Pin Function Description
Data port, frame store memory. 16-bit data bus for 16Mb
SDRAM.
Address port, frame store memory. 12-bit address bus
for 16Mb SDRAM.
Row address strobe. RAS\ output for 16Mb SDRAM
frame store memory.
Column address strobe. CAS\ output for 16Mb SDRAM
frame store memory.
Write enable. WE\ output for 16Mb SDRAM frame store
memory.
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
Frame store clock input. Frame store input clock to be
routed to RAMCK_OUT if RAMCK_SEL\ = L.
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.
Frame store clock output. RAMCK_OUT for 16Mb
SDRAM frame store memory.
Serial address length select. Selects the length of the
serial address:
SIOA_10/7 = H: 10-bits
SIOA_10/7 = L: 7-bits
Serial data address bit 0. . Selects the serial bus address:
SIOA₀ = H: 0x6A, 276
SIOA₀ = L: 0x4A, 224
Serial data. Data line of the serial port.
Serial clock. Clock line of the serial port.
D/A Converter Power.
A/D Converter Power.
A/D Sample Clock Phase Lock Loop Power.
Frame Store Clock Phase Lock Loop Power.
Digital Power. 3.3 volt power for memory interface.
D/A Converter Ground.
