Product details

PSoC 5 at 67 MHz — what the core speed buys you

Memory budget: 128 KB Flash, 32 KB SRAM, 2 KB EEPROM

Program memory is 128 KB Flash, backed by 32 KB SRAM and a separate 2 KB EEPROM block.

Supply range and power tree simplification

Peripheral integration: CapSense, USB, LCD, and more

On-chip CapSense eliminates a dedicated touch controller for up to 38 capacitive-sensing channels. The USB interface (full-speed device) handles HID or CDC class connections without an external PHY. LCD drive supports direct segment LCD panel connection, saving a driver IC. DMA offloads data movement between peripherals and memory. These integrated blocks reduce BOM count and board area significantly compared to a discrete MCU + touch + USB + LCD driver solution.

For volume production, this part can be sourced through independent channels against an RFQ.

Frequently asked questions

Is CY8C5667LTI-LP041 obsolete or nearing end of life?

No, the CY8C5667LTI-LP041 has an active lifecycle status per Infineon. There is no end-of-life notification or last-time-buy schedule in effect. It remains a viable choice for new designs.

What is the speed rating of CY8C5667LTI-LP041?

The core runs at 67 MHz. That is the maximum clock from the internal oscillator or an external source. At 67 MHz the Flash requires zero wait states for most instructions; the Cortex-M3 pipeline handles single-cycle multiply and branch efficiently at this speed.
