EINDHOVEN, THE NETHERLANDS and SAN JOSE, CA — (Marketwire) — 03/27/12 — NXP Semiconductors N.V. (NASDAQ: NXPI) today announced the featuring a fully interconnected and flexible analog subsystem, based on the ARM® Cortex-M0 processor. Combining 50-MHz CPU performance with advanced analog features including Undervoltage Lockout (UVLO) in a 2.5 x 2.5-mm WLCSP package, the LPC11A00 is an ideal replacement for 8/16-bit microcontrollers in a variety of power management applications, which present significant challenges in terms of overall system performance, space constraints, and harsh environments. Fully integrated with an on-chip temperature sensor and up to 4 KB of EEPROM, the LPC11A00 microcontroller is well-suited for uninterrupted power supplies (UPS), power inverters, intelligent battery chargers, power factor correction, sensors, lighting, and power-conversion applications.
“The introduction of the LPC11A00 series shows our continued commitment to push the limits for flexible analog integration,” said Jan Jaap Bezemer, director of marketing, microcontroller business line, NXP Semiconductors. “NXP offers the most comprehensive Cortex-M0 microcontroller portfolio in the industry, supporting analog, USB, CAN, segment LCD, and dual-supply solutions.”
The integrated UVLO feature eliminates the need for external components and allows the microcontroller to remain in a safe system state whenever the supply voltage level is below the minimum valid operating level of 2.4V. This feature supports various kinds of power supply ramps including cold power-up, power droop, and power-down ramps, making the LPC11A00 extremely useful in power control and monitoring applications.
“Vicor-s VI Chips have set standards for power density, efficiency and speed,” said Dave Brush, director of strategic sourcing, Vicor. “The LPC11A00 allowed us to easily migrate from our previous 8-bit solution while adding more performance, lowering power consumption and reducing board space. Its UVLO functionality enabled us to provide the robust start-up that our customers demand, making the LPC11A00 the ideal microcontroller for our applications.”
The analog subsystem in the LPC11A00 microcontroller includes UVLO protection against power-supply drops below 2.4V; on-chip comparator with programmable voltage reference; 10-bit ADC with input multiplexing among 8 pins; 10-bit DAC with flexible conversion triggering; an integrated temperature sensor; and a highly accurate 0.9 voltage reference which can be used for internal ADC calibration. By providing seamless integration of the various analog blocks, the LPC11A00 allows system designers to off-load critical tasks from the CPU.
The interconnected subsystem offers flexible operation allowing the comparator to trigger ADC and DAC operations while taking timestamps from a 32-bit or a 16-bit timer. Conversely, these analog operations can also be triggered by the timers. For efficient system monitoring, the comparator and the timers can be further configured to make time measurements of fluctuating analog signals.
Ideal for small form factor power applications, the 20-pin WLCSP 2.5 x 2.5-mm package enables debugging/programming via the I2C-bus — a unique feature which minimizes the number of pins for system integration while simplifying board layout. On-chip ROM-based routines for the I2C interface enable seamless integration via an easy-to-use API-driven interface. The LPC11A00 WLCSP20 pin-out offers two memory configurations (16 KB and 32 KB) with up to 4 KB EEPROM, while supporting all peripherals including USART, SSP and 18 GPIOs.

NXP is showcasing the LPC11A00 this week at ESC Silicon Valley 2012, a DESIGN West Summit, in booth 1308. The LPC11A00 series is currently sampling to lead customers and will be available for volume production in early Q2 2012. The NXP LPC11A00 will be one of the Cortex-M0 microcontrollers covered under NXP-s new Product Longevity Program for microcontrollers, which was also announced today.
In addition to the WLCSP, the LPC11A00 will also be available in the 33-pin HVQFN and 48-pin LQFP packages. Recommended distribution unit pricing for LPC11A11FHN33/001 in 10,000 piece quantities for the HVQFN33 package is at US $1.28 with 8 KB Flash, 2 KB SRAM and 512 B EEPROM.
