TYPICAL APPLICATIONS
TYPICAL APPLICATIONS
DEVELOPMENT SUPPORT
As the 908E622 has the MC68HC908EY16 MCU
embedded, typically all the development tools available for
the MCU also apply for this device. However, due to the
additional analog die circuitry and the nominal +12V supply
voltage, some additional items have to be considered:
nominal 12V rather than 5V or 3V supply
high voltage VTST might be applied not only to IRQ pin,
but IRQ_A pin
MCU monitoring (Normal request time-out) has to be
disabled
For a detailed information on the MCU related
development support see the MC68HC908EY16 datasheet -
section development support.
The programming is principally possible at two stages in
the manufacturing process, first on chip level, before the IC is
soldered onto a pcb board, and second after the IC is
soldered onto the pcb board.
Chip Level Programming
At the Chip level, the easiest way is to only power the MCU
with +5V (see Figure 32), and not to provide the analog chip
with VSUP. In this setup, all the analog pins should be left
open (e.g. VSUP[1:8]), and interconnections between the
MCU and analog die have to be separated (e.g. IRQ - IRQ_A).
This mode is well described in the MC68HC908EY16
datasheet - section development support.
Figure 32. Normal Monitor Mode Circuit (MCU only)
Of course its also possible to supply the whole system with
Vsup instead (12V), as described in Figure 33, page 55.
PCB Level Programming
If the IC is soldered onto the pcb board, its typically not
possible to separately power the MCU with +5V. The whole
system has to be powered up and providing VSUP (see
