# Expected Package

* QFP 256 pin?
* Largest option from Greatek: LQFP-256-0.4mm
  - LQFP
  - 28x28mm size
  - 256 pins
  - 0.4mm pitch
  - 1.0mm lead length
  - body height 1.4mm

# Functionality and Pincount (NOT FINAL, LIKELY TO CHANGE):

Essential:

* 5x RGMII Ethernet - 5x18 = 90 pins [[shakti/m_class/RGMII/]]
* 2x USB ULPI - 2x12 = 24 pins [[shakti/m_class/ULPI/]]
* SDRAM - 39 pins [[shakti/m_class/sdram/]]
* UART - 2 pins
* JTAG - 4 pins [[shakti/m_class/JTAG/]]
* 1.8v Core Power Vdd - 13 pins
* 1.8v Core Power Vss - 13 pins
* 3.3v IO Power Vdd - 10 pins
* 3.3v IO Power Vss - 10 pins
* Reset - 1 pin
* PLL - 5 pins
* SPI - 4 pins [[shakti/m_class/SPI/]]

non-essential:

* GPIO - 16 pins
* EINT - 3 pins
* I2C - 2 pins
* QSPI - Could share with SPI - 6 pins [[shakti/m_class/QSPI/]]
* SD/MMC - Could share with SPI - 4 pins

Total: **246** pins (10 spare)

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)
