PROM VERSION OF M37736MHLXXXHP
DESCRIPTION
The M37736EHLXXXHP 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 PROM, 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.
The M37736EHLXXXHP has the same function as the
M37736MHLXXXHP except that the built-in ROM is PROM. (Refer
to the basic function blocks description.)

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.

FUNCTION IN EPROM MODE
1M mode (equivalent to the M5M27C101K)
Reading
To read the EPROM, set the CE and OE pins to a “L” level. Input the
address of the data (A
to the I/O pins D
__ __
the CE or OE pins are in the “H” state.
0 – D7. The data I/O pins will be floating when either
__ __
0 – A16) to be read, and the data will be output
Programming
Programming must be performed in 8 bits by a byte program. To
program to the EPROM, set the CE pin to a “L” level and the OE pin to
a “H” level. The CPU will enter the programming mode when 12.5 V
is applied to the V
with pins A
– D7. Set the PGM pin to a “L” level to being programming.
PP pin. The address to be programmed to is selected
0 – A16, and the data to be programmed is input to pins D0
___
__ __
Programming operation
To program the M37736EHLXXXHP, first set VCC = 6 V, VPP = 12.5
V, and set the address to 01000
pulse, check that the data can be read, and if it cannot be read OK,
repeat the procedure, applying a 0.2 ms programming pulse and
checking that the data can be read until it can be read OK. Record
the accumulated number of pulse applied (X) before the data can be
read OK, and then write the data again, applying a further once this
number of pulses (0.2 ✕ X ms).
When this series of programming operations is complete, increment
the address, and continue to repeat the procedure above until the
last address has been reached.
Finally, when all addresses have been programmed, read with V
V
PP = 5 V (or VCC = VPP = 5.5 V).

SAFETY INSTRUCTIONS
(1) A high voltage is used for programming. Take care that over-
voltage is not applied. Take care especially at power on.
(2)The programmable M37736EHLHP that is shipped in blank is also
provided. For the M37736EHLHP, Mitsubishi Electric corp. does
not perform PROM programming test and screening following the
assembly processes. To improve reliability after programming,
performing programming and test according to the flow below
before use is recommended.
