TC520A

Serial Interface Adapter for TC500 A/D Converter Family

Features

General Description

• Converts TC500/TC500A/TC510/TC514 to Serial

Operation

The TC520A serial interface adapter provides logic

control for Microchip's TC500/TC500A/TC510/TC514

family of dual slope, integrating A/D converters. It

directly manages TC500 converter phase control sig-

• Supports up to 17-Bits of Accuracy Plus Polarity Bit

• Low Power Operation: Typically 7.5mΩ

• 14-Pin PDIP or 16-Pin SOIC Packages

• Polled or Interrupt Mode Operation

processor task loading and software complexity. Com-

munication with the TC520A is accomplished over a 3

wire serial port. Key converter operating parameters

are programmable for complete user flexibility. Data

conversion is initiated when the CE input is brought

low. The converted data (plus overrange and polarity

bits) are held in an 18-bit shift register until read by the

processor or until the next conversion is completed.

Data may be clocked out of the TC520A at any time,

and at any rate, the user prefers. A Data Valid (DV) out-

put is driven active at the start of each conversion

cycle, indicating the 18-bit shift register update has just

been completed. This signal may be polled by the pro-

cessor or can be used as data ready interrupt. The

TC520A timebase can be derived from an external fre-

quency source of up to 6MHz or can operate from its

own external crystal. It requires a single 5V logic supply

and dissipates less than 7.5mΩ.

Applications

• Computer Peripheral Interface

• Portable Instruments

• Data Acquisition System Interface
