• Manufacturer Part Number: adsp-2185m
• Description: Dsp Microcomputer
• Manufacturer: Analog Devices, Inc.

The Mini-BGA package pinout is shown in the table below. Pin names in bold text replace the plain text named functions when
Mode C = 1. A + sign separates two functions when either function can be active for either major I/O mode. Signals enclosed in
brackets [ ] are state bits latched from the value of the pin at the deassertion of RESET.
The multiplexed pins DT1/FO, TFS1/IRQ1, RFS1/IRQ0, and DR1/FI, are mode selectable by setting Bit 10 (SPORT1 configure) of
the System Control Register. If Bit 10 = 1, these pins have serial port functionality. If Bit 10 = 0, these pins are the external interrupt
and flag pins. This bit is set to 1 by default upon reset.
