It integrates CapSense touch sensing, an LCD drive controller, and a 12-bit SAR ADC (8 channels) plus two IDACs, all in a 44-pin TQFP package.
At 24 MHz the Cortex-M0 delivers enough cycles for sensor polling, serial protocol handling, and simple control loops. If your application needs faster data processing or higher PWM resolution, the sibling CY8C4245LQI-483 runs at 48 MHz — double the clock — with the same peripheral set and package options.
Memory sizing for firmware and data
16 KB Flash and 4 KB SRAM suit firmware for HMI front-ends, capacitive touch interfaces, or basic sensor nodes. The 4 KB SRAM is the working memory budget — enough for a few UART buffers and a modest state machine, but tight for large lookup tables or frame buffers.
Peripherals that reduce external BOM
CapSense eliminates dedicated touch-controller ICs for up to 36 capacitive channels. The LCD drive supports segment displays directly.
Housed in a 44-TQFP (10x10 mm) with 36 I/O brought out, this part is a surface-mount fit for standard reflow.
Listed as Active by Infineon, so no last-time-buy risk for new designs. The part is ROHS3 compliant.
