Product details

CapSense controller with M8C core and 8 KB flash

The CY8C20437-24LQXIT is a capacitive-sensing controller from the CapSense® Controllers series with an M8C core. It integrates 8 KB of flash program memory and 1K x 8 of RAM, with 29 I/O lines and I²C/SPI interfaces. Supply range is 1.71 V to 5.5 V; operating temperature is -40°C to 85°C.

Supply voltage flexibility and I/O count

Supply range is 1.71 V to 5.5 V. The 29 I/O lines in a 32-QFN package support a capacitive-sensing panel layout.

Lifecycle and compliance

The CY8C20437-24LQXIT carries an Active lifecycle status and is ROHS3 compliant.

Frequently asked questions

What is the difference between the CY8C20437-24LQXIT and the CY8C20437-24LQXI?

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.

Is the CYPD2122-24LQXIT a functional second-source for the CY8C20437-24LQXIT?

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.
