The Texas Instruments AR7 or TI-AR7 is a fully integrated single-chip ADSL CPE access router solution. The AR7 combines a MIPS32 processor, a DSP-based digital transceiver, and an ADSL analog front end.
Ownership history[edit]
In 2007, TI sold its DSL business to Infineon.[1][2]
In 2009, Infineon Technologies spins off its wireline division to Lantiq.[3]
On November 6, 2009, Lantiq announced that it became a standalone company.[4]
Features[edit]

- ADSL PHY subsystem based on TI C62x DSP, with integrated transceiver, codec, line driver, and line receiver
- Hardware accelerated ATM Segmentation and Reassembly (SAR)
- Integrated IEEE 802.3 PHY
- Two IEEE 802.3 MACs with integrated Media Independent Interface (MII) and Quality of Service (QoS)
- Integrated USB 1.1 compliant transceiver (slave only)
- Two VLYNQ interfaces for compatible high-speed expansion devices
- Two 16c550 compatible UARTs
- EJTAG, GPIO and "Flexible Serial Interface" (FSER) interfaces
- 4 KiB PROM (0xBFC00000) and 4KiB RAM (0x80000000) on the chip for boot purposes
