TYPICAL APPLICATIONS
DEVELOPMENT SUPPORT
As the 908E626 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 +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
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
On Chip level the easiest way is to only power the MCU
with +5V (see Figure 16) and not to provide the analog chip
with VSUP, in this setup all the analog pin should be left open
(e.g. VSUP[1:3]) 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 16. Normal Monitor Mode Circuit (MCU only)
Of course its also possible to supply the whole system with
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 providing VSUP (see
