minimum,

X7R

The optimal value of this component should be

determined based on the system level micro-cut

immunity requirement. To achieve the specified

power supply rejection, the minimum value

including all tolerances is 0.22 µF. The maximum

specified value including all tolerances is 2 µF.

For optimal EMC performance, this component is

to be placed as close to the VBUF and BUSRTN

pins as possible.

Note:

The total bus capacitance must not exceed the values specified in the PSI5 standard.

R1 must be sized to handle both the programming current at the maximum rated temperature for programming and the operating current at the maximum

rated temperature for operation.

[2]

If the high baud rate is used, NXP recommends reducing the value of C2. The actual value depends on the bus configuration and number of slaves.

Purpose

General

purpose

82 Ω, 5 %,

200 PPM

The optimal value of this component should be

determined by the system level communication,

EMC, and ESD testing.

For proper device function, the minimum

value can be 0 Ohms. The maximum value is

determined by the minimum bus voltage provided

at the module pin and the minimum operating

voltage of the device. To meet the minimum

PSI5 operating voltage at the module pin, the

maximum resistance including all tolerances is

89.0 Ohms.

VCC filtering and signal damping

General

purpose

27 Ω, 5 %,

200 PPM

The optimal value of this component should be

determined by the system level communication,

EMC, and ESD testing.

For proper device function, the minimum

value can be 0 Ohms. The maximum value

is determined by the minimum bus voltage

provided at the module pin. To meet the minimum

PSI5 operating voltage at the module pin, the

maximum resistance including all tolerances is

66.6 Ohms. If the low response current is used,

the maximum resistance including all tolerances

is 133 Ohms.
