| AMENDMENT AM29030TM and Am29035 TM RISC Microprocessors with 8-Kbyte/4-Kbyte Instruction Cache Advanced Micro Devices This amendment adds preliminary information on switching characteristics over commercial operating ranges for the 25-MHz AM29030TM microprocessor. ORDERING INFORMATION Standard Products AMD standard products are available in several packages and operating ranges. Valid order numbers are formed by a combination of the elements below. AM29030 -25 F C /W SHIPPING OPTION Blank = For PGA package only /W = For Cerquad package only: denotes leads are trimmed/formed TEMPERATURE RANGE C = Commercial (TC = 0C to +85C) PACKAGE TYPE F = 144-Lead Cerquad (GQD144) G = 145-Lead Pin Grid Array without Heat Sink (CGY145) SPEED OPTION -33 = 33 MHz -25 = 25 MHz -20 = 20 MHz -16 = 16 MHz DEVICE NUMBER/DESCRIPTION AM29030 RISC Microprocessor with 8 Kbyte of Instruction Cache Am29035TM RISC Microprocessor with 4 Kbyte of Instruction Cache Valid Combinations AM29030-33 AM29030-25 AM29030-25 AM29030-20 AM29035-16 GC Valid Combinations Valid Combinations list configurations planned to be supported in volume. Consult the local AMD sales office to confirm availability of specific valid combinations, and check on newly released combinations. FC/W This document contains information on a product under development at Advanced Micro Devices, Inc. The information is intended to help you to evaluate this product. AMD reserves the right to change or discontinue work on this proposed product without notice. Publication# 18150 Rev. A Amendment /1 Issue Date: December 1993.

MEMCLK as an input is always CMOS level. 2. MEMCLK can drive an external load of 150 pF. 3. The input setup times with MEMCLK used as an input are improved if MEMCLK and INCLK are tied to the same clock input. This is possible only if the processor and bus operate at the same frequency. 4. Except where noted, measurement conditions are the same as the Am29000 microprocessor. 5. All output valid delays are measured with VOL = 1.5 V and VOH = 1.5 V.
