Outline and Features The TX19 is a family of high-performance 32-bit microprocessors that offers the speed of a 32-bit RISC solution with the added advantage of a significantly reduce code size of a 16-bit architecture. The instruction set of the TX19 includes as a subset the 32-bit instructions of the TX39, which is based on the MIPS R3000ATM architecture. Additionally, the TX19 supports the MIPS16TM Application-Specific Extensions (ASE) for improved code density. www.DataSheet4U.com suitable The TMP1942 is built on a TX19 core processor and a selection of intelligent peripherals. The TMP1942 is for low-voltage, low-power applications. Features of the TMP1942 include the following: RESTRICTIONS ON PRODUCT USE 070122EBP • 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.
