Revision

Date

Changes

FEB 2006

Advance release.

JUN 2006

Updated part numbers for ordering (Tables 5 & 6), Updated VOH and VOL

specification to include the current load used for testing

JUL 2006

Updated part numbers for ordering (Tables 5 &6). Updated text in sections 3 and 4.

Updated parameter descriptions in sections 5.1 and 5.3. Updated Tspickl, Tspickh,

and Tspidov timing. Corrected Figure SPI Master Timing to use EE_CS. Added foot-

note to XTI table. Removed SCLK/LRCLK relative timing from DAI port timing.

Removed SCLK/LRCLK slave relative timing from DAO port timing.

OCT 2007

Updated the Tspidsu, Tspickl, and Tspickh timing parameters for master mode SPI.

This applies to both SPI ports.

PP1

May 28, 2008

Updated product feature list in Table 2. Updated Figure 19 and Figure 21.

PP2

June 20, 2008

Added typical crystal frequency values in Table Footnote 1 and Min and Max values

of Fxtalin Section 5.8. Removed DSD Phase Modulation Mode from Section

5.17

. Removed reference to MCLK in Section 5.17. Redefined Master mode

clock speed for SCP_CLK in Section 5.11. Redefined DC leakage

characterization data in Section 5.3, correcting units of measurement.

Modified Footnote 1 under Section 5.10.

PP3

September 24, 2008

Removed references to External Parallel Flash / SRAM Interface.

PP4

June 9, 2009

Updated product number references in Section 5.9, Section 6.

, Section 7., Table

.Table 3, and Table 4. For all Active Low pins, changed Active Low pin

designation from “#” character after the pin name to a line over the pin name as in

“EE_CS”. Removed Active Low designation from the BDI_REQ pin in the 128-pin

pinout drawings in Figure 19 and Figure 20, and in the 144-pin pinout drawings in

Figure 21 and Figure 22. Updated the pin names referred to in the timing diagrams

in Figure 9, Figure 10, Figure 17, and Figure 18. Updated the parameters in Section

5.15.

PP5

July 29, 2009

Updated Figure 19, Figure 20, Figure 21. Removed CS495314-CQZ and

CS495314-CQZR from Table 5 and Table 6. Added recommendation that CS4953x4

family be used with new designs. Updated Section 2.

PP6

November 11, 2009

Removed references to UART port. Removed references to 11.2896,

18.432, and 27 MHz frequency clocks in Note 1 in Section 5.8 “Switching

Characteristics — XTI” on page 12 and the Min and Max External Crystal

Operating Frequency values in that same section. Updated Section 5.17

“ Switching Characteristics — DSD® Serial Input Port” on page 23. Section

5.18 “Switching Characteristics — Digital Audio Output Port” on page 24. In

Figure 21, "144-pin LQFP Pin-Out Drawing (CS495313)", on page 32,

moved SCP2_SDA from Pin 106 to Pin 105, deleted duplicate EE_CS from

Pin 25, and designated Pin 140 BDI_REQ as active low. Designated Pin 32,

BDI_REQ as active low In Figure 19, "128-pin LQFP Pin-Out Drawing

(CS495303/CS495313)", on page 30 and in Figure 20, "128-pin LQFP Pin-

Out Drawing (CS495304/CS495314)", on page 31. In Section 5.3, the

parameter, “Input leakage current (all digital pins with internal pull-up

resistors enabled, and XTI)”, Max value changes from 50

μA to 70 μA. In

Section 5.13, the parameter SCP_CLK low to SCP_SDA out valid with

symbol “tiicdov” Max value changes from 18 ns to 36 ns.
