Motorola MVME-6100

Product Introduction

The MVME – 6100 is a high – performance VMEbus single – board computer originally developed by Motorola, now under GE (via Emerson Network Power acquisition). It is the first VMEbus SBC to feature the Tundra Tsi148 interface chip supporting the 2eSST (two edge source synchronous transfer) protocol, which boosts VMEbus practical bandwidth to 320MB/s. Powered by a 1.267 GHz MPC7457 PowerPC processor with a 128 – bit AltiVec parallel processing coprocessor, it delivers robust computing power for real – time data processing and control. It comes with up to 2GB DDR ECC SDRAM, 128MB on – board flash memory, dual Gigabit Ethernet ports, and dual PMC/XMC expansion slots, making it suitable for mission – critical scenarios that demand high reliability, determinism, and scalability.
