80486DX4RP
FEATURES:
32-Bit Microprocessor Total Dose Hardness: typical Krad (Si); dependent upon orbit Single Event Effect SELTH MeV/mg/cm2 SEUTH MeV/mg/cm2 Package: RAD-PAK® Quad Flat Pack 8-Kilobyte On-Chip Cache with Consistency Support External Cache Controller Integrated Floating-Point Unit Single Cycle Execution 32-Bit RISC Integer Core Instruction Pipelining On-Chip Management Unit Write Buffers Backoff Instruction Restart Chip Floating Point Unit
DESCRIPTION:
Space Electronics' 80486DX4RP RAD-PAK®) high-performance 32-bit microprocessor features typical 100krad (Si) total dose tolerance. 80486DX4RP processor integrates unified cache floating-point (FPU) hardware-on-chip. on-chip memory management unit completely compatible with 80386 processor. 16-kilobyte on-chip cache memory allows storing frequently used data code on-chip, reducing accesses external bus. speed-multiplying technology allows processor operate frequencies higher than external memory bus. clock multiplier 80486DX4RP improves execution performance without increasing board design complexity Write-Back Enhanced processors capable using onchip write-back cache policy. enhances operations operating cache and/or blocked external accesses. burst feature enables fast cache fills. patented radiation-hardened RAD-PAK® technology incorporates radiation shielding microcircuit package. provides krad better (Si) total dose survivability, based GEO-type orbit. Actual tolerance dependent upon orbit mission duration. Capable surviving space environment, 80486DX4 ideal satellite, spacecraft, space probe missions. available Class packaging screening.

Notes: This parameter inputs with pull-downs 2.4V. This parameter inputs with pull-ups 0.4V. When processor Stop Grant state, ICCU host processor less than 100% tested. This parameter inputs with pull-downs 2.4V. (SRESET only). This parameter proper power supply selection. measured using worst case instruction 3.6V. maximum current column thermal design power dissipation. measured using worst case instruction 3.3V. typical current column typical operating current system. This value measured system using typical device 3.3V, running Microsoft Windows idle condition. This typical value dependent upon specific system configuration. Stop Grant specification refers value once processor enters Stop Grant Auto HALT Power Down state. Stop Clock specification refers value once processor enters Stop Clock state. levels must equal respectively, order meet Stop Clock specifications.
