4.11.2 e-USB Flash Drive
ATCA-9405 provides a factory option for eUSB Flash Drives. The Flash Drive can be used for local
mass storage, persistent user data storage or booting of operating system and user images. A
low profile 2mm eUSB header on the board is connected to the P2020 to support eUSB
modules from various vendors.
The default assembly SG9ED52M1GG4NEMR from Smart Modular Technology provides 16 GB
of User Flash memory. The module provides sustained read speeds of up to 35 MBps and writes
up to 23 MBps. For connector pin-out and footprint, refer to
Table "eUSB Drive Connector Pin-
out" on page 42 .
4.12 UART Interface
The P2020 provides a dual UART compatible with 16450 and the PC16550D. Both interfaces
consist of four wires RXD, TXD, RTS, and CTS. The interfaces run in full duplex mode and the
baud rates are software programmable.
The first interface COM0 is connected to the FPGA that is able to route the interface to either
the front panel connector and/or to the Terminal server. The connection to the front panel
console connector is implemented via RS-232 transceiver. All four signals (RXD, TXD, RTS, and
CTS) are connected to an RJ45 connector. For connector pin out, refer to Serial Console Ports.
Serial port parameters for the front panel interface are 9600 baud, 8 data bits, no parity bit, and
1 stop bit.
When serial port COM0 is routed to the Terminal Server for console redirection into the base
network, only TXD and RXD signals are used. Serial port parameters for this interface are 9600
baud, 8 data bits, no parity bit, and 1 stop bit.
The second interface COM1 (only signals TXD and RXD) is connected to a standard 16-pin
header for debugging purposes.
4.13 I2C Interface
The P2020 includes a dual I2C controller with open-drain two-wire interfaces that provides
multi-master and master-slave I2C mode support.
