NXP Semiconductors has introduced the LPC11U68JBD100, a 32-bit MCU based on the ARM® Cortex®-M0+ core which offers designers an easy means to implement Full- Speed USB and many other connectivity options in low-power, low-cost designs.
The LPC11U68JBD100 includes a USB device controller certified by the USB Implementers Forum, and gives designers access to all the USB driver software, tools and short-cuts they need for simple system development and fast time to market. This includes a royalty-free USB stack library, and extensive sets of example code for popular classes of USB device.
The hardware design aspect of USB implementation is also addressed, since the device features an on-chip PHy, helping users to reduce the system-level bill-of-materials cost and design complexity.
To support more demanding data and buffering requirements, as well as larger application code sizes, the LPC11U68JBD100 offers high Flash memory capacity of 256kbytes and SRAM of 36kbytes. Serial connectivity provision includes five USARTs, two I²C interfaces, two serial peripheral interfaces and up to 80 GPIOs. USART, I2C and DMA drivers are included in the on-chip ROM alongside the USB drivers.
The device also includes a new 12-channel, 12-bit, 2Msamples/s ADC, providing high bandwidth and precise inputs.
