Renesas

 

Renesas Electronics has extended its Synergy™ S5 MCU series with the introduction of the entry-level S5D3 MCU group. The four new S5D3 MCUs join the mid-range S5D5 and high-end S5D9 MCU groups in the S5 series.

Based on a 120MHz Arm® Cortex®-M4 core, the S5D3 MCUs provide features, including advanced security capabilities, which simplify the design of cost-sensitive, low-power IoT end points.

In addition, the Renesas Synergy Software Package (SSP) supports the S5D3 MCUs through the provision of drivers, application frameworks and a real-time operating system. Embedded system designers can use either the Renesas e² studio or the IAR Embedded Workbench® integrated development environment to build and customize their designs.

Based on a 40nm fabrication process, the S5D3 MCUs integrate a secure cryptographic engine, the SCE7, with key protection which safeguards boot code and IoT end point device communication with a root of trust. This capability eliminates the need for external security functions. The SCE7 features encryption hardware accelerators for RSA, DSA, AES, ECC and SHA cryptography, alongside a true random number generator, to enable secure system connections to the cloud.

The S5D3 MCUs feature 512kbytes of Flash memory and a large 256kbyte SRAM. This 2:1 ratio of embedded Flash to SRAM supports intensive utilization of communication stacks for robust IoT connectivity. The 8kbytes of data Flash enable more read/write cycles than competing MCUs.
