Aitech C212

Introduction

The Aitech C212 is a high capacity VMEbus Flash memory board.

The C212 implements the Flash arrays using advanced NAND Flash devices. These devices provide high performance and capacity and have built-in features to support ECC mechanisms (ECC is done externally through software). Aitech FMM technology is supported through the software drivers delivered with the board to provide full hard-disk emulation. The board incorporates no moving parts, resulting in significant decreased power consumption and increased reliability.

The VMEbus interface operates in A32/D32 data access and A32 block transfer (BLT) modes. Throughput of 20 MByte/sec is achieved when A32 block transfer (BLT) mode is used and interfacing with a fast master using the Tundra Universe II VME to PCI Bridge.

The Aitech Flash Memory Manager (FMM) supports interleaved memory access and Error Correction Code (ECC). The Aitech FMM can interleave up to a maximum of 32 memory banks for achieving high performance. The software ECC mechanism is used for applications where high data integrity is required and implemented on the host processor.
