External Connections

Figure 3 shows the recommended external connections for the device.

The VPP pin is only used for programming or erasing the Flash memory array, and must be

tied to a 10 K pulldown resistor for normal operation.

The 10 nF and 0.1 µF decoupling capacitors on the power supply lines are a suggested EMC

performance/cost tradeoff.

The external RC reset network (including the mandatory 1K serial resistor) is intended to protect the

device against parasitic resets, especially in noisy environments.

Unused I/Os should be tied high to avoid any unnecessary power consumption on floating lines. An

alternative solution is to program the unused ports as inputs with pull-up.
