How To Use the Serial Data Interface
Electrical Requirements
Figure 5
illustrates electrical characteristics for the serial inter-
face bus used with the W204. Devices send data over the bus
with an open drain logic output that can (a) pull the bus line
low, or (b) let the bus default to logic 1. The pull-up resistors
on the bus (both clock and data lines) establish a default logic
1. All bus devices generally have logic inputs to receive data.
Although the W204 is a receive-only device (no data
write-back capability), it does transmit an

pulse after each byte is received. Thus, the SDATA line can
both transmit and receive data.
The pull-up resistor should be sized to meet the rise and fall
times specified in AC parameters, taking into consideration
total bus line capacitance.
