Delivering robust USB performance at a low price point, the low-cost LPC11U Cortex-M0 USB devices from NXP Semiconductors are compelling replacements for 8/16-bit USB microcontrollers. 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.
Connectivity options on the LPC11U00 series include two Synchronous Serial Port (SSP) interfaces, I²C with Fast-mode Plus feature for 10x higher bus-drive capability, a Universal Synchronous-Asynchronous Receiver/Transmitter (USART) and a Smart Card interface. The Smart Card interface (ISO7816-3) provides a plug-and-play interface for Smart Cards, making the LPC11U00 a good fit for e-commerce applications.
As an extension of NXP’s proven LPC1100 family, the LPC11U00 series delivers up to 32 kB Flash, 6 kB SRAM, a variety of serial interfaces, four system timers with PWM functionality, an 8-channel, 10-bit ADC, and up to 40 GPIOs. In addition to several standard package offerings, the LPC11U00 series is offered in a miniature 4.5 x 4.5 mm TFBGA48 package, making it especially suited for small form-factor mobile and consumer applications.
