TMS470PLF221RFPQ1 is TI's ARM7-based MCU, which is specially developed for the development of automotive dashboards. It has 6 stepper motor drivers, which can subdivide the control of six instrument motors at the same time. HET, which can generate very precise timing, cooperate with DMA and multi-buffer serial SPI, can complete the external function design, and takes up very little resources. In addition, the chip has built-in CAN and LIN controller, which is very suitable for car. Development of dashboards. Lerda has developed a high-end automotive dashboard solution based on the TMS470PLF221RFPQ1 with TFT LCD.
