SWAK
*A
3250883 SWAK / 05/06/2011 Updated Functional Overview (Updated Port Indicators (Added a Note
AASI
“Pin-strapping GREEN#[1] and GREEN#[2] enables proprietary function that
may affect the normal functionality of HX2VL. Configuring Port #1 and #2 as
non-removable by pin-strapping should be avoided.”).
Updated Pin Configurations (Updated Figure 1 and Figure 2 (Pin 37 of the
48-pin TQFP package was named SELF_PWR. It is changed to SELFPWR.)).
Updated Pin Definitions (changed value from 680  to 650 in description of
RREF pin).
Updated Functional Overview (Updated Power Regulator on page 5 (Changed
regulator’s maximum current loading from 200 mA to 150 mA)).
Updated Pin Configuration Options (Updated Power Switch Enable Pin Polarity
(Replaced first two occurrences of the word “setting” with “pin-strapping”)).
Updated Electrical Characteristics (Updated DC Electrical Characteristics
(Changed typical value of I_SUSP parameter from 693.3 µA to 786 µA, changed
maximum value of I_SUSP parameter 693.7 µA to 903 µA, and updated typical
and maximum values of I_CC parameter)).
*B
3324484
AASI
07/25/2011 Changed status from Preliminary to Final.
Updated Pin Configurations (Included CY7C65634 related information).
Updated Pin Definitions (Changed description of OVR# pins from “Default is
Active LOW” to “Active LOW Overcurrent Condition Detection Input” (since the
polarity is not configurable)).
Updated Pin Definitions (Changed description of OVR# pins from “Default is
Active LOW” to “Active LOW Overcurrent Condition Detection Input” (since the
polarity is not configurable)).
Updated Electrical Characteristics (Updated DC Electrical Characteristics
(Updated minimum, typical, and maximum values of R_DN and R_UP parameters
to 81 k103 k and 181 k)).
*C
3336689 SWAK 08/04/2011 No technical updates.
*D
3412885
AASI
10/18/2011 _{Updated Pin Configurations (Updated Figure 1 and Figure 2 (Renamed}
SPI_DI to SPI_MOSI, renamed SPI_DO to SPI_MISO respectively for clarity),
updated Figure 3 (Updated pin 26 to describe the alternate function
I2C_SDA.), updated Figure 4 (Updated to reflect pin 20 as NC)).
Updated Pin Definitions (Renamed SPI_DI to SPI_MOSI, renamed SPI_DO
to SPI_MISO respectively for clarity).
Updated Pin Definitions (Added Note 3 and referred the same note in PWR#).
Minor text edits to add clarity.
*E
3508597
AASI
01/25/2011 _{Updated EEPROM Configuration Options (Removed text, “Strings must}
comply with the USB specification. The first byte (Byte 16) must be the length
of the string in bytes, the second must be 0x03, and the string must be in
ASCII code.” below “Vendor string”, “Product string” and “Serial Number
string”.).
Updated Functional Overview (Updated Overcurrent Detection (Included the
text, “OVR#[n] has a setup time of 20 ns. It takes 3 to 4 ms from overcurrent
detection to de-assertion of PWR#[n].”).
