Orig. of
Change Description of Change
** 430449 03/03/06 OSG New data sheet
*A 434754 03/24/06 OSG In Section 3.3, stated that SCL and SDA pins can be connected to VCC or
VCC_IO
Changed sections 3.5, 3.18.1 and pin descriptions of SCL, SDA to indicate that
since DISCON=1 after reset, an EEPROM or EEPROM emulation is required
on the I2C interface
In pin description table, renamed pin 2H (Reserved) to Ground
In Section 6, added statement “The GPIO’s are not over voltage tolerant,
except the SCL and SDA pins, which are 3.3V tolerant“
In Section 8,added a footnote to the DC char table stating that AVcc can be
floated in low power mode
In Section 8, changed VIHmax in DC char table from 3.6V to VCC_IO + 10%
*B 465471 See ECN OSG Changed the recommendation for the pull up resistors on I2C
Split Icc into 4 different values, corresponding to the different voltage supplies
Changed Isus typical to 20uA and 220uA
Added section 3.9.3 on suspend current considerations
*C 484726 See ECN ARI Removed all references the part number CY7C68055. Corrected the bullet in
Features to state that 24 GPIO’s are available. Added the Test ID (TID#) to the
Features on the front page. Made changes to the block diagram on the first
page (this is now a Visio drawing instead of a Framemaker drawing). Corrected
the Ambient Temperature with Power Supplied. Moved figure titles to meet the
new template. Checked grammar. Took out 9-bit address bus from the block
diagram on the first page. Corrected Figure 4.1
*D 492009 See ECN OSG Added Icc data in DC Characteristics and Maximum Power dissipation
*E 500408 See ECN OSG Changed ESD spec to 1500V
*F 502115 See ECN OSG Changed ESD spec to 2000V and 1500V only for SCL and SDA pins.
Added min spec for tOEoff
Changed Icc and power dissipation numbers
