AT91SAM7SE256B-AU Product Details
AT91SAM7SE256B-AU Overview
The package is in 128-LQFP format. The MCU has 88 I/O ports. There is a mounting type Surface Mount associated with this Microcontroller. This Microcontroller is based on the 16/32-Bit core. There is a memory type of FLASH in its program memory. The temperature range that this Microcontroller operates at is -40°C~85°C TA. The electrical component that you are looking at belongs to the SAM7SE series of components. Microcontroller has abundant program memory size of 256KB 256K x 8. The ARM7® Core Processor powers the device and is one of its key features. This Microcontroller belongs to the MICROCONTROLLER, RISC uPs/uCs/peripheral ICs type. During the manufacture of the IC chip, there is a number 128 of terminations. A 32-bit operation is performed by this part. There is an output of 1.8V volts from the Microcontroller chip. A total of YES DMA channels are available on MCU chip. This MCU is implemented with 256kB memory. AT91SAM7SE256 serves as a base part number to find alternatives. It exhibits good efficiency when it operates at a frequency of 55MHz and it is able to operate at a high frequency. It is possible for the device to work with the motor using the PWM channel YES. It is possible to access the 128 pins on the chip through the 128 pins. It is equipped with 3 timers and counters. It consists of 128 pins. As far as the CPU is concerned, it is embedded with the the ARM7 family of processors. There is a ARM core architecture integrated into it. The device features 8 UART channels. There are a total of 8 Channel channels for the ADC on this board, so it has a total of 8 Channel channels. An 4-channel PWM controller is used by the device. In this device, there's an 1-channel PWM controller.
