Pin Function Description

Frame Buffer Port

D15-0

79-76,73-62/

100-97,94-

91,88-81

TTL input/

LVTTL

output

Data port, frame store memory. 16-bit data bus for 16Mb

SDRAM.

A11-0

94-83/

118-107

LVTTL

output

Address port, frame store memory. 12-bit address bus

for 16Mb SDRAM.

RAS\

60/78

LVTTL

output

Row address strobe. RAS\ output for 16Mb SDRAM

frame store memory.

CAS\

61/79

LVTTL

output

Column address strobe. CAS\ output for 16Mb SDRAM

frame store memory.

WE\

58/76

LVTTL

output

Write enable. WE\ output for 16Mb SDRAM frame store

memory.

DQM

57/75

LVTTL

output

Data Qualify. Qualify data for 16Mb SDRAM frame store

read/write operations. State is set by the memory access

mode:

DQM = L, enables memory outputs for read operations and

exposes memory inputs for write operations;

DQM = H, disables memory outputs and masks memory

inputs

RAMCK_IN

100/127

TTL input

Frame store clock input. Frame store input clock to be

routed to RAMCK_OUT if RAMCK_SEL\ = L.

RAMCK_SEL\ 98/125

TTL input

Frame store clock select. Selects either internal or

external clock for 16Mb SDRAM frame store memory. If

RAMCK_SEL\ = H, the internal clock synthesized from

OSC1 is selected. With RAMCK_SEL\ = L, the RAMCK_IN

input is selected.

RAMCK_OUT 99/126

LVTTL

output

Frame store clock output. RAMCK_OUT for 16Mb

SDRAM frame store memory.

Serial Port

SIOA

10/7

25/31

TTL input

Serial address length select. Selects the length of the

serial address:

SIOA

10/7

= H: 10-bits

SIOA

10/7

= L: 7-bits

SIOA0

26/32

TTL input

Serial data address bit 0. . Selects the serial bus address:

SIOA0 = H: 0x6A, 276

SIOA0 = L: 0x4A, 224

SIODATA

24/30

TTL input

Serial data. Data line of the serial port.

SIOCLK

23/29

TTL input

Serial clock. Clock line of the serial port.
