I/O
External memory data bus
: 16-bit data bus; used to connect to external RAM and
program memory
External memory data bus bit 14
: 16-bit data bus; used to connect to external RAM
and program memory
Ground
: 0 V reference
Main I/O power supply
: 2.7 to 5.5 V operating range; main supply for the periphery
in normal operation
Power-down indicator
: a LOW on this pin asserts an XA interrupt intended for use
as a power fail interrupt. Once reset is asserted, either by PWRFAIL or the firmware, it
will remain asserted until a set time after this pin goes HIGH.
External memory data bus bit 13
: 16-bit data bus; used to connect to external RAM
and program memory
External memory data bus bit 12
: 16-bit data bus; used to connect to external RAM
and program memory
External memory data bus bit 11
: 16-bit data bus; used to connect to external RAM
and program memory
External memory data bus bit 10
: 16-bit data bus; used to connect to external RAM
and program memory
External memory data bus bit 9
: 16-bit data bus; used to connect to external RAM
and program memory
External memory data bus bit 8
: 16-bit data bus; used to connect to external RAM
and program memory
External memory data bus bit 7
: 16-bit data bus; used to connect to external RAM
and program memory
Ground
: 0 V reference
Main I/O power supply
: 2.7 to 5.5 V operating range; main supply for the periphery
in normal operation
External memory data bus bit 6
: 16-bit data bus; used to connect to external RAM
and program memory
External memory data bus bit 5
: 16-bit data bus; used to connect to external RAM
and program memory
External memory data bus bit 4
: 16-bit data bus; used to connect to external RAM
and program memory
Ground
: 0 V reference
Main core power supply
: 2.7 to 3.6 V only; main supply for the core in normal
operation
External memory data bus bit 3
: 16-bit data bus; used to connect to external RAM
and program memory
External memory data bus bit 2
: 16-bit data bus; used to connect to external RAM
and program memory
External memory data bus bit 1
: 16-bit data bus; used to connect to external RAM
and program memory
External memory data bus bit 0
