| 4 | The icE1usb _gateware_ is where pretty much everything happens, |
| 5 | from the E1 Line Interface Unit to the E1 Framer/Deframer, the |
| 6 | picoRISCV soft-core running the [[firmware]] as well as the USB |
| 7 | device peripheral talking to the host PC. |

| 10 | non-volatile memory (SPI flash). It is field-upgradeable via USB. |
