NXP expands industrial control series to support energy-efficient controls and appliances
February 22, 2011 // Paul Buckley
NXP Semiconductors N.V. has unveiled its LPC1200 Industrial Control Series featuring the ARM Cortex-M0 processor which extends NXPís 32-bit ARM microcontroller continuum and targets a wide range of industrial applications in the areas of factory and home automation, such as white goods, motor control, power conversion and power supplies.
The new device also expands NXP’s Cortex-M0 microcontroller offering with a wide range of Flash memory sizes. LPC1200 customers can now choose the exact Flash memory size they need, ranging from 32 KB to 128 KB in increments of 8 KB.
The LPC1200 product platform is specifically designed with flexibility and customization in mind, making it particularly suitable for a wide variety of energy-efficient system and power management requirements. For example, in advanced washing machines, the LPC1200 can control the motor systems, handle the user interface, monitor system power consumption, and manage off-board communications in a simple, integrated and energy-efficient solution. Its high current GPIO can directly control TRIACs without the need for external transistors, further reducing footprint and costs.
Designed for smart appliances and white goods In tomorrow’s energy-efficient smart appliance designs, the CPU will not only have to manage the user interface and control, but will also increasingly be required to drive multiple motor systems, as well as continuously measure current and voltage to calculate active power with high accuracy. The LPC1200 series meets these demanding system requirements with its high score of over 45 in CoreMark CPU performance benchmark testing, equivalent to 1.51/MHz.
For high volume applications, the LPC1200 platform can provide rapid delivery of application-specific solutions (ASSP) for a wide range of industrial control requirements, through flexible interconnections between the interrupt controller, DMA sub system, on-chip peripherals and GPIO. By recognizing external and internal events and carrying out pre-defined tasks without CPU intervention, the CPU load is dramatically reduced, allowing the CPU to remain in power down longer.
Maximizing flexibility, efficiency and robustness The NXP LPC1200 offers over 50 Flash and SRAM memory combinations, giving designers maximum flexibility to optimize the features and product cost within the same footprint. In addition, the small 512 Byte erase sector of the Flash memory brings multiple design benefits, such as finer EEPROM emulation, boot-load supports from any serial interface, and ease of in-field programming with reduced on-chip RAM buffer requirements.
Taking advantage of the ARM Cortex-M0 v6-M 16-bit Thumb instruction set, the LPC1200 has up to 50 percent higher code density compared to common 8/16-bit microcontrollers performing typical tasks. The Cortex-M0 efficiency also helps the LPC1200 achieve lower average power for similar applications. NXP’s SRAM architecture allows the LPC1200 to minimize power by automatically setting each of the 2KB low-power blocks into its lowest possible power mode.
Designed for high reliability and robustness, the LPC1200 is rated as high immunity, based on the Electrical Fast Transient (EFT) test conducted by Langer EMV-Technik GmbH per IEC61697-1 recommendations. Electrostatic Discharge (ESD) protection is rated at 8 kV.
The LPC1200 comes with a set of peripherals that are specifically suited for appliances and industrial design:
- A Windowed Watchdog Timer with an independent internal oscillator source, designed to comply with IEC 60730 Class B safety requirements for white goods
- A Programmable Digital Filter on all GPIO pins allowing better control of signal integrity for industrial applications
- I2C with Fast-mode Plus feature with 10x higher bus-drive capability compared to typical I2C I/O drives, allowing for twice as many devices on the same bus, as well as longer transmission distances
- Optimized ROM-based divide library for Cortex-M0 offering several times the arithmetic performance of software-based libraries, as well as a highly deterministic cycle time combined with reduced Flash code size
- Dual analog comparators with 32 levels of voltage reference, edge and level detection and output feedback loop supporting multiple states, such as monostable, astable or simple set/reset
The LPC1200 Industrial Control series is available now in six initial Flash sizes including 32, 48, 64, 80, 96 and 128 KB in both 48LQFP and 64LQFP packages. Devices in the same footprint share exactly the same peripheral sets and are fully pin-compatible. The integrated segment display driver option will become available in LQFP100 package in Q2.
All NXP Cortex-M microcontrollers are upwardly binary compatible and offer all the advantages of a single development toolchain. Users can easily migrate their designs between Cortex-M0 and Cortex-M3 with minimal effort. The easy-to-use LPCXpresso IDE for the LPC1200 series is priced under US $30.
NXP will showcase the LPC1200 at Embedded World in Nuremberg, Germany, March 1-3, 2011 (Booth 12-218), as part of a Smart Appliance demonstration.

Internet of Things (IoT) manufacturer Ciseco has launched the Raspberry Pi ‘Wireless Inventors Kit’ (RasWIK), featuring 88 pieces to provide everything a Pi owner needs to follow a series of step-by-step projects or to create their own wireless devices, without the need for configuration or even writing code.
RasWIK has been designed to be highly accessible, demystifying the dark art of wireless and enabling anyone with basic computing skills to begin building wireless devices with a Raspberry Pi. You can create anything from a simple traffic light, to a battery monitor, or even a temperature gauge that sends data to the Xively IoT cloud so billions can access the data.This month, Ciseco is giving away twelve Raspberry Pi Wireless Inventors kits, worth £49.99 each for EETimes Europe's readers to win.
And the winners are...
In our previous reader offer, Farsens was giving away five kits for EEtimes Europe readers to evaluate its FenixVortex, Kineo and X1 wireless, battery free sensor tags.
Lucky winners include Mr A. Neil from the UK, Mr. E. Delvaux from Belgium, Mr Lengal from the Czech Republic, Mr H. Bijlsma from the Netherlands, and Mr G. Pfaff from Germany. All should be receiving their packages soon. Lets wish them some interesting findings with their projects.
