AT91SAM7S321-MU Product Details
AT91SAM7S321-MU Overview
Packaged in a 64-VFQFN Exposed Pad 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. 16/32-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 SAM7S series includes this electrical component. There is 32KB 32K x 8 bytes of program memory in MCU, which corresponds to the size of the program. With a ARM7® Core processor, MCU is equipped with the latest technology available. 32kB memory size belongs to the Chip part. Alternatives can be found by looking at the base part number AT91SAM7S321. In the case of 55MHz frequency operation, it can perform efficiently. The chip has 64 pins. The clock has 3 timers/counters to keep track of the time. There is a FLASH memory feature on this equipment. With ARM core architecture, it offers high performance. A total of 32 programmable I/Os are available on this board.
