New Orleans - Submicron CMOS and silicon germanium carbon (SiGe:C) processes shared the spotlight with a new security processor at Motorola's Smart Networks Developer Forum, held here, as the company launched a plethora of chips and revealed plans for others.
The DSP56321 digital signal processor, samples of which should be ready by the third quarter, is the first Motorola product manufactured on the recently announced HiPerMOS7 (HiP7) 0.13-micron system-on-chip CMOS platform process. Also planned for third-quarter sampling and fourth-quarter delivery is a new generation of SiGe:C timing devices with propagation delays that are said to be more than 50 percent lower than those available from bipolar processes. Separately, Motorola's Phoenix-based Semiconductor Products Sector introduced a SiGe:C-based low-noise amplifier (LNA).
Motorola entered the security processor market about 15 months ago and is now introducing its second-generation product, the 1-Gbit/second MPC190, observed Larry Walker, director of strategies for Motorola's Networking and Computing Systems Group, the Austin, Texas-based unit that sponsored the forum.
In addition to the DSP, the timing products and the security processor, Motorola introduced a serial interconnect transceiver, two PowerPC-based host processors and a family of low-voltage clock devices. The company also said it has boosted the performance and functionality of its PowerQuicc II communications processors.
The DSP56321 DSP, the newest member of Motorola's DSP56300 family, is code- and footprint-compatible with earlier models but offers half again as much memory and a one-third performance increase over the older DSP-56311. It runs at 200 MHz at 1.5 volts and features 192k 24-bit words of on-chip memory. An enhanced filter co-processor (EFCOP) runs filter algorithms in parallel with core operations in echo cancellation and other wireless infrastructure and networking communications applications. The DSP is expected to come in at less than $80 each in 10k quantities.
The forthcoming family of SiGe:C-based clock drivers will offer reduced noise, for lower clock jitter and more precise system timing. Motorola is sampling a family of clocks manufactured on a conventional process. The clocks are optimized for 2.5 V but are backward-compatible with 3.3-V designs. They include frequencies to 250 MHz and output skew to less than 100 ps, with low jitter. Deliveries are scheduled for the fourth quarter. Prices weren't available.
Motorola's Semiconductor Products Sector (Phoenix) separately introduced its first SiGe:C standard product for the merchant market, the MBC13720 low-noise amplifier, which features an on-chip bypass switch. Applications for the LNA include PCS 1900 MHz cellular telephones as well as 900- and 2,400-MHz industrial, Scientific and medical (ISM) band designs. The bypass switch improves dynamic range for receiver designs while maintaining a low insertion loss. It also helps conserve board space and reduce system costs. The MBC13720 comes in an SOT-363 surface-mount package and is priced at $1.50 in 10k quantities.
The MPC190 security pro-cessor can offload processing of the IP Security (IPsec), Internet Key Exchange (IKE), Secure Sockets Layer/Transport Layer Security and Wireless Transport Layer Security protocols used in broadband access, routers, Web servers, WAP gateways and other access applications. Public key performance can reach 1,000 IKE "handshakes" per second with elliptic curve cryptography and 520 IKE handshakes/second using 1,024-bit RSA. System performance is supported up to 1.1 Gbits/s for Data Encryption Standard (DES) bulk data encryption and 1 Gbit/s on SHA-1 authentication. The part is packaged in a 252-pin mold-array-process ball-grid array and is expected to be priced around $75 in 10k quantities. Samples should ship in the fourth quarter.
The WarpLink MC92610 quad 2.5-Gbit serial interconnect transceiver includes four 2.5-Gbit (3.125-Gbaud) point-to-point links for an aggregate throughput of 20 Gbits/s. Each transceiver has redundant, independently selectable transmit and receive I/Os. HSTL Class 1 DDR source-synchronous parallel interfaces are said to allow efficient integration with system logic. Power consumption is less than 1.5 W when all transceivers are operating at full speed, said Brian Wilkie, vice president and general manager of Motorola's Computing Platform Division.
Pricing is pegged at about $62.50 in 10k quantities. Samples are scheduled for the third quarter and production for the fourth quarter.
Motorola's two new PowerPC host processors are the MPC8245 and MPC7440. The company also introduced a 450-MHz version of its MCP-7410 processor.
The MPC8245 combines a 32-bit 603e processor core; a 133-MHz memory controller that can support up to 2 Gbytes; and a 32-bit, 66-MHz PCI interface with a 16-kbyte data memory and a 16-kbyte instruction cache. It is sampling now and is slated to go into production before the end of June. The processor comes in a 352-pin TBGA and will be priced at around $29 in 10k quantities for a 266-MHz version and at $39.60 for 300-MHz performance.
The MPC7440 is geared for speeds of 600 and 700MHz . It has a core voltage of 1.5 V and typical power dissipation of 11.4 W at 600 MHz. It includes 256k of L2 cache, a seven-stage pipeline and both a 60x legacy and an MPX system bus. The latter is said to be capable of 1,064-Mbyte/second sustained bandwidth performance, or nearly four times the bus performance of earlier processors.
The 450-MHz MPC7410 typically uses 3.5 W running at 1.5 V. It includes a backside L2 cache, an AltiVec vector-processing engine and an MPX bus.
The MPC7440 and MPC-7410 are both expected to sample in the third quarter. Prices are $159 in 10k quantities for the 700-MHz MPC7440 and $99 for the MPC7410.
Finally, Motorola added the MPC8264, MPC8265 and MPC8266 to its PowerQuicc line of communications processors. The MPC8264 includes integrated transmission convergence (TC) layer capabilities and microcode to deliver inverse multiplexing for asynchronous transfer mode functionality. The MPC-8265 offers an optional 32-bit, 66-MHz PCI interface in place of the local bus, and the MPC8266 combines the features of both.
Prices in 10k quantities for 200-MHz versions are $123, $105 and $133, respectively.
