Cypress – MCU with integrated graphics engine supports sophisticated display functions


The FM4 S6E2D series of ARM® Cortex®-M4 based microcontrollers from Cypress Semiconductor features a dedicated hardware graphics engine which enables designers to implement an attractive display in a cost-effective, single-chip solution.

The S6E2D series devices are ideal for embedded applications which have a user interface based on a TFT LCD. They include a graphics display controller and 512kbytes of video RAM. A variant with 2Mbytes of integrated video Flash is also available. The devices also provide multiple interfaces to the extensive storage capacity required to support image and video display applications, including High-Speed Quad-SPI Flash, HyperBus and external video RAM interfaces.

Together, the graphics engine and video RAM on the S6E2D MCUs enable the implementation of sophisticated graphics features, including complex image overlap, alpha blending, rotation, mirroring, scaling and image movement. Running in the graphics engine, these functions entail a minimal CPU overhead.

Like other members of the FM4 family, the S6E2D series of MCUs includes generous provision of analogue and digital capabilities. On the analogue side, they feature two 12-bit, 1Msample/s ADCs with a 24-channel multiplexer input.

In the digital domain, the MCUs offer a multi-function timer, six programmable pulse generators, eight general-purpose base timers, a USB host and function interface, and a CAN-FD interface, as well as eight channels of multi-function serial interfaces configurable as SPI, UART, I2C or LIN.
