CY8C4025LQI-S412 PSoC 4 Arm Cortex-M0 CapSense MCU
The CY8C4025LQI-S412 is a programmable embedded system-on-chip from Infineon Technologies, featuring a 32-bit Arm® Cortex®-M0 CPU core operating at up to 16 MHz. It is part of the PSoC® 4 programmable system-on-chip family, which uniquely integrates configurable analog and digital peripheral functions with a microcontroller, allowing for highly flexible and customized designs. The device includes 32KB of Flash memory, 4KB of SRAM, and operates from a 1.71V to 5.5V supply range, supporting direct battery operation. Key features include CapSense® capacitive touch-sensing technology, a 12-bit 1-Msps SAR ADC, and programmable digital logic blocks. Its core value proposition is enabling the consolidation of multiple discrete components—such as an MCU, analog front-end, and digital logic—into a single chip, reducing system cost, size, and power consumption.
The CY8C4025LQI-S412 is built around a high-performance 32-bit Arm Cortex-M0 processor, offering a balance of power and efficiency. It integrates 32KB of code Flash with 4KB of SRAM for data. Its standout feature is the programmable analog and digital fabric: it includes four reconfigurable Universal Digital Blocks (UDBs) for custom logic, a 12-bit 1-Msps ADC with 10 input channels, two op-amps, and a low-power comparator. It features CapSense for up to 35 capacitive touch-sensing buttons/sliders. Communication interfaces include two SCBs (Serial Communication Blocks) configurable as I2C, SPI, or UART, and a USB Full-Speed 2.0 device interface.
