DC Characteristics

As different combinations of application modules are loaded onto the
eZ80

®

Development Platform, current requirements change. Please see

on page 41 to reference current consumption values for these

different module combinations.

A 0.1-Farad capacitor is provided on the eZ80F92 Flash Module as a
short-term battery backup for the RTC (see the

Schematic Diagrams

page 59). The part number of the capacitor made by Panasonic is
EECS0HDV. The capacitor is connected to RTC_VDD to provide power
to the RTC when main power to the chip is removed; it is also connected
to the 3.3V supply to the chip for recharging. The RTC can operate down
to 3.0V; it requires 10µA of current. The (keep alive) time this capacitor
can supply power to the RTC, from 3.3V to 3.0V, is approximately 3000
seconds, or 50 minutes.

Flash Loader Utility

The Flash Loader utility allows the user a convenient way to program on-
chip Flash memory. Please refer to the

External Flash Loader Product

(PUG0016) for more details.

Mounting the Module

When mounting the eZ80F92 Flash Module onto the eZ80

®

Development

Platform, check its orientation to the platform to ensure a correct fit. Pin 1
of JP1 on the eZ80

®

Development Platform must align with pin 1 of JP1

on the eZ80

®

Development Platform; Pin 1 of JP2 on the eZ80F92 Flash

Module must align with pin 1 of JP2 on the eZ80

®

Development Plat-

form, etc.
