Description
TMP68303 is a high-speed, high-function 16-bit microprocessor developed for applications in control devices. TMP68303 uses the 68HC000, the CMOS version of the 68000, as its core processor. It also includes peripheral circuits such as a serial interface, parallel interface, timer, interrupt controller, DMA controller, DRAM controller, stepping motor controller, and address decoder.
In addition, TMP68303 can directly use 68000 development environments and software resources.
