Renesas RZ/T1

RZ/T1 - Real-Time Processor Solution for up to 600 MHz

The RZ/T1 Group is a factory automation solution with built-in industrial network functionality for use in many industrial applications such as AC servo drives, motion controllers, inverter control and general industrial equipment that require high speed, responsiveness, and excellent real-time performance. Traditional solutions such as high-frequency microprocessors (MPUs) with cache memory are unsuited for real-time control because of the unpredictability characteristics of cache memory. And, while micro controllers (MCUs) with on-chip flash memory are likewise marketed for real-time control, the increasing performance requirements are driving them to hit their performance ceiling. In addition, deterministic, open standard networks such as EtherCAT®, EtherNet/IP™, and PROFINET are becoming mainstream in all types of industrial equipment. Supporting such standards typically requires the use of a separate ASIC with dedicated communication functionality, which leads to increased system cost and circuit board footprint.

The RZ/T1 Group of devices are built around the ARM® Cortex®-R4F core operating at up to 600 Megahertz (MHz) and are configured with two regions of tightly coupled memory (TCM, Note 1), which is linked directly to the CPU core, removing the need for cache memory. TCMs support critical routines, such as interrupt handling routines or real-time tasks, ensuring the highest level of responsiveness with no cache latency.
