The PIC16LF1526 is a 64-pin Flash-based 8-bit CMOS microcontroller from Microchip Technology featuring the Enhanced Mid-Range core with eXtreme Low-Power (XLP) technology. The ‘LF’ designation indicates a low-voltage variant operating from 1.8V to 3.6V, making it ideal for battery-powered and low-voltage applications. With 49 instructions (up from 35 in the classic Mid-Range) and a 16-level deep hardware stack, it delivers 8 MIPS at 20 MHz. The device offers 14KB (8K x 14 words) of Flash program memory and 768 bytes of RAM. Its standout feature is the extensive peripheral set in a 64-pin package: a 30-channel 10-bit ADC for high-count analog sensing, ten CCP modules for multiple capture/compare/PWM channels, dual MSSP modules providing two independent SPI and I2C interfaces, and dual EUSARTs for dual serial communication. Nine timer modules (6 x 8-bit + 3 x 16-bit) provide flexible timing for the numerous peripherals. With 54 I/O pins, built-in ICD, programmable ULP Brown-Out Reset, and XLP power management, the PIC16LF1526 is well-suited for multi-channel sensor interfaces, LED lighting controllers, serial gateways, and low-power industrial applications requiring high I/O and peripheral count. Available in TQFP-64, QFN-64, and UQFN-64 packages with industrial temperature range (-40°C to +85°C).

The PIC16LF1526 operates on the Enhanced Mid-Range PIC architecture with 49 instructions and a 16-level deep hardware stack, providing 8 MIPS throughput at 20 MHz. XLP (eXtreme Low-Power) technology enables extremely low current consumption in Sleep mode and active operation, making it suitable for battery-powered applications. The low-voltage LF variant operates from 1.8V to 3.6V, directly supporting lithium battery and low-voltage rail systems. The 30-channel 10-bit ADC uses successive approximation register (SAR) architecture with a programmable voltage reference, enabling high-count multi-channel analog sensing applications such as industrial sensor hubs and battery monitoring systems. Ten CCP modules provide 10 independent capture/compare/PWM channels, making the device ideal for multi-channel LED lighting control, motor control, and servo applications where numerous PWM outputs are needed. Dual MSSP modules provide two independent SPI and two independent I2C communication channels, while dual EUSARTs enable dual UART/LIN communication – useful for protocol gateway and multi-interface applications. Nine timer modules (6 x 8-bit, 3 x 16-bit) provide flexible timing resources to support the ten CCP modules and general timing needs. Built-in ICD enables in-circuit debugging without external headers. Power management features include multiple low-power modes, Programmable Ultra Low-Power Brown-Out Reset (ULPBOR), and Extended Watchdog Timer for reliable operation at low voltages.
