54 / 136 page ![]() MPC5643L Microcontroller Data Sheet, Rev. 10 Package pinouts and signal descriptions NXP Semiconductors 54 2.3 System pins NOTE None of system pins (except RESET) provides an open drain output. 2 VSS_LV balls are tied together on the 257 MAPBGA substrate. 3 VDD_HV balls are tied together on the 257 MAPBGA substrate. 4 VSS_HV balls are tied together on the 257 MAPBGA substrate. Table 6. System pins Symbol Description Direction Pin # 144 pkg 257 pkg Dedicated pins MDO01 1 This pad is configured for Fast (F) pad speed. Nexus Message Data Output — line Output only 9 E1 NMI2 2 This pad contains a weak pull-up. Non Maskable Interrupt Input only 1 E4 XTAL Input for oscillator amplifier circuit and internal clock generator Input only 29 N1 EXTAL3 3 EXTAL is an "Output" in "crystal" mode, and is an "Input" in "ext clock" mode. Oscillator amplifier output Input/Output4 4 In XOSC Bypass Mode, the analog portion of crystal oscillator (amplifier) is disabled. An external clock can be applied at EXTAL as an input. In XOSC Normal Mode, EXTAL is an output 30 R1 TMS2 JTAG state machine control Input only 87 M16 TCK2 JTAG clock Input only 88 L15 JCOMP5 5 This pad contains a weak pull-down. JTAG compliance select Input only 123 C10 Reset pin RESET Bidirectional reset with Schmitt-Trigger characteristics and noise filter. This pin has medium drive strength. Output drive is open drain and must be terminated by an external resistor of value 1KOhm.6 6 RESET output shall be considered valid only after the 3.3V supply reaches its stable value. Bidirectional 31 P2 Test pin VPP TEST Pin for testing purpose only. To be tied to ground in normal operating mode. 107 D15 |
