Rad. Tolerant High Speed 16 Kb x 9 Parallel FIFO with Programmable Flag

Atmel Corporation 

Functional Description

Single Device Mode

A single M672061H may be used when the application requirements are for 16384

words or less. The M672061H is in a Single Device Configuration when the Expansion In (XI)

control input is grounded (see Figure 3). In this mode the Half-Full Flag (HF), which is an active

low output, is shared with Expansion Out (XO).

Width Expansion Mode

Word width may be increased simply by connecting the corresponding input control sig-

nals of multiple devices. Status flags (EF, FF and HF) can be detected from any device.

Figure 4 demonstrates an 18-bit word width by using two M672061H. Any word width can be

attained by adding additional M672061H.

Note: Flag detection is accomplished by monitoring the FF, EF and the HF signals on either (any) device used in the width expansion

configuration. Do not connect any output control signals together.
