TC6216M General Description

TC6216M is a stand-alone 16 ports 10/100 unmanaged switch controller designed for low cost high performance solutions. In addition to the basic functions of unmanaged switches it provides features usually associated with managed switches, at very high performance levels. TC6216M offers full wire-speed switching on all 16 ports, self-learning of up to 16K MAC addresses, highly optimized flow control for full and half duplex, evolved traffic priority services, flexible trunking capabilities.

A store-and-forward switching method using a non-blocking architecture is implemented within TC6216M to improve the availability and bandwidth. The chip embeds a 512 Kbytes SSRAM packet buffer so the only external components required are the physical layer transceivers. Normal, high and very high priority queues are mplemented for each transmission port.

The chip contains IEEE 802.3 MAC functions for 16 ports supporting both 10 Mbit/s and 100 Mbit/s data rates. All ports are full and half duplex capable. Each port has its dedicated receive and transmit FIFO's with necessary logic to implement flow-control for both duplex modes. TC6216M utilizes PAUSE frames as defined in IEEE 802.3x for full duplex flow control, and executes backpressure for half duplex mode. No packet will be lost when flow control is operational.

TC6216M provides leading edge QoS with three levels of priority. The priority can be checked via layer 2 (802.1Q VLAN Tagging) and/or layer 3 (IP Header TOS bits). Port based priority is also provided to enable user selectable traffic prioritization. Port based priority ensures transmission with precedence for all packets incoming from selected port(s). This feature allows effective video switching in multimedia applications and improved support for voice over packet applications.

The chip handles a 16K MAC address-lookup table with searching, self-learning, automatic aging, at a very high speed. Forwarding rules are implemented according with IEEE 802.1d specifications. TC6216M also provides filtering capability for bad packets, only good CRC and valid sized packets will be forwarded.

Larger switches can be produced using TC6216M's trunking capabilities. Two trunk groups of up to four ports each can be setup with TC6216M. Several load balancing schemes are provided through pins and EEPROM configuration.

An external EEPROM device can be used to configure the TC6216M at power-up. Compared with pin configuration interface, the EEPROM extends the chip's configuration capability with new features and provides a jumperless configuration mode using a parallel print port interface for reprogramming. TC6216M can make effective use of most of its features without using the external EEPROM.

TC6216M uses an MDIO master entity for PHY autonegotiate mode polling and link status monitoring. Before xtracting the autonegotiation result the chip advertises full duplex flow control ability on each port and restarts the autonegotiation.

Effective broadcast throttling based on both broadcast buffer memory utilization and broadcast bandwidth can be
performed by TC6216M.

TC6216M achieves full performance at 50 MHz clock frequency. It is packaged in 208 PQFP.
