Overview
Description
RX26T Group microcontrollers are 5V-compatible products which provide dual-motor control using Field Oriented Control (FOC) and Power Factor Correction (PFC) control on a single chip. The RXv3 core, a 3rd generation RX CPU core operating at 120 MHz, flash memory capable of 120 MHz read operations, and a trigonometric function unit (TFUv2) provide a higher level of compute performance. The timer functions support 120MHz PWM (3-phase complementary x 2 channels + single-phase complementary x 2 channels), and analog function is provided by 12-bit A/D converter x 3 units (2 units with a 3-channel simultaneous sample & hold circuit). The lineup includes a HOCO with guaranteed oscillation accuracy of ±1.0% (-20°C≤Ta), data flash memory, a single-ended PGA, comparator and other components in a compact QFN package attributes to reduction in the number of components and space saving. In addition, it offers CAN-FD for high-speed inter-device communication and I3C Basic for high-speed communication with sensors which enable faster data transfers. The flash memory has a dual bank configuration, and the BGO/SWAP function to enable rewriting of the firmware without system stoppage. Trusted Secure IP-Lite with its integrated key management function and cryptographic engine reduces the risk of information leaks from the system.
