0V to 5.5V, supporting up to 20 MHz clock frequency for fast execution. It features 1.5 KB of self-programmable Flash program memory, 67 bytes of RAM data memory, and an on-chip 4/8 MHz internal oscillator, eliminating the need for external crystal components and simplifying design. Equipped with essential analog and digital peripherals, it integrates a 3-channel 8-bit ADC, two analog comparators, and one 8-bit timer/counter, making it highly versatile for low-to-medium complexity embedded control tasks. Built-in power-on reset (POR), watchdog timer (WDT), and in-circuit serial programming (ICSP) ensure reliable operation and easy firmware updates.
