The HCS412 (silicon revision B0) conforms to the device datasheet (DS41099A) with the exceptions described below. HCS412 HCS412 Silicon Revision B0 Errata Sheet 1.0 ERRATA The HCS412 (silicon revision B0) conforms to the device datasheet (DS41099A) with the exceptions described below. 1.1 Transponder Mode 1. This errata sheet applies only when the HCS412 3. Therefore to ensure reliable device operation is used in TRANSPONDER mode, i.e. when when used as a transponder, a 4.7 M 10% configuration option S2LC is configured such resistor must be connected between pin 3 (LC1) that pin LC1 will be used as a transponder inter- and pin 5 (Ground). The resistor ensures suffi- face pin. ……
