The HMI market continues to drive progress in higher person expertise and elevated automation with the enlargement of HMI functions. This ends in a powerful demand for improved performance and efficiency in display-based functions, akin to real-time plotting, clean animation, and USB digicam picture seize, in reasonably priced methods. Microprocessors (MPUs) with high-speed, large-capacity built-in reminiscence that can be utilized like microcontrollers (MCUs) are gaining consideration out there. Renesas’ RZ/A3M MPU with a built-in 128MB DDR3L SDRAM and a suitable package deal for a two-layer PCB design is the perfect resolution for realizing clean animation and high-quality HMI at an inexpensive system value.
Excessive-Efficiency HMI and Actual-Time Graphics
Integrating high-speed, large-capacity reminiscence straight into the MPU package deal affords a number of benefits, together with mitigating considerations about high-speed sign noise on the PCB and simplifying PCB design for the customers. The big-capacity reminiscence wanted for high-performance HMIs is externally linked to the MPU within the standard manner. Moreover, PCBs outfitted with DDR reminiscence and high-speed sign interfaces require multi-layer PCB designs to account for sign noise, making it difficult to scale back PCB prices. Additionally, the widespread capability of on-chip SRAM is often between 1MB and 10MB, which is simply too small for high-performance HMIs that want to incorporate an inexpensive variety of duties within the close to future. To beat these points, Renesas launched an industry-leading RZ/A3M MPU with a big built-in 128MB DDR3L reminiscence to help high-performance HMI and real-time graphics efficiency to reinforce higher and quicker person experiences. Most significantly, the board doesn’t require a high-speed sign interface and helps two-layer PCB design to scale back board noise and simplify system improvement for customers.

Designing Excessive-Efficiency PCBs at a Cheap System Value
The variety of PCB layers and the convenience of design considerably influence the price of system implementation and upkeep in person functions. As proven in Determine 2, utilizing a large pin pitch of 0.8mm permits for the structure of sign traces and placement of VIAs between the balls. Moreover, putting the balls dealing with the primary indicators within the outer rows of the 244-pin 17mm x 17mm LFBGA package deal and positioning the GND and energy pins as internal balls permits for environment friendly routing of the required sign traces for the system (Determine 3). The RZ/A3M MPU is designed to construct cost-effective methods with two-layer PCBs via its progressive packaging and pin assignments.

Person-Pleasant Interface Enabling Easy GUI Show
The high-resolution graphic LCD controller built-in into the RZ/A3M helps each parallel RGB and 4-lane MIPI-DSI interfaces, accommodating shows as much as 1280×800. Moreover, the 2D graphics engine, high-speed 16-bit 1.6Gbps DDR3L reminiscence, and 1GHz Arm Cortex-A55 CPU allow high-performance GUI shows, together with clean animations and real-time plotting that improve the potential of automation in HMI functions. Connecting a USB digicam to the USB 2.0 interface permits clean seize of digicam photos, making it simple to examine within an equipment, for instance, the doneness of the meals within the oven or the situation within the fridge.
The EK-RZ/A3M is an analysis package for the RZ/A3M. It contains an LCD panel with a MIPI-DSI interface. With this package, customers can instantly begin analysis. Renesas additionally has a number of graphics ecosystem companions – LVGL, SquareLine Studio, Envox, Crank, RTOSX – who ship GUI options using the EK-RZ/A3M to additional speed up your improvement cycle.
