DESCRIPTION
The STLC2500 is a single chip ROM-based Blue-
tooth solution implemented in 0.13 m ultra low
power, low leakage CMOS technology for applica-
tions requiring integration up to HCI level. Patch
RAM is available enabling multiple patches/up-
grades.
The STLC2500's main interfaces are UART for
HCI transport, PCM for voice and GPIOs for con-
trol purposes. The Radio is designed for the single
chip requirement and for drastic power consump-
tion reduction.
