NXP Semiconductors PCF84C21AT is an 8-bit microcontroller from the PCF84C21 series. This CMOS device operates at a maximum clock frequency of 16MHz and features 2KB of MROM program memory with an 8-bit width. It offers 20 general-purpose I/O lines and one serial I/O, supporting an I2C serial bus interface. The microcontroller includes one timer and one external interrupt. It operates within a supply voltage range of 5.0V to 5.5V and has a maximum supply current of 6mA. Designed for surface mounting, it is housed in a 28-terminal, rectangular, small outline plastic package (PDSO28). This component is suitable for applications in consumer electronics and industrial control systems, with an operating temperature range of -40°C to +85°C.
