Data Access Register

General Description

Features

High-speedÐgreater than

rate

30 MHz microinstruction

The ’F407 Data Access Register (DAR) performs memory

address arithmetic for RAM resident stack applications. It

contains three 4-bit registers intended for Program Counter

(R ), Stack Pointer (R ), and Operand Address (R ). The

Three 4-bit registers

16 instructions for register manipulation

Two separate output ports, one transparent

Relative addressing capability

TRI-STATE Outputs

’F407 implements 16 instructions which allow either pre- or

post-decrement/increment and register-to-register transfer

in a single clock cycle. It is expandable in 4-bit increments

and can operate at a 30 MHz microinstruction rate on a

Optional pre- or post- arithmetic

Expandable in multiples of four bits

16-bit word. The TRI-STATE outputs are provided for bus-

oriented applications. The ’F407 is fully compatible with all

TTL families.
