HCS201 HCS201 Rev. A Silicon Errata Sheet The HCS201 parts you have received conform functionally to the Device Data Sheet (DS40198), except for the anomalies described below. Clarifications/Corrections to the Data Sheet: None. Page 18 of DS40198, entitled "KEELOQ(R) Code Hopping Encoder", for Microchip part HCS201 has been changed. Table 8-3, AC Characteristics contains updated information in the Stepper reference voltage parameter. The table below has been revised to reflect these changes. In the Device Data Sheet (DS40198), the following clarifications and corrections should be noted. Standard Operating Conditions (unless otherwise specified): Commercial(C): 0C TA 70C Industrial(I): -40C TA +85C Symbol Parameters TBP Time to second button press TTD Transmit delay from button detect TDB Debounce delay TTO Auto-shutoff timeout period Min 10+Code Word Time 12 6 Typ. Max. Units 26+Code Word Time ms 26 ms 20 ms Start pulse delay 4.5 FSTEP Stepper output frequency 125 200 250 kHz VSTEP Stepper reference voltage 5.5 6.5 7.5 V TS 27 s ms Conditions (Note 1) (Note 2) VDDB = 3V Note 1: TBP is the time in which a second button can be pressed without completion of the first code word (the intentio was to press a combination of buttons). 2: The auto-shutoff time-out period is not tested. 3: All parameters in this table are characterized but not tested. 2001 Microchip Technology Inc.
