ARM Cortex M3 based MCU with built in LCD controller

NXP Semiconductors N.V. has announced the volume availability of its LPC1788 microcontroller ARM Cortex-M3-based MCU with an integrated LCD controller. It consists of up to 96 KB of on-chip SRAM and a 32-bit external memory interface. The LPC178x series supports applications such as graphics display panels, industrial automation, point-of-sale, and medical diagnostic applications.

"Recent advances in human-machine interface are starting to transform LCD displays in industrial, retail and medical environments. The LPC178x Cortex-M3 microcontrollers deliver an integrated LCD controller at a breakthrough price point, providing a low-cost solution for embedded system designers who want to add attractive TFT displays with animation," said Jan Jaap Bezemer, director of marketing, microcontroller business line, NXP Semiconductors.

The LCD interface includes its own DMA controller to allow it to operate independently of the CPU and other system functions. A built-in FIFO acts as a buffer for display data, providing flexibility for system timing, while hardware cursor support can further reduce the amount of CPU time needed to operate the display. In addition, the NXP LPC178x microcontrollers support Super-Twisted Nematic (STN) and Thin-Film Transistor (TFT) graphic display panels up to 1024 x 768 pixels, from monochrome up to 24-bit true-color.

The 120-MHz LPC178x MCUs have up to 512 KB Flash, 96 KB SRAM and 4 KB EEPROM memory on-chip. The 32-bit external memory controller supports SDRAM, NOR and SRAM devices with four chip selects.

Additional peripherals available on the LPC178x and LPC177x series include a Host/Device USB controller, a 10/100T Ethernet controller, Anti-Tampering Event Recorder, eight-channel General-Purpose DMA (GPDMA) controller, 12-bit ADCs, 10-bit DAC, motor control PWM and Quadrature Encoder Interface, five UARTs, three I2C, I2S, three SSP/SPI, Smart Card interface, four timers, windowed watchdog timer, an ultra-low power RTC, and up to 165 general purpose I/O pins

Availability: Now.
Pricing: $3 to $7 for 10K units.
