NXP Semiconductors has announced its LPC1200 Industrial Control Series, targeting applications in factory and home automation such as white goods, motor control, power conversion and power supplies.

The LPC1200 expands NXP’s Cortex-M0 microcontroller offering with a wide range of Flash memory sizes.

LPC1200 customers are able to choose the exact Flash memory size they need, ranging from 32KB to 128KB in increments of 8KB.

The LPC1200 product platform is designed with flexibility and customisation 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.

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 more than 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 recognising 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.

The NXP LPC1200 offers more than 50 Flash and SRAM memory combinations, giving designers the flexibility to optimise the features and product cost within the same footprint.

In addition, the small 512B 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 per cent 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.

Further, NXP’s unique SRAM architecture allows the LPC1200 to minimise 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 per IEC61697-1 recommendations.

Electrostatic Discharge (ESD) protection is rated at 8kV.

The LPC1200 extends NXP’s Cortex-M0 microcontrollers portfolio with up to 55 GPIOs, multiple timers/serial channels, and new onboard peripherals including RTC, DMA, CRC and one per cent internal oscillator, which provides the required accuracy for Baud rate generation.

Upcoming LPC1200 derivatives will also include additional features, such as an integrated 40×4 segment display driver.

The LPC1200 Industrial Control series is available now in six initial Flash sizes including 32, 48, 64, 80, 96 and 128KB 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.
