It is pin-compatible with the TMP88CS42NG (Mask ROM version). The TMP88PS42NG can realize operations equivalent to those of the TMP88CS42NG by programming the on-chip PROM. www.DataSheet4U.com Product No. TMP88PS42NG ROM (EPROM) 65536 bytes RAM 2176 bytes Package SDIP64-P-750-1.78 MaskROM MCU TMP88CS42NG 1.1 Features 1. 8-bit single chip microcomputer TLCS-870/X series - Instruction execution time : 0.20 µs (at 20 MHz) - 181 types & 842 basic instructions 2. 35 interrupt sources (External : 6 Internal : 29) 3. Input / Output ports (55 pins) Large current output: 24pins (Typ. 20mA), LED direct drive 4. Prescaler - Time base timer Divider output function (DVO) 5. Watchdog Timer Select of "internal reset request" or "interrupt request". 6. 16-bit timer counter: 1 ch - Timer, External trigger, Window, Pulse width measurement, Event counter, Programmable pulse generate (PPG) modes 7. 16-bit timer/counter(CTC): 1ch - CTC:Timer,event counter or PPG (Programmable Pulse) output 060116EBP • The information contained herein is subject to change without notice. 021023_D • TOSHIBA is continually working to improve the quality and 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 comply with the standards of safety in making a safe design for the entire system, and to avoid situations in which a malfunction or failure of such TOSHIBA products 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 TOSHIBA products specifications. Also, please keep in mind the precautions and conditions set forth in the “Handling Guide for Semiconductor Devices,” or “TOSHIBA Semiconductor Reliability Handbook” etc. 021023_A • The TOSHIBA products listed in this document are intended for usage in general electronics applications (computer, personal equip- ment, office equipment, measuring equipment, industrial robotics, domestic appliances, etc.). These TOSHIBA products are neither intended nor warranted for usage in equipment that requires extraordinarily high quality and/or reliability or a malfunctionor failure of which may cause loss of human life or bodily injury (“Unintended Usage”). Unintended Usage include atomic energy control instruments, airplane or spaceship instruments, transportation instruments, traffic signal instruments, combustion control instruments, medical instru- ments, all types of safety devices, etc. Unintended Usage of TOSHIBA products listed in this document shall be made at the customer's own risk. 021023_B • The products described in this document shall not be used or embedded to any downstream products of which manufacture, use and/or sale are prohibited under any applicable laws and regulations. 060106_Q • The information contained herein is presented only as a guide for the applications of our products.
