Description

The S3C852B is a low power CMOS 8-bit micro controller, which has a micro control unit (MCU), Caller ID on Call Waiting (CIDCW) receiver, tone generator, etc. The S3C852B single-chip microcontroller is fabricated using a highly advanced CMOS process. Its design is based on the powerful SAM87RC CPU core. Stop and Idle power-down modes were implemented to reduce power consumption. The S3C852B is used for receiving physical layer signals like Bellcore's CPE Alerting Signal (CAS) and similar evolving systems and also meets the requirements of emerging Caller ID on Call Waiting (CIDCW) services. In addition, two different signal inputs are available to support Tip/Ring and Hybrid connectivity. The S3C852B also includes a 1200 baud Bell 202/V.23 compatible FSK data demodulator, a ring or line reversal detector, a Stutter Dial Tone detector and a tone generator. Tone generator is capable of generating FSK signal and dual tone signals such as CAS, DTMF to support various applications such as short messaging service (SMS). The size of the internal register file is logically expanded, increasing the addressable on-chip register space to 1808 bytes. A flexible yet sophisticated external interface is used to access up to 64-Kbytes of program and data memory. The S3C852B is a versatile microcontroller that is ideal for use in a wide range of following applications.
