Lattice Semiconductor Introduces ispPAC81 all-in-one Programmable Filter

- In-System Reprogrammable 5th Order Lowpass Filter Operates From 10 kHz to 75 kHz -

HILLSBORO, OR - DECEMBER 3, 2001 - Lattice Semiconductor Corporation (NASDAQ: LSCC), the world's largest supplier of in-system programmable (ISP^TM) devices, today announced the latest member of its ispPAC� programmable analog device family, the ispPAC81 in-system programmable continuous time filter. The ispPAC81 implements tens of thousands of 5th order lowpass filters with corner frequencies ranging from 10 kHz to 75 kHz.

The ispPAC81device is an in-system programmable, precision, all-in-one, continuous-time fifth-order low pass filter. This device can implement filters in Butterworth, Chebychev, Elliptical, and other topologies. It is a sequel to Lattice Semiconductor's award-winning ispPAC80 device. The ispPAC80 addresses 50 kHz to 750 kHz needs, while the new ispPAC81 device extends that range downwards to 10 kHz.

"The task of implementing higher-order filters gets more complicated as the frequency of operation is reduced," said Andy Robin, VP of New Venture Business for Lattice. "Engineers need to handle larger capacitors and resistors with lower tolerance ratings. The ispPAC81 device offers the user unprecedented accuracy of filter implementation, in a remarkably small PCB area coupled with reduced design time and increased manufacturability."

Applications
In DSP systems, an ispPAC81 device is ideal for implementing anti-alias and reconstruction filters. Systems using this device will be able to operate at a reduced sampling rate and also will be more manufacturable, thus reducing the overall system cost.

The ispPAC81 device's lower frequency range makes it very attractive for use in vibration analysis systems reducing noise and improving dynamic range. The frequency range of the ispPAC81 device is also suited for applications like ultrasonic systems, GPS, radar, systems that use velocity and acceleration transducers, and many others.

ispPAC81 is Supported by PAC-Designer� Version 1.3 Software
The ispPAC81 device is supported by Lattice's popular PAC-Designer version 1.3 software. PAC-Designer software is an intuitive schematic design entry and simulation tool. A new capability introduced in this latest version is manufacturing support library functions. These functions can be used by developers of automated test systems to calibrate the analog parameters of their circuit on the manufacturing line to compensate for other components' tolerances, resulting in higher performance, higher yield, and reduced time and cost.

PAC-Designer Version 1.3 software is available for free download from www.latticesemi.com. A free non-time-limited license can also be obtained at that site.

PAC-System Development Kits
The PACsystem80/81 is a low cost development tool designed to enable the designer to build quick prototypes of their circuit implementation and to measure its performance. The design implemented using the PAC-Designer software is downloaded into the device through the ispDOWNLOAD cable that connects to the PC's parallel port. The PACsystem80/81 is comprised of an evaluation board for both the ispPAC80 and the ispPAC81, an ispDOWNLOAD� cable, ispPAC Handbook, PAC-Designer v1.3 software, and samples of the ispPAC80 and ispPAC81 devices.

Price and Availability
The ispPAC81 device in Industrial temperature grade (-40C to +85C) is priced under $7 per device in thousands. The ispPAC81 device is available in both 16-pin SOIC and 16-pin DIP packages. The ordering part numbers of the devices in these two packages are ispPAC81-01SI and ispPAC81-01PI, respectively.

PACsystem80/81 development kits are available through authorized Lattice distributors or on the Lattice web site at a suggested retail price of $149.
