NXP MC68HC16Z1CEH16

The MC68HC16Z1CEH16 is a 16-bit high-speed Microcontroller Control Unit built from standard modules that interface via a common internal bus. Standardization facilitates rapid development of devices tailored for specific applications. System hardware and software allow changes in clock rate during operation. Because the MCUs are a fully static design, register and memory contents are not affected by clock rate changes. The intermodule bus (IMB) is a standardized bus developed to facilitate the design of modular microcontrollers. It contains circuitry that supports exception processing, address space partitioning, multiple interrupt levels and vectored interrupts. The standardized modules in M68HC16 Z-series MCUs communicate with one another via the IMB. Although the full IMB supports 24 address and 16 data lines, M68HC16 Z-series MCUs use only 20 address lines.
