DESCRIPTION

The M37735EHBXXXFP 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.
The M37735EHBXXXFP has the same function as the
M37735MHBXXXFP except that the built-in ROM is PROM. For
program development, the M37735EHBFS with erasable ROM that
is housed in a windowed ceramic LCC is also provided. (Refer to the
basic function blocks description.)

BASIC FUNCTION BLOCKS

The M37735EHBXXXFP 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 M37735EHBXXXFP, bit 3 of the oscillation circuit control register
1 must be “0”. (Refer to Figure 1.) Bit 3 is “1” at a reset. Accordingly,

EPROM MODE

The M37735EHBXXXFP 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 list the
correspondence between pins and Figure 4 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

corresponding program algorithm. The program area should specify
address 01000

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

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

.

Programming operation

To program the M37735EHBXXXFP, 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 M37735EHBFP that is shipped in blank is also

provided. For the M37735EHBFP, 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.
