General Description

The ISSC IS1002 is a highly integrated Bluetooth baseband controller providing capability for high data rate, short-range wireless communications in the 2.4 GHz ISM band. It is fully compliant with version 1.1 of Bluetooth specification and some important BT1.2 features. Specially engineered for low power consumption and cost effective solution, the ISSC IS1002 integrates a baseband controller, HCI controller, and Audio controller. It also integrates a Turbo 8051 processor with 160K mask ROM for program memory and 32K SRAM for data memory.
