The NXP LPC315x combine an 180 MHz ARM926EJ-S CPU core, High-speed USB 2.0
OTG, 192 KB SRAM, NAND flash controller, flexible external bus interface, an integrated
audio codec, Li-ion charger, Real-Time Clock (RTC), and a myriad of serial and parallel
interfaces in a single chip targeted at consumer, industrial, medical, and communication
markets. To optimize system power consumption, the LPC315x have multiple power
domains and a very flexible Clock Generation Unit (CGU) that provides dynamic clock
gating and scaling.
The LPC315x is implemented as multi-chip module with two side-by-side dies, one for
digital fuctions and one for analog functions, which include a Power Supply Unit (PSU),
audio codec, RTC, and Li-ion battery charger.
