OSG

In Section 3.3, stated that SCL and SDA pins can be connected to V

CC

 or 

V

CC_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 I

2

C 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 V

IH

max in DC char table from 3.6V to V

CC_IO

 + 10%

*B

465471

See ECN

OSG

Changed the recommendation for the pull up resistors on I

2

C

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 t

OEoff

 

Changed Icc and power dissipation numbers
