CY8C3446AXI-105 Product Details

CY8C3446AXI-105 Overview


Packaged in a 100-LQFP format, this MCU is available in a compact size. There are 62 I/Os on the Microcontroller. It is important to note that the Microcontroller has a Surface Mount mounting type. 8-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 PSOC® 3 CY8C34xx series includes this electrical component. There is 64KB 64K x 8 bytes of program memory in MCU, which corresponds to the size of the program. With a 8051 Core processor, MCU is equipped with the latest technology available. During the manufacturing process, 100 terminations were applied to the IC chip. The MCU chip's supply output is 3.3V volts. 64kB memory size belongs to the Chip part. Alternatives can be found by looking at the base part number CY8C3446. In the case of 50MHz frequency operation, it can perform efficiently. The chip has 100 pins. The clock has 4 timers/counters to keep track of the time. 100 pins are counted on this board.
