1. Data based on characterization results, not tested in production.

2. The physical granularity of the memory is 4 bytes, so cycling is performed on 4 bytes even when a write/erase operation

addresses a single byte.

Input/output specifications

The STNRGPFx2 device includes three different I/O types:

•

Normal I/Os (O or I);

•

Fast I/O (OP);

•

High speed I/O (CLOCK).

The STNRGPFx2 I/Os are designed to withstand the current injection. For the negative injection current of 4 mA,

the resulting leakage current in the adjacent input does not exceed 1 μA

5.3.5

I/O port pin characteristics

Subject to general operating conditions for VDD and TA unless otherwise specified. Unused input pins should not

be left floating.
