(1) I/F sleep is a programmable parameter that can be set to save power in free-run, sequencer mode when displaying still images on the DMD. When I/F sleep is enabled, any images applied to the input bus to the DLPC2607 device are ignored.
(2) Power for both I/F sleep mode disabled and I/F sleep mode enabled was measured while transferring a full 864 × 480 landscape image at periodic 30 frames per second. The image was a 12 × 6 color checkerboard.
(3) All measurements were taken on a TI internal reference design board at 25°C ambient.
(4) VCC_FLSH power was 0 at the time of the measurement because flash accesses are limited when the ASIC is being configured.
