2 / 40 page  MT89L86 Advance Information 2 Figure 2 - Pin Connections Pin Description Pin # Name Description 44 PLCC 48 SSOP 22 DTA Data Acknowledgment (Open Drain Output). This active low output indicates that a data bus transfer is complete. A pull-up resistor is required at this output. 3-5 7-9 3-5 7-9 STi0-5 ST-BUS Inputs 0 to 5 (5V-tolerant Inputs). Serial data input streams. These streams may have data rates of 2.048, 4.096 or 8.192 Mbit/s with 32, 64 or 128 channels, respectively. 10 10 STi6/A6 ST-BUS Input 6/Addr.6 input (5V-tolerant Input). The function of this pin is determined by the switching configuration enabled. If non-multiplexed CPU bus is used along with a higher input rate of 8.192 or 4.096 Mb/s, this pin provides A6 address input function. For 2.048 and 4.096 Mb/s (8x4) applications or when the multiplexed CPU bus interface is selected, this pin assumes STi6 function. See Control Register bits description and Tables 1, 2, 6 & 7 for more details. Note that for applications where both A6 and STi6 inputs are required simultaneously (e.g., 8 x 4 switching configuration at 4.096 Mb/s or rate conversion between 2.048Mb/ s to 4.196 or 8.192 Mb/s) the A6 input should be connected to pin STo6/A6. 11 11 STi7/A7 ST-BUS Input 7/Addr.7 input (5V-tolerant Input): The function of this pin is determined by the switching configuration enabled. If non-multiplexed CPU bus is used along with a higher input rate of 8.192 Mb/s, this pin provides A7 address input function. For 2.048 and 4.096 Mb/s (8x4) applications or when the multiplexed CPU bus is selected, this pin assumes STi7 function. See Control Register bits description and Tables 1, 2, 6 & 7 for more details. Note that for applications where both A7 and STi7 inputs are required simultaneously (e.g., 2.048 to 8.192 Mb/s rate conversion) the A7 input should be connected to pin STo7/A7. 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 1 48 PIN SSOP 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 ODE STo0 STo1 STo2 STi14/STo8 STo3 STo4 STo5 STo6/A6 STo7/A7 VSS VDD AD0 AD1 AD2 AD3 AD4 STi15/STo9 AD5 AD6 DTA STi0 STi1 STi2 AS/ALE STi3 STi4 STi5 STi6/A6 STi7/A7 VDD RESET FR CLK STi8/A0 STi9/A1 STi10/A2 IM STi11/A3 STi12/A4 1 6 5 4 3 2 44 43 42 41 40 7 8 9 10 11 12 13 14 15 16 39 38 37 36 35 34 33 32 31 30 23 18 19 20 21 22 24 25 26 27 28 17 29 STo3 STo4 STo5 STo6/A6 STo7/A7 VSS AD0 AD1 AD2 AD3 AD4 STi3 STi4 STi5 STi6/A6 STi7/A7 VDD FR CLK STi8/A0 STi9/A1 STi10/A2 44 PIN PLCC 48 CSTo VSS 21 27 AD7 STi13/A5 22 26 CS DS/RD 23 25 VSS R/W\WR 24 (JEDEC MO-118, 300mil Wide) |
