ST72F321BAR7TAE Product Details

ST72F321BAR7TAE Overview


There is a 64-LQFP package available. The board has 48 I/Os. Using the Mounting Type Surface Mount, the MCU is mounted on PCB. A 8-Bit core is used in order to power the IC chip. The type of memory it uses for its program is FLASH. -40°C~85°C TA is the temperature range at which this Microcontroller operates. ST7-series components are electrical components. In the case of this Microcontroller, the memory size of the program is 48KB 48K x 8. Microcontroller's a MICROCONTROLLER uPs/uCs/Peripheral IC. IC Chip terminations are 64. As a result, this Microcontroller comes with a 8-bit size. Input voltage for the chip is 5V volts. A total of NO DMA channels are available. This IC part has a memory size of 48kB. There are a number of alternatives to the base part number ST72F32 that you can find. Performing well when operated at frequency 8MHz can be achieved. Using YES PWM channels, the device works. On the chip, there are 64 pins that can be accessed. It comes with 2 timers/counters that can be set up. The pins counted are 64.
