AT91SAM7SE256B-CU Product Details

AT91SAM7SE256B-CU Overview


Packaged in a 144-LFBGA format. A total of 88 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 16/32-Bit. The type of its program memory is FLASH. In this Microcontroller, temperature is controlled within the range -40°C~85°C TA. A SAM7SE series electrical component is used in this application. This program has a program memory of 256KB 256K x 8 bytes, which is the size of the program. With a ARM7® Core Processor, Microcontroller is fast and efficient. ICs for MICROCONTROLLER, RISC uPs/uCs/peripheral parts. There are 144 terminations on the IC chip, which means there are 144 terminations on the integrated circuit chip. In addition, MCU chip comes with a 32-bit size. Microcontroller chip has outputs of 1.8V volts. The system has YES channels for DMA communication. There is 256kB memory size assigned to the part. Alternatives can be found by searching through the base part number AT91SAM7SE256 to find them. At a frequency of 55MHz, Microcontroller can operate efficiently. This MCU Chip uses YES PWM channels to operate. Chips have 144 pins. There are 3 timers/counters in this device. The ARM7 CPU family is embedded in the device, so it can handle a wide range of operations. It is equipped with a ARM core architecture which is integrated into it. It consists of 8 Channel channels in total for the ADC.
