11 / 57 page TC59LM818DMB-33,-40 2005-10-19 11/57 Rev 1.4 POWER UP SEQUENCE (1) As for PD , being maintained by the low state ( ≤ 0.2 V) is desirable before a power-supply injection. (2) Apply VDD before or at the same time as VDDQ. (3) Apply VDDQ before or at the same time as VREF. (4) Start clock (CLK, CLK ) and maintain stable condition for 200 µs (min). (5) After stable power and clock, apply DESL and take PD =H. (6) Issue EMRS to enable DLL and to define driver strength and data strobe type. (Note: 1) (7) Issue MRS for set CAS latency (CL), Burst Type (BT), and Burst Length (BL). (Note: 1) (8) Issue two or more Auto-Refresh commands (Note: 1). (9) Ready for normal operation after 200 clocks from Extended Mode Register programming. NOTES: (1) Sequence 6, 7 and 8 can be issued in random order. (2) L = Logic Low, H = Logic High (3) DQ output is Hi-Z state during power upsequence.
