RX24T and RX24U MCU line-up now addresses hi-temp applications

Renesas Electronics is expanding its RX24T and RX24U Groups of 32-bit microcontrollers (MCUs) to include new high-temperature-tolerant models for motor-control applications that require an expanded operating temperature range.

The RX24T G Version and RX24U G Version are able to support operating temperatures ranging from −40°C to +105°Cs.

In industrial machinery and office equipment, as well as home appliances that handle hot air and heated water, circuit boards are increasingly being mounted in high-temperature locations. That and the shift toward circuit board design with a smaller surface area means that the board’s capacity to disperse heat is limited.

To address this, Renesas is now adding high-temperature-tolerant products to its MCU lineup that can operate in high-temperature spaces and on hot circuit boards. These devices will be able to provide greater flexibility for designers of products that operate in high-temperature environments, enabling the trend toward more compact devices to advance.

Software can be developed using the RX24T and RX24U CPU cards combined with the 24 V Motor Control Evaluation Kit which enables developers to create motor control applications in less time.

The 32-bit RX24T and RX24U features a maximum operating frequency of 80 MHz. It is equipped with peripheral functions for motor control such as timers, A/D converter, and analogue circuits that enable efficient control of two brushless DC motors by a single chip.

With the addition of the G versions, all 32-bit RX MCU family products for motor-control applications now support operating temperature from −40°C to +105°C, extending the scalability of the RX Family and providing system manufacturers a rich and scalable lineup to choose from.

The RX24T G Version and RX24U G Version are available now in mass production. The RX24T covers 11 models with pin counts ranging from 64 to 100 pins and memory sizes from 128 KB to 512 KB. The RX24U covers six models with pin counts ranging from 100 to 144 pins and memory sizes from 256 KB to 512 KB.
