Introduction
The MC68HC05E6 is a member of the M68HC05 family of HCMOS
microcomputers. Features of the MC68HC05E6 include 6K bytes of user
ROM, 160 bytes of EEPROM, a keyboard interface, an A/D converter and
a 16-bit timer. The device is further enhanced by a core timer which
enables real time interrupts at, for example, 8ms intervals and a
watchdog facility which guards against CPU ‘runaway’. The on-board
EEPROM facilitates storage of alterable, non-volatile, user specified
data, such as personalisation data or control parameters. The features
highlighted make the part ideally suited to various control applications,
while the low voltage design and low cost option ensure that it can also
be used in telecommunications applications such as telephone handsets.
NOTE:
For maximum I/O capability, the 44-pin version of the MC68HC05E6 is
recommended, however for cost-sensitive applications a 28-pin version
is also available.
The entire data sheet applies to the 44-pin version of the device,
however some of the features are not available to the user when the part
is bonded in the 28-pin package (see Figure 1).
The MC68HC705E6 is an EPROM version of the MC68HC05E6, with
the user ROM replaced by a similar amount of EPROM. All references
to the MC68HC05E6 apply equally to the MC68HC705E6, unless
otherwise noted.
