TERMINAL TYPE†‡ INTERNAL PULLUP/ PULLDOWN§ DESCRIPTION NAME VC338X VC348X GENERAL-PURPOSE I/O (GIO) GIOA[0]/INT0 28 28 3.3-V I IPD General-purpose input/output pins. GIOA[0]/INT[0] is an input-only pin. 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[2]/INT[2] and GIOA[3]/INT[3] pins are not applicable on the VC338x device. GIOA[1]/INT1/ ECLK 29 29 3.3-V I/O GIOA[2]/INT2 – 30 GIOA[3]/INT3 – 31 GIOA[4]/INT4 25 25 GIOA[5]/INT5 24 24 GIOA[6]/INT6 23 23 GIOA[7]/INT7 22 22 GIOB[0] – 16 3.3-V I/O IPD General-purpose input/output pins (VC348x only). GIOB[1] – 15 GIOB[2] – 14 GIOB[3] – 13 MULTI-BUFFERED ANALOG-TO-DIGITAL CONVERTER (MibADC) ADEVT 67 66 3.3-V I/O IPD MibADC event input. ADEVT can be programmed as a GIO pin.The ADEVT pin can also be used as a user-selectable event source to "event trigger" the MibADC event group or group1 providing the associated register source bits are properly configured and defined. For the internal device connections, see the MibADC section of this data sheet. ADIN[0] 75 75 3.3-V I MibADC analog input pins The VC338x device has only 12 input channels but all S/W registers are capable. ADIN[15:12] pins are not applicable to the VC338 device. The VC348x device has all 16 input channels. ADIN[1] 74 74 ADIN[2] 73 73 ADIN[3] 72 72 ADIN[4] 71 71 ADIN[5] 70 69 ADIN[6] 69 68 ADIN[7] 68 67 ADIN[8] 79 82 ADIN[9] 78 80 ADIN[10] 77 78 ADIN[11] 76 76 ADIN[12] – 81 ADIN[13] – 79 ADIN[14] – 77 ADIN[15] – 70 ADREFHI 80 83 3.3-V REF I MibADC module high-voltage reference input ADREFLO 81 84 GND REF I MibADC module low-voltage reference input VCCAD 82 85 3.3-V PWR MibADC analog supply voltage VSSAD 83 86 GND MibADC analog ground reference |
