S-35192A - 3-WIRE REAL-TIME CLOCK

Seiko Instruments Inc 2008/10/08 09:26

General Description
The S-35192A is a CMOS 3-wire real-time clock IC which operates with the very low current
consumption and in the wide range of operation voltage. The operation voltage is 1.3 V to 5.5
V so that this IC can be used for various power supplies from main supply to backup battery.
Due to the 0.45 μA current consumption and wide range of power supply voltage at time keeping, this IC makes the battery life longer. In the system which operates with a backup
battery, the included free registers can be used as the function for user’s backup memory.
Users always can take back the information in the registers which is stored before power-off
the main power supply, after the voltage is restored.
This IC has the function to correct advance/delay of the clock data speed, in the wide range,
which is caused by the oscillation circuit’s frequency deviation. Correcting according to the
temperature change by combining this function and a temperature sensor, it is possible to
make a high precise clock function which is not affected by the ambient temperature.

Features
*Low current consumption : 0.45 μA typ. (VDD = 3.0 V, Ta = 25°C)
*Constant output of 32.768 kHz clock pulse (Nch open-drain output)
*Wide range of operating voltage : 1.3 to 5.5 V
*Built-in clock-correction function
*Built-in free user register
*3-wire (MICROWIRE) CPU interface
*Built-in alarm function
*Built-in flag generator during detection of low power voltage or at power-on
*Auto calendar up to the year 2099, automatic leap year calculation function
*Built-in constant voltage circuit
*Built-in 32.768 kHz crystal oscillator (Cd built in, Cg external)
*Package : SNT-8A
*Lead-free product

Applications
*Mobile game devices
*Mobile AV devices
*Digital still cameras
*Digital video cameras
*Electronic power meters
*DVD recorders
*TVs, VCRs
*Mobile phones, PHS
*Car navigation

PE4302 - 50 Ω RF Digital Attenuator 6-bit, 31.5 dB, DC – 4.0 GHz

Peregrine Semiconductor 2008/10/08 09:17

Product Description
The PE4302 is a high linearity, 6-bit RF Digital Step Attenuator (DSA) covering a 31.5 dB attenuation range in 0.5 dB steps. This 50-ohm RF DSA provides both parallel and serial CMOS
control interface operates on a single 3-volt supply and maintains high attenuation accuracy over frequency and temperature. It also has a unique control interface that allows the user to select an initial attenuation state at power-up. The PE4302 exhibits very low insertion loss and low power consumption. This functionality is delivered in a 4x4 mm QFN footprint.
The PE4302 is manufactured on Peregrine’s UltraCMOS™ process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate, offering the performance of GaAs with the economy and integration of conventional CMOS.

Features
*Attenuation: 0.5 dB steps to 31.5 dB
*Flexible parallel and serial programming interfaces
*Unique power-up state selection
*Positive CMOS control logic
*High attenuation accuracy and linearity over temperature and frequency
*Very low power consumption
*Single-supply operation
*50 Ω impedance
*Packaged in a 20 lead 4x4mm QFN
