The HCS201 parts you have received conform func-

tionally to the Device Data Sheet (DS40198), except for

the anomalies described below.

None.

Clarifications/Corrections to the Data Sheet:

In the Device Data Sheet (DS40198), the follo wing clar-

ifications and corrections should be noted.

Page 18 of DS40198, entitl ed “KEELOQ® Code H opping

Encoder”, for Microchip part HCS201 has been

changed. Table 8-3, AC Characteristics contains

updated information in the Stepper reference voltage

param ete r. The t ab le be low h as been revi se d to ref lec t

these changes.

Standard Operating Conditions (unless otherwis e specified):

Commercial(C): 0°C ≤ TA ≤ 70°C

Industrial(I): -40°C ≤ TA ≤ +85°C

Symbol Parameters Min Typ. Max. Units Conditions

TBP Time to second button press 10+Code

Word Time 26+Code

Word Time ms (Note 1)

TTD Transmit delay from button det ect 12 26 ms

TDB Debounce del ay 6 20 ms

TTO Auto-shutoff timeout period 27 s(Note 2)
