TECHNICAL DATA
MC68HC16Y1
Technical Summary
16-Bit Modular Microcontroller
1 Introduction
The MC68HC16Y1 is a high-speed 16-bit control unit that is upwardly code compatible with M68HC11
controllers. It is a member of the M68300/68HC16 Family of modular microcontrollers.
M68HC16 controllers are built up from standard modules that interface via a common internal bus.
Standardization facilitates rapid development of devices tailored for specific applications.
The MC68HC16Y1 incorporates a true 16-bit CPU (CPU16), a single-chip integration module (SCIM),
an 8/10-bit analog-to-digital converter (ADC), a multichannel communication interface (MCCI), a gen-
eral-purpose timer (GPT), a time processing unit (TPU), a 2 Kbyte standby RAM module with TPU ROM
emulation capability (TPURAM), and a 48 Kbyte masked ROM module (MRM). These modules are in-
terconnected by the Motorola intermodule bus (IMB).
The MC68HC16Y1 can either synthesize an internal clock signal from an external reference, or use an
external clock input directly. Operation with a 32.768 kHz reference frequency is standard, but operation
with a 4.0 MHz reference is available as an option — contact your Motorola representative for more in-
formation. System hardware and software allow changes in clock rate during operation. Because the
MC68HC16Y1 is a fully static design, register and memory contents are not affected by clock rate
changes.
High-density complementary metal-oxide semiconductor (HCMOS) architecture makes the basic power
consumption of the MC68HC16Y1 low. Power consumption can be minimized by stopping the system
clock. The M68HC16 instruction set includes a low-power stop (LPSTOP) command that efficiently im-
plements this capability.
