8 Bit Microcontroller TLCS-870/C Series TMP86C846NG TMP86C846NG 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 equipment, 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 malfunction or 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 instruments, 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. No responsibility is assumed by TOSHIBA for any infringements of patents or other rights of the third parties which may result from its use. No license is granted by implication or otherwise under any patent or patent rights of TOSHIBA or others. 021023_C The products described in this document may include products subject to the foreign exchange and foreign trade laws. 021023_F For a discussion of how the reliability of microcontrollers can be predicted, please refer to Section 1.3 of the chapter entitled Quality and Reliability Assurance/Handling Precautions. 030619_S © 2007 TOSHIBA CORPORATION All Rights Reserved Page 2 Date 2005/12/16 2006/6/29 2006/7/27 2006/8/25 2007/1/25 2008/8/29 Revision History Revision 1 First Release 2 Periodical updating.

No change in contents. 4 Contents Revised 5 Contents Revised 6 Contents Revised Caution in Setting the UART Noise Rejection Time When UART is used, settings of RXDNC are limited depending on the transfer clock specified by BRG. The combination "O" is available but please do not select the combination "–". The transfer clock generated by timer/counter interrupt is calculated by the following equation : Transfer clock [Hz] = Timer/counter source clock [Hz] ÷ TTREG set value BRG setting Transfer clock [Hz] 000 fc/13 110 (When the transfer clock generated by timer/counter interrupt is the same as the right side column) fc/8 fc/16 fc/32 The setting except the above 00 (No noise rejection) O O O RXDNC setting 01 (Reject pulses shorter than 31/fc[s] as noise) 10 (Reject pulses shorter than 63/fc[s] as noise) O O – – O – 11 (Reject pulses shorter than 127/fc[s] as noise) – – – O O O – O O O O Table of Contents TMP86C846NG 1.1 Features . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1 1.2 Pin Assignment . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 1.3 Block Diagram . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4 1.4 Pin Names and Functions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5 2.
