Renesas RX260 and RX261 64 MHz RXv3 MCUs target power-efficient touch applications
The Renesas RX260 and RX261 two new 64 MHz microcontrollers part of the high-performance, high-efficiency RX product family with integrated capacitive touch-sensing and high power efficiency in both active and standby modes. The microcontrollers are based on the RXv3 core with a performance score of 355 CoreMark @ 64MHz, which is β2.5 times higher than competing 64 MHz class MCUs.β The chips are also power-efficient, with a consumption rate of 69ΞΌA/MHz during active operation and 1ΞΌA only in standby mode. According to Renesas, the chips are up to 25% more efficient in active mode and 87% more efficient in standby mode than other 64 MHz class MCUs. Another competing factor is the onboard 8KB of data flash, eliminating the need for external EEPROM. The RX260 and RX261 Group MCUs support noise- and water-resistant capacitive touch via Renesasβ third-generation capacitive touch IP (CTSU2SL). They also integrate an βautomatic judgment functionβ that [...]
