Product Summary
The TS68230CFN10 is a parallel interface/timer (PI/T). It provides versatile double buffered parallel interfaces and a system oriented timer for TS68000 systems. The TS68230CFN10 operates in unidirectional or bidirectional modes, either 8 or 16 bits wide. The PI/T ports allow use of vectored or auto-vectored interrupts, and also provide a DMA request pin for connection to the 68440 direct memory access controller (DMAC) or a similar circuit. The PI/T timer contains a 24-bit wide counter and a 5-bit prescaler. The timer may be clocked by the system clock (PI/T CLK pin) or by an external clock (TIN pin), and a 5-bit prescaler can be used. The TS68230CFN10 can generate periodic interrupts, a square wave, or a single interrupt after a programmed time period. It can also be used for elapsed time measurement or as a device watchdog.
