Product Overview
The PIC16LF1526-I is a 64-pin, 8-bit Flash-based CMOS microcontroller from Microchip Technology featuring the Enhanced Mid-Range core and eXtreme Low-Power (XLP) technology. With 49 instructions and a 16-level deep hardware stack, this low-voltage MCU offers 14KB (8K x 14 words) of Flash program memory and 768 bytes of RAM (no EEPROM). Operating at up to 20 MHz across a low voltage range of 1.8V to 3.6V (LF variant), it integrates an impressive 30-channel 10-bit ADC, ten CCP modules, two MSSP (SPI/I2C) modules, two EUSARTs, and nine timers. With its large pin count, extensive I/O capabilities, and dual communication interfaces, the PIC16LF1526 is ideal for applications requiring many analog inputs, multiple PWM outputs, and dual serial communication channels in a low-power, low-voltage design.
