The maximum clock frequency for the P80C528FBP is 40 MHz, but it can be overclocked up to 50 MHz with careful consideration of power supply and thermal management.
The P80C528FBP 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 timeout between 16 ms to 2048 ms, and can be reset using the WDTR register.
The P80C528FBP can address up to 64 KB of external memory, but it's recommended to limit it to 32 KB or less to ensure reliable operation and minimize bus contention.
The P80C528FBP has a built-in UART that can be configured using the SCON and SBUF registers. The UART can operate in asynchronous mode with a maximum baud rate of 115200 bps, and supports 5-9 data bits, 1-2 stop bits, and odd/even/none parity.
The power consumption of the P80C528FBP depends on the clock frequency, voltage, and operating mode. At 40 MHz and 5V, the typical power consumption is around 35 mA, but it can be reduced to around 10 mA in idle mode or 1 mA in power-down mode.
