The maximum operating temperature range for the LPC662AIM is -40°C to 105°C, but it can be extended to 125°C with some limitations on the clock frequency and voltage supply.
The clock source for the LPC662AIM can be configured using the Clock Generation Unit (CGU) registers. The CGU allows selection of the clock source, clock frequency, and clock divider settings. Refer to the LPC662AIM user manual for detailed instructions.
The maximum current consumption of the LPC662AIM depends on the operating frequency, voltage supply, and peripheral usage. According to the datasheet, the maximum current consumption is around 130 mA at 100 MHz and 3.3V supply voltage.
The ADC on the LPC662AIM is a 12-bit successive approximation ADC. To use the ADC, configure the ADC clock, select the ADC channel, and start the ADC conversion using the ADC registers. The ADC result can be read from the ADC result register.
Yes, the LPC662AIM can be used with an external crystal oscillator. The external crystal oscillator can be connected to the XTAL1 and XTAL2 pins, and the clock source can be selected using the CGU registers.
