DESCRIPTION
The X68C75 is a highly integrated peripheral for the
68HC11 family of microcontrollers. The device inte-
grates 8K-bytes of 5V byte-alterable nonvolatile memory,
2 bidirectional 8-bit ports, 16 general purpose registers,
programmable internal address decoding and a multi-
plexed address and data bus.
The 5V byte-alterable nonvolatile memory can be used
as program storage, data storage, or a combination of
both. The memory array is separated into two 4K-byte
sections which allows read accesses to one section
while a write operation is taking place in the other
section. The nonvolatile memory also features Software
Data Protection to protect the contents during power
transitions, and an advanced Block Protect register
which allows individual blocks of the memory to be
configured as read-only or read/write.
