Renesas Electronics Corporation has announced the new RX660 group of microcontrollers (MCUs) that is a new addition to the RX 32-bit MCU Family and supports operating voltages of up to 5V, offering superior noise tolerance for home appliances and industrial equipment exposed to high electromagnetic interference. The high operating voltages of these new RX660 MCUs eliminate the need for external noise-suppression components that are required for many 3V MCUs.
The company developed the RX660 using its RXv3 core (6.00 CoreMark/MHz) with a maximum operating frequency of 120 MHz, offering high performance and excellent power efficiency. These devices feature large-capacity ROM of up to 1 megabyte (MB) and RAM of up to 128 kilobytes (KB) and are available in many package options (48-pin to 144-pin). In particular, the effective pin count for general-purpose I/O pins is 10% higher than on the earlier RX210, which is also 5V compatible.
Key Features
- 32-bit RXv3 CPU core
- Low-power design and architecture
- On-chip code flash memory
- On-chip data flash memory
- On-chip SRAM
- External address space
- Reset and supply management
