M37733MHLXXXHP
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
DESCRIPTION
The M37733MHLXXXHP is a single-chip microcomputer using the
7700 Family core. This single-chip microcomputer has a CPU and a
bus interface unit. The CPU is a 16-bit parallel processor that can be
an 8-bit parallel processor, and the bus interface unit enhances the
memory access efficiency to execute instructions fast. This
microcomputer also includes a 32 kHz oscillation circuit, in addition
to the ROM, RAM, multiple-function timers, serial I/O, A-D converter,
and so on.
Its strong points are the low power dissipation, the low supply voltage,
and the small package.

This pin controls the processor mode. Connect to Vss for the single-chip mode and the memory
expansion mode, and to Vcc for the microprocessor mode.
When “L” level is applied to this pin, the microcomputer enters the reset state.
These are pins of main-clock generating circuit. Connect a ceramic resonator or a quartz-
crystal oscillator between X
IN
and X
OUT
. When an external clock is used, the clock source should
be connected to the X
IN
pin, and the X
OUT
pin should be left open.
This pin functions as the enable signal output pin which indicates the access status in the internal
bus. When output level of
E
signal is “L”, data/instruction read or data write is performed.
In the memory expansion mode or the microprocessor mode, this pin determines whether the
external data bus has an 8-bit width or a 16-bit width. The data bus has a 16-bit width when “L”
signal is input and an 8-bit width when “H” signal is input.
Power source input pin for the A-D converter. Externally connect AVcc to Vcc and AVss to Vss.
This is reference voltage input pin for the A-D converter.
In the single-chip mode, port P0 becomes an 8-bit I/O port. An I/O direction register is available so
that each pin can be programmed for input or output. These ports are in the input mode when
reset.
In the memory expansion mode or the microprocessor mode, these pins output address (A
0
– A
7
).
In the single-chip mode, these pins have the same functions as port P0. When the BYTE pin is set
to “L” in the memory expansion mode or the microprocessor mode and external data bus has a
16-bit width, high-order data (D
8
– D
15
) is input/output or an address (A
8
– A
15
) is output. When
the BYTE pin is “H” and an external data bus has an 8-bit width, only address (A
8
– A
15
) is output.
In the single-chip mode, these pins have the same functions as port P0. In the memory expansion
mode or the microprocessor mode, low-order data (D
0
– D
7
) is input/output or an address
(A
16
– A
23
) is output.
In the single-chip mode, these pins have the same function as port P0. In the memory expansion
mode or the microprocessor mode,
R/W
,
BHE
, ALE, and
HLDA
signals are output.
In the single-chip mode, these pins have the same functions as port P0. In the memory expansion
mode or the microprocessor mode, P4
0
, P4
1
, and P4
2
become
HOLD
and
RDY
input pins, and a
clock
φ
1
output pin, respectively. Functions of the other pins are the same as in the single-chip
mode. However, in the memory expansion mode, P4
2
can be selected as an I/O port.
In addition to having the same functions as port P0 in the single-chip mode, these pins also
function as I/O pins for timers A0 to A3 and input pins for key input interrupt input (
KI
0
–
KI
3
).
In addition to having the same functions as port P0 in the single-chip mode, these pins also
function as I/O pins for timer A4, input pins for external interrupt input (
INT
0
–
INT
2
) and input pins
for timers B0 to B2. P6
7
also functions as sub-clock
φ
SUB
output pin.
In addition to having the same functions as port P0 in the single-chip mode, these pins function
as input pins for A-D converter. P7
2
to P7
5
also function as I/O pins for UART2. Additionally, P7
6
and P7
7
have the function as the output pin (X
COUT
) and the input pin (X
CIN
) of the sub-clock
(32 kHz) oscillation circuit, respectively. When P7
6
and P7
7
are used as the X
COUT
and X
CIN
pins,
connect a resonator or an oscillator between the both.
In addition to having the same functions as port P0 in the single-chip mode, these pins also
function as I/O pins for UART 0 and UART 1.

M37733MHLXXXHP
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
BASIC FUNCTION BLOCKS
The M37733MHLXXXHP has the same functions as the
M37733MHBXXXFP except for the package and the reset circuit.
Refer to the section on the M37733MHBXXXFP.
ADDRESSING MODES
The M37733MHLXXXHP has 28 powerful addressing modes. Refer
to the “7700 Family Software Manual” for the details.
MACHINE INSTRUCTION LIST
RESET CIRCUIT
The microcomputer is released from the reset state when the
RESET
pin is returned to “H” level after holding it at “L” level with the power
source voltage at 2.7 – 5.5 V. Program execution starts at the address
formed by setting address A
23
– A
16
to 00
16
, A
15
– A
8
to the contents
of address FFFF
16
, and A
7
– A
0
to the contents of address FFFE
16
.
Figure 3 shows an example of a reset circuit. When the stabilized
clock is input from the external to the main-clock oscillation circuit,
the reset input voltage must be 0.55 V or less when the power source
voltage reaches 2.7 V. When a resonator/oscillator is connected to
the main-clock oscillation circuit, change the reset input voltage from
“L” to “H” after the main-clock oscillation is fully stabilized.
The status of the internal registers during reset is the same as the
M37733MHBXXXFP’s.
_____
The M37733MHLXXXHP has 103 machine instructions. Refer to the
“7700 Family Software Manual” for the details.
