The Apollo4 Plus is the latest addition to Ambiq’s portfolio of power efficient processers engineered for battery-powered endpoint devices. An integrated GPU and display controller supports vector graphics, anti-aliasing, four layers of alpha blending, and dithering.
Operating at up to 192 MHz and with 4.75 MB of combined memory, developers can differentiate their products with bigger and richer display user interfaces without sacrificing battery life.
The Apollo4 Plus display kit includes an Apollo4 Plus EVB baseboard and Apollo4 Plus display shield that includes an AMOLED 454x454 display with a MIPI DSI interface. Use I²C for touch capability on the display. The kit also contains a Hex-MSPI interface for fast access to external PSRAM.
