The maximum operating temperature range for the LPC4370FET100 is -40°C to +105°C, but it can be extended to -40°C to +125°C with some limitations on the clock frequency and voltage supply.
The internal oscillators on the LPC4370FET100 can be configured using the SYSCON registers. The IRC (Internal RC oscillator) can be enabled by setting the IRCEN bit in the SYSCON_IRCCTRL register, and the PLL (Phase-Locked Loop) can be enabled by setting the PLLEN bit in the SYSCON_PLLCTRL register.
The maximum current consumption of the LPC4370FET100 depends on the operating frequency, voltage supply, and peripherals used. According to the datasheet, the maximum current consumption is around 350 mA at 3.3V and 204 MHz, but this can be reduced to around 20 mA in low-power modes.
The USB interface on the LPC4370FET100 can be used by configuring the USB registers and using the USB library provided by NXP. The USB interface supports both device and host modes, and can be used for communication, data transfer, and charging.
The maximum clock frequency for the LPC4370FET100 is 204 MHz, but it can be overclocked to 240 MHz with some limitations on the voltage supply and temperature range.
