The maximum operating temperature range for the LPC1853JET256,551 is -40°C to +105°C.
The clock settings for the LPC1853JET256,551 can be configured using the Clock Control Unit (CCU) registers. The CCU provides a flexible clock generation and distribution system that allows the user to configure the clock frequencies and sources for the various peripherals and domains.
The maximum current consumption of the LPC1853JET256,551 depends on the operating frequency and voltage. According to the datasheet, the maximum current consumption is approximately 350 mA at 100 MHz and 3.3 V.
The LPC1853JET256,551 has a USB 2.0 full-speed device controller that supports both device and host modes. To use the USB interface, you need to configure the USB registers and enable the USB clock. You can then use the USB API provided by NXP to implement USB device or host functionality.
The boot loader on the LPC1853JET256,551 is a small program that runs when the device is powered on or reset. Its purpose is to load the application code from an external memory device, such as a flash memory, into the internal RAM of the microcontroller.
