STLC1502

STMicroelectronics' STLC1502 is a high performance VoIP processor specially targeted for the time effective design of IP-Phones and analog gateway applications bundled with a comprehensive embedded software solution.

When used in the Enterprise LAN IP Phone space,this device STLC1502 enables the augmentation and replacement of raditional telephone systems with network based communications systems running over local and wide area IP networks. To design an IP phone,the only other parts required will be an analog interface,some optional Flash memory for upgradable software and Fast Ethernet physical layer devices.The ST complete IP Phone reference design includes standards compliant Application Programming Interfaces (APIs), protocol management software and software development tools.

The STLC1502 also has all the proper interfaces to be a cost effective solution for Small Gateway applications.ST also offer a complete SW reference design for Small Gateway applications.

Hence, the STLC1502 enables a superior and cost effective platform development for IP-phones as well as voice gateway applications, providing developers with a low risk, rapid time to market solution.

The STLC1502 integrates low power D950 DSP with a ARM7/TDMI MCU and a dual port 10/100 Base-T switched Ethernet media access control interface.

The main characteristics of the STLC1502 IP processor are as follows:
   • HCMOS7 technology
   • Power supply: Core 2.5 V and I/O: 3.3 V
   • Industry standard 32-bit RISC microprocessor (ARM7/TDMI core)
