.@Renesas_Europe says 240MHz RX71M #MCUs are shipping. The devices have up to 4Mbyte of flash.

The RX71M group features 112 variants, pin counts ranging from 100 to 177 pins, flash capacities from 2 to 4Mbyte and 512kbyte of RAM. The RX700 series operates at up to 240MHz, double the previous maximum operating frequency. This is said to equate to 4.4CoreMarks/MHz at 240MHz, which Renesas says is amongst the best performing flash MCUs. The RXv2 core is said to deliver 1.3 times the performance of the earlier RXv1 core, whilst maintaining code compatibility. Manufactured on a 40nm process and capable of operating at 120 MHz, and the advanced fetch unit (AFU) incorporating exclusive cache-based memory control technology, achieve performance equivalent to no-wait access when operating at 240 MHz. Even if a cache miss occurs, the performance penalty is equivalent to only one cycle, so excellent real-time performance can be achieved even when using only the flash memory. T...
