TMP88PU74
CMOS 8-Bit Microcontroller
TMP88PU74F
The TMP88PU74 are the high-speed and high performance 8-bit single chip microcomputers
which built in a program storage area (96 Kbytes) and the One-Time PROM of bector table storage
area (256 bytes). The TMP88PU74 is pin compatible with the TMP88CU74. The operations
possible with the TMP88PU74 can be performed by writing programs to PROM. The TMP88PU74
can write and verify in the same way as the TC571000 an EPROM programmer.

TMP88PU74
Operational Description
The configuration and functions of the TMP88PU74 are the same as those of the TMP88CU74,
except in that a one-time PROM is used instead of an on-chip mask ROM.
1.
1.1
Operating Mode
The TMP88PU74 has two modes: MCU and PROM.
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 TMP88CU74 (the TEST/VPP pin cannot
be used open because it has no built-in pull-down resistance).
1.1.1
Program Memory
The TMP88PU74 has a 96 Kbytes (addresses 04000H to 1BFFFH in the MCU mode,
addresses 00000H to 17FFFH in the PROM mode) of program storage area and 256 byte
(addresses FFF00 to FFFFFH in the MCU mode, addresses 1FF00 to 1FFFFH in the
PROM mode) one-time PROM of vector table storage area.

Note 1: 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.
Note 2: Power Dissipation (PD); For PD, it is necessary to decrease 14.3 mW/°C.

Note 1: The recommended operating conditions for a device are operating conditions under which it can be
guaranteed that the device will operate as specified. If the device is used under operating conditions
other than the recommended operating conditions (supply voltage, operating temperature range,
specified AC/DC values etc.), malfunction may occur. Thus, when designing products which include
this device, ensure that the recommended operating conditions for the device are always adhered to.
Note 2: Clock frequency fc: Supply voltage range is specified in NORMAL 1/2 mode and IDLE 1/2 mode.
