TECHNICAL DATA
MC68HC16Y1
Technical Summary
16-Bit Modular Microcontroller
www.DataSheet4U.com
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.

The condition code register can be considered as two functional blocks. The MSB, which corresponds
to the CCR in the M68HC11, contains the low-power stop control bit and processor status flags. The
LSB contains the interrupt priority field, the DSP saturation mode control bit, and the program counter
address extension field.
www.DataSheet4U.com
S — STOP Enable
0 = Stop clock when LPSTOP instruction is executed.
1 = Perform NOP when LPSTOP instruction is executed.
MV — Accumulator M overflow flag
Set when overflow into the accumulator M sign bit (AM35) has occurred.
H — Half Carry Flag
Set when a carry from bit 3 in accumulators A or B occurs during BCD addition.
EV — Extension Bit Overflow Flag
Set when an overflow into bit 31 of accumulator M has occurred.
N — Negative Flag
Set when the MSB of a result register is set.
Z — Zero Flag
Set when all bits of a result register are zero.
V — Overflow Flag
Set when twos complement overflow occurs as the result of an operation.
C — Carry Flag
Set when a carry or borrow occurs during arithmetic operation. Also used during shift and rotate oper-
ations to facilitate multiple word operations.
INT[2:0] — Interrupt Priority Mask
The value of this field ($0 to $7) specifies the CPU16 interrupt priority level.
SM — Saturate Mode Bit
When SM is set, if either EV or MV is set, data read from accumulator M using TMRT or TMET will be
given maximum positive or negative value, depending on the state of the AM sign bit before overflow.
PK[3:0] — Program Counter Address Extension Field
This field is concatenated with the program counter to form a 20-bit pseudolinear address.
