2.2 Memory on EB 200

The following memory types are available on the EB 200 evaluation board:

2.2.1 SDRAM Interface

The SDRAM interface consists of 2 Infineon type HYP39S25616DT-7.5 blocks.

 64-Mbyte memory capacity

 32-bit data width

 50 MHz clock frequency

2.2.2 SRAM Interface

The SDRAM interface consists of 2 Samsung type KF3216U6M-EF700000 blocks.

 8-Mbyte memory capacity

 32-bit data width

2.2.3 Flash Interface

Two different Flash types are used for the Flash interface:

1. Socketed boot Flash

 AMD type AM29LV040B-90JC

 512-Kbyte memory capacity

 8-bit data width

 Firmware can be loaded via programmer

 No host interface required to load firmware

2. Boot/user Flash

 AMD type AMD29DL323GB-90EI/T

 4-Mbyte memory capacity

 16-bit data width

 Programming performed with JTAG

 Intended for applications that work directly from the Flash

2.2.4 Serial Flash/EEPROM

The ERTEC 200 supports the following types in “Boot from SPI boot” mode:

 Serial data Flash, 128 Kbytes ATMEL type AT45DB011

 Serial EEPROM, 64 Kbytes ATMEL type AT25HP512

The following jumper settings are necessary:

 SPI block type (see description X11/5,6 in Section 2.1.2 ).



SPI boot (see description X10 in Section 2.1.3).

GPIO[22] and GPIO[23] are used by the boot software for the SPI boot. The chip select of the SPI blocks is activated

with GPIO[22], and the SPI boot mode is selected with GPIO[23].
