SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER

DESCRIPTION

The M37736MHLXXXHP 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.
In the M37736MHLXXXHP, as the multiplex method of the external
bus, either of 2 types can be selected.

SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER

BASIC FUNCTION BLOCKS

The M37736MHLXXXHP has the same functions as the
M37736MHBXXXGP except for the package and the reset circuit.
Refer to the section on the M37736MHBXXXGP.

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
of address FFFF
Figure 1 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
M37736MHBXXXGP’s.

RESET

Note. In this case, stabilized clock is input from the
