CHANGED

10/04

Initial release for QFN package variant.

—

10/04

New product release for TQFN package variant.

In the Features section under Peripheral Features, corrected accumulator to

show 48 bits (not 40 bits).

In the Electrical Characteristics table, added Active Current line for 2.2V,

20MHz flash operation; VIH2(MIN) changed from 0.8 x VDDIO to 0.75 x VDDIO;

updated VIH, VIL, VOH, and VOL data to match GBD/FTEC data.

2, 3

12/04

Replaced the package drawing for 56-pin package.

Added lead-free part numbers to the Ordering Information table.

6/05

In the Electrical Characteristics table under LCD Segment Voltage, clarified

wording on VADJ spec to VADJ(MIN) = VADJ and VADJ(MAX) = 0.1V; changed

ISEGxx to 3μA.

10/05

Clarified that flash memory write/erase cycles and data retention specifications

are at +25°C.

Clarified VIH1/VIH3 specifications, matching presented values to test program

values (0.8 x VDDIO); clarified VIH2 specification, matching presented values to

test program values (0.8 x VLCD); clarified VIL2 specification, matching

presented values to test program values (0.2 x VDDIO). These changes do not

affect the testing or operation of the device.
