M37735EHLXXXHP
PROM VERSION OF M37735MHLXXXHP
DESCRIPTION
The M37735EHLXXXHP 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.
The M37735EHLXXXHP has the same function as the
M37735MHLXXXHP except that the built-in ROM is PROM. (Refer
to the basic function blocks description.)

BASIC FUNCTION BLOCKS
The M37735EHLXXXHP has the same functions as the
M37735MHBXXXFP except for the following :
(1)The built-in ROM is PROM.
(2) The status of bit 3 of the oscillation circuit control register 1 (address
6F
16) at a reset is different.
(3)The usage condition of bit 3 of the oscillation circuit control register
1 is different.
(4)Part of the processor mode selection method is different.
Accordingly, refer to the basic function blocks description in the
M37735MHBXXXFP except for Figure 1 (bit configuration of
oscillation circuit control register 1), Figure 3 (microcomputer
internal status during reset), and Table 1 (microprocessor mode
selection method).
In the M37735EHLXXXHP, bit 3 of the oscillation circuit control
register 1 must be “0”. (Refer to Figure 1.) Bit 3 is “1” at a reset.
Accordingly, write “0” to bit 3 in the single-chip mode after reset.

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 – A16 to 0016, A15 – A8 to the contents
Figure 3 shows the microcomputer internal status during reset.
Figure 4 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.

M37735EHLXXXHP
PROM VERSION OF M37735MHLXXXHP
EPROM MODE
The M37735EHLXXXHP features an EPROM mode in addition to its
normal modes. When the RESET signal level is “L”, the chip
automatically enters the EPROM mode. Table 2 lists the
correspondence between pins and Figure 5 shows the pin
connections in the EPROM mode.
The EPROM mode is the 1M mode for the EPROM that is equivalent
to the M5M27C101K.
When in the EPROM mode, ports P0, P1, P2, P3
SS and BYTE are used for the EPROM (equivalent to the
CNV
M5M27C101K). When in this mode, the built-in PROM can be
programmed or read from using these pins in the same way as with
the M5M27C101K.
This chip does not have Device Identifier Mode, so that set the
corresponding program algorithm. The program area should specify

Reading
To read the EPROM, set the CE and OE pins to a “L” level. Input the
address of the data (A

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

Programming operation
To program the M37735EHLXXXHP, 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
