MC68HC16Y3/916Y3
USER’S MANUAL
The MC68HC16Y3 and the MC68HC916Y3 microcontrollers are high-speed 16-bit
control units that are upwardly code compatible with M68HC11 controllers. Both are
members of the M68HC16 Family of modular microcontrollers.
M68HC16 microcontroller units (MCUs) are built up from standard modules that inter-
face via a common internal bus. Standardization facilitates rapid development of de-
vices tailored for specific applications.
MC68HC16Y3 and the MC68HC916Y3 MCUs incorporate a number of different mod-
ules. Refer to Table 1-1 for information on the contents of a particular MCU. (
cates that the module is used in the MCU. All of these modules are interconnected by
the intermodule bus (IMB).
The maximum system clock for MC68HC16Y3 and the MC68HC916Y3 MCUs is 16.78
MHz. An internal phase-locked loop circuit synthesizes the system clock from either a
slow (typically 32.768 kHz) or fast (typically 4.194 MHz) reference, or uses an external
frequency source. System hardware and software support changes in clock rate dur-
ing operation. Because the MCUs are a fully static design, register and memory con-
tents are not affected by clock rate changes.
High-density complementary metal-oxide semiconductor (HCMOS) architecture
makes the basic power consumption low. Power consumption can be minimized by
stopping the system clock. The M68HC16 instruction set includes a low-power stop
(LPSTOP) command that efficiently implements this capability.
