PDF datasheet of 110 KB for the PG640480 family, revision A, without a variant suffix. The number denotes a 640 by 480 dot graphic LCD module. A base sheet like this generally outlines the shared interface, supply ratings, timing and outline common to all versions in the series. Useful for tracing data and clock lines or checking supply presence on a non-working panel. Backlight type and operating range depend on the full ordering code, so pair it with a variant-specific sheet when possible.
