The 10-channel 12-bit ADC gives you enough analog front-end for current sensing on a three-phase motor without external muxing. ## 40 MHz RX core — timing margin for sensorless FOC At 40 MHz the RX core can execute a single-cycle multiply-accumulate, which keeps the current-loop update rate under 10 µs for a typical sensorless field-oriented control algorithm. That leaves headroom for the speed loop and commutation logic without pushing the core to its ceiling. If your code footprint fits inside 64 KB and the data buffers stay within 12 KB, this part avoids the cost jump to the next density tier. The 48-LQFP package (7x7 mm body) is a common footprint that rework techs can hand-solder with a fine-tip iron if needed, no hot-air station required.","metaTitle":"R5F523T3AGFL#30 Renesas RX23T 32-bit MCU, 40 MHz","metaDescription":"R5F523T3AGFL#30 Renesas RX23T 32-bit MCU: 40 MHz RX core, 64 KB Flash, 12 KB RAM, 48-LQFP, -40 to 105°C.
