San
Jose, CA -- June 15 2004 --
Summit Microelectronics has
announced availability of the
SMS45
and
SMS47
programmable voltage supervisors
with four channels of precision
monitoring and three channels of
programmable cascaded
sequencing
Precision monitoring is provided
at a resolution of 5mV on four
separate, user-programmable
voltages without the need for any
external voltage divider
circuitry. This feature differs
from other market offerings which
require factory-trimmed threshold
voltages and external components
to accommodate different supply
voltages and tolerances.
Each device utilizes four
independent nonvolatile DACs for
user programming of the over
voltage and under voltage set
points on the monitored
channels.
Both the SMS45 and SMS47 can be
accessed by the popular I2C bus
to exercise complete control of
the device's characteristics.
This can be done during
production, or each time that the
board is booted up, or during
normal operation "on the
fly."
Applications include
datacomm/netcomm and
storage/computing as well as
consumer products.
DESIGN SOFTWARE AND PROGRAMMER
FOR PROTOTYPE DEVELOPMENT
To speed user product
development using the SMS45 and
SMS47, Summit offers customers
the SMX3200
programming
system.
This is a complete development
tool that lets designers easily
manipulate the characteristics of
their system. The SMX3200 design
kit includes menu-driven
Microsoft Windows" graphic user
interface (GUI) software to
automate programming tasks and
also includes all necessary
hardware to interface to the
parallel port of a laptop or PC.
This system has seen widespread
acceptance by users since it was
introduced four years ago.
Once a user completes design and
prototyping, SMX3200
automatically generates a HEX
data file that can be transmitted
to Summit for review and
approval. Summit then assigns a
unique customer identification
code to the HEX file and programs
the customer's production devices
prior to final electrical test
operations. This ensures that the
device will operate properly in
the end application. The design
kit software can be downloaded
today from Summit's website
(www.summitmicro.com).
DESIGN KIT FOR AUTOMATED
PROTOTYPE DEVELOPMENT
An evaluation card containing the
SMS45 or SMS47 controller, all
required associated circuitry,
and a port for "plug and play"
programming via the SMX3200
dongle interface is
available.
PRICING AND
AVAILABILITY
Available in volume quantities
today, the SMS45 and SMS47 come
in a 16-lead SSOP package. The
SMS45, with 4 kilobits of user
memory, is priced at $2.25 in
10,000 unit quantities in
commercial temperature range. The
SMS47, without user memory, is
priced at $1.63 in 10,000 unit
quantities in commercial
temperature range.
