Note

Any CHG line activity before the power-on or reset period has expired should be ignored by the host. Operation of this

signal cannot be guaranteed before the power-on/reset periods have expired.

The mXT1664T3 meets the requirements of Microsoft Windows 8.x and later versions.

Parameter

Description

Mutual capacitance

Typical value is between 0.15 pF and 10 pF on a single node.

Cpx

Mutual capacitance load to X

Microchip recommends a maximum load of 300 pF on each X or Y

line. (1)

Cpy

Mutual capacitance load to Y

Cpx

Self capacitance load to X

Microchip recommends a maximum load of 100 pF on each X or Y

line. (1)

Cpy

Self capacitance load to Y

Cpx

Self capacitance imbalance on X

Nominal value is 20.9 pF. Value increases by 1 pF for every 45 pF

reduction in Cpx/Cpy (based on 100 pF load)

Cpy

Self capacitance imbalance on Y

Cpds0

Self capacitance load to Driven Shield

Microchip recommends a maximum load of 100 pF on the Driven

Shield line. (1)

Note

Please contact your Microchip representative for advice if you intend to use higher values.
