M67201A/M67202A

Functional Description

Operating Modes

The M 67201A/202A is in a Single Device Configuration

when the Expansion In (XI) control input is grounded (see

Single Device Mode

A single M 67201A/202A may be used when the Figure 2). In this mode the Half-Full Flag (HF), which is

application requirements are for 512/1024 words or less. an active low output, is shared with Expansion Out (XO).

Status flags (EF, FF and HF) can be detected from any

device. Figure 3 demonstrates an 18-bit word width by

WIDTH EXPANSION MODE

Word width may be increased simply by connecting the using two M 67201A/202A. Any word width can be
