TOTALLY RE-CONFIGURABLE ANALOG
CIRCUIT - TRAC®
Issue 2 - MARCH 1999
TRAC020LH
DEVICE DESCRIPTION
The TRAC020LH is a Micro-Power version of
the existing TRAC products. It also offers
significant improvements in bandwidth and
function accuracy.
The TRAC020LH is the latest addition to the
TRAC family of Field Programmable Analog
Devices (FPAD) which offers an integrated path
from signal processing problems to working
silicon solutions - in minutes! The Totally
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, TRAC enables rapid
implementation, prototyping and product
release. Rather than working at the component
level, TRAC champions the Computational
Approach, providing designers with benefits
formerly associated with programmable
digital devices. TRAC brings a truly integrated
Signal Processing problem solving process
and offers a path to Custom Silicon for high
volume applications.
APPLICATIONS

• Complete more projects on time
• High level of integration and design secrecy
• Integration with other CAE systems
• Transparent design migration to
semi-custom and future devices
• Less than 8 bytes to program
• Full industrial temperature range
• Standby mode for improved battery life
• Devices easily cascaded for more complex
designs
• Combines silicon, software and support

DESCRIPTION OF PIN FUNCTIONS
DATA
Serial programming data is input to the TRAC via this pin. Each TRAC cell contains
a 3-bit shift register that allows each cell to be programmed to the required analog
function.
RESET
Active low - The pin resets all on-chip shift registers to the logic zero state, which sets
all TRAC cells to the OFF function. The pin should be held high while the device is
being programmed and when the analog functions are in use.
PD
CLOCK
Active low - The pin switches off the bias generators to the analog cells, which turns
off the supply current to all the TRAC cells. This does not influence the programming
of the cells so this feature can be used to reduce power consumption for applications
that have a standby mode. The pin should be held high while the device is being
programmed and when the analog functions are in use. This pin is permanently held
high (VDD) on the TRAC development board.
Used to clock in the serial data to program the TRAC device. The on-chip shift registers
are positive edge triggered.
DOUT
This pin is the serial data output from cell 20 on the TRAC device. This is used for
validation of programming of the TRAC device. This pin also allows two or more
TRAC devices to be connected in a serial architecture. This is done by connecting the
DOUT pin of the first TRAC device to the DATA pin of the second TRAC device, and
connecting the CLOCK pins.
CLCR
Clock Clear. When the TRAC device is used in stand alone applications CLCR is used
as a control pin. It allows the downloading circuitry to be switched off when the
programming serial data from the EEPROM is complete.
IO3..IO22
These are the analog inputs / outputs for cells 1 to 20.
IO1,IO2
These are the analog inputs for cells 1 and 2.
VDD
AGND
VSS
TRAC positive supply rail (+3V)
Analog Ground
TRAC negative supply rail (-2V) - this will also be the system ground
