PCF7952ATT/M1CC15118 NXP UHF RF transmitter IC

The PCF7952ATT/M1CC15118 is a UHF-band RF transmitter integrated circuit (IC) manufactured by NXP Semiconductors, designed for secure wireless communication in automotive and industrial applications.    This chip operates within the 300–450 MHz frequency range, supporting high-speed data transmission with low power consumption.    Its 24-pin TSSOP (Thin Shrink Small Outline Package) ensures compact integration into PCB layouts, while its robust temperature tolerance (-50°C to 130°C) and RoHS compliance make it suitable for harsh environments.    The IC integrates 512B RAM, 1kB EEPROM, and 8kB ROM, enabling on-chip data storage and processing for applications like remote keyless entry (RKE), tire pressure monitoring systems (TPMS), and active tag-based access control.

PCF7952ATT/M1CC15118 Applications

The PCF7952ATT/M1CC15118 is widely used in automotive security systems, including:

● Remote Keyless Entry (RKE): Enables wireless locking/unlocking of vehicle doors with encrypted communication.

● Tire Pressure Monitoring Systems (TPMS): Transmits real-time pressure data to the vehicle's dashboard.

● Active Tag Systems: Facilitates hands-free access control for parking gates or building entry points.

● Industrial Asset Tracking: Supports low-power RFID-like tagging for logistics and inventory management.
