LPC11U1x - Cortex-M0 USB Solutions With Smart Card Interface
NXP's LPC11U1x series provides a compelling replacement for 8- and 16-bit USB microcontrollers, delivering robust USB performance at a low price point.
The highly flexible USB architecture is quite simply a better approach to USB. NXP offers the widest range of ARM based USB solutions, as well as easy-to-use software and integrated development platforms that make NXP a one-stop shop for USB.
The LPC11U1x enables maximum USB performance by providing up to 10 configurable physical endpoints with flexible user defined buffer architecture management, faster post-processing of USB data, and robust asynchronous USB operation.
In contrast to typical USB implementations, endpoint buffers in the LPC11U1x do not reside within the USB domain but reside in system SRAM space, giving the CPU direct access to USB packets. Unused endpoint buffer space is not wasted and can be fully utilized by reallocating it as system SRAM.
