The Microchip PIC16F1823T-I/ML is an 8-bit PIC core MCU from the PIC® XLP™ 16F family, built for low-power and space-constrained embedded control. It runs at 32 MHz from an internal oscillator, with 3.5 KB of Flash program memory, 128 bytes of RAM, and 256 bytes of EEPROM — enough for small state machines, sensor polling, or LIN-bus node applications in industrial and automotive-adjacent environments. Peripherals include a 10-bit ADC with 8 channels, two PWM modules, and a watchdog timer, plus I²C, SPI, and UART with LIN protocol support for serial communication.
Memory budget — 3.5 KB Flash, 128 B RAM, 256 B EEPROM
With only 3.5 KB of program memory and 128 bytes of RAM, this MCU is sized for single-purpose control loops, not complex RTOS-based firmware. The 256 bytes of EEPROM allow parameter storage across power cycles without external memory — useful for calibration constants or node addresses in a LIN network.
Package — 16-QFN with exposed pad
The 16-VQFN package measures 4x4 mm with an exposed thermal pad.
