September 26, 2011 -- NXP Semiconductors today introduced the LPC11D00 and LPC12D00 series of microcontrollers — the first ARM Cortex-M0 microcontrollers with integrated segment LCD drivers, enabling high contrast and brightness in a single chip.
Featuring the NXP PCF8576D LCD driver, the LPC11D00 and LPC12D00 are capable of driving any static or multiplexed LCDs containing up to 4 backplanes and 40 segments, and can be easily cascaded with multiple segment LCD drivers to accommodate up to 2,560 segments for larger display applications. With the LPC11D00 and LPC12D00, NXP can now lower overall system cost up to 15% while providing seamless LCD integration into a wide range of applications including industrial automation, white goods, lighting, home appliances, and portable medical devices. NXP is showcasing the new display microcontrollers at ESC Boston.
"Our Cortex-M0 microcontrollers have become popular as a straightforward replacement for 8- and 16-bit MCUs in white goods and industrial applications. Now we are offering a simple Cortex-M0 solution for system designers who want to be able to drive high-quality, high-contrast segment LCD displays without having to use two chips, or get locked in to legacy MCU architectures," said Jan Jaap Bezemer, Director of Marketing, Microcontroller Product Line, NXP Semiconductors. "The LPC11D and LPC12D series offer a cost-effective entry-level option in our Cortex-M LCD portfolio, which includes Cortex-M3-based graphical LCD controllers capable of driving TFT and STN displays."
In contrast to typical segment LCD driver solutions today, the NXP PCF8576D LCD driver supports a wide LCD supply range from 2.5V to 6.5V, making the LPC11D00 and LPC12D00 an ideal choice for interfacing with both low-threshold and high-threshold LCDs. The integrated PCF8576D increases system reliability and quality, and reduces electrical interconnect and compatibility issues, while incorporating key features such as on-chip display RAM and versatile blinking modes. In addition to blinking the whole display, the LPC11D00 and LPC12D00 also support alternate messages to be displayed at a configurable blink frequency on an arbitrary selection of LCD elements. Display data sent from microcontroller can be stored in the 40x4-bit on-chip display RAM which supports a direct mapping to the LCD elements on the display. Furthermore, these features can be maintained while the microcontroller is in low-power mode, making the LPC11D00 and LPC12D00 a competitive solution for low-power 8/16-bit applications that require low-cost segment LCD integration.
The LPC11D00 supports up to 32kBytes of Flash, 8kBytes of SRAM and offers a rich peripheral set, including 2 SSPs, I2C (FM+), UART, 4 system timers and a 8-channel high-precision 10-bit ADC. As an extension of the energy-efficient LPC1100L family, the LPC11D00 also features unique API-driven power profiles providing users with ready-to-use power-management templates allowing designers to do run-time optimization of performance, efficiency and active power consumption with simple API calls.
The LPC12D00 extends the feature set of the LPC11D00 with up to 128kBytes of Flash and analog peripherals such as dual analog comparators with 32 levels of voltage reference, edge and level detection, and output feedback loop. As the newest addition to the LPC1200 Industrial Control Series, the LPC12D00 is a highly reliable solution for safety-critical industrial automation and white goods applications. The LPC1200 family is rated as high immunity, based on the Electrical Fast Transient (EFT) test conducted by Langer EMV-Technik GmbH per IEC61697-1 recommendations and is IEC 60730 Class B-certified.
