AMD AM486DX5
The Enhanced Am486®DX Microprocessor Family is an hanced Am486DX microprocessor family. This results in addition to the AMD E86 family of embedded micropro- decreased development costs and improved time to mar- cessors.FEATURES
- 3-V core with 5-V tolerant I/O - Wide range of chipsets and support available through the AMD FusionE86SM Program s 168-Pin PGA Package or 208-Pin SQFP Package s IEEE 1149.1 JTAG Boundary-Scan CompatibilityGENERAL DESCRIPTION
This new family enhances system performance ket. by incorporating a 16-Kbyte write-back cache to the existing flexible clock control and enhanced SMM features of a 486 CPU. Table 1 shows available processors in the Enhanced Am486DX microprocessor family. See page 54 for information on how these parts differ from other Am486 The Enhanced Am486DX microprocessor family en- processors. ables write-back configuration through software and cacheable access control. On-chip cache lines are con- figurable as either write-through or write-back. The CPU clock control feature permits the CPU clock to be stopped Table 1.
