TP3465V

Specialized Overview

The TP3465V is a MICROWIRE Interface Device (MID) manufactured by Texas Instruments, designed to enable microprocessors to communicate with up to eight peripheral devices via the serial MICROWIRE interface. It maps peripherals as memory locations by handling data serialization and protocols. The device supports both multiplexed and non-multiplexed bus formats compatible with National/Intel and Motorola architectures. It features a programmable clock divider for SK rates up to 5 MHz derived from a CKIN input of up to 20 MHz. The component operates in commercial temperature ranges and is housed in a 28-pin PLCC package.

Specialized Feature Summary

• Supports multiplexed and non-multiplexed microprocessor bus interfaces compatible with National/Intel and Motorola formats
• Provides hardware-assisted chip select generation for up to eight MICROWIRE peripherals
• Configurable as a MICROWIRE bus master or slave with programmable clock polarity and mode settings
• Includes dedicated control registers for pin definition, clock rate division, and status monitoring

Specialized Applications

• ISDN terminal adapters interfacing with ISDN components and non-ISDN peripherals
• Digital and analog linecards utilizing COMBO devices or serial EEPROMs
• Interfacing standard microprocessors to industry serial EEPROMs and LCD drivers

Specialized Procurement Notes

Verify the specific ordering suffix 'V' corresponds to the 28-pin PLCC package configuration as documented in the datasheet. Confirm that the intended application environment remains within the specified commercial temperature range. Ensure compatibility with the target microprocessor's bus protocol requirements before integration.

Specialized Selection Notes

Select this component when a host processor requires expansion of serial peripheral connectivity without complex software overhead. It is suitable for systems needing memory-mapped access to multiple MICROWIRE devices. Consider the available address lines and control signals required by the chosen bus format during system design.

Specialized Part Context

This device belongs to the MICROWIRE Interface Device family, originally developed by National Semiconductor. It serves as a bridge between parallel microprocessor buses and serial MICROWIRE peripherals. The TP3465 simplifies system architecture by reducing pin count requirements for connecting multiple serial devices to a central processing unit.
