• Description: An Introduction To The Mc68331 And Mc68332
• Manufacturer: Freescale Semiconductor, Inc

3.2.2 The M68EVS331 and M68EVS332
The M68331/332 EVS is exactly the same as the M68EVK331/332, but has an additional daughter card
called the M68DICARD. The user communicates with the DICARD, which in turn communicates with the
MCU, with a program called DIBUG (version 1.03 is the latest version). One use for the DICARD is to re-
program the EPROM on the BCC. See Application Snapshot (AS-52) for more information (Snapshots are
available on-line — see 6.2 Freeware Data Systems for more information). The M68DICARD is no longer
supported or sold, and neither is the M68EVS331 or M68EVS332. The M68EVK331 and M68EVK332 re-
place it.
3.2.3 The M68MEVB1632
The M68MEVB1632 is a more sophisticated development board than the M68331/332EVK. It consists of a
platform board (PFB), a plug-in daughtercard called the personality board (MPB), and the M68ICD32 de-
bugger. The PFB has memory sockets, logic analyzer connections, and jumpers which allow the user to
select the state of critical boot-up signals such as the data bus pins and MODCLK. The MPB contains the
MCU and crystal. The system is very versatile because there are MPBs for a number of different devices,
and several MPBs can be used with the same PFB. Unlike the M68331/332EVK, the M68MEVB1632 does
not have onboard EPROM with a monitor. The user must either use pre-programmed ROMs or use the BDM
connector to download code into RAM.
3.2.4 The MMDS1632
The MMDS1632 is an emulator that provides high-speed, real-time hardware and software emulation for
the target system. It replaces the MCU completely. It is designed to work with a package-specific personality
board (PPB) and the MPB. Both of these boards must be purchased separately. The MPB is not necessary
if the user has a target board already built. In this case, a connection from the MMDS1632 can be soldered
or socketed to the connections intended for the MCU. Contact a local Freescale sales office for more infor-
mation on the MMDS1632.
