Clock chip takes on supervisory functions
Xicor has added two new members to its integrated real time clock (RTC) product family.
Reference design makes for powerful basestations
Xicor has teamed up with Motorola to provide radio-frequency power amplifier (RFPA) reference platforms for GSM, Edge and W-CDMA cellular basestation applications.
The X40626 includes programmable voltage reset trip points for two independent low voltage monitors.
These low voltage monitors can be programmed to detect voltages as low as 2.0V.
User selectable watchdog timeout selection intervals ranging from 250ms to 1.5s can be selected.
The watchdog timer function can be disabled to facilitate system software debugging.
The device also includes embedded EEPROM with Block Lock.
The memory array can be partitioned to protect a quarter, a half or all of the array.
All versions of the product communicate through the industry standard 400kHz two-wire serial interface.
With the introduction of the X40626, Xicor continues to expand its CPU supervisor family of field programmable mixed-signal solutions.
The dual voltage CPU supervisor provides all of the key system management functions that designers need to ensure reliable system operation for applications with multiple voltages.
Supervisory functions are an ideal fit for Xicor's focus on system sensing and control.
These functions are fundamental and used by all embedded system designers.
Particularly, nonvolatile technology provides significant advantages to the designer in terms of flexibility and cost.
According to Intex Management Services Limited (IMS), in 2001, the market for voltage supervision and voltage reference products was $469 million.
This is expected to grow to $674 million in 2005.
This market is driven by a broad range of industrial products and by growth in low power, portable communications products.
