Overview
Description
The RX230 Group of devices leverages an optimal combination of a 32-bit RXv2 CPU core with improved DSP/FPU and low-power consumption technology to realize extreme power efficiency. High-performance digital filtering, floating-point operations, and other processing can be performed even in environments with low current supply capacity. The RX230 Group is optimized for the general market requiring 5V power supply support, external bus, high DSP/FPU operational performance at low power consumption or high sensitivity, high level of noise tolerance capacitive touch sensor function for HMI applications.

RX230, RX231 without Temp Range in product option
Our product design requires operation temperature range higher than 100 degree, but there is no "Temp. Range" option for Rx230, Rx231 in the "Product options", this makes it hard to choose parts. I check the datasheet for RX230, Rx231, the first page has "operation temperature range" (-40 to +85; -40 ...
