NXP introduces dual power supply voltage ARM Cortex-M0 microcontroller

NXP Semiconductors announced the introduction of the LPC1100LV series, the world's first ARM® Cortex™-M0 microcontroller that supports dual supply voltages from 1.65V to 1.95V VDD and 1.65V to 3.6V VIO. The LPC1100LV series is available in a 2mm x 2mm micro package with performance up to 50 MIPS and power consumption more than three times lower than comparable 3.3V VDD devices. The LPC1100LV platform is specifically designed for battery-powered end-use applications, including mobile phones, tablets, Ultrabooks™, and mobile accessories for active cables, cameras, and portable medical electronics.

Jan Jaap Bezemer, Director of Marketing, NXP Semiconductor MicroController Business Unit, said: "Generally, high-performance dual-supply voltage products are not currently available in a single micro package. "The LPC1100LV series uniquely combines these critical requirements for battery-powered applications in the same device, allowing customers to create unprecedented low-power solutions."

Designed for low power consumption and fast wake up

Thanks to NXP's new 256-byte erase sector and low leakage current embedded proprietary flash memory, the LPC1100LV handles linear current consumption at low clock frequencies, while also reducing system power consumption. For example, in mobile systems such as smartphones, most system components need to be in extremely low-power sleep mode most of the time. When the device needs to be used, it must wake up quickly and reach peak performance in a very short time. The LPC1100LV has a wake-up time of 5us, which fully meets this requirement.

Perform more demanding tasks more efficiently

NXP's LPC1100LV device can achieve performance of 50 MIPS, compared to the typical performance of an 8/16-bit MCU of only 1 to 5 MIPS. Its outstanding performance allows the LPC1100LV to complete extremely demanding tasks faster and reduce the time spent in active mode, further reducing the average power consumption of the device. For the same task, the LPC1100LV uses more than three times less power than competing Cortex-M0 devices with 3.3V VDD inputs, and more than ten times less than typical 8/16-bit MCUS, thanks to its unique 1.65V-1.95V VDD low-voltage input. Subsystems that can take full advantage of the LPC1100LV's MIPS performance include: system security and verification (including handling AES-256 encryption), system interfaces and controls (such as keyboards and touch screens), system peripheral controls (audio and lighting), and operation of the software stack (such as Bluetooth low power radio).

Small size and unique level switching function

The LPC1100LV comes in an NXP 2-mm x 2-mm Microchip-scale package (WLCSP) - the smallest 32-bit MCU in the world. Available in a 5-mm x 5-mm HVQFN package option, the device offers a 1.8V VDD and 3.3V VIO dual voltage input for the CPU and I/O, with a unique level conversion capability between SSP/SPI (3.3V) and I2C (1.8V). NXP also offers custom combinations of SRAM, flash and packaging for large customers.
