Austin, TX — (press release excerpt) — Cirrus Logic today announced the CS89712 System-On-Chip (SOC) for Internet communications devices. The CS89712 is the company's first device to combine a low power, high-performance 74MHz ARM720TDMI Core, 10Mbps Ethernet connectivity (MAC and PHY), built-in LCD controller, plus a wide array of internal peripherals.
The CS89712 simplifies the design and reduces the total system cost of Internet communication systems including H.323 and SIP based VoIP telephones and other communications appliances. The built-in memory management unit (MMU), 8K-bytes of cache, and 48K of SRAM make the CS89712 ideal for customers wishing to incorporate Open Source operating systems, such as Linux.
“We are seeing increased customer demand for open source operating systems and applications such as embedded Linux that allow customers to get to market quickly and with a lower total system cost,” said Jeff Luftig, Cirrus product marketing manager.
In addition to the 74MHz ARM720TDMI Core, the CS89712 includes the following comprehensive suite of system peripherals:
- SDRAM/Flash/SRAM/ROM controller
- 8Kbytes Cache
- On-chip boot-ROM
- 48K internal SRAM
- 10Mb Ethernet MAC & PHY
- LCD controller
- Two UARTs
- Infrared Interface
- Real-Time Clock
The CS89712 is available in a 256-lead PBGA package and is priced at $27.00 in 10k quantities. Samples and Evaluation boards will be available in December.
