TOSHIBA TMP88PS38BNG

TMP88PS38B
CMOS 8-Bit Microcontroller
TMP88PS38BNG/FG
The TMP88PS38B is the high-speed and high performance 8-bit signal chip microcomputers
which built in a program storage area (64 Kbytes), an OSD font storage area (24 Kbytes) and the
one-time PROM of vector table storage area (256 bytes). The TMP88PS38B is pin compatible with
the TMP88CS38B. The operation possible with the TMP88PS38B can be performed by writing
programs to PROM. The TMP88PS38B can write and verify in the same way as the TC571000D an
EPROM programmer.

TMP88PS38B
Operational Description
The configuration and function of the TMP88PS38B are the same as those of the TMP88CS38B,
except in that a one-time PROM is used instead of an on-chip mask ROM.
1.
Operation Mode
The TMP88PS38B has two mode: MCU and PROM.
1.1
MCU Mode
The MCU mode is activated by fixing the TEST/VPP pin at low level.
In the MCU mode, operation is the same as with the TMP88CS38B.
1.1.1
Program Memory
The TMP88PS38B has a 64 Kbytes (Addresses 04000H to 13EFFH in the MCU mode,
addresses 10000H to 1FEFFH in the PROM mode) of program storage area, 24 Kbytes
(Addresses 20000H to 25FFFH in the MCU mode, addresses 0A000H to 0FFFFH in the
PROM mode) and 256 bytes (Addresses FFF00H to FFFFFH in the MCU mode, addresses
1FF00H to 1FFFFH in the PROM mode) one-time PROM of vector table storage area.

Input/Output Circuit for Pins
(1) Control pins
The TMP88PS38B is identical to the TMP88CS38B and TMP88CM38B/CP38B
except that it has a TEST pin without a pull-down resistor.
R
R = 1 kΩ (typ.)
Note:
A pull-down resistor is not included.
Figure 1.2 TEST Pin
(2) I/O ports
The input/output circuit for the TMP88PS38B I/O port is the same as that for the
TMP88CS38B and TMP88CM38B/CP38B.
1.2
PROM Mode
The PROM mode is used to write and verify programs with a general-purpose PROM
programmer. The high-speed programming mode can be used for program operation.
The TMP88PS38B is not supported an electric signature mode, so the ROM type must be set
to TC571000D.

Programming Flowchart (High-speed Programming Mode)
The high-speed programming mode is achieved by applying the program voltage (+12.75 V) to
the VPP pin when Vcc = 6.25 V. After the address and input data are stable, the data is
programmed by applying a single 0.1ms program pulse to the PGM input. The programmed
data is verified. If incorrect, another 0.1ms program pulse is applied. This process should be
repeated (up to 25 times) until the program operates correctly. After that, change the address
and input data, and program as before. When programming has been completed, the data in all
addresses should be verified with Vcc = Vpp = 5 V.

Writing Method for General-purpose PROM Program
(1) Adapters

(2) PROM programmer specifying
i)
PROM type is specified to TC571000D. (Note 1)
Writing voltage: 12.75 V (high-speed programming mode)
ii) Data transfer (copy) (Note 1)
In the TMP88PS38B, EPROM is within the addresses 10000H to 1FEFFH (Program
storage area) and 0A000H to 0FFFFH (OSD font area) and 1FF00H to 1FFFFH (Vector
table storage area). Data is required to be transferred (copied) to the addresses where
it is possible to write. The program area in MCU mode and PROM mode is referred to
“Program memory area” in Figure 1.1.
iii) Writing address is specified. (Note 1)
Start address:0A000H
End address: 1FFFFH
(3) Writing
Writing/Verifying is required to be executed in accordance with PROM programmer
operating procedure.
Note 1: The specifying method is referred to the PROM programmer description. Either write the
data FFH to the unused area or set the PROM programmer to access only the program
storage area.
Note 2: When MCU is set to an adapter or the adapter is set to PROM programmer, a position of
pin 1 must be adjusted. If the setting is reversed, MCU, the adapter and PROM program
is damaged.

Note: The absolute maximum ratings are rated values which must not be exceeded during operation,
even for an instant. Any one of the ratings must not be exceeded. If any absolute maximum rating is
exceeded, a device may break down or its performance may be degraded, causing it to catch fire or
explode resulting in injury to the user. Thus, when designing products which include this device,
ensure that no absolute maximum rating value will ever be exceeded.

Oscillation for OSD
The frequency generated in LC oscillation can be obtained using the following equations.
f=
1
2π LC
,C =
C1・C2
C1 + C2
C1 is not fixed at a constant value. It can be changed to tune into the desired frequency.
Note 1: Toshiba’s OSD circuit determines a horizontal display start position by counting clock
pulses generated in LC oscillation. For this reason, the OSD circuit may fail to detect clock
pulses normally, resulting in the horizontal start position becoming unstable, at the
beginning of oscillation, if the oscillation amplitude is low.
Changing L and C2 from the values recommended for a specific frequency may hamper a
stable OSD display.
If the LC oscillation frequency is the same as a high-frequency clock value, the oscillation of
the high-frequency oscillator may cause the LC oscillation frequency to fluctuate, thus
making OSD displays flicker.
When determining these parameters, please check the oscillation frequency and the
stability of oscillation on your TV sets.
Also check the determined parameters on your final products, because the optimum
parameter values may vary from one product to another.
Note 2: When using the LSI package in a strong electric field, such as near a CRT, electrically shield
the package so that its normal operation can be maintained.

Note 1: When Vcc power supply is turned on or after, Vpp must be increased.
When Vcc power supply is turned off or before, Vpp must be increased.
Note 2: The device must not be set to the EPROM programmer or picked up from it under applying the
program voltage (12.75 V ± 0.25 V) to the Vpp pin as the device is damaged.
Note 3: Be sure to execute the recommended programing mode with the recommended programing
adaptor. If a mode or an adaptor except the above, the misoperation sometimes occurs.
