STA2500D

Bluetooth͐2;2; V2.1 + EDR ("Lisbon") for automotive applications
  • active Active

The STA2500D is a single chip Bluetooth solution that is fully optimized for automotive applications such as telematics, navigation and portable navigation. Power consumption levels are targeted at battery powered devices and single chip solution brings cost advantages. Manufacturers can easily and quickly integrate the STA2500D on their product to enable a rapid time to market.

STA2500D supports the Bluetooth specification V2.1 + EDR ("Lisbon") and is optimized in terms of RF performance and cost.

The STA2500D is a ROM-based solution targeted at applications requiring integration up to HCI level. Patch RAM is available, enabling multiple patches/upgrades and fast time to volume. The STA2500D’s main interfaces are UART or SPI for HCI transport, PCM for voice and GPIOs for control purposes.

The radio has been designed specifically for single chip requirements, for low power consumption and minimum BOM count.
