TC520ACOE

Specialized Overview

The TC520ACOE is a serial interface adapter designed for Microchip's TC500/TC500A/TC510/TC514 dual-slope integrating A/D converter family. It manages logic control signals (A, B, CMPTR) to reduce host processor task loading. The device operates on a single 5V supply with typical power dissipation of 7.5mW. It supports up to 17-bit accuracy plus a polarity bit and allows programmable conversion rates. Communication occurs via a 3-wire serial port, and the part is housed in a 16-pin SOIC package with an operating temperature range of 0°C to +70°C.

Specialized Feature Summary

• Converts TC500 series converters to serial operation
• Programmable conversion rate and resolution
• Supports up to 17-bits of accuracy plus polarity bit
• Low power operation

Specialized Applications

• Computer peripheral interface
• Portable instruments
• Data acquisition system interface

Specialized Procurement Notes

Verify the specific suffix 'COE' corresponds to the 16-pin SOIC wide package and the commercial temperature range (0°C to +70°C). Confirm that the component is sourced from authorized Microchip Technology distributors to ensure authenticity. Check for any recent product lifecycle notices or obsolescence warnings before finalizing procurement plans.

Specialized Selection Notes

Select this component when interfacing with TC500/TC500A/TC510/TC514 A/D converters to offload timing control from the main processor. Ensure the application requires a 16-pin SOIC package and operates within the 0°C to +70°C temperature range. Verify that the required resolution does not exceed 17 bits plus polarity.

Specialized Part Context

The TC520ACOE belongs to the TC520A family of serial interface adapters. It serves as a bridge between host processors and Microchip's precision analog front-end A/D converters, simplifying software complexity by handling phase sequencing and data shifting internally.

Specialized Replacement Considerations

The TC520ACP D variant offers identical functionality but utilizes a 14-pin PDIP package instead of the SOIC form factor. No other direct functional replacements are documented.
