Description
The SS1102C is a CMOS integrated solution for direct sequence spread spectrum
digital wireless data communication applications. The chip performs all CPU, baseband
modem and peripheral control functions. A baseband spread spectrum modem, a
microcontroller, and I/O interfaces are integrated into a single chip. The RF interface is
suitable for most RF module designs. A low speed link data path allows for supervisory
and setup functions, while the communication channel is used for full duplex data
transmission.
The chip can be delivered in the 52-pin or 100-pin package. The 100-pin version has an
interface to the external EPROM. The 52-pin version is a mask version of the chip.
