Renesas has launched a new high-performance microprocessor for advanced human-machine interface (HMI) systems that are based on a real-time operating system (RTOS).
The new RZ/A3M MPU integrates large DDR3L SDRAM and SRAM memories to facilitate the seamless execution of complex tasks and to render real-time graphics displays. The RZ/A3M drives video and camera images to large LCD panels at a resolution of up to 1280 px x 800 px.
The RZ/A3M features a 64-bit Arm® Cortex®-A55 CPU core operating at a maximum frequency of 1 GHz with 128 kbytes of on-chip SRAM. By integrating 128 Mbytes of high-speed DDR3L DRAM in a single system-in-package, the MPU eliminates the complex task of designing a high-speed signal interface for connecting external DDR memory.
The RZ/A3M supports both external NAND and NOR Flash memory via a quad SPI interface for data and code storage. Paired with a driver, high-capacity NAND Flash offers a cost-effective option for memory expansion. Additionally, the RZ/A3M BGA package has a unique pin layout with two main rows positioned on the outside edge. This layout which simplifies PCB routing and enables a low-cost, dual-layer printed wiring board design, providing substantial cost and time savings. Integrating memory in this way simplifies PCB design by reducing the routing complexity and minimizing layout constraints.
Comprehensive development environment
Renesas offers a comprehensive HMI development environment which includes the Flexible Software Package (FSP), evaluation kits, development tools, and sample software. GUI solutions from partner companies facilitate rapid HMI graphics development.
Part supported: RZ/A3M
Board part number: EK-RZ/A3M
The EK-RZ/A3M evaluation kit enables users to easily evaluate the features of the RZ/A3M microprocessor from Renesas. The kit includes an EK-RZ/A3M board, a 5” 720 px x 1,280 px LCD MIPI graphics expansion board, and USB cables, providing resources for the development of high-definition human machine interfaces (HMIs). The board also supports a camera input through a USB interface.
The kit is supplied with an on-board J-Link debugger. It also has several expansion connectors such as SDIO, PMOD, and Arduino headers for connecting sensors and Wi-Fi® and Bluetooth® Low Energy networking cards, allowing users to add more features without expanding the board footprint.
