INTRODUCTION

MEMO RY SECTION 5

There a re severa l different mem ory types and ar eas. 

Their types, functions, and address locations are shown

in Table 5-1 below.

The application pro gram is stor ed in a 5-volt only Flash

Program mable and Erasable Read O nly Memor y 

(PEROM ) in socket U23. See SECTION 3, SAVING

PROGRAMS for saving information.

Socket U24 holds 32K, 128K, or 512K of RAM. 

Optionally, a clock/calendar w ith battery backup may be

installed in this socket (see SECTION 7 for installation

inform ation). Mem ory in this soc ket is intended to ho ld

data, although pr ogram s could run from it at greatly

reduced speed. 

Sockets U25 and U26 use 128K byte high speed RAMs

for program execution. These sockets are organized as

128K X 16, for a total of 256K bytes.

Sockets U25 and U26 can be configured for 512K X 8

high speed RAMs through jumper W6. This option was

not available at the time this manual was printed. 

Contact Remote Processing for an update.

ACCESSING RAM

Review the sample program in 'EPROM1' and RAM1

directories. EPRO M1 tra nsfers data from RAM to flash

a character by character basis. Integers and other

numbers are read from or written to in a similar manner. 

RAM 1 stores all da ta types to RA M. View the results

using the monitor.
