SERIAL INTERFACE ADAPTER FOR TC500 A/D CONVERTER FAMILY  
FEATURES  
GENERAL DESCRIPTION  
■ Converts TC500/500A/510/514 to Serial Operation  
■ Programmable Conversion Rate and Resolution  
for Maximum Flexibility  
■ Supports up to 17 Bits of Accuracy Plus  
Polarity Bit  
■ Low Power Operation: Typically 7.5mW  
■ 14-Pin DIP or 16-Pin SOIC Packages  
■ Polled or Interrupt Mode Operation  
The TC520A Serial Interface Adapter provides logic  
control for TelCom's TC500/500A/510/514 family of dual  
slope,integratingA/Dconverters.ItdirectlymanagesTC500  
converter phase control signals A, B, and CMPTR thereby  
reducinghostprocessortaskloadingandsoftwarecomplex-  
ity. Communication with the TC520A is accomplished over  
a 3 wire serial port. Key converter operating parameters are  
programmable for complete user flexibility.  
Data conversion 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) output is driven active at the  
start of each conversion cycle indicating the 18 bit shift  
registerupdatehasjustbeencompleted. Thissignalmaybe  
polled by the processor, or can be used as data ready  
interrupt.

PIN CONFIGURATION  
The TC520A timebase can be derived from an external  
frequency source of up to 6MHz; or can operate from its own  
external crystal. It requires a single 5V logic supply and  
dissipates less than 7.5mW.
