Overview
Description
The RX72M Group microcontrollers are high-performance products operating at 240MHz with the RX's third-generation CPU core,"RXv3 core". Double-precision floating-point processing instructions can significantly improve processing power. It incorporates an EtherCAT® slave controller and realizes a system configuration that requires a dedicated controller on a single chip, contributing to a reduction in the number of parts and space saving.
Features
- RXv3 Core 240MHz operation (5.82 CoreMark/MHz), double-precision FPU
- 2.7V to 3.6V operation
- Operating Temperature: -40 °C to 85 °C/-40 °C to 105 °C
- Large-capacity memory: Code flash up to 4MB, SRAM 1MB
- Dual Bank Function
- Line up max. 224-pin LFBGA package product
- Built-in EtherCAT slave controller
- Supports small TFT LCD display (to WVGA)
- Trusted Secure IP (Optional)
