TYPICAL APPLICATIONS
TYPICAL APPLICATIONS
DEVELOPMENT SUPPORT
As the 908E624 has the MC68HC908EY16 MCU
embedded typically all the development tools available for
the MCU also apply for this device, however due to the fact
of the additional analog die circuitry and the nominal +12 V
supply voltage some additional items have to be considered:
nominal 12 V rather than 5.0 or 3.0 V supply
high voltage VTST might be applied not only to IRQ pin,
but IRQ_A pin
MCU monitoring (Normal request timeout) has to be
disabled
For a detailed information on the MCU related
development support see the MC68HC908EY16 data sheet -
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
On Chip level the easiest way is to only power the MCU
with +5.0 V (see Figure 18) and not to provide the analog
chip with VSUP, in this setup all the analog pin should be left
open (e.g. VSUP[1:2]) and interconnections between MCU
and analog die have to be separated (e.g. IRQ - IRQ_A).
This mode is well described in the MC68HC908EY16 data
sheet - section development support.
Figure 18. Normal Monitor Mode Circuit (MCU only)
Of course it is also possible to supply the whole system
with VSUP (12 V) instead as described in Figure 19, page 29.
