MB88305, MB88304 Datasheet - Fujitsu

MB88305 NMOS Input / Output Expander

The MB 88304/88305 have two interfaces: One is the processor interface; C$, LDI, and DI3-DI0, which are used for the processor to communicate with the MB 88304/5 devices. Another is the expansion I/O ports; Ports A, B, C, and D, which serve as an expansion of the processor's I/O. Table 1 - PIN DES.

Besides furnishing simple I/O port expansion, the MB 88304 and MB 88305 can AND or OR port data with data from the MCU, on instruction from the MCU. The MB 88304/MB 88305 are pseudo-bi.

MB88305 Features

* Four 4-bit I/O ports (16 lines)

* Four Functions: parallel input, parallel output, AND output, and OR output

* AND and OR functions provide individual output capability

* Single-bit input/output: Input and output can be intermixed on each port

* High output
