Description and Introduction

Enhanced SCAN bridge Multidrop Addressable IEEE 1149.1 (JTAG) Port The SCANSTA111SM is a Scan Test Aggregator (STA) manufactured by National Semiconductor (NSC).  

### **Key Specifications:**  
- **Manufacturer:** National Semiconductor (NSC)  
- **Type:** Scan Test Aggregator (STA)  
- **Function:** Facilitates IEEE 1149.1 (JTAG) boundary scan testing for multiple devices.  
- **Features:**  
  - Supports up to 7 independent scan chains.  
  - Allows parallel or serial scan chain configurations.  
  - Provides multiplexing of test data input (TDI) and test data output (TDO).  
  - Includes programmable scan chain selection.  
  - Compatible with IEEE 1149.1 standard.  

### **Descriptions and Features:**  
- Enables efficient testing of complex PCBs by managing multiple JTAG scan chains.  
- Reduces test time by allowing parallel testing of multiple scan chains.  
- Programmable scan chain selection provides flexibility in test configurations.  
- Designed for high-speed boundary scan applications.

Application Scenarios & Design Considerations

Enhanced SCAN bridge Multidrop Addressable IEEE 1149.1 (JTAG) Port

Alternative Part Number

  • DS90CR286AMTD --: TI acquired National Semiconductor, so this is a same-vendor-family LVDS interface device with similar signaling role and readily available support.
  • SN65LVDS386DGG --: LVDS receiver/interface IC from the TI portfolio that can serve similar board-level interconnect functions with comparable supply and package options.
  • MAX9206EAI+ --: Independent LVDS deserializer/interface alternative with similar high-speed differential signaling capability for designs needing a second source.
  • SCANSTA111MTD --: Same SCANSTA111 function from the current TI portfolio in a different package option, electrically compatible with the SM variant.
  • SCANSTA111TM --: TI-branded equivalent of the SCANSTA111 boundary-scan device, suitable drop-in replacement for National Semiconductor parts.
  • SCANSTA112SM --: Closely related SCANSTA112 family member with similar boundary-scan multiplexer functionality, usable when minor feature differences are acceptable.
