Lattice Semiconductor has announced the completion of the production release of its second-generation SuperFAST BFW (Big-Fast-Wide) family, the ispLSI 2000VE family.
Analogue front end is dynamically reconfigurable
Lattice Semiconductor has added a new member to its ispPAC programmable analogue device family.
This in-system programmable (ISP) logic family, which provides up to double the logic capacity of Lattice's popular ispLSI 5000VE devices, includes new features such as advanced I/O standard (GTL+, HSTL, SSTL etc) sysIO support and sysCLOCK phase locked loops (PLLs).
Performance for the ispMACH 5768VG is specified at 5ns pin-to-pin logic delays (tPD) with an operating frequency (fMAX) of 178MHz - world-class performance for a device of this density.
The release of this family represents the completion of Lattice's second generation of BFW (big-fast-wide) products, consisting of the 3.3V ispMACH 5000VG, ispLSI 2000VE and ispLSI 5000VE families.

Lattice Semiconductor has added to its ispPAC programmable analogue device family with the ispPAC81 in-system programmable continuous time filter.
"The ispMACH 5000VG family delivers CPLD performance and predictability while supporting logic densities and system integration capabilities previously only available in FPGAs", said Steve Stark, Director of Product Marketing at Lattice.
"System designers now have a powerful new CPLD family to implement their next generation logic designs".
The devices from the ispMACH 5000VG family incorporate a SuperWIDE macrocell architecture pioneered in Lattice's ispLSI 5000V family.
Logic capacities beginning at 768 macrocells are large enough to hold multiple functions commonly implemented in CPLDs such as bus bridges, memory controllers, and control logic, and far exceed the 512 macrocell maximum typically found with competitive CPLDs.
The large number of sysIO-capable pins (from 196 to 384 per device) provided in the ispMACH 5000VG devices makes them ideal for wide bus interface applications.
The instant power-up capability of these devices makes them suitable for power-up sequence control in large, complex systems.
Each I/O pin on the ispMACH 5000VG devices can be configured to support high-speed memory interfaces, advanced bus standards, or general-purpose interfaces.
General-purpose interface support includes LVTTL or LVCMOS (3.3, 2.5 and 1.8V).
The LVTTL and LVCMOS 3.3 interfaces are 5V tolerant, supporting easy integration into legacy designs.
Programmable drive levels for these standards facilitate the elimination of series termination resistors, reducing overall system cost.
Interface to high speed DRAMs, SRAMs, and other high performance memory devices is made possible with SSTL2, SSTL3, and HSTL I/O support.
The ispMACH 5000VG family also supports GTL+, PCI, and PCI-X I/O configurations for use in high-speed bus interfaces.
The ispMACH 5000VG devices have two sysCLOCK PLLs that provide precise timing control for today's high-speed designs.
Designers can generate complex clock waveforms with the clock multiply and divide capability of the PLL as well as adjust setup, hold and clock to output timings by shifting the clock under sysCLOCK control.
This family uses the proven SuperWIDE 68-input logic block that is found in other ispLSI 5000V devices, providing excellent support for emerging 64bit applications.
This SuperWIDE capability can lead to a 60% performance gain compared to devices with the more traditional 36-input logic block for complex logic functions.
Additionally, Lattice has enhanced the ispMACH 5000VG logic block by increasing the maximum number of product terms per function from the 35 implemented in the ispLSI 5000VE series to 160.
This leads to further performance improvements, up to 25% faster than architectures that support a maximum of 35 product terms per function.
The ispMACH 5000VG family is supported by Lattice's new ispLEVER Version 1.0 design tools available today from Lattice.
The ispLEVER tools, Lattice's platform for next-generation logic design, provide designers with rapid access to the performance and features of the ispMACH 5000VG devices while maximising resource utilisation.
This is achieved through timing driven placement and routing coupled with optimised synthesis support from vendors such as Exemplar and Synplicity.
Lattice customers with valid software maintenance agreements will be upgraded to the new software suite during the first quarter of 2002.
The ispMACH 5768VG is available now in 256- and 484-ball fine pitch BGA packaging featuring a space-saving 1mm ball pitch.
Projected pricing for the ispMACH 5768VG is as low as $33.00 in high-volume for the second half of 2002.
