Supply voltage and temperature — what they mean for the BOM
The 4V to 24V supply range is wide enough to run directly off USB-C VBUS (5V, 9V, 15V, 20V) or a common system rail without a separate regulator. That saves a DC-DC stage and its associated inductor and caps. The -40°C to 105°C operating range covers industrial environments — motor-drive cabinets, outdoor telecom enclosures, factory-floor HMI panels — where the ambient around the controller can run hot. If your design lives in a climate-controlled office, you have margin to spare.
Memory split: Flash, ROM, and RAM
The 128 KB Flash holds the PD stack and application code; the 32 KB ROM typically carries a bootloader or fixed-function PD firmware, freeing Flash space for custom logic. The 16K x 8 RAM gives you enough buffer for PD message handling and data transfers. For designs that need more data memory, the Cortex-M0 can page external EEPROM over I2C, but the onboard RAM covers most USB PD sink and source scenarios.
Lifecycle and sourcing
The CYPM1115-48LQXI carries an Active lifecycle status from Infineon. No last-time-buy or end-of-life notice is in effect.
