Description
The RX261 group is a 32-bit microcontroller that delivers outstanding power efficiency, advanced touch functions, and robust security. It is suitable for a wide range of applications including consumer electronics, industrial automation, building automation, and battery-powered products.
The RXv3 core delivers a high performance of 355CoreMark at 64MHz operation. Active current is 69μA/MHz, and standby current is 1μA. Power consumption can be minimized during intermittent operation by using a snooze mode that allows peripheral functions to operate during standby.
The third-generation capacitive touch sensing unit (CTSU2SL) is included as an HMI function. The CTSU2SL supports multi-frequency scanning to reduce false detection due to external noise, active shield to suppress the effects of water on the electrodes, the automatic judgment function to detect touch events without CPU activation, and the MEC function to reduce touch measurement time and current consumption for multiple electrodes.
The RSIP-E11A is also equipped with a full range of security features, with built-in AES, ECC, and SHA engines. Management functions are provided to prevent unauthorized use of the cryptographic engine and leakage of keys. In addition, it has the area protection function that allows the user to set a non-rewritable area on the code flash memory. This is ideal for storing secure boot programs, etc.
