Editor's View -- Exclusive to Electronic Design UPDATE ********************** New Solutions For Embedded Controllers By David Bursky, Editor-at-Large Designers were treated to a veritable feast of advances in silicon, software, and system-level hardware at this year's Embedded Systems Conference (April 23-25) in San Francisco. One of the biggest challenges most designers admitted they faced was the ever increasing time it takes to develop their hardware and software solutions. The reason: the increasing complexity of the applications they are tackling. Microcontroller vendors try to counter this increasing development time by offering broader product offerings, hoping that one member of their product family will have a feature set close enough to match the user's requirements. Although that tactic provides the designer with a wide set of low-cost choices, it burdens the silicon vendor with the challenge of continually creating more family members until the product family becomes unwieldy. That has been changing, however, as electronic design automation tools, reusable blocks of intellectual property (IP), FPGA technology, and ASIC processes get better and let designers leverage all of them simultaneously to rapidly develop new system-on-a-chip solutions. Enhanced design tools enable engineers to more quickly define and craft the logic for new embedded processors, and IP libraries save valuable design time, while FPGA technology permits faster prototyping and even limited to mass production of various solutions. Advances in ASIC processes, meanwhile, allow ever more complex subsystems to be squeezed onto a small chip. Mask and other development costs of a full ASIC solution can get out of hand, though, unless the final chip will sell in the millions of units per year. So there is a tug of war, of sorts, festering between off-the-shelf microcontrollers, the use of the somewhat inefficient FPGA approaches, and full-ASIC approaches. A fourth design option, which is still in its embryonic stage, is the use of what a few companies call an ASIC platform. Several architectural approaches loosely fall into this "platform" category, but they all claim shorter development time than a full ASIC, lower nonrecurring engineering costs than full ASICs, and a more area-efficient design than FPGAs (see "Fast Turnaround ASIC Platforms Speed Complex Chips To Market," Electronic Design, February 17, 2003, p. 40). This emerging area will leverage the best aspects of the various technologies to provide designers with new options for crafting custom solutions. The challenge will be to provide the solutions cost-effectively and to rapidly meet the ever shorter time-to-market demands.

News -- From The Editors ********************** ***Low-Power, Pseudostatic RAMs Aim At New Cell Phones Targeted at 2.5 and 3G wireless handsets and other portable applications, the CellularRAM family of low-power, pseudostatic memories has been jointly defined and released by Cypress Semiconductor Corp., Infineon Technologies AG, and Micron Technology Inc. The memories offer a 16-bit data path and come with either an asynchronous or burst interface. The 32-Mbit version operates at clock rates of up to 104 MHz and has an initial latency of 70 ns. The chips can achieve a peak bandwidth of up to 208 Mbytes/s (1.5 Gbits/s). The memories' cost/bit ratio will be lower than current solutions, and they will be drop-in compatible with asynchronous low-power SRAMs. Micron is currently sampling 32- and 64-Mbit memories, with full production expected next quarter. Infineon is sampling the 32-Mbit device and plans to go into full production next quarter. Cypress plans to sample the 32-Mbit chip in the first half of 2004. A 128-Mbit device is planned for late in 2004. Additionally, Infineon plans to offer CellularRAM products in known-good die wafer formats so that memory subsystems can be tuned to specific application requirements.

Housed in a 16-pin SOIC, the Si2401 ISOmodem is part of a two-chip set that additionally includes the Si3010 programmable global line interface, also in a 16-pin SOIC. Chip-set pricing begins at $7.33 in lots of 10,000. The bill-of-materials cost is approximately $0.50 for the external components, not including the pc board. Power consumption for the Si2401 is less than 30 mW. Contact Silicon Laboratories at http://lists.planetee.com/cgi-bin3/DM/y/eQoS0DJhUf0EmQ0BACF0A1 ***TCXO Draws Less Than 7 mW Drawing less than 2 mA (under 7 mW from a 3.3-V supply), the surface-mountable ER family of temperature-compensated crystal oscillators (TCXOs) is a good fit for battery-powered applications. The oscillators develop a user-specified output of 12 to 19.68 MHz and are compatible with HCMOS and transistor-transistor-logic families. Jitter (phase noise) is a low -125 dBc/Hz at a 1-kHz offset. Additionally, they feature mechanical and electrical frequency trimming of ±3 ppm and ±4 ppm, respectively. Long-term aging is typically less than ±1 ppm/year. The oscillators maintain ±2.5-ppm frequency accuracy from -30°C to 70°C. Based on hi-Q quartz crystals, they're available on tape and reel for automated circuit-board assembly. The devices measure 11.4 by 9.6 by 2.5 mm. They cost $4 each in OEM lots and are available from stock to four weeks. Contact MF Electronics Corp. at http://lists.planetee.com/cgi-bin3/DM/y/eQoS0DJhUf0EmQ0BACG0A2 ***Compiler Generator Takes On C++ The CoSy 2003 compiler generation package from ACE Associated Compiler Experts has added C++ support. Developers can use CoSy 2003 to create C++ compilers for a broad range of DSP, NPU, RISC, VLIW, and 8/16-bit processors with minimal work. The new version provides flexible bit-field support and the aiSec graphical visualization package. New optimizations include software pipelining and support for parallel execution units. Pricing starts at $250,000. Contact the company at http://lists.planetee.com/cgi-bin3/DM/y/eQoS0DJhUf0EmQ0BACH0A3 ***JVM Now Available For A One-Time Fee PERC, the clean-room J2SE-class Java virtual machine, is now available royalty free. NewMonics' new pricing policy has deployment packages starting at $30,000 per target architecture. Source code is optionally available. It will be interesting to see if other vendors in the JVM space follow this pricing model.
