C8051F581-AQ Product Details

C8051F581-AQ Overview


The embedded microprocessor ships overseas conveniently packed in QFP. There is MICROCONTROLLER MICROCONTROLLER in the uPs, uCs, or peripheral ICs categories. A total of 48 terminations have been recorded. Turn on the cpu microprocessor and let it run with a 2.1V voltage supply. There are 8 bits in its architecture. 48 pin functions are described in the datasheets. With a maximum supply current of 2.75V, it has a maximum power consumption. As a Microcontrollers, this cpu microprocessor is typical. Injecting pins into the embedded microprocessor body results in 48 pins. In this CPU microprocessor, the clock frequency is 0 Hz. It is specified in the datasheet that this micro processor requires 2/5V power supplies. 33mA voltage higher than 33mA can be supplied to the CPU. CPU programs transfer data via 40 I/Os. Over -40°C is the recommended operating environment. As a 8051 embedded microprocessor, it belongs to the class of devices.
