Sample WindowÐBegins when the sample capaci-

tor is attached to a selected channel and ends when

the sample capacitor is disconnected from the se-

lected channel.

The following differences exist between the

270869-002 data sheet and the previous version

(270869-001):

1. Changed data sheet status from ‘‘Product Pre-

view’’ to ‘‘Advance Information’’ and updated as-

sociated notices.

Successive ApproximationÐAn A/D conversion

method which uses a binary search to arrive at the

best digital representation of an analog input.

2. Asynchronous port reset was added to RESET

pin description.

Temperature CoefficientsÐChange in the stated

variable per degree centrigrade temperature

change. Temperature coefficients are added to the

typical values of a specification to see the effect of

temperature drift.

3. ALE disable paragraph was added to ALE pin de-

scription.

4. C , C guidelines clarified in Figure 4.

5. Operating Conditions heading was added.

6. Maximum I per I/O pin was added to Absolute

Maximum Ratings.

Terminal Based CharacteristicÐAn actual charac-

teristic which has been rotated and translated to re-

move zero offset and full scale error.

7. VT , VT , V

, V , and V removed.

HYS OL2 TL

8. V value for ALE included with V

OL1

line to the A/D converter.

RejectionÐAttenuation of noise on the V

9. V

and V

added.

IL1

IL2

10. RRST minimum changed from 40K to 50K.

RRST maximum changed from 225K to 300K.

Zero OffsetÐThe difference between the expected

and actual input voltage corresponding to the first

code transition.

11. I maximum changed from 200 mA to 50 mA.

12. I maximum changed from 15 mA to 18 mA.

13. Typical values for I , I , I , and I

PD DL CC

re-

REF

moved.

DATA SHEET REVISION SUMMARY

14. Note 3 (page 9) was reworded.

15. SEP AC Timings added.

The following differences exist between this data-

sheet and the previous version (270869-003):

16. A/D Absolute Error for Channels

changed to 2 LSB.

0 and

1. Merged 87C51GB Express (270889-001).

2. New order number 272337-001.

17. T clarified.

18. Encryption array paragraph was added.

The following differences exist between the 270869-

003 data sheet and the previous version (270869-

002):

19. Corrected pin numbers on Figure 11 to reflect

PLCC package.

1. Changed data sheet status from ‘‘Advance Infor-

mation’’ to ‘‘Preliminary’’ and updated associated

notices.

2. Added 83C51GB throughout.

3. Added Package and Process Information.

4. Clarified 2 LSB accuracy for channels 0 and 1

in A/D Converter Section.

5. Added ‘‘ROM and EPROM Lock System’’ section

and added 83C51GB to ‘‘Program Lock Bits’’

section.

6. Modified Signature Bytes Table.
