Description

The STLC2500C is a single chip ROM-based Bluetooth solution implemented in 0.13 μm ultra low power, ultra low leakage CMOS technology for mobile terminal applications requiring integration up to HCI level. Patch RAM is available, enabling multiple patches/upgrades. The STLC2500C offers multiple interface options. The radio has been designed specifically for single chip requirements for minimal consumption and BOM count.

Features

■ The lowest power consumption by design and technology (see Table 1)

■ World best EDR throughput (see Table 1)

■ World most performing BT-WLAN coexistence support for several BT/WLAN coexistence algorithms (i.e. 2/3/4-wire PTA, in a very flexible and parametrical way to optimize voice and data quality over Bluetooth and WLAN)

■ Superior voice quality

– Pitch-Period Error Concealment (PPEC) for improved speech quality (in the vicinity of interference)

■ Extended range

– Tx output power up to 8 dBm

■ Pre-calibrated RF
