Supporting sophisticated graphics and large display sizes (up to 10 inches with XGA resolution, 1024 × 768), the hybrid MCU SiP combines the MPU and memory into a single package. It features an Arm926EJ-S processor and 512 Mbit DDR2 SDRAM.
Display interface options include MIPI Display Serial Interface (DSI), Low Voltage Differential Signaling (LVDS) and RGB data in parallel.
Possible automotive applications, for example, include digital cockpit clusters, smart clusters for two- and three-wheelers, HVAC control and EV chargers.
SAM9X75D5M features
Connectivity options cover CAN FD, USB and Gigabit Ethernet (GbE). It also supports the Time-Sensitive Networking (TSN) protocol and comes with integrated 2D graphics and audio capabilities.
And Microchip support for HMI systems includes its maXTouch technology, which provides power management and reliable touch sensing. For example, in harsh environments or with water on the LCD screen
The SAM9X75D5M supports both RTOS (Real-Time Operating Systems) and Linux environments.
SiP
“Microchip’s SAM9X75D5M product redefines the standard for automotive-grade solutions, combining a high-performance processor with memory in a single package and bringing benefits of a SiP to the automotive market,” said Rod Drake, corporate vice president of Microchip Technology’s MPU business unit.
“One of the advantages of a SiP is that it provides significantly more RAM buffer space than a traditional MCU implementation and on a much more compact PCB than can be done with discrete memory—giving designers options to fit complex designs into a small space.”
Dev tools
In terms of development tool support, the SAM9X75D5M is supported by the MPLAB X Integrated Development Environment (IDE) and MPLAB Harmony Software Framework. This is for development for RTOSs including FreeRTOS and Eclipse ThreadX.
You can also use Microchip Graphics Suite (MGS) or other third-party graphics software tools such as Crank, LVGL, Altia and Embedded Wizard to develop the graphics.
The SAM9X75 Curiosity LAN Kit (EV31H43A) is available for evaluating SAM9X75 SiP devices.
Finally, for pricing and availability, the SAM9X75D5M is available now for $9.12 each in 5,000 unit quantities. Larger 1 Gbit and 2 Gbit memory devices for automotive are available for sampling now, adds Microchip.
