TP3465 Datasheet | National Semiconductor

Description The MICROWIRETM Interface Device MID gives a general microprocessor (such as National Series 32000 processors Intel 80C188 80C86 or 80286 Motorola 6800 and 68000 family of processors) the ability to municate efficiently with up to eight peripheral devices via the serial MICROWIRE interface The MID causes each of the peripheral devices to appear to the m P as memory mapped locations by performing all the data serialization and transfer protocols to and from the peripherals Features Applications Y Y Y Y Y ISDN Terminal Adapters Digital Line cards (ISDN and Non ISDN) Analog Linecards using National BO Interfacing to industry standard serial EEPROMs Interfacing to industry standard MICROWIRE peripheral devices such as Analog to Digital Converters LCD drivers clock generators Multiplexed and Non-multiplexed microprocessor bus patible National Intel and Motorola microprocessor bus patible Microprocessor Clock (CKIN) up to 20 MHz MICROWIRE clock speeds up to 5 MHz Directly patible with 8- and 16-bit MICROWIRE peripherals mercial temperature range 0C to +70C TP3465 for 8 Chip Select output Memory mapped peripherals Programmable MICROWIRE Clock to municate with devices of different speeds Operates as MICROWIRE bus master or slave 28-pin PLCC Package CMOS Low Power Block Diagram TL H 10803 - 1 FIGURE 1 MICROWIRE Interface Device MID BO Series 32000 and TRI-STATE are registered trademarks of National Semiconductor Corporation MICROWIRETM is a trademark of National Semiconductor Corporation C1999 National Semiconductor Corporation TL H 10803 Connection Diagrams 28-Pin PLCC TL H 10803 - 3 Top View Order Number TP3465V See NS Package Number V28A FIGURE 2.
