VISBA VIDEO PC PROCESSOR CHIP PIN DESCRIPTION
Name Number I/O Definition
VDD 1, 31, 51 I Voltage supply for 3.3 V.
RAS# 2 O DRAM row address strobe (active low).
DWE# 3 O DRAM write enable (active low).
DA[8:0] 12:4 O DRAM multiplexed row and column address bus.
DBUS[15:0] 28:13 I/O DRAM data bus.
RESET# 29 I System reset (active low).
VSS 30, 50, 80, 100 I Ground.
YUV[7:0] 39:32 O Y is luminance, UV are chrominance data bus for screen video interface. YUV[7:0] for 8-
bit YUV mode.
VSYNC 40 I/O Vertical sync for screen video interface, programmable for rising or falling edge.
HSYNC 41 I/O Horizontal sync for screen video interface, programmable for rising or falling edge.
CPUCLK 42 I RISC and system clock input.
CPUCLK is used only if SEL_PLL[1:0] = 00.
PCLK2X 43 I/O Pixel clock; two times the actual pixel clock for screen video interface.
PCLK 44 I/O Pixel clock qualifier in for screen video interface.
AUX[7:0] 54, 52, 53,
49:45
I/OAuxiliary control pins (AUX0 and AUX1 are open collectors).
LD[7:0] 62:55 I/O RISC interface data bus.
LWR# 63 O RISC interface write enable (active low).
LOE# 64 O RISC interface output enable (active low).
LCS[3,1,0]# 65,66,67 O RISC interface chip select (active low).
LA[17:0] 87:82, 79:68 O RISC interface address bus.
VPP 81 I Digital supply voltage for 5 V.
ACLK 88 I/O Master clock for external audio DAC (8.192 MHz, 11.2896 MHz, 12.288 MHz, 16.9344
MHz, and 18.432 MHz).
AOUT/
SEL_PLL0
89 O Dual-purpose pin. AOUT is the audio interface serial data output
IPins SEL_PLL[1:0] select phase-lock loop (PLL) clock frequency CPUCLK
for the Visba:
00 = bypass PLL.
01 = 54 MHz PLL.
10 =67.5 MHz PLL.
11 = 81 MHz PLL.
ATCLK 90 I/O Audio transmit bit clock.
ATFS/
SEL_PLL1
91 O Dual-purpose pin. ATFS is the audio interface transmit frame sync.
IPins SEL_PLL[1:0] select phase-lock loop (PLL) clock frequency CPUCLK for the Visba.
See the SEL_PLL0 pin above for the settings.
DA9/DOE# 92 O Dual purpose pin: DRAM output enable (active low)/DRAM multiplexed row and column
address bus.
AIN 93 I Audio interface serial data input.
ARCLK 94 I Audio receive bit clock.
ARFS 95 I Audio interface receive frame sync.
TDMCLK 96 I TDM interface serial clock.
TDMDR 97 I TDM interface serial data receive.
TDMFS 98 I TDM interface frame sync.
CAS# 99 O DRAM column address strobe bank 0 (active low).
