The ADSP-TS101S TigerSHARC®processor is an ultrahigh performance, Static Superscalar™processor optimized for large signal processing tasks and communications infrastructure. The DSP combines very wide memory widths with dual computation blocks—supporting 32- and 40-bit floating-point and 8-, 16-, 32-, and 64-bit fixed-point processing—to set a new standard of performance for digital signal processors. The TigerSHARC processor’s Static Superscalar architecture lets the processor execute up to four instructions each cycle, performing 24 fixed-point (16-bit) operations or six floating-point operations.Three independent 128-bit-wide internal data buses, each connecting to one of the three 2M bit memory banks, enable quad word data, instruction, and I/O accesses and provide 14.4G bytes per second of internal memory bandwidth. Operating at 300 MHz, the ADSP-TS101S processor’s core has a 3.3 ns instruction cycle time. Using its single-instruction, multiple-data (SIMD) features, the ADSP-TS101S can perform 2.4 billion 40-bit MACs or 600 million 80-bit MACs per second. Table 1 and Table 2 in the data sheet show the DSP’s performance benchmarks.

The ADT6401/ADT6402 are trip point temperature switches available in a 6-lead SOT-23 package. Each part contains an internal band gap temperature sensor for local temperature sensing. When the temperature crosses the trip point setting, the logic output is activated. The ADT6401 logic output is active low and open-drain. The ADT6402 logic output is active high and push-pull. The temperature is digitized to a resolution of 0.125°C (11-bit). The pin-selectable trip point settings are 10°C apart starting from −45°C to +5°C for undertemperature switching, and from 45°C to 115°C for overtemperature switching.These devices typically consume 30 μA of supply current. Hysteresis is pin selectable at 2°C and 10°C. The temperature switch is specified to operate over the supply range of 2.7 V to 5.5 V.When the ADT6401/ADT6402 are used for monitoring tempera- tures from 45°C to 115°C, the logic output pin becomes active when the temperature goes higher than the selected trip point temperature. When the ADT6401/ADT6402 are used for monitoring tempera- tures from −45°C to +5°C, the logic output pin becomes active when the temperature goes lower than the selected trip point temperature.Product HighlightsΣ-Δ based temperature measurement gives high accuracy and noise immunity.Wide operating temperature range from −55°C to +125°C.±0.5°C typical accuracy from −45°C to +115°C.Pin-selectable threshold settings from −45°C to +115°C in 10°C increments.Supply voltage is 2.7 V to 5.5 V.Supply current of 30 μA.Space-saving, 6-lead SOT-23 package.Pin-selectable temperature hysteresis of 2°C or 10°C.Temperature resolution of 0.125°C.ApplicationsMedical equipmentAutomotive Cell phones Hard disk drivesPersonal computersElectronic test equipmentDomestic appliancesProcess controlData Sheet, Rev. 0, 5/08
