3.12.6 PCD2.M110/M120/M150

The user memory for these CPUs can be expanded as follows:

CPU type Expansion option Available memory for extension memory1) PCD2.M110/M120 with hardware version < H

RAM: 1 Mbit / 128 Kbytes EPROM: 1 Mbit / 128 Kbytes Flash EPROM: 1 Mbit / 112 Kbytes

24 Kbytes 24 Kbytes 24 Kbytes PCD2.M110/M120 with hardware version >= H and firmware version > V006

RAM: 4 Mbit / 512 Kbytes EPROM: 4 Mbit / 512 Kbytes Flash EPROM: 4 Mbit / 448 Kbytes

As the price differences between the different memory chips are very small, we rec- ommend the use of the following types:

1) Where RAM components not approved by Saia are used, there is a risk of losing data 2) The use of EPROMs is obsolete; use Flash EPROM instead 3) Flash EPROM is supported from firmware version 002 only 4) To hold the configuration, a portion of memory is lost, so for this chip,112 Kbytes rather than 128 are available to the user
