Renesas introduces new 32-bit microcontrollers

Integrates connectivity functions and system control capabilities on a single chip

By CBR Staff Writer

Renesas Electronics, a provider of semiconductor offerings, has introduced the six new 32-bit microcontrollers (MCUs), the SH726A and SH726B.

The microcontrollers are the new members in the SH7260 Series of MCUs with large-capacity on-chip SRAM, which are designed to lower the system cost of products while achieving a smaller mounting area, the company said.

In addition to existing features such as internal SRAM, support for serial flash memory and a proven Media SDK implementing audio codecs (MP3, AAC, WMA), the new products are equipped with a new bus controller enabled with connection of quad-SPI flash ROM provides smaller package with lower pin count reducing system cost.

The maximum CPU operating frequency of the MCUs is 216 megahertz (MHz, 1.5 times that of the existing SH7266 MCUs) which improves system expandability through high-speed operation.

The SH726B MCUs also implement two USB (full-speed) channels on-chip, providing support for connection of multiple USB devices of various types, including portable audio players and USB storage.

The MCUs also include software development kits (SDKs) incorporating drivers and middleware for digital audio applications to further reduce the time and resources required for system development, the company said.
