Description
A1
May-1-2000 Steven Lin Initial Issued
A2
May-19-2000 Steven Lin 1. Add DAC and PWM application circuits.
2. Add PWM voltage as 2.4V ~ 5.5V in DC characteristic
table.
A3
Jul-3-2000
Steven Lin 1. GENERAL DESCRIPTION, 3rd line: “ …and INC
commands and ten programmable registers provide …”
2. FEATURE, 1st line: 1.8 - 5.5 Volts for DAC output and
2.4 – 5.5 Volts for PWM output.
3. FEATURE, 4th line: “New high fidelity synthesis algorithm”
It’ s deleted for redundant.
4. FEATURE, last line: “Up to 256 voice groups can be used
in single page mode; or extended to 2,048 voice groups
in multi page mode, such as 8-page, 16-page and
32-page.”
5. FUNCTION DESCRIPTION: Modified the description for
more easy readable.
6. STOP Register: When a particular STOP bit is set to “1”,
the corresponding stop signal will be an active high
output.
7. Add CPU interface description in timing diagram,
operation and notified.
8. APPLICATION CIRCUIT: Add a note in number 7, “The
OSC layout on customer’ s PCB should be as closed as
the OSC pad to avoid noise coupling.” for both of DAC
and PWM output application circuit.
A4
Jul-25-2000 Steven Lin 1. APPLICATION CIRCUIT in PWM output diagram: Add a
capacity, 10 uF, between VDD and GND to reduce
voltage fluctuation while PWM outputting.
A5
Oct-25-2000 Steven Lin 1. FEATURE, 1st line: Operating voltage 2.4 ~ 5.5 volts for
both DAC and PWM output.
2. DC spec., DAC voltage: minimum 2.4V.
