Rochester Electronics 8-bit 8BIT Embedded Microcontroller MCU P89LPC922FDH

The P89LPC922FDH is an 8-bit microcontroller from Quarktwin Technology Ltd. featuring a two-clock 80C51 core, which allows for high performance with instruction execution times of 111 ns to 222 ns at a maximum frequency of 18 MHz. It includes 8 kB of Flash memory and 256 bytes of RAM, making it suitable for applications requiring moderate memory capacity. The microcontroller supports various integrated features such as two 16-bit counter/timers, a real-time clock, and two analog comparators. It also offers an enhanced UART with advanced interrupt capabilities and a 400 kHz I¬=C-bus communication port. The device operates within a voltage range of 2.4 V to 3.6 V and is 5V tolerant on I/O pins, allowing for flexibility in interfacing with other components. It comes in a compact 20-pin TSSOP package, which is advantageous for space-constrained designs. Additional features include in-application programming, a watchdog timer, and multiple power-saving modes, making it a versatile choice for low-power applications. The P89LPC922FDH is designed for high-integration and cost-effective solutions, suitable for a wide range of embedded system projects.
