CS86 Series

(b) Current value that one I/O can provide to the core

= +125

°C*2

*1 : Maximum current for one I/O includes the supply current to the I/O part and the core part.

*2 : The current values change according to the junction temperature. When the junction temperature is not

+125°C,

multiply the value by the following coefficients.

Tj = +111

°C to +125°C : 1.0

Tj = + 91

°C to +110°C : 1.4

Tj =

+ 90

°C : 2.8

Note : How to calculate the number of required supply pins

In case of a frame with 6-layer wiring (2 power supplies)

• Maximum current for one VDD/GND pin

VDDE

= 59 mA/pin calucurated using the value in “(a) Maximum supply pin current for one I/O”

VDDI

= VSS = 59 mA/pin calucurated using the value in “(b) Current value that one I/O can provide to the core”

• Needed supply pin count (internal power supply/external power supply/VSS) : Ni/Ne/Ns

DC internal maximum power-supply current : Iimax, DC external maximum power-supply current : Iemax

= Iimax/59mA, Ne = Iemax/59mA, Ns = Iimax/59mA + Iemax/59mA

WARNING: Semiconductor devices can be permanently damaged by application of stress (voltage, current,

temperature, etc.) in excess of absolute maximum ratings. Do not exceed these ratings.
