SST
Digital Signal Processors

Utilizing the HardSIL™ technology from SST, commercial Digital Signal Processors (DSPs) from Texas Instruments have been converted to higher performance hardened devices.

Existing DSPs produced by Texas Instruments have been manufactured, without redesign, to improve:
  • Total Ionizing Dose
  • SEL Immunity
  • Single Event Effects
HardSIL™ allows systems designers to use existing TI commercial DSP components for signal development in new platforms. For system products that will operate in harsh environments, the most susceptible components can be swapped with HardSIL™ components with no adverse effects to the electrical performance. HardSIL™ components have the same electrical performance, power, package size, and pinout configuration as the commercial version.

SST is partnering with Texas Instruments in developing hardened versions of TI catalog parts, current examples are:
  • TMS320C6701
  • TMS320VC33
  • TMS320C6727B

8Mb Dual Port
Synch. RH-SRAM

C035HS512K16 - 8Mb Dual Port Synchronous RH-SRAM (preliminary)

C035HS512K16 is a high performance, synchronous Dual Port 8Mb RH-SRAM organized as 524,288 words by 16 bits. It is pin selectable: master or slave. The master device is a full function device with user defined autonomous EDAC and scrub options. The slave device employs a scrub on demand feature that can be initiated by a master device. The C035HS512K16 is manufactured by Texas Instruments using HardSIL™ technology from SST.

Features
  • Access time: <20ns flow through mode, <10ns pipeline mode
  • Selectable between flow through and pipeline modes
  • Built-in Error Detection and Correction (EDAC) to mitigate soft errors
  • Built-in scrub engine for autonomous correction
  • Built-in address counter for sequential memory access with repeat feature
  • Dual chip enable allows for depth and width expansion without additional logic
  • Asynchronous output enable for each port
  • Support various clock modes and stress test modes
  • CMOS compatible input and output level, three state bidirectional data bus
  • 3.3 +/- 0.3V I/O, 1.5 +/- 0.15V CORE
  • Packaging options: 128-lead ceramic quad flatpack (CQFP128)
Radiation Performance (expected)
  • TID immunity: >300krad (Si)
  • SER: <5e-17 upsets/bit-day (core using ECC and Scrub) calculated using CREME96 for geosynchronous orbit, solar minimum
  • Latch-up immunity: >LET 110 MeV (T=398K)
