Product Description
The Bt485A RAMDAC is designed speci-
cally for high-performance, high-resolution
color graphics applications. The wide input
pixel port and internal multiplexing modes
enable TTL-compatible interfacing to the
frame buffer, while maintaining video data
rates required for high refresh rate, high-reso-
lution color graphics. The Bt485A is func-
tionally and software backwards-compatible
to the Bt484 and Bt485.
Included are eight byte-wide pixel input
ports, three 256 x 8 color lookup tables with
triple 8-bit video D/A converters (cong-
urable for either 6-bit or 8-bit D/A converter
operation), and a programmable 64 x 64 x 2
cursor with its own color palette. The Bt485A
may alternately be congured for a lower per-
formance VGA mode, where 8 bits of VGA
pixel data (from a VGA controller) are input
through a separate VGA pixel port.
Several operational modes are supported
by the 32 pins allocated for the P[0:7] (A–D)
port including 8-bit pseudo color, 16- and 24-
bit true color, and various packed and sparse
pixel formats. The color palette may be
bypassed in any of the true-color modes.
The Bt485A generates RS-343A-compati-
ble video signals into a doubly terminated 75
load.
