I/O CIRCUITS
2.1
Encoder Architectural Overview
2.1.1
ONBOARD EEPROM
The rfHCS362G/362F has an onboard nonvolatile
EEPROM which is used to store user programmable
data. The data can be programmed at the time of pro-
duction and includes the security-related information
such as encoder keys, serial numbers, discrimination
and seed values. All the security related options
are read protected. The rfHCS362G/362F has built-in
protection against counter corruption. Before every
EEPROM write, the internal circuitry also ensures that
the high voltage required to write to the EEPROM is at
an acceptable level.
2.1.2
INTERNAL RC OSCILLATOR
The rfHCS362G/362F has an onboard RC oscillator
that controls all the logic output timing characteristics.
The oscillator frequency varies within ±10% of the
nominal value (once calibrated over a voltage range of
2V – 3.5V or 3.5V – 6.3V). All the timing values
specified in this document are subject to the oscillator
variation.
