Improved Memory Throughput Using Serial NOR Flash Download White Paper 1Mo

NOR flash remains the preferred non-volatile technology for discrete memories in embedded systems. Today's NOR based SPI memories have reached 108MHz clock rates with a QuadIO (x4) interface to achieve a 54MB/s sustained read throughput while remaining compatible with the original interface specified nearly 25 years ago. The legacy SPI interface and bus protocol is reaching fundamental timing limits that will make difficult further increases to the SPI bus clock rate. This paper will describe both system level and memory device strategies that deal with these timing limitations allowing higher SPI bus throughputs.

This month, Oscium is giving away three of its iMSO-204L dual analogue iOS oscilloscopes, worth USD400 each. Designed with native Lightning compatibility, the iMSO-204L transforms the iPad, iPhone, and iPod touch into an ultra-portable, two-channel oscilloscope.

Since Apple changed its connector, Oscium has been working to bring native compatibility to its customers. The third generation of handheld engineering tools from Oscium, the iMSO-204L is the solution to the connector change, featuring two analogue and four digital channels, capable of 50 MSPS at a 5MHz bandwidth, and with a resolution varying from 200ns/div to 10s/div.
