This document introduces the features and characteristics of STA2500D Bluetooth™ V2.1 + EDR ("Lisbon"), including the Ericsson technology licensing baseband core (EBC), the Bluetooth ™ specification compliance, the HW support for packet types, the AFH and CQDDR, the "Lisbon" features, the transmit power, the HCI, and the pitch-period error concealment (PPEC).
The STA2500D is a single‑chip Bluetooth V2.1 + EDR solution optimized for automotive applications such as telematics and navigation. It integrates an ARM7TDMI core, on‑chip RAM/ROM, and supports multiple digital interfaces (UART, SPI, PCM, I²C) and up to 10 programmable GPIOs.
The document provides absolute maximum ratings, operating ranges, clock specifications, power consumption figures, pinout details, functional block diagrams, and package information for the LFBGA48 package, along with ordering codes and revision history.
