The pin of CPU described in the present embodiment has diode or resolution element to be connected to Vcc.If the voltage mistake of access
Height, then electric current power supply will be flowed to by diode or resolution element.Such as plus 5V's on the input of 3.3V devices
Signal, then 5V power supplys can be to 3.3V power source charges.Lasting electric current will damage diode and other circuit elements.Two power supplys
Between electric current mutual string problem.In wait or power-down mode, 3.3V power supplys drop to 0V, and high current will be passed to ground, and this makes
Obtain the high voltage in bus and pulled down to ground, these situations will cause loss of data and component wear.It should be noted that:No matter
Still current direction Vcc interfaces are not allowed to input switching threshold problem in 0V wait state in 3.3V working condition.With
5V device drives the 3.3V device to have many different situations, and there is also not for the switching levels between same TTL and CMOS
Same situation.Driver must is fulfilled for the input switching levels of receiver, and to have enough tolerance limits to ensure not damage circuit
Element.
The representative value of 5V cmos devices output is 3.6V.Therefore, if 3.3V devices can bear 5V voltage, from
It can be joined directly together completely on level.But because activation configuration can be different, therefore we are in design
Technical controlling is carried out to the voltage for being added to MSP430 inputs, it is no more than 3.6V, makes provision against emergencies because 3.3V and 5V CMOS
Level conversion standard is the same, therefore does not need extra device can be joined directly together the two.Extra electricity is not needed
Road is directly from MSP430 drivings 5V device, it appears that is mysterious, but VOH the and VOL level of 3.3V devices is divided
Not, VIH the and VIL level of 2.4V and 0.4V, 5V cmos device is 2V and 0.8V respectively.And MSP430 can actually export 3V
The voltage of the amplitude of oscillation, although 5V cmos devices can correctly identify MSP430 incoming level；MSP430 and the 4 of 5V electric level interfaces
Kind situation 5VTTL device drives MSP430.
Obviously, 5V TTL and 3.3V switching levels are different.But 5V TTL VOH and VOL and 3.3V
Although VIH and VIL switching levels, which can be seen that both, has certain difference, the 3.3V devices of 5V voltages can be born
Part can correctly identify the level value that 5V devices are sent.So the input that can bear the 3.3V devices of 5V voltages can be direct
With the output end interface of 5V devices.Because MSP430 does not have 5V tolerance limits, it is impossible to directly with the output end interface of 5V devices；It is 3.3V defeated
The high-tension minimum voltage value VOH 2.4V (ceiling voltage of output can reach 3.3V) gone out, and the requirement of 5V cmos devices
High level minimum voltage VIH 3.5V, therefore the input that MSP430 output can not be directly with 5VCMOS devices is connected.Institute
So that when 5V cmos devices driving MSP430 or MSP430 is with 5V TTL device interfaces, the two can not be joined directly together.Level
Circuit design is the mutual conversion by 3.3V and 5V level.Supplied using twin voltage (while being 3.3V, another side is 5V)
The bidirectional drive of electricity realizes level conversion.Such as TI SN74ALVC164245, SN74ALVC4245 chip, is preferably solved
Determine the transfer problem of 3.3V and 5V level.In the case of when 5V TTL drive MSP430, we are simply done using one
Method is exactly electric resistance partial pressure.MSP430MSP430 Series of MCU all carries serial communication port, has several moneys to also have two serial ports.This
Sample just facilitate with PC interface, enhance the ability of communication with the outside world.
It is greatly that (PIC's can be connected directly between computer string using Transistor-Transistor Logic level standard that the serial ports of single-chip microcomputer, which has,
Mouthful), its level of logic 1 is 5V, and logical zero level is 0V, and used in computer serial port is RS232C level standard, it
The level of logic 1 be -3V--12V, logical zero level is+3V-+12V.Both level ranges fall far short, so being needed during connection
Use level shifting circuit.So circuit has a lot of kinds, and in general commercialized finished product can use MAX232, DS275 etc.
Special RS232, Transistor-Transistor Logic level converter ic, are come less for ordinary electronic fan using such device one
Good purchase, two improve the expense of making, and that is gone to replace them with which type of circuitThis is also that I just makes monolithic
One of the problem of encountered in the application of machine combination computer, some related circuit data were have found later, these is solved and asks
