The Right Choice for HMI Designs

RZ/A1 Embedded ARM® Microprocessors

The RZ Family of ARM-based High-Performance MPUs

Renesas RZ/A1 series microprocessors (MPUs) offer an innovative architecture based on the ARM Cortex®-A9 processor and up to an industry-leading 10MB of on-chip memory. RZ/A1 MPUs can execute code at 1000 DMIPS from the abundant on-chip memory or in-place from inexpensive QSPI memory, while using on-chip memory for graphics buffering up to WXGA (1280x800) resolution. The 128-bit wide internal memory bus with x4 parallel access enables higherthroughput memory access as compared to systems with external DDR memory. The RZ/A1 series offers enormous advantages in terms of BOM cost, performance, power consumption, and system design time, making it the right choice for HMI (Human Machine Interface) and other system-on-chip applications.

Create Superior HMI Designs with Fewer Components

On-chip functions provided by RZ/A1 MPUs reduce BOM cost, save board space and minimize integration tasks. Typical applications like the one shown below take advantage of a rich portfolio of intellectual property from Renesas and can utilize a range of built-in peripherals, including: CMOS camera interface, JPEG Codec Unit, 12-bit ADC, and OpenVG 2D graphics engine, among others.
