ADSP-TS101SAB1Z100

Digital Signal Processor Dsp Overview

The ADSP-TS101SAB1Z100 is a TigerSHARC static superscalar digital signal processor operating at a maximum clock frequency of 300 MHz with a 3.3 ns instruction cycle time. It features 6 Mbits of on-chip SRAM memory organized into three 2M-bit blocks (64K words × 32 bits). The core architecture includes dual computation blocks, each containing an ALU, multiplier, shifter, and register file, alongside dual integer ALUs for data addressing. The device supports 32- and 40-bit floating-point and 8-, 16-, 32-, and 64-bit fixed-point processing. It is housed in a 27 mm × 27 mm 625-ball PBGA package.

Digital Signal Processor Dsp Feature Summary

• Dual compute blocks enabling up to four instructions per cycle, delivering 1,800 MFLOPS or 7.3 GOPS performance.
• Integrated 6 Mbit SRAM providing 14.4 Gbytes/second internal memory bandwidth via three independent 128-bit buses.
• On-chip arbitration supporting glueless multiprocessing systems with up to eight TigerSHARC processors.
• Comprehensive I/O including a 14-channel DMA controller, external port, four link ports, and SDRAM controller.

Digital Signal Processor Dsp Applications

• Telecommunications infrastructure requiring high-performance DSP operations.
• Large-scale multiprocessor DSP applications demanding low communication overhead.
• Real-time signal processing tasks optimized for static superscalar execution.

Digital Signal Processor Dsp Procurement Notes

Verify the specific package variant against project requirements, as the ADSP-TS101S series is available in both 484-ball CSP_BGA and 625-ball PBGA configurations. Confirm that the AB1 suffix corresponds to the intended speed grade and pinout compatibility. Ensure supply chain sources provide valid documentation matching the Rev. E datasheet specifications.

Digital Signal Processor Dsp Selection Notes

Select this component when system design requires high throughput for complex algorithms such as FFTs or FIR filters. The 300 MHz speed grade offers 2.4 billion 40-bit MACs per second. Consider the 625-ball PBGA package if higher pin density is needed for extensive external memory interfaces compared to the 484-ball option.

Digital Signal Processor Dsp Part Context

This part belongs to the ADSP-TS101S family within the TigerSHARC embedded processor line. It is code-compatible with other TigerSHARC processors, facilitating migration from legacy designs. The AB1Z100 designation identifies the specific speed bin and packaging configuration for this 300 MHz unit.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the same family include the ADSP-TS101SAB2Z100, which utilizes a 484-ball CSP_BGA package but shares identical core specifications and functionality.
