9 / 18 page eorex EM484M1644VTD Recommended Power On and Initialization The following power on and initialization sequence guarantees the device is preconditioned to each user ’s specific needs. (Like a conventional DRAM) During power on, all VDD and VDDQ pins must be built up simultaneously to the specified voltage when the input signals are held in the “NOP” state. The power on voltage must not exceed VDD+0.3V on any of the input pins or VDD supplies. (CLK signal started at same time) After power on, an initial pause of 200 µs is required followed by a precharge of all banks using the precharge command. To prevent data contention on the DQ bus during power on, it is required that the DQM and CKE pins be held high during the initial pause period. Once all banks have been precharged, the Mode Register Set Command must be issued to initialize the Mode Register. A minimum of eight Auto Refresh cycles (CBR) are also required, and these may be done before or after programming the Mode Register. Apr. 2014 www.eorex.com 9/18 |
