Low-power USB MCUs

22 August 2012 DSP, Micros & Memory

NXP Semiconductors announced the LPC11U30 series of low-power USB microcontrollers based on the ARM®Cortex-M0 processor. They feature up to 4 KB of EEPROM, 12 KB of SRAM and 128 KB of embedded Flash with 256 Bytes of erase sector. With active power consumption as low as 110 μA/MHz, the MCUs are ideal for USB 2.0 applications requiring large memory sizes for local storage. The LPC11U30 supports the latest USB 2.0 specification with Link Power Management (LPM) mode, which allows a device to enter a suspended state when not in use. It also offers on-chip power profiles optimised for specific power levels, including a low-current mode ideal for battery-powered applications that only connect to USB for occasional charging or data download.
