CHAPTER 5 RAM MEMORY
Page 13
Figure 5-1 RAM chip, W4 jumper, & battery
INTRODUCTION
RPC-52 models are available with 32K or 128K of
battery backed RAM. RAM may be changed at any
time. RAM is in socket U3.
RAM is automatically backed up when it is installed.
The battery is shared with the clock and controlled by
the reset/watch dog timer. Battery life will depend upon
RAM size, its power consumption, and amount of time
the board is operating. Generally, a battery life from 5
to 10 years can be expected.
This chapter discusses changing RAM, saving and
retrieving variables, running assembly language
programs, and battery maintenance. Figure 5-1 shows
the location of U3, jumper W 4, and the battery.
Increasing RAM size does not increase the program size
RPBASIC-52 can handle. Maximum program and
variable size is 60K. Additional RAM does increase the
amount of space available for PEEK and POKE storage.
CHANGING MEMORY
Different types of memory can be installed at any time.
RPC-52 models come with either 32K or 128K of RAM
installed. Up to 512K can be installed.
To change a memory chip, you need to rem ove the
original chip, install the new one, and set jumper W4.
To install a new memory chip:
1. Turn off power to the RPC-52.
2. Remove the memory chip from U 3.
3. Orient the chip so pin 1 is towards the card edge.
If installing a 32K RAM, place the chip at the
bottom
of the socket (m emor y chip pin 14 goes into
socket pin 16). The top two socket pins in each row
will be empty.
If installing a 128K or 512K, install the chip into the
socket.
4. Check and change , as necessary, jum per W 4 to
conform to the new mem ory.

BATTERY BACKUP
The RPC -52 battery operates the clock and backs up the
RAM when power is off. Battery life will depend upon
RAM size, type, and time the RPC-52 has power applied
to it. You can expect the battery to last between 5 to 10
years.
NOTE: Do not place the RPC-52 circuit on a metal
surface, even with the power off, without
standoffs. Voltage is present on the circuit side
of the board and it is possible to short out the
battery supply through the circuit traces.
Battery voltage is approximately 2.7 volts. The voltage
is measured by placing a volt meter between ground and
the battery clip.
The battery may be replaced by the following type or
equivalent:
Panasonic BR2325
To replace the battery, lift up the holder and push the
battery from behind. To install, simply reverse the
procedure. The batter y may be replaced while pow er is
on. If you replace the batter y with power off, be sure to
reset the date and time. Also, data stored in RAM will
be lost.
