NXP offers M0 with LCD driver
“Our Cortex-M0 microcontrollers have been tremendously 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.”
NXP’s PCF8576D LCD driver supports a wide LCD supply range from 2.5 V to 6.5 V, 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 40 x 4-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.
The LPC11D00 supports up to 32 KB of Flash, 8 KB of SRAM and offers 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 API-driven power profiles providing users with ready-to-use power management templates allowing designers to do runtime optimization of performance, efficiency and active power consumption with simple API calls.
The LPC12D00 extends the feature set of the LPC11D00 with up to 128 KB of Flash and highly innovative 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 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.
