The maximum clock frequency for the P87C528EBPN is 33 MHz, but it can be overclocked up to 40 MHz with careful consideration of power supply and thermal management.
The UART serial communication on the P87C528EBPN can be configured using the SFRs (Special Function Registers) such as SCON, SBUF, and PCON. The baud rate, data bits, parity, and stop bits can be set using these registers.
The power consumption of the P87C528EBPN depends on the operating frequency, voltage, and mode. In active mode, the typical power consumption is around 20-30 mA at 5V and 33 MHz. In idle mode, it can be as low as 10-20 mA.
The P87C528EBPN has a built-in watchdog timer that can be enabled and configured using the WDTR and WDTC registers. The watchdog timer can be set to reset the microcontroller if it does not receive a reset pulse within a specified time period.
Yes, the P87C528EBPN can operate with a 3.3V power supply, but the maximum clock frequency may need to be reduced to ensure reliable operation. The datasheet recommends a maximum clock frequency of 20 MHz at 3.3V.
