HC210W
Symbol
For information on which I/O banks support memory interface IOEs, refer to the Description, Architecture, and
Features chapter in the HardCopy II Device Family Data Sheet section in volume 1 of the HardCopy Series Handbook.
The resistance tolerances for calibrated SOCT and POCT are at the time of initial of calibration. If the temperature
or voltage changes over time, the tolerance may also change.
This table applies only to the HC210W device.
