DESCRIPTION
The M37736EHBXXXGP 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 others.
In the M37736EHBXXXGP, as the multiplex method of the external
bus, either of 2 types can be selected.
The M37736EHBXXXGP has the same function as the
M37736MHBXXXGP except that the built-in ROM is PROM. (Refer
to the basic function blocks description.) For program development,
the M37736EHBGS with erasable ROM that is housed in a windowed
ceramic LCC is also provided.

EPROM MODE
The M37736EHBXXXGP 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 1 list the
correspondence between pins and Figure 1 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
CNV
SS, and BYTE are used for the EPROM (equivalent to the
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.

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
_____
___ ___
Erasing
To erase data on this chip, use an ultraviolet light source with a 2537
Angstrom wave length. The minimum radiation power necessary for
erasing is 15 J/cm
2
.
Programming operation
To program the M37733EHBXXXFP, 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)Sunlight and fluorescent lamp contain light that can erase written
information. When using in read mode, be sure to cover the
transparent glass portion with a seal or other materials (ceramic
package product).
(2)Mitsubishi Electric corp. provides the seal for covering the
transparent glass. Take care that the seal does not touch the read
pins (ceramic package product).
(3)Clean the transparent glass before erasing. Fingers’ fat and paste
disturb the passage of ultraviolet rays and may affect badly the
erasure capability (ceramic package product).
(4) A high voltage is used for programming. Take care that over-
voltage is not applied. Take care especially at power on.
(5) The programmable M37736EHBGP that is shipped in blank is
also provided. For the M37736EHBGP, 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.
