frequency of 527 kHz.

9) ASK Receive Choices - valid incoming frequency range (with RATS = 0 and MD = 5) is 431 kHz to

609 kHz.

10) RATS register control of receive data frequency window period is now:

T(min) ~= [(2*MD)+3+RATS]*135ns
T(max) ~= [(2*MD)+3+(6*(RATS+1))]*135ns

11) Clarification: the IrDA/HP-SIR baud rate can be as low as 1200 bps.

12) Specifications in the following tables replace those found in the SEP ’05 CS8130 data sheet

(DS134F1).

POWER SUPPLY SPECIFICATIONS

(T

A

= 25 °C; V+ = 3.0 V, Digital Input Levels: Logic 0 = 0 V,

Logic 1 = V+, Note 1)

Notes: 1. Power supply current specifications are with the supply at 3.0 V. For approximate consumption at

+5.0 V, multiply the above currents by 1.667.

2. Oscillator in low power mode; does not include LED current. Subtract oscillator current if using an

external clock to run the CS8130.

3. Floating digital inputs will not cause the power supply to increase beyond the specification.

4. Does not include LED current, does include oscillator current in low power mode.
