General Description
The HT47C06L is an 8-bit, high performance RISC ar-
chitecture microcontroller device specifically designed
for applications that interface directly to analog signals,
such as those from sensors. Its single cycle instruction
and two-stage pipeline architecture make it suitable for
high speed applications.
The advantages of low power consumption, I/O flexibility,
timer functions, oscillator options, RC type A/D converter,
LCD driver, HALT and wake-up functions, enhance the
versatility of these device to suit a wide range of Resistor
to Frequency application possibilities such as sensor sig-
nalwww.DataSheet.net/ processing, remote metering, and particularly suit-
able for use as clinical thermometer MCU device.

Functional Description
Execution Flow
The HT47C06L system clock is derived from a built-in
RC oscillator with external resistor. The system clock is
internally divided into four non-overlapping clocks (T1,
T2, T3 and T4). One instruction cycle consists of four
system clock cycles.
Instruction fetching and execution are pipelined in such
a way that a fetch takes one instruction cycle while de-
coding and execution takes the next instruction cycle.
This pipelining scheme ensures that instructions are ef-
fectively executed in one cycle. Exceptions to this are in-
structions that change the contents of the program
counter, such as subroutine calls or jumps, in which
case, two cycles are required to complete the instruc-
tion.

Program Counter - PC
The 10-bit program counter (PC) controls the sequence
in which the instructions stored in the program ROM are
executed and its contents specify a maximum of 1024
addresses.
After accessing a program memory word to fetch an in-
struction code, the contents of the program counter are
incremented by one. The program counter then points
to the memory word containing the next instruction
code.
