TLC252CPWR

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 STLC2500s main interfaces are UART for HCI transport, PCM for voice and GPIOs for control purposes.
The Radio is designed for the single chip requirement and for drastic power consumption reduction.
FEATURES
