Microcontroller Features 2.5MB On-Chip Flash Memory

(Product News, 16 Jul 2008)

Renesas Technology Corp.'s SH72544R SuperH family of microcontrollers, designed for control of automotive engine and transmission systems, features high-speed operation of up to 200MHz and a high-speed, large-capacity 2.5MB on-chip flash memory.

In August 2007, Renesas Technology announced the SH72546RFCC software development microcontroller as the industry's first on-chip flash memory microcontroller fabricated using a 90nm process. This device, designed for power train control, operated at 200MHz, and featured a high-speed, large-capacity 3.75MB on-chip flash memory.

The SH72544R is the first mass-production version based on the SH72546RFCC and is fully compatible with the SH72546RFCC's functions, package, and pin assignment. This means that users can directly use the system hardware, programs, and other design assets they have developed using the SH72546RFCC. Application of such assets to this product will be quick and seamless.

The SH72544R operates at 200MHz and can achieve operation at high-temperature environments of ambient temperatures up to 125°C, desirable for automotive applications. In addition, the 2.5MB on-chip flash memory capacity allows it to implement leading-edge high-precision control.

The SH72544R incorporates the high-performance SH-2A CPU core, which achieves 400 MIPS at 200MHz and is optimal for real-time processing. It supports the increasingly large-scale programs required for fine-grained high-level control. In addition, it also includes a 128kB EEPROM function area that allows data to be rewritten during microcontroller operation. Since this obviates the need for the external EEPROMs that were previously used, it can contribute to reduced costs in application systems.
