SINGAPORE: NXP Semiconductors N.V. announced its LPC11U00 series – a low-cost ARM® Cortex-M0 based microcontroller featuring a new, highly flexible USB architecture, as well as a smart card interface. Equipped with a highly configurable Full Speed USB 2.0 device controller, the LPC11U00 brings unparalleled design flexibility and reliable USB connectivity for consumer electronics and mobile devices.
"The LPC11U00 series provides a compelling replacement for 8- and 16-bit USB microcontrollers, delivering robust USB performance at a sub-dollar price point. The highly flexible USB architecture we’re introducing in the LPC11U00 is quite simply a better approach to USB,” said Geoff Lees, vice president and general manager, microcontroller product line, NXP Semiconductors. “NXP now 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 LPC11U00 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 LPC11U00 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. This feature is especially suited for protocol converters such as UART-to-USB and SPI-to-USB bridges where data needs to be quickly transferred between serial interfaces.
With the LPC11U00 USB architecture, each non-control endpoint can be configured for either bulk, interrupt or isochronous, and can be double-buffered with maximum packet sizes of 1023 bytes. Further, the flexible clocking architecture supported by a dedicated USB PLL enables asynchronous USB operation, with the CPU and USB operating independently at maximum speeds.
As an extension of NXP's proven LPC1100 family, the LPC11U00 series delivers up to 32KB Flash, 6KB SRAM, a variety of serial interfaces, a smart card interface, 4 system timers with PWM functionality, 8 channel 10-bit ADC and up to 40 GPIOs. The LPC11U00 series is offered in a miniature 4.5 x 4.5 mm TFGBGA48 package especially suited for small form factor mobile and consumer applications, in addition to several standard package offerings.
