TYPICAL APPLICATIONS
DEVELOPMENT SUPPORT
As the 908E621 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 V
TST
might be applied not only to IRQ
terminal, but IRQ_A terminal
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 30
), and not to provide the analog chip
with VSUP. In this setup all the analog terminal should be left
open (e.g. VSUP[1:8]) and interconnections between 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 30. Normal Monitor Mode Circuit (MCU only)
Of course its also possible to supply the whole system with
Vsup instead (12V) as described in
Figure 31
