Microchip Technology, Inc. Microcontrollers PIC18F23K20T-I/ML

The PIC18F23K20T-I/ML is an 8-bit microcontroller from Quarktwin Technology Ltd. featuring a high-performance RISC CPU architecture optimized for C compiler use. It offers up to 8 KB of Flash program memory, 4 KB of SRAM, and 256 bytes of EEPROM. The device operates at a voltage range of 1.8V to 3.6V and supports up to 16 MIPS performance with a 16-bit instruction set and an 8-bit data path. This microcontroller includes a flexible oscillator structure with a factory-calibrated internal oscillator capable of operating at frequencies from 31 kHz to 16 MHz, and it can achieve up to 64 MHz using a phase-locked loop (PLL) without requiring external components. It features a 10-bit analog-to-digital converter (ADC) with 13 external channels and supports various communication protocols, including I2C and SPI. Additional features include a self-programmable capability, programmable high/low voltage detection, a brown-out reset, and an extended watchdog timer. The device is designed for low power consumption, with sleep mode drawing less than 100 nA at 1.8V. It provides up to 35 I/O pins, including high-current sink/source capabilities, and supports multiple interrupt sources. This microcontroller is suitable for applications requiring efficient power management and robust performance.
