The CY8C20437-24LQXIT is a capacitive-sensing controller from the CapSense® Controllers series with an M8C core. Supply range is 1.71 V to 5.5 V; operating temperature is -40°C to 85°C.
The 29 I/O lines in a 32-QFN package support a capacitive-sensing panel layout.
The difference is the packaging format: the CY8C20437-24LQXIT is supplied in Tape & Reel (TR) and Cut Tape (CT), while the CY8C20437-24LQXI is typically offered in tray packaging. The silicon and specifications are identical.
No. The CYPD2122-24LQXIT is a USB Type-C controller from the EZ-PD™ CCG2 series with an ARM Cortex-M0 core, 32 KB flash, and USB interface. It is a different device class (USB PD vs. capacitive sensing) and is not a functional replacement for the CY8C20437-24LQXIT.
