RADIATION HARDENED
32-BIT MICROPROCESSOR
80486DX2RP
FEATURES:
32-Bit Microprocessor Total Dose Hardness: typical Krad (Si); dependent upon orbit Single Event Effect SELTH 59.6 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' 80486DX2RP RAD-PAK®) high-performance 32-bit microprocessor features typical 100krad (Si) total dose tolerance. 80486DX2RP processor integrates unified cache floating-point (FPU) hardware-onchip. on-chip memory management unit completely compatible with 80386 processor. on-chip cache memory allows frequently used data code stored on-chip, reducing accesses external bus. speed-multiplying technology, allowing processor operate frequencies higher than external memory bus. clock multiplier 80486DX2RP improves execution performance without increasing board design complexity. enhances operations operating cache and/or blocked external accesses. burst feature enables fast cache fills. patented radiationhardened 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 in-space environment, 80486DX2RP ideal satellite, spacecraft, space probe missions. available Class packaging screening.

This parameter proper power supply selection. measured using worst case instruction 5.25V. maximum current column thermal design power dissipation. measured using worst case instruction typical current column typical operating current system. This value measured system using typical device 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. 80486DX2RP ELECTRICAL CHARACTERISTICS (VCC=5V 10%, +125 unless otherwise specified) PARAMETER TEST CONDITION SYMBOL Operating Frequency 80486DX2RP-50 80486DX2RP-66 Frequency 80486DX2RP-50 80486DX2RP-66 Period 80486DX2RP-50 80486DX2RP-66 Period Stability 80486DX2RP-50 +250 +250 80486DX2RP-66 High Time 80486DX2RP-50 80486DX2RP-66 CLK2 Time 0.8V 80486DX2RP-50 80486DX2RP-66 Fall Time 0.8V 80486DX2RP-50 80486DX2RP-66 CLK2 Rise Time 0.8V 80486DX2RP-50 80486DX2RP-66 A31, PWT, PCD, BE0-3#, M/IO#, D/C#, W/R#, ADS#, LOCK#, BREQ, HLDA, SMIACT#, FERR# Valid Delay 80486DX2RP-50 80486DX2RP-66 A31, PWT, PCD, BE0-3#, M/IO#, D/C#, W/R#, ADS#, LOCK#, BREQ, HLDA, Float Delay 80486DX2RP-50 80486DX2RP-66
