The Am29112 is a high‑performance 8‑bit slice microprogram sequencer designed for use in single‑level pipelined systems. It can be cascaded to form a 16‑bit device and includes features such as maskable and unmaskable interrupts, a 33‑deep on‑chip stack, and a high‑speed adder with full carry look‑ahead across 8 bits.
