Designing a cellular low power DDR non-volatile memory system
April 14, 2010 // eetimes // 0 commentsDownload White Paper 441Ko
Cellular phone systems continue to rely on NOR flash memory to deliver high read bandwidth to run application code. For current eXecute-In-Place (XIP) systems, NOR flash devices are used to run application code, and high-speed SDRAM is used for frequently accessed data. To increase memory throughput performance, many cellular memory systems now use LPDDR SDRAM as the main system memory for data. This practice creates a memory infrastructure that requires at least two separate buses, one for SDRAM and one for flash.

This month, Trinamic Motion Control is offering you to win one of four TMCM-1043 development kits for its highly integrated, NEMA 17-compatible TMCM-1043 stepDancer stepper motor module.
Offering designers an easy-to-use PC-based GUI that allows one-click modification of motor drive current, micro-stepping and other key parameters, the intuitive kits are custom designed and developed for direct mounting on a NEMA 17 motor. Pre-programmed and pre-configured with all operating parameters to support standard 1.5A (peak) motors, the TMCM-1043 board uses Trinamic´s single-axis TMC2660 stepper motor driver IC, which integrates a motor pre-driver and power MOSFETs.
