1.4 Summary of M68HC11 Family
Table 1-1 and the following paragraphs summarize the current members of the
M68HC11 family of MCUs. This technical data book describes the MC68HC11A8 ver-
sion and can be used as a primary reference for several other versions of the
M68HC11 family. However, with the exception of the CPU, some newer members dif-
fer greatly from the MC68HC11A8 MCU and their respective technical literature
should be referenced.
Several of the device series within the M68HC11 family have
′x1 and ′x0 versions.
These are identical to the main member of the series but have some of their on-chip
resources disabled. For instance, an MC68HC11A1 is identical to the MC68HC11A8
except that its ROM is disabled. An MC68HC11A0 has disabled EPROM and EE-
PROM arrays. Refer to Table 1-1.
Nearly all series within the M68HC11 family have both a ROM version and an EPROM
version. Any device in the M68HC11 family that has a 7 preceding the 11 is a device
containing EPROM instead of ROM (e.g., MC68HC711E9). These devices operate
exactly as the custom ROM-based version (e.g., MC68HC11E9) but can be pro-
grammed by the user. EPROM-based devices in a windowed package can be erased
and reprogrammed indefinitely. EPROM-based devices in standard packages are
one-time-programmable (OTP). Refer to Table 1-1.
