The recommended operating voltage range for P87LPC764FD is 2.4 V to 3.6 V, with a typical voltage of 3.3 V.
The clock source for P87LPC764FD can be configured using the CLKCFG register. You can choose between an internal RC oscillator, an external clock source, or a crystal oscillator.
The maximum clock frequency supported by P87LPC764FD is 12 MHz.
The UART interface on P87LPC764FD can be used by configuring the UART registers (UARTn_TXD, UARTn_RXD, UARTn_CTS, and UARTn_RTS) and enabling the UART clock. You can also use the UART FIFOs to improve data transfer efficiency.
Yes, the P87LPC764FD has several low-power modes, including Idle mode, Sleep mode, and Deep-sleep mode, which can be used to reduce power consumption in low-power applications.
