ST72F521AR9TCE Product Details

ST72F521AR9TCE Overview


Packaged in a 64-LQFP format. A total of 48 I/Os are on the Microcontroller. Surface Mount is the mounting type of the Microcontroller that is attached to the panel. This Microcontroller is based on a core called 8-Bit. The type of its program memory is FLASH. In this Microcontroller, temperature is controlled within the range -40°C~125°C TA. A ST7 series electrical component is used in this application. This program has a program memory of 60KB 60K x 8 bytes, which is the size of the program. ICs for MICROCONTROLLER uPs/uCs/peripheral parts. There are 64 terminations on the IC chip, which means there are 64 terminations on the integrated circuit chip. In addition, MCU chip comes with a 8-bit size. Microcontroller chip has outputs of 5V volts. The system has NO channels for DMA communication. There is 60kB memory size assigned to the part. Alternatives can be found by searching through the base part number ST72F52 to find them. At a frequency of 8MHz, Microcontroller can operate efficiently. Chips have 64 pins. There are 2 timers/counters in this device. In total, it has 64 pins. It consists of 16 channels in total for the ADC. This device uses 4 PWM channels to generate the voltage. 1 channels of I2C have been incorporated into the design of the part.
