Description
1 to 8
D7 to D0
8-Bit Bidirectional Parallel Programming Data Inputs. Used only in parallel programming mode.
9, 10, 23, 24, 25,
73, 74, 79, 80
DVDD
Connections for the Digital Circuitry Supply Voltage. Nominally 3.3 V more positive than AGND
and DGND.
11, 12, 26, 27, 28,
72, 75 to 78
DGND
Connections for the Digital Circuitry Ground Return. Same potential as AGND.
13, 35, 57, 58, 63
NC
No Internal Connection.
14 to 16
A5 to A3
Parallel Address Inputs for Program Registers (Part of 6-Bit Parallel Address Inputs for Program
Register, A5:A0). Used only in parallel programming mode.
17
A2/IO RESET
Parallel Address Input for Program Registers (Part of 6-Bit Parallel Address Inputs for Program
Register, A5:A0)/IO Reset. A2 is used only in parallel programming mode. IO RESET is used when
the serial programming mode is selected, allowing an IO RESET of the serial communication bus
that is unresponsive due to improper programming protocol. Resetting the serial bus in this
manner does not affect previous programming, nor does it invoke the default programming
values listed in Table 8. Active high.
18
A1/SDO
Parallel Address Input for Program Registers (Part of 6-Bit Parallel Address Inputs for Program
Register, A5:A0)/Unidirectional Serial Data Output. A1 is used only in parallel programming
mode. SDO is used in 3-wire serial communication mode when the serial programming mode is
selected.
19
A0/SDIO
Parallel Address Input for Program Registers (Part of 6-Bit Parallel Address Inputs for Program
Register, A5:A0)/Bidirectional Serial Data I/O. A0 is used only in parallel programming mode. SDIO
is used in 2-wire serial communication mode.
