MCUs with LCD controller

6 July 2011 DSP, Micros & Memory

With an integrated LCD controller, up to 96 KB of on-chip SRAM and a 32-bit external memory interface, the LPC178x series of ARM Cortex M3-based MCUs from NXP Semiconductors allows designers to easily add high-quality graphics to their applications. 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 devices 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-colour.

The end of ‘entry-level’: STMicroelectronics’ STM32C5 sets a new baseline for embedded systems
DSP, Micros & Memory
[Sponsored] Instead of incrementally improving legacy Cortex-M0+ architectures, STM32C5 introduces a Cortex-M33-based platform into the entry-level category. This changes not only performance expectations, but also how engineers approach system architecture, consolidation, and long-term scalability.
