It belongs to the CY8C28xxx series, a configurable mixed-signal family that packs a 4-channel 14-bit ADC and a 4-channel 9-bit DAC on the same die as the digital logic. That combination — a programmable analog front end alongside a standard MCU — is what sets this part apart from plain 8-bit controllers: it can handle sensor conditioning, signal scaling, and simple control loops without an external op-amp or ADC chip. ## Industrial temperature grade and 3 V supply rail The supply is a nominal 3 V rail, so the design needs a regulated 3 V source; the LVD (low-voltage detect) peripheral can monitor the rail and trigger a reset if it droops. The internal oscillator means no external crystal is required for the core clock, saving two pins and a few cents on the BOM. The device brings I²C, IrDA, SPI, and UART/USART interfaces, which cover the common serial buses for sensor readout, display communication, and debug logging. The 24 I/O lines are enough for a medium-complexity control panel or a multi-sensor aggregator. On-chip POR, PWM, and WDT round out the supervisory and timing functions, reducing the need for external watchdog or reset ICs. Cypress lists the CY8C28452-24PVXI as Active. No last-time-buy deadline, no successor to chase — just a standard procurement path through distribution.","metaTitle":"Cypress CY8C28452-24PVXI PSoC1 MCU, 8-Bit M8C, 24 MHz","metaDescription":"Cypress CY8C28452-24PVXI PSoC1 8-bit M8C MCU at 24 MHz with 4x14b ADC and 4x9b DAC.
