CY8C21434B-24LQXI Product Details

CY8C21434B-24LQXI Overview


Packaged in a 32-XFQFN Exposed Pad format. A total of 28 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~85°C TA. A PSOC®1 CY8C21xxx series electrical component is used in this application. This program has a program memory of 8KB 8K x 8 bytes, which is the size of the program. With a M8C Core Processor, Microcontroller is fast and efficient. There are 32 terminations on the IC chip, which means there are 32 terminations on the integrated circuit chip. In addition, MCU chip comes with a 8-bit size. Microcontroller chip has outputs of 5V volts. There is 8kB memory size assigned to the part. Alternatives can be found by searching through the base part number CY8C21434 to find them. At a frequency of 24MHz, Microcontroller can operate efficiently. Chips have 32 pins. In total, it has 32 pins. The M8C CPU family is embedded in the device, so it can handle a wide range of operations. As an example, one of the additional features that you can use is ALSO OPERATES AT 2.7V AND 3.3V SUPPLY.
