KSZ8382Q

KSZ8382 SoC Family Data Brief VLANs, and IGMP v1/v2 snooping for multicast packet filtering. Overview System-on-Chip (SoC) provides a complete solution for IP-based communication for a wide range of applications. The highly integrated SoC has built-in support for interfaces, which reduces the need for external components. The KSZ8382 SoC is the ideal choice for IP-based -reliability and endpoints and is solution robustness that has been proven in commercial, industrial, and automotive applications around the globe. Architecture The KSZ8382 implements a multiprocessor architecture with embedded RISC CPU and powerful DSP, providing a flexible VoIP platform with narrowband and wideband voice processing that enables superior voice quality. The chip features innovative advanced power management including energy efficient Ethernet (EEE), which makes it the only EEE VoIP SoC in the industry that is compliant with the EU regulation on Ecodesign (Directive 2005/32/EC), limiting standby power of devices to less than 1 watt. Benefits Cost-effective: Highly-integrated device significantly reduces the cost of developing IPbased endpoints. Energy efficient: Industry-leading advanced power management greatly reduces cost of operation. Integrated 3-Port Switch: 3-port switch device which enables connection to an additional IP device. Multicast support: Built-in IGMP snooping provides industry-leading support for multicast systems. Voice Quality: Wideband and narrowband codecs provide superior HD voice quality. Applications The KSZ8382 processor enables ODMs, OEMs, and VARs to develop a wide range of IP-based communication solutions including: KSZ8382 Block Diagram extensive integration featuring a highperformance audio subsystem, LCD interface, keypad scanner, memory controllers for both SDRAM and DDR2, and flexible GPIO increases performance and reduces BOM cost. Micrel integrate d lowest-power 10/100 Ethernet switch, implementing critical functionality for IP telephony including IEEE 802.1p priority quality of service (QoS), 802.1Q IP phones Emergency systems Intercom systems Kiosks Paging systems Vending systems Cloud-based services Door systems solution applies to multiple market segments including enterprise, commercial and residential access, security, healthcare, tele-transactions, and cloud-based services. In addition, this solution enables a cost-effective transition from existing analog solutions to digital/cloud services, adding another product life-cycle to installed systems. Firmware Specifications firmware architecture provides ODMs, OEMs, and VARs with a variety of choices in developing their endpoint applications. Channel Density 2 channels Hardware CPU MIPS32 4KEc DSP ZSP400 Keypad interface LCD interface Integrated SSP (SPI/I2C) controller Three inputs for ADC, three outputs for DAC Access to Call Control: Turnkey solution. Developers can leverage the built-in SIP call manager from the endpoint application. Access to Media Transport: Developers who have their own SIP software (or want to implement other call control protocols) can use the RTP/RTCP access for media transport. Access to DSP Resources: Developers who want their own call control and media transport (standards-based or even proprietary) can access the DSP resources directly. Micrel offers world-class support, tools, modules, and customization services in developing cost-effective and compelling applications.
