8/07/96 - 3-Pin Processor Supervisor Incorporates Watchdog Timer
TEXT
MOUNTAIN VIEW, CALIF. (Aug. 7) BUSINESS WIRE -Aug. 7, 1996--TelCom Semiconductor Inc. (NASDAQ:TLCM
) today announced the industry"s first processor supervisor to incorporate a power supply monitor, reset generator (with
external override) and watchdog timer in a 3-pin package.
Now available in a TO-92 package, and soon to be released in a SOT-223 package, the TC32M offers the same functionality
as the industry standard, TC1232, but in a smaller, lower cost configuration.
The TC32M maintains the processor in the reset state whenever supply voltage is out-of-tolerance. Once the supply is within
tolerance, the TC32M maintains the processor in reset for an additional 250mS to allow time for the system to stabilize. During
normal system operation, the processor must apply pulses to the TC32M at a prescribed rate.
Should the processor fail to do this, a system fault is indicated, and the TC32M issues a momentary processor reset as a result.
The output of the TC32M may be wire-ORed with an external auxiliary reset signal or push-button switch for reset override
control.
The TC32M is ideal for applications which require a fully-integrated processor supervisor such as battery-powered computers
and controllers, automotive instruments, embedded controllers, and critical microprocessor power monitoring.
The TC32M is available with an operating temperature range of 0 degree C to +70 degrees C or -40 degrees C to +85
degrees C. The TC32M will be available in a SOT-223 package in the fourth quarter of 1996. Ten thousand piece pricing for
the TO-92 package is $0.60 and $0.65, respectively. Ten thousand piece pricing for the SOT-223 package is $0.68 and
$0.72, respectively.
TelCom Semiconductor is a high performance analog company that develops, manufactures and markets integrated circuits for
a broad spectrum of customers with commercial, high-volume, product applications. TelCom"s product direction focuses on
