Flash Memory

Functional Description

 

 

4.8.1Flash Memory

The MVME7100 is designed to provide 128 MB of soldered-on NOR flash memory. Two AMD +3.3 V devices are configured to operate in 16-bit mode to form a 32-bit flash bank. This flash bank is also the boot bank and is connected to LBC Chip Select 0 and 1.

Also included is a second bank of NAND flash, up to 32 GB, connected to LBC Chip Select 2. The VPD flash packet(s) will determine which devices are populated and the size of the devices. Programming details can be found in the MVME7100 Single Board Computer Programmer’s Reference manual.

4.8.2NVRAM

The MVME7100 includes one Freescale 512 MB MRAM device connected to the MC864xD device control bus to provide a non-volatile memory that has unlimited writes, fast access and long term data retention without power. The MRAM device selected is also an extended temperature device with an operating range from -40°C to 105°C/-40°F to 221°F. The MRAM is organized as 256 K by 16. Refer to the datasheet for additional information

4.8.3Quad UART (QUART)

The MVME7100 contains one Quad UART device connected to the MC864xD device control bus to provide additional asynchronous serial ports. The Quad UART provides four asynchronous serial ports which are routed to the P2 connector. The TTL-level signals of RX, TX, CTS, and RTS from each port are routed through on-board RS-232 drivers and receivers to the P2 connector where the signals can be picked up by a transition module. The reference clock frequency for the QUART is 1.8432 MHz. All UART ports are capable of signaling at up to 115 Kbaud. Refer to the ST16C554D datasheet for additional details and/or programming information.

4.8.4Control and Timers PLD

The MVME7100 Control and Timers PLD resides on the local bus. The Control and Timers PLD provides the following functions on the board:

zLocal bus address latch

zChip selects for flash banks, MRAM, and Quad UART

zSystem control and status registers

zFour 32-bit tick timers

zWatch Dog Timer

zRTC 1 MHz reference clock
