NXP Cortex-M0 micros get more memory and package options
NXP has announced the LPC11U30 series of very low-power USB microcontrollers based on the ARM Cortex-M0 processor. The LPC11U30 extends memory options for the LPC11U00 family with up to 4 KB of EEPROM, 12 KB of SRAM and 128 KB of NXP’s embedded flash with 256 bytes of erase sector.
With extra-low active power consumption as low as 110 uA/MHz, the LPC11U30 microcontrollers are ideal for USB 2.0 applications requiring large memory sizes for local storage such as gaming mice and keyboards, glucose meters, and remote-controlled toys.
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. With multiple USB drivers integrated into ROM, the LPC11U30 microcontroller maximises flash memory use and provides fully tested APIs that enable easy USB integration, which can be further enhanced by using nxpUSBlib, NXP’s fully featured open source USB library.
