CHAPTER 8 COMPONENTS OF THE MINI-PAM
battery charger is connected, as it increases basic power consumption
from 0.7 W to 1.5 W.
The information shown on the LC-display is intentionally
restricted to the most relevant parameters. Additional information can
be called on display in connection with the 51 menu points and by
entering the MEMORY.
8.1.6 Electronic components
The extremely compact design of the MINI-PAM is a
consequence of recent progress in miniaturization of solid state
integrated circuits. The central processing unit features a powerful
CMOS microcontroller. The program software is stored in a CMOS
EPROM. This EPROM is readily accessible after removing the
bottom of the MINI-PAM (see 11.4) and can be exchanged by the
user, if program up-dates become available. A CMOS RAM with 128
kB serves as data memory, providing storage capacity for 4000 data
sets.
