用来做可变速的循迹小车实验比较好!要求有pwm输出的

这个很多，目前有PWM的8位PIC单片机有289种型号！！！最好你还得有其他要求。289种型号如下：PIC12F1501 PIC12F1822 PIC12F1840 PIC12F615 PIC12F617 PIC12F683 PIC12F752 PIC12HV615 PIC12LF1840T48A PIC16F1503 PIC16F1507 PIC16F1508 PIC16F1509 PIC16F1516 PIC16F1517 PIC16F1518 PIC16F1519 PIC16F1526 PIC16F1527 PIC16F1782 PIC16F1783 PIC16F1784 PIC16F1786 PIC16F1787 PIC16F1823 PIC16F1824 PIC16F1825 PIC16F1826 PIC16F1827 PIC16F1828 PIC16F1829 PIC16F1847 PIC16F1933 PIC16F1934 PIC16F1936 PIC16F1937 PIC16F1938 PIC16F1939 PIC16F1946 PIC16F1947 PIC16F616 PIC16F627A PIC16F628A PIC16F648A PIC16F684 PIC16F685 PIC16F690 PIC16F707 PIC16F716 PIC16F72 PIC16F720 PIC16F721 PIC16F722 PIC16F722A PIC16F723 PIC16F723A PIC16F724 PIC16F726 PIC16F727 PIC16F73 PIC16F737 PIC16F74 PIC16F747 PIC16F76 PIC16F767 PIC16F77 PIC16F777 PIC16F785 PIC16F818 PIC16F819 PIC16F87 PIC16F88 PIC16F882 PIC16F883 PIC16F884 PIC16F886 PIC16F887 PIC16F913 PIC16F914 PIC16F916 PIC16F917 PIC16F946 PIC16HV616 PIC16HV785 PIC16LF722 PIC16LF723 PIC16LF724 PIC16LF726 PIC16LF727 PIC18F1220 PIC18F1320 PIC18F13K22 PIC18F13K50 PIC18F14K22 PIC18F14K50 PIC18F2220 PIC18F2221 PIC18F2320 PIC18F2321 PIC18F2331 PIC18F23K20 PIC18F23K22 PIC18F2410 PIC18F2420 PIC18F2423 PIC18F2431 PIC18F2450 PIC18F2455 PIC18F2458 PIC18F2480 PIC18F24J10 PIC18F24J11 PIC18F24J50 PIC18F24K20 PIC18F24K22 PIC18F2510 PIC18F2515 PIC18F2520 PIC18F2523 PIC18F2525 PIC18F2550 PIC18F2553 PIC18F2580 PIC18F2585 PIC18F25J10 PIC18F25J11 PIC18F25J50 PIC18F25K20 PIC18F25K22 PIC18F25K80 PIC18F2610 PIC18F2620 PIC18F2680 PIC18F2682 PIC18F2685 PIC18F26J11 PIC18F26J13 PIC18F26J50 PIC18F26J53 PIC18F26K20 PIC18F26K22 PIC18F26K80 PIC18F27J13 PIC18F27J53 PIC18F4220 PIC18F4221 PIC18F4320 PIC18F4321 PIC18F4331 PIC18F43K20 PIC18F43K22 PIC18F4410 PIC18F4420 PIC18F4423 PIC18F4431 PIC18F4450 PIC18F4455 PIC18F4458 PIC18F4480 PIC18F44J10 PIC18F44J11 PIC18F44J50 PIC18F44K20 PIC18F44K22 PIC18F4510 PIC18F4515 PIC18F4520 PIC18F4523 PIC18F4525 PIC18F4550 PIC18F4553 PIC18F4580 PIC18F4585 PIC18F45J10 PIC18F45J11 PIC18F45J50 PIC18F45K20 PIC18F45K22 PIC18F45K80 PIC18F4610 PIC18F4620 PIC18F4680 PIC18F4682 PIC18F4685 PIC18F46J11 PIC18F46J13 PIC18F46J50 PIC18F46J53 PIC18F46K20 PIC18F46K22 PIC18F46K80 PIC18F47J13 PIC18F47J53 PIC18F6310 PIC18F6390 PIC18F6393 PIC18F63J11 PIC18F63J90 PIC18F6410 PIC18F6490 PIC18F6493 PIC18F64J11 PIC18F64J90 PIC18F6520 PIC18F6527 PIC18F65J10 PIC18F65J11 PIC18F65J15 PIC18F65J50 PIC18F65J90 PIC18F65K22 PIC18F65K80 PIC18F65K90 PIC18F6622 PIC18F6627 PIC18F6628 PIC18F66J10 PIC18F66J11 PIC18F66J15 PIC18F66J16 PIC18F66J50 PIC18F66J55 PIC18F66J60 PIC18F66J65 PIC18F66J90 PIC18F66J93 PIC18F66K22 PIC18F66K80 PIC18F66K90 PIC18F6722 PIC18F6723 PIC18F67J10 PIC18F67J11 PIC18F67J50 PIC18F67J60 PIC18F67J90 PIC18F67J93 PIC18F67K22 PIC18F67K90 PIC18F8310 PIC18F8390 PIC18F8393 PIC18F83J11 PIC18F83J90 PIC18F8410 PIC18F8490 PIC18F8493 PIC18F84J11 PIC18F84J90 PIC18F8520 PIC18F8527 PIC18F85J10 PIC18F85J11 PIC18F85J15 PIC18F85J50 PIC18F85J90 PIC18F85K22 PIC18F85K90 PIC18F8622 PIC18F8627 PIC18F8628 PIC18F86J10 PIC18F86J11 PIC18F86J15 PIC18F86J16 PIC18F86J50 PIC18F86J55 PIC18F86J60 PIC18F86J65 PIC18F86J72 PIC18F86J90 PIC18F86J93 PIC18F86K22 PIC18F86K22 PIC18F86K90 PIC18F8722 PIC18F8723 PIC18F87J10 PIC18F87J11 PIC18F87J50 PIC18F87J60 PIC18F87J72 PIC18F87J90 PIC18F87J93 PIC18F87K22 PIC18F87K90 PIC18F96J60 PIC18F96J65 PIC18F97J60
