The maximum operating frequency of the LPC2129FBD64/01 is 60 MHz, but it can be overclocked to 72 MHz with some limitations.
The clock settings for the LPC2129FBD64/01 can be configured using the PLL (Phase-Locked Loop) and the Clock Generation Unit (CGU). The PLL can be used to generate a clock frequency up to 120 MHz, and the CGU can be used to divide the clock frequency to generate the desired clock speed.
The LPC2129FBD64/01 has 64 KB of flash memory and 16 KB of SRAM (static random-access memory). Additionally, it has 2 KB of EEPROM (electrically erasable programmable read-only memory) for storing data that needs to be retained even when the power is turned off.
The LPC2129FBD64/01 has a USB 2.0 full-speed device controller that can be used to implement USB device functionality. The USB interface can be configured using the USB device controller registers and the USB library provided by NXP Semiconductors.
The power consumption of the LPC2129FBD64/01 depends on the operating frequency, voltage, and mode of operation. In active mode, the typical current consumption is around 20 mA at 3.3 V and 60 MHz. In sleep mode, the typical current consumption is around 10 μA at 3.3 V.
