PIN DESCRIPTION
5.2. Pin Functions
5.2.1. Power supply
Pin Name
Function
VDD
2.7 to 5.5V supply.
This may be the same supply as the controlling microprocessor.
VSS Ground
Note: The peak supply current drawn by the S1D13305 series may be up to ten times the average supply current. The power
supply impedance must be kept as low as possible by ensuring that supply lines are sufficiently wide and by placing 0.47 µF
decoupling capacitors that have good high-frequency response near the device’s supply pins.
5.2.2. Oscillator
Pin Name
Function
XG
Crystal connection for internal oscillator (See section 13). This pin can be driven by an external
clock source that satisfies the timing specifications of the EXT φ0 signal (See section 6.3.6).
XD
Crystal connection for internal oscillator. Leave this pin open when using an external clock
source.
5.2.3. Microprocessor interface
Pin Name
Function
D0 to D7 Tristate input/output pins. Connect these pins to an 8- or 16-bit microprocessor bus.
SEL1, SEL2
Microprocessor interface select pin. The S1D13305 series supports both 8080 family
processors (such as the 8085 and Z80®) and 6800 family processors (such as the 6802
and 6809).
SEL1
0
1
SEL2*
0
0
Interface
8080 family
6800 family
A0 RD WR CS
A0 RD WR CS
A0 E R/W CS
Note: SEL1 should be tied directly to VDD or VSS to prevent noise. If noise does appear on SEL1, decouple it to ground using a
capacitor placed as close to the pin as possible.
