7 / 138 page Introduction 7 December 2004 − Revised September 2006 SGUS053B 2.4 Signal Descriptions Table 2−2 specifies the signals on the F2812 device. All digital inputs are TTL-compatible. All outputs are 3.3 V with CMOS levels. Inputs are not 5-V tolerant. A 100- µA (or 20-µA) pullup/pulldown is used. Table 2−2. Signal Descriptions† NAME PIN NO. I/O/Z‡ PU/PD§ DESCRIPTION NAME 172-PIN HFG I/O/Z‡ PU/PD§ DESCRIPTION XINTF SIGNALS XA[18] 154 O/Z − XA[17] 152 O/Z − XA[16] 149 O/Z − XA[15] 145 O/Z − XA[14] 141 O/Z − XA[13] 138 O/Z − XA[12] 135 O/Z − XA[11] 129 O/Z XA[10] 127 O/Z − XA[9] 122 O/Z − 19-bit XINTF Address Bus XA[8] 118 O/Z − 19-bit XINTF Address Bus XA[7] 116 O/Z − XA[6] 109 O/Z − XA[5] 106 O/Z − XA[4] 101 O/Z − XA[3] 83 O/Z − XA[2] 78 O/Z − XA[1] 42 O/Z − XA[0] 18 O/Z XD[15] 144 I/O/Z PU XD[14] 136 I/O/Z PU XD[13] 95 I/O/Z PU XD[12] 94 I/O/Z PU XD[11] 72 I/O/Z PU XD[10] 71 I/O/Z PU XD[9] 67 I/O/Z PU XD[8] 64 I/O/Z PU 16-bit XINTF Data Bus XD[7] 53 I/O/Z PU 16-bit XINTF Data Bus XD[6] 38 I/O/Z PU XD[5] 35 I/O/Z PU XD[4] 32 I/O/Z PU XD[3] 29 I/O/Z PU XD[2] 26 I/O/Z PU XD[1] 23 I/O/Z PU XD[0] 20 I/O/Z PU † Typical drive strength of the output buffer for all pins is 4 mA except for TDO, XCLKOUT, XF, XINTF, EMU0, and EMU1 pins, which are 8 mA. ‡ I = Input, O = Output, Z = High impedance § PU = pin has internal pullup; PD = pin has internal pulldown |
