    Products Detail

    ST72F321J9TCTR Overview


    Packaged in a 44-LQFP format, this MCU is available in a compact size. There are 32 I/Os on the Microcontroller. It is important to note that the Microcontroller has a Surface Mount mounting type. 8-Bit core is the basis for this Microcontroller. This program has a type of memory called FLASH for this MCU's program memory. Temperatures in this range are operated by this Microcontroller. The ST7 series includes this electrical component. There is 60KB 60K x 8 bytes of program memory in MCU, which corresponds to the size of the program. With a ST7 Core processor, MCU is equipped with the latest technology available. 60kB memory size belongs to the Chip part. Alternatives can be found by looking at the base part number ST72F32. In the case of 8MHz frequency operation, it can perform efficiently. The chip has 44 pins. The clock has 2 timers/counters to keep track of the time. There is a FLASH memory feature on this equipment. A total of 48 programmable I/Os are available on this board.
