 # Expected Package
 * QFP 200 pin?
 
-# Functionality and Pincount:
-* 5x RGMII Ethernet - 5x12 = **60 pins**
-* 2x USB ULPI - 2x12 = **24 pins**
-* GPIO (plain and EINT) - **? pins**
-* SDRAM - 16-bit data, 9-bit addr, rd/wr - **approx 30 pins?**
-* I2C - **2 pins**
-* SPI - assuming 4-pin - **4 pins**
-* QSPI - **6 pins**
-* JTAG - Can't read nmigen well enough, assuming TCK, TDO, TMS, TDI - **4 pins**
-* Power Vdd and Vss - **? pins**
+# Functionality and Pincount (NOT FINAL, LIKELY TO CHANGE):
+* 5x RGMII Ethernet - 5x12 = 60 pins
+* 2x USB ULPI - 2x12 = 24 pins
+* GPIO - 16 pins
+* EINT - 3 pins
+* SDRAM - 39 pins
+* UART - 2 pins
+* I2C - 2 pins
+* SPI - 4 pins
+* QSPI - Could share with SPI - 6 pins
+* SD/MMC - Could share with SPI - 4 pins
+* JTAG - 4 pins
+* Power Vdd - 8 pins
+* Power Vss - 8 pins
+* Reset - 1 pin
+* PLL - 5 pins
 
-Total (**not including power and GPIO pins**): 130 pins
+Total: **186** pins
+
+GPIO, EINT, Vdd, Vss, SDRAM, reset, PLL pin counts come from the LS180 pinmux definitions. 
 
 RGMII pinout count comes from [here](https://web.pa.msu.edu/hep/atlas/l1calo/hub/hardware/components/micrel/rgmii_specification_hp_v1.3_dec_2000.pdf)
