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 TMP1942 family is a 32‑bit RISC microprocessor based on the TX19 core, offering high performance with low power consumption for a variety of electronic applications. It supports both 16‑bit MIPS16™ and 32‑bit TX39 instruction sets and includes a range of integrated peripherals.
The document details the processor’s architecture, pin assignments for 144‑pin QFP and 177‑pin CSP packages, electrical specifications, interrupt structure, DMA and timer resources, as well as troubleshooting guidance for known issues such as LWL/LWR instruction hazards and IDLE mode deadlocks.
