DEVICE DESCRIPTION
The TRAC family of Field Programmable
Analog Devices offers an integrated path from
signal processing problems to working silicon
solutions - in minutes!
Reconfigurable Analog Circuit is a highly
flexible single chip solution to the signal
processing problems found in many markets.
Introducing a Top-Down, Structured design
discipline,
implementation, prototyping and product
release. Rather than working at the component
level, TRAC champions the Computational
Approach, providing designers with benefits
formerly associated only with programmable
digital devices. TRAC brings a truly integrated
Signal Processing problem solving process,
offering a path to Custom Silicon for higher
volume users.
TRAC devices have to be loaded with program
data at power-up and run from a split 5V
supply. By integrating the loading interface
circuitry, voltage regulation, supply
monitoring and thermal protection, the TRAC
support circuit (TRAC-S2) further simplifies
circuit integration and interface with memory
devices.
An adjustable frequency oscillator clocks
program data out of a serial output memory
device and into any number of cascaded TRAC
devices. By monitoring the bit stream pattern,
TRAC-S2 can sense when loading is complete
and stop clocking automatically.
An adjustable ‘rail-splitter’ generates the
ground supply rail, and the supply monitoring
function initiates program load on power-up,
and after power failure or serious fluctuation.
Thermal shutdown further protects the device
against overheating.
