Renesas Electronics Corporation, a supplier of advanced semiconductor solutions, announced a new addition to its popular RL78 microcontroller (MCU) Family that includes 8- and 16-bit devices for power-sensitive applications.
The RL78/G24 features the highest performance among all the devices in the RL78 family, boosting its performance with an application-specific Flexible Application Accelerator (FAA) and a fast CPU that can achieve an operating frequency of 48MHz.
The device’s enhanced peripheral functions, including analog and timer capabilities, are ideal for motor control, power supply control, and lighting control.
In particular, by using the FAA, the device can distribute tasks such as inverter control, encryption, sensing, and arithmetic operations efficiently and independently of the CPU, thus substantially boosting processing speed.
“We are thrilled to introduce the top-of-the-line product from the popular RL78 Family, which holds the world’s largest share in the 16-bit MCU market today,” said Toshihiko Seki, VP of MCU Device Solution Division at Renesas. “With an extensive range of features and specifications, the RL78 Family empowers our customers to achieve the highest performance, while minimizing costs.”
Features
- CPU operating at 48 MHz (max.) and FAA operating independently from the CPU
- 12-bit A/D converter capable of simultaneous sampling of three channels with a maximum conversion speed of 1 µs (microsecond)
- High-speed comparator with a latency of 50 ns (nanosecond) typ.
- Equipped with DALI-2 function for lighting communication standard
- High temperature support up to 125° C
- Compact package offering, with the smallest 3 x 3 mm package option
The RL78/G24 offers a standby function to reduce power consumption. Customers can choose from two modes, HALT mode, which cuts power consumption by 60% compared to normal operation mode, and STOP mode, which reduces power consumption by 99% compared to HALT mode. These power-saving modes allow the device to use less power overall.
“Traditionally, processing was done only by the CPU core and a significant burden was placed on the CPU. Tuning to achieve a balance between high-speed processing and CPU load took a considerable amount of time,” added Osamu Ogura, software development manager, Industrial System Development Division of TESSERA TECHNOLOGY, a Renesas eco-system partner. “With the FAA capability that comes with the RL78/G24, we were able to divide the communication processing for the CPU and power control as with the FAA. This allowed us to shorten the development time overall.”
