San Jose, CA — (press release excerpt) — Toshiba America Electronic Components, Inc. (TAEC) today announced development of a new 64-bit MIPS-based microprocessor to enable a new-generation of cost effective digital consumer products that can benefit from 64-bit processing power and specialized peripherals. Designated the TX4925, the device provides built-in Flash memory support, plus essential peripheral interfaces required by many digital consumer applications such as a PCMCIA interface, PCI controller, and AC-Link controller. Target applications include broadband audio/video, Internet appliances, mobile applications and residential security gateways.

Features include . . .

• 200 megahertz processor with a 1.5 volt core and a 3.3V I/O; the core incorporates an MMU, plus hardware multiply accumulator (MAC) and single/double-precision floating-point unit (FPU); the instruction set supports MIPS I, II and III instructions plus MIPS IV prefetch, multiply/add and debug instructions.

• An integrated static direct random access memory (SDRAM) controller can handle four channels of DIMM SDRAM in configurations up to two gigabytes. An external bus controller supports six channels of read only memory (ROM), Flash, SRAM and memory-mapped I/O devices.

• A PCI bus controller supports up to four external bus masters. It complies with revision 2.2 of the PCI Local Bus Specification with PCI booting.

• PCMCIA interface, which can be used with radio frequency modules in broadband wireless communications

• Flexible support for external memories that include new NAND Flash memory and Micron's SyncFlash memory

• A direct memory access (DMA) controller supports four independent channels.

• I/O includes a two-channel serial port, parallel I/O port, serial peripheral interface, high-speed serial concentration highway interface, three-channel timer/counter and 44-bit up counter real time clock, a AC97 and audio link interface and an AC-Link.

• Also included are two power-down modes and a reduced frequency function that enables the CPU clock frequency to be reduced by a factor of four reducing overall power consumption.

Real-time operating systems that will be supported include embedded Linux, Wind Rivers Systems' VxWorks/Tornado II package, and ATI Nucleus.

The TX4925 is scheduled to sample in February 2002 at $25 in 10,000 piece quantities
