9 / 67 page  TMS470R1VF48C/VF48B 16/32-BIT RISC FLASH MICROCONTROLLERS SPNS093D – MAY 2004 – REVISED FEBRUARY 2006 9 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251-1443 Terminal Functions 1 PWR = power, GND = ground, REF = reference voltage, NC = no connect 2 All I/O pins, except RST, are configured as inputs while PORRST is low and immediately after PORRST goes high. 3 IPD = internal pulldown, IPU = internal pullup (all internal pullups and pulldowns are active on input pins, independent of the PORRST state.) TERMINAL INPUT VOLT- AGE(1)(2) OUTPUT CURRENT(1)(2) INTERNAL PULLUP/ PULL- DOWN(3) DESCRIPTION NAME PIN NO. HIGH-END TIMER (HET) HET[0] 73 3.3-V 2mA -z IPD (20 μA) Timer input capture or output compare. The HET[8:0,18,20,22] applicable pins can be programmed as general-purpose input/output (GIO) pins. All are high-resolution pins. The high-resolution (HR) SHARE feature allows even HR pins to share the next higher odd HR pin structures. This HR sharing is independent of whether or not the odd pin is available externally. If an odd pin is available externally and shared, then the odd pin can only be used as a general- purpose I/O. For more information on HR SHARE, see the TMS470R1x High-End Timer (HET) Reference Guide (literature number SPNU199). HET[1] 72 HET[2] 71 HET[3] 66 HET[4] 65 HET[5] 63 HET[6] 9 HET[7] 11 HET[8] 12 HET[18] 15 HET[20] 18 HET[22] 19 HIGH-END CAN CONTROLLER (HECC) CAN1HRX 83 5V tolerant 4mA HECC1 receive pin or GIO pin CAN1HTX 84 3.3-V 2mA -z IPU (20 μA) HECC1 transmit pin or GIO pin CAN2HRX 54 5V tolerant 4mA HECC2 receive pin or GIO pin CAN2HTX 55 3.3-V 2mA -z IPU (20 μA) HECC2 transmit pin or GIO pin STANDARD CAN CONTROLLER (SCC) CANSRX - 5V tolerant 4mA SCC receive pin.The CANSRX signal is only connected to the pad and not to a package pin. For reduced power consumption in low power mode, CANSRX should be driven output LOW. CANSTX - 3.3-V 2mA -z IPU (20 μA) SCC transmit pin. The CANSTX signal is only connected to the pad and not to a package pin. For reduced power consumption in low power mode, CANSTX should be driven output LOW. GENERAL-PURPOSE I/O (GIO) GIOA[0]/INT[0] 141 5V tolerant 4mA General-purpose input/output pins. GIOA[7:0]/INT[7:0] are interrupt- capable pins. GIOA[1]/INT[1]/ECLK pin is multiplexed with the external clock-out function of the external clock prescale (ECP) module. GIOA[1]/INT[1]/ ECLK 136 GIOA[2]/INT[2] 134 GIOA[3]/INT[3] 133 GIOA[4]/INT[4] 127 GIOA[5]/INT[5] 98 GIOA[6]/INT[6] 78 GIOA[7]/INT[7] 79 GIOB[0] 43 3.3-V 2mA -z IPD (20 μA) GIOB[0], GIOC[4:0], GIOD[5:0], GIOE[7:0:], GIOF[7:0], GIOG[7:0], AND GIOH[5,0] are multiplexed with the expansion bus module. SeeTable 6. GIOC[0] 135 GIOC[1] 128 GIOC[2] 126 GIOC[3] 120 GIOC[4] 119 |
