IINJ(PIN)

(2)(3)

IINJ(PIN) must never be exceeded. This is implicitly insured if VIN maximum is respected. If VIN maximum

cannot be respected, the injection current must be limited externally to the IINJ(PIN) value. A positive

injection is induced by VIN>VDD while a negative injection is induced by VIN <VSS. For true open-drain

pads, there is no positive injection current, and the corresponding VIN maximum must always be respected.

Negative injection disturbs the analog performance of the device. See note in Section 20.13: 10-bit ADC

characteristics.

Injected current on VPP pin

Injected current on RESET pin

Injected current on OSC1 and OSC2 pins

Injected current on PB3 (on Flash devices)

Injected current on any other pin(4)

When several inputs are submitted to a current injection, the maximum

ΣIINJ(PIN) is the absolute sum of the

positive and negative injected currents (instantaneous values). These results are based on

characterization with

ΣIINJ(PIN) maximum current injection on four I/O port pins of the device.
