Features & Applications

The CY8C29666-24LTXI is a part of CY8C29 Series Microcontroller. It has 2 Kilo Bytes RAM and 32 KB of Flash PSoC Programmable System-On-Chip Memory. It has an Operating Temperature of –40 °C to +85 °C. Available in QFN-48 Package.

The PSoC family consists of many Programmable System-on-Chip Controller devices. These devices are designed to replace multiple traditional MCU-based system components with one, low cost single-chip programmable device. PSoC devices include configurable blocks of analog and digital logic, as well as programmable interconnects.
