STLC2500 - ST Microelectronics

STLC2500 BLUETOOTH SINGLE CHIP

The STLC2500 is a single chip ROM-based Bluetooth solution implemented in 0.13 m ultra low power, low leakage CMOS technology for applications requiring integration up to HCI level. Patch RAM is available enabling multiple patches/upgrades. The STLC2500's main interfaces are UART for HCI transport, PCM for voice and GPIOs for control purposes. The Radio is d.
