The maximum operating temperature range for the LPC2921FBD100,551 is -40°C to +85°C.
The clock settings for the LPC2921FBD100,551 can be configured using the Clock Generation Unit (CGU) and the PLL. The CGU generates the clock signals for the CPU, peripherals, and external clocks. The PLL is used to generate the CPU clock frequency. The configuration is typically done through the LPC2921's register settings.
The maximum current consumption of the LPC2921FBD100,551 depends on the operating frequency, voltage, and peripherals used. According to the datasheet, the typical current consumption is around 100 mA at 100 MHz, but it can go up to 200 mA or more depending on the specific use case.
The LPC2921FBD100,551 has a built-in Power Management Controller (PMC) that allows for dynamic voltage and frequency scaling, as well as power gating of peripherals. The PMC can be configured to reduce power consumption during idle periods or when certain peripherals are not in use.
The maximum data transfer rate for the USB interface on the LPC2921FBD100,551 is 480 Mbps, which is the maximum speed for a USB 2.0 device.
