DescriptionThe TMP04090FXXXX is high-performance 4-bit microcontroller incorporating a 16K-word (1 word=16 bits) one-time PROM (OTP).It is pin-compatible with the mask ROM version of TMP04CHOOFXXX.With programs written to their built-in PROMS, the devices operate the same as the mask ROM products.They are therefore optimal for developing software.With an adapter socket, the TMP04090FXXXX can use a general-purpose EPROM programmer for the writing and verification of programs.
The TMP04090FXXXX has the following features including:(1)interrupts:2 external (input pin, general-purpose input/output pin),2 internal (timer/counter, timings); (2)watchdog timer:timer/counter can be used as watchdog timer; (3)PROM writing method:8-bit parallel.The TMP04090FXXX X is a one-time PROM version of the TMP04CHOOFXXX and TMP04CH01FXXX which incorporate mask ROM. Other than the ROM, the configuration and functions of the TMP04090FXXXX are the same as those of the TMP04CHOOFXXX and TMP04CH01 FXXX.
The absolute maximum ratings of the TMP04090FXXXX are:(1)storage temperature:-55 to 125; (2)operating temperature:0 to 40; (3)input voltage:-0.3 to Vdd+0.3V; (4)power supply voltage:-0.3 to 6.0V;(5)power dissipation:1.0W.TOSHIBA is continually working to improve the quality and the reliability of its products. Nevertheless, semiconductor devices in general can malfunction or fail due to their inherent electrical sensitivity and vulnerability to physical stress. It is the responsibility of the buyer, when utilizing TOSHIBA products, to observe standards of safety, and to avoid situations in which a malfunction or failure of a TOSHIBA product could cause loss of human life, bodily injury or damage to property. In developing your designs, please ensure that TOSHIBA products are used within specified operating ranges as set forth in the most recent products specifications.Also, please keep in mind the precautions and conditions set forth in the TOSHIBA Semiconductor Reliability Handbook.
