CMOS fixed-point digital signal processor provides a 100 ns instruction cycle time with 16/32-bit architecture. The device includes 544 words of on-chip data RAM, 4K words of on-chip program ROM, and 128K words of total program and data memory space. It integrates a 32-bit ALU and accumulator, a 16 by 16-bit multiplier, an on-chip timer, and a double-buffered serial port. Operation uses a single 5 V supply and is supported in 68-pin PGA and 68-lead PLCC packages.
