MC68HC711G5

Manufacturer Part Number
MC68HC711G5
Description
High-density Complementary Metal Oxide Semiconductor (HCMOS) Microcontroller
Manufacturer
MOTOROLA [Motorola, Inc]
Datasheet
MC68HC11G5
The MC68HC11G5, which includes 16 kilobytes of on-board ROM, is a member of the M68HC11
family of advanced capability MCUs. This device has 512 bytes of on-board static RAM and a non-
multiplexed expanded bus for accessing external memory.
The original MC68HC11 timer system is expanded to contain 3 input capture ports, 4 output
compare ports and 3 software selectable input capture or output compare ports. A new 4-channel
pulse width modulation timer has been added and there is also an event counter timer system.
The serial I/O system consists of an asynchronous NRZ Serial Communications Interface (SCI) plus
a synchronous Serial Peripheral Interface (SPI). The A/D converter is enhanced to 10 bits. The
MC68HC11G5 also includes a real time interrupt circuit and a Computer Operating Properly (COP)
watchdog system, as on the original MC68HC11A8.
The MC68HC11G7, which is similar to the MC68HC11G5 but with 24 kilobytes of ROM instead of
16 kilobytes, is described in Appendix A.
The MC68HC711G5, again similar to the MC68HC11G5 but with 16 kilobytes of EPROM instead
of ROM, is described in Appendix B.
This section outlines the general characteristics and special features of the MC68HC11G5 high-
density complementary metal oxide semiconductor (HCMOS) microcontroller unit (MCU).
