Features and Applications

The CY8C27443-24PVXIT is a 8-Bit Microcontroller with 256 B RAM and16 kB Flash, available in surface mount SSOP-28 package.

The PSoC family consists of many programmable system-on-chip controller devices. These devices are designed to replace multiple traditional microcontroller unit (MCU)-based system components with one, low-cost single-chip programmable device.
