PSD Family Supplies 512 Kbytes Of Flash And 8 Kbytes Of SRAM
The PSD4000 family of programmable system devices (PSDs) provides 100% in-system programmable concurrent flash memory, SRAM, programmable logic, and extra I/O for 16- and 32-bit microcontrollers and DSPs. The first two models, the PSD4135G2 and PSD4235G2, have 512 kbytes of flash, a second concurrent 32-kbyte flash array, and 8 kbytes of SRAM. They also feature a built-in configurable interface for 16- and 32-bit microcontrollers or DSPs, a programmable address decoder, and a small CPLD for chip selects, combinatorial logic, and configurable pin assignments.

Specifically, the PSD4235G2 comes with additional sequential logic in a 3000-gate general-purpose CPLD that has 82 inputs and 24 outputs. This CPLD, then, can supply enough on-chip programmable logic for implementing peripheral functions. The device also allows JTAG chaining during in-system programming.

The PSD4135G2 andPSD4235G2 are available now in an 80-pin TQFP package. Prices for the PSD4135G2 start at $8.35, while the PSD4235G2 starts at $9.75, both in 10,000-unit batches.

Combination Memory Devices Cut Cost, Space, And Power
Three new members of the ComboMemory product family promise highly integrated flash-memory and SRAM solutions. The SST32VF802 combines 8 Mbits of flash memory with 2 Mbits of SRAM, the SST32VF162 combines 16 Mbits of flash memory with 2 Mbits of SRAM, and the SST32VF164 combines 16 Mbits of flash memory with 4 Mbits of SRAM in a multichip package (MCP). These products can replace as many as three discrete components (flash, SRAM, and EEPROM) in traditional cellular phone applications, producing significant cost, space, and power savings. And, they offer a 10-µA standby current.

All three devices include the SoftPartition flash-memory architecture, which lets designers seamlessly partition the data and program code into small, granular 2-kword sectors. They also enable concurrent memory operations, which maximize system throughput. With concurrent memory operations, the products can simultaneously read from or write to the SRAM bank while erasing or programming in the flash-memory bank. The SRAM memory bank can be read or written while the flash-memory bank concurrently performs sector erase, bank erase, or byte program.

In 100,000-unit quantities, the -802 costs $10.50, the -162 costs $13.50, and the -164 costs $15.50. Packaged in a 48-ball TBGA, these devices are sampling now, with volume production slated for June.

Development Platform Speeds Time-To-Market
The Blue Planet development platform is a complete development environment that lets embedded application developers begin programming within hours of receiving the system. Certified for Windows CE, the platform is designed to be a cost-effective approach for handheld computing devices, point-of-sale terminals, control panels, factory automation, and other applications.

All of the components in the platform are production-ready. Developers, then, can bring prototypes and production systems to market faster because they are based on the actual development system.

Each Blue Planet development environment is comprised of an embedded PC-104 form-factor board featuring the Motorola PowerPC 823e processor, a 640-by-480 color LCD with touch-screen panel, an infrared keyboard and trackball, a Windows CE image with the desktop, Pocket Internet Explorer, Pocket Inbox, Pocket Word, and standard Platform Builder demonstration applications. It also boasts 16 Mbytes of flash memory, 16 Mbytes of SDRAM, a network-ready 10BaseT Ethernet controller, one full RS-232C channel, a separate debug channel, one PCMCIA channel, 16-bit sound support, and other options.

This development platform and board support packages are now available. Three technical support credits are included to assist with initialization. The starting price is $4995.

Complete Plug-In Computer Measures Just 2.5 By 4 in.
The CPC-2245 is a fully functional plug-in computer that's about the size of an audio cassette—about 2.5 by 4 in. It's designed to act as a standalone computer in applications where size is a factor, such as portable test equipment and intelligent access controls. Also, it can be used as a plug-in processor or as an integrator's board. It includes a 486-level processor, an 8-kbyte cache and 32 Mbytes of RAM, and a 10/100Base-T Ethernet controller. A PCI slot, a VGA interface with a 64-bit accelerator, two serial ports, a parallel or floppy disk port, support for up to two hard drives, and other interfaces needed to make it a full computer are packed in as well. A CompactFlash is provided for a solid-state disk. Windows CE can be pre-installed. A DIMM connector along one edge lets the device plug into larger application-specific boards. Available now, the CPC-2245 costs under $400 in evaluation quantities.
