R5F524T8ADFM#11 Product Overview
When selecting a microcontroller for dual-inverter motor control systems, designers typically focus on three things: whether there's a hardware floating-point unit to simplify complex control algorithms, whether the compute performance can drive two motors simultaneously, and whether a 5V single supply can directly interface with industrial drive circuits. The Renesas R5F524T8ADFM#11 from the RX24T series was built for exactly that requirement.
The device features an 80MHz RXv2 32-bit CISC Harvard architecture core with a single-precision Floating-Point Unit (FPU), delivering 153.6 DMIPS to execute sensorless vector control algorithms with native floating-point operations, significantly reducing software development and maintenance time. It integrates 128KB code flash, 16KB SRAM, and 8KB data flash (E2 DataFlash), operating from a 2.7V to 5.5V single supply. Peripherals include a 12-channel 12-bit ADC (in 3 units), 4-channel analog comparator, 4-channel PGA, DTC data transfer controller, independent watchdog timer, LVD and POR reset management, plus 3× SCI/UART, 4× SPI, and 4× I²C interfaces with 48 I/O ports in an LFQFP-64(10×10) package rated for -40℃ to +85℃.
