It is designed for very high performance and multitasking operating systems. The integrated memory management and protection architecture includes address translation registers, multitasking hardware and a protection mechanism to support operating systems. The 80386DX allows simultaneous running of multiple operations. In addition, the 80386DX is capable of execution at sustained rates of between 3 and 4 million instructions per second. It offers new testability and debugging features, including a self-test and direct access to the page translation cache. Maxwell Technologies' patented RAD-PAK® packaging technology incorporates radiation shielding in the microcircuit package. It eliminates the need for box shielding while providing the required radiation shielding for a lifetime in orbit or space mission. In a GEO orbit, RAD-PAK provides greater than 100 krad (Si) radiation dose tolerance. This product is available with screening up to Class S. 1000557 12.17.01 Rev1 All data sheets are subject to change without notice 1 (858) 503-3300 - Fax: (858) 503-3301 - www.maxwell.com ©2001 Maxwell Technologies All rights reserved. 32-Bit Microprocessor TABLE 1. 80386DX PIN DESCRIPTION PIN 1-7, 9, 10, 12, 13, 16, 17, 20, 21, 24, 146-149, 152-154, 156159, 161-163 8, 18, 19, 22, 23, 25, 28-30, 33, 36, 38-40, 47, 48, 65, 66, 68, 73, 76, 77, 82, 84, 86, 88, 103, 106, 107, 114, 125, 126, 129, 130,133, 134, 145, 155, 160, 164 11, 15, 27, 32, 35, 43, 51, 53, 55, 57, 61, 70, 92, 95, 100, 111, 118, 122, 138, 142, 151 14, 26, 31, 34, 44, 50, 52, 54, 56, 58, 62, 69, 91, 96, 99, 110, 117, 137, 141, 150, 37 41 42 45 46 49 59 60 63 64 67, 71, 72, 74 78 75 79 80 81 83 85, 87, 89, 90, 93, 94, 97, 98, 102, 104, 105, 108, 109, 112, 113, 115, 116, 119, 120, 121, 123, 124, 127, 128, 131, 132, 135, 136, 139, 140, 143, 144, 101 SYMBOL A16-A11, A9, A10, A7, A8, A5, A6, Address Bus A3, A4, A2, A31-A28, A27-A25, A23-A22, A20-A18 NC Not Connected DESCRIPTION 80386DX VSS Ground VCC Power Supply Memory INTR NMI PEREQ ERROR RESET BUSY LOCK W/R M/IO D/C BE2, BE0, BE3, BE1 BS16 NA HOLD CLK2 ADS READY Interupt Request Non-Maskable Interupt Request Processor Extension Request Error Status Reset Busy Status Bus Lock Write/ Read Memory I/O Data Control Byte Enables Bus Size 16 Next Address Bus Hold Request CPU Clock 2 Address Staus Bus Ready Input D1, D2, D4, D0, D6, D3, D8, D5, D7, Data Bus D10, D9, D12, D11, D14, D13, D15, D16, D18, D17, D20, D22, D19, D24, D21, D25,D23, D27, D26, D29, D28, D31, D30, HLDA Bus Hold Acknowledge 1000557 12.17.01 Rev1 All data sheets are subject to change without notice 2 ©2001 Maxwell Technologies All rights reserved. 32-Bit Microprocessor TABLE 2. 80386DX ABSOLUTE MAXIMUM RATINGS PARAMETER Supply Voltage with Respect to Ground Voltage on other pins Thermal Impedance Operating Temperature Range (Ambient) Storage Temperature Range (Ambient) SYMBOL VSS MIN -0.5 -0.5 --55 -6...
