High-density Complementary Metal Oxide Semiconductor (HCMOS) Microcontroller

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 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. By Freescale Semiconductor, Inc
