It comes in an 8-SOIC package with just 5 I/O pins and a single I²C interface. The wide supply range of 1.71V to 5.5V lets it run directly from a lithium cell or a 5V rail without an external regulator. Operating temperature is -40°C to 85°C, so it handles industrial environments like motor-drive auxiliary boards, sensor hubs, or simple actuator controllers. ## Memory and I/O — keep the firmware lean 16 KB Flash and 2 KB RAM are tight. This part is sized for a single control loop, a few configuration parameters, and a small state machine. There is no room for a full RTOS or large data buffers. The 5 I/O pins and single I²C interface mean you are connecting one or two sensors or a simple display — not a multi-peripheral system. Brown-out detect, POR, PWM, and WDT are on-chip, so external supervisor ICs are not needed. ## Active production — no LTB risk for new designs No last-time-buy notice or obsolescence risk. ROHS3 compliant. For a BOM line that needs a small, low-pin-count MCU, this is a safe choice for the next several years. No need to stockpile or hunt surplus. ## Package and supply — fits a 5V or battery-powered board 8-SOIC (0.154\", 3.90mm width) surface-mount package. The 1.71V to 5.5V supply range means it can run from a 3.3V LDO, a 5V logic rail, or a 2-cell alkaline battery stack. Internal oscillator eliminates the external crystal. Mounting is surface-mount only — no through-hole option.","metaTitle":"CY8C4014SXI-420T PSOC 4 MCU, ARM Cortex-M0, 16 MHz, 8-SOIC","metaDescription":"CY8C4014SXI-420T PSOC 4 32-bit MCU, ARM Cortex-M0, 16 MHz, 16 KB Flash, 2 KB RAM, I²C, 5 I/O, -40 to 85°C, 8-SOIC.
