It is a 32-bit single-core device with 27 I/O lines, a single 10-bit ADC, and an internal oscillator that eliminates the external crystal in many designs. ## 1.71 V supply rail and temperature range ## CapSense and peripheral set CapSense support is built into the peripheral block, alongside brown-out detect, reset, LVD, POR, PWM, and WDT. The connectivity set includes I²C, IrDA, LINbus, Microwire, SmartCard, SPI, SSP, and UART/USART, covering most serial-interface needs for a cost-sensitive embedded controller. The single 10-bit ADC is adequate for basic analog sensing — temperature, voltage monitoring, or slow sensor inputs — but designs requiring multiple high-resolution channels should look at the PSoC 42xx siblings with 12-bit SAR ADCs. ## Sourcing and date-code traceability With an Active lifecycle status, this part is not subject to last-time-buy risk. For buyers concerned with provenance, the laser-etched date-code and top-marking on each reel can be cross-checked against the manufacturer's plant records — a standard counterfeit screen for any PSoC 4 device. Reel and tray quantities vary; confirm the packaging format at quote time.","metaTitle":"Cypress CY8C4025LQI-S402 PSoC 4 MCU, ARM Cortex-M0+, 24 MHz","metaDescription":"Infineon/Cypress CY8C4025LQI-S402 PSoC 4 MCU: ARM Cortex-M0+, 24 MHz, 27 I/O, CapSense, I2C/SPI/UART, 1.71V supply, -40 to 85°C.
