NXP Semiconductors N.V. has rolled out the LPC1100LV, an ARM Cortex-M0 microcontroller with dual supply voltage of 1.65V to 1.95V VDD and 1.65V to 3.6V VIO.

The LPC1100LV series offers 50 MIPS performance in a tiny 2 x 2mm chip-scale package (WLCSP) with over three times power reduction compared to similar 3.3V VDD devices, NXP said. The LPC1100LV platform is specifically designed for battery-powered end applications ranging from mobile phones, tablets, Ultrabooks and mobile accessories to active cable, cameras, and portable medical electronics.

Using NXP's latest proprietary embedded flash with 256B erase sector and low leakage current, the LPC1100LV can handle linear current consumption at low clock frequency while reducing system power. For example, in a mobile system such as a smartphone, most system components are expected to remain mostly in sleep mode with very low current consumption. When a device is needed, fast wake-up and peak performance must be reached in a short amount of time. The LPC1100LV meets this demand with a 5us wake-up time.

LPC1100LV

The LPC1100LV claims to be the world's first ARM Cortex-M0 microcontroller with dual supply voltage of 1.65V to 1.95V VDD and 1.65V to 3.6V VIO.

According to NXP, the LPC1100LV devices deliver 50 MIPS of performance compared to the 1 to 5 MIPS performance typical of 8/16bit MCUs. This high performance allows LPC1100LV to complete demanding tasks faster and to remain in active mode for a shorter period of time, further reducing the average current consumed by the device. Given the same task, LPC1100LV's unique 1.65V-1.95V VDD low-voltage input offers more than three times power reduction compared to competitor Cortex-M0 devices using 3.3V VDD input, and more than ten times compared to typical 8/16bit MCUs. Subsystems that can take special advantage of the LPC1100LV's MIPS performance include system security and authentication (including handling AES-256 encryption), system interface and controls (such as keypads and touchscreens), system peripheral controls (for audio and lighting), and for running software stacks (such as Bluetooth Low Energy radio).

Also available in a 5 x 5mm HVQFN package and offering 1.8V VDD and 3.3V VIO dual voltage inputs for CPU and I/O, NXP says this option offers a unique level-shifting capability between SSP/SPI (3.3V) and I2C (1.8V). NXP is also offering customized combinations of SRAM, Flash and package for high-volume customers.

Samples are available today for lead customers.
