The RX24T Group features a 32-bit microcontroller ideally suited for dual inverter control

with a built-in Floating-Point Unit (FPU) that enables it to easily program complex inverter

control

algorithms.

This

helps

to

greatly

reduce

the

man- hours

required

for

software

development, overflow management and overall maintenance.

RX24T microcontrollers are designed to ensure the highest noise immunity and operate in

a

voltage

range from 2.7 V to 5.5 V, providing the highest reliability for any equipment

using inverter. Finally, the RX24T offers good compatibility with the RX62T Group in terms

of pin arrangement and software support.
