1999-12-09 Interfacing 64Mb HSDRAM to Motorola's MPC860 processor family
The Motorola MPC860 32-bit PowerPC-compatible processors are used for high performance networking and data communications applications. These processors have a 32-bit external memory bus which supports a maximum read and write bandwidth of 200MBps using 7.5ns HSDRAM. The MPC860 has two user programmable memory controller modules called UPMs to eliminate the need for any external memory controller logic. Generally only one UPM is required to support external memory. The other UPM is typically used to control boot ROM or a system peripheral. In addition, the processor has an internal refresh generator, page size registers, and dynamic bus sizing to simplify the interface to HSDRAM devices. The processor is available in 33MHz, 50MHz, and 66MHz clock speed options. This application note describes the 50MHz version and how a 64Mb HSDRAM is interfaced with it.
