16/32-bit ARM microcontrollers
11.4 DDR SDRAM controller
[1]
All values valid for EMC pads set to fast slew rate at 1.8 V unless otherwise specified (see SDRAMCLK_CTRL register in the
LPC32x0
User manual
).
[2]
CMD_DLY = COMMAND_DELAY bitfield in SDRAMCLK_CTRL[18:14] register, see
External Memory Controller (EMC) chapter in
LPC32x0 User manual
.
[3]
Applies to signals EMC_DQM[3:0], EMC_DYCS[1:0], EMC_RAS, EMC_CAS, EMC_WR, EMC_CKE[1:0].
