Xicor Announces I2C CPU Supervisors; New Products Expand Xicor's Broad Line of Field Programmable System Management Products.
MILPITAS, Calif.--(BUSINESS WIRE)--June 1, 1999--
XICOR, Inc., today announced I2C I2C Inter-Integrated Circuit
I2C Intelligent Interface Controller
I2C Intelligent Controller versions of its CPU CPU
in full central processing unit
Principal component of a digital computer, composed of a control unit, an instruction-decoding unit, and an arithmetic-logic unit. supervisor products.
The X4043 and X4045 integrate power-on-reset, watchdog timer A clock circuit that keeps counting from a set number down to zero. If the event it is monitoring occurs before it reaches zero, it resets to the starting number and starts counting down again. and low voltage Low voltage is an electrical engineering term that broadly identifies safety considerations of an electricity supply system based on the voltage used. While different definitions exist for the exact voltage range covered by "low voltage", the most commonly used ones include "mains sense functions with 4K of EE memory on a single device. The devices also include the industry standard 400K Hz I2C serial interface. The X4003 and X4005 have the same feature set at the X4043 and X4045 respectively, except for the memory.
The primary advantage of these products is that the low voltage reset levels and watchdog timer intervals can be reprogrammed in the field thus eliminating the inflexibility of a fixed device.
The X4003 and X4043 products implement active low RESET. The X4005 and X4045 implement active high RESET.
The watchdog timer can be programmed by the user to timeout intervals ranging from 200 milliseconds to 1.4 seconds. Additionally, it can be disabled to facilitate system software debugging (programming) debugging - The process of attempting to determine the cause of the symptoms of malfunctions in a program or other system. These symptoms may be detected during testing or use by real users. . The low voltage reset trip points can be programmed from 1.7 to 4.75 volts, with an accuracy of 25 millivolts. Low voltage reset thresholds can be reprogrammed, should system requirements To be used efficiently, all computer software needs certain hardware components or other software resources to be present on a computer system. These pre-requisites are known as (computer) system requirements and are often used as a guideline as opposed to an absolute rule. change.
These four I2C products are part of Xicor's expanding system management product line that includes the X5000 family of SPI (1) (Stateful Packet Inspection) See stateful inspection.
(2) (Service Provider Interface) The programming interface for developing Windows drivers under WOSA. CPU supervisors, and the X1200 family of real time clocks. All are ideal for demanding embedded control applications where systems must power up in known state and power down in an orderly manner in the event of unforeseen external events.
"These functions are used by all embedded system Any electronic system that uses a CPU chip, but that is not a general-purpose workstation, desktop or laptop computer. Such systems generally use microprocessors, or they may use custom-designed chips or both. designers," said Wayne Eng, director of digital products marketing. "Our solution offers increased functionality and flexibility.
"By enabling the designer to program in-the-system key parameters such as watchdog timer reset intervals, and low voltage trip points, we provide the maximum flexibility to tune device parameters for the most exacting system requirements. If the system design parameters change, the designer can easily reprogram re·pro·gram
