PC0062 Datasheet
PC0062 Price In the low data rate mode, the PWIDTH pin sets the width of the ON pulse tPWi to RFAl with a resistor to ground (the ON pulse width tPW2 to RFA2 is set at l.1 times the pulse width to RFAl in the low data rate mode). The ON pulse width tPWl can be adjusted between 0.55 and l ps. However, when the PWIDTH pin is connected to Vcc through a l M resistor, the RF amplifiers operate at a nominal 50%-50% duty cycle, facilitating high data rate operation. In this case, the RF amplifiers are controlled by the PRATE resistor as de- scribed above. PC0062 on stock SHARP'S LH28F008SA 8M Flash FileTM Memory is the highest density nonvolatile read/write solution for solid state storage. The LH28F008SA's extended cycling, symmetrically blocked architecture, fast access time, write automation and low power consumption pro- vide a more reliable, lower power, lighter weight and higher pertormance alternative to traditional rotating disk technology. The LH28F008SA brings new capabilities to portable computing. Application and operating sys- tem software stored in resident flash memory arrays provide instant-on rapid execute-in-place and protec- tion from obsolescence through in-system software updates. Resident software also extends system bat- tery life and increases relaibility by reducing disk drive accesses. The MAX6690 is a temperature sensor that communi- cates through an SMBus/12C-compatible interface with a UP in thermal-management applications. Essentially an ll~bit serial analog-to-digital converter (ADC) with a sophisticated front end, the MAX6690 measures the change in diode voltage at different current levels to cal- culate temperature. It contains a current source, a multi- plexer, an ADC, an SMBus interface, and associated control logic (Figure l). Temperature data from the ADC is loaded into data registers, where it is automatically compared with data previously stored in four over/undertemperature alarm registers. |
