资 源 简 介

The 83C51KB is an application specific read-onlymemory(ROM) microcontroller. The 83C51KB isdesigned as a keyboard scanner and is architecturallysimilar but not identical to the 80C51BH.Certain features not on the 80C51 have been addedto support keyboard scanning. In order tostreamline 83C51KB cost/performance factors,80C51 peripherals not applicable to keyboardscanning are no longer present.Refer to the MCS® 51 Microcontroller Family User’s Manual(order number 272383) for a complete descriptionof the 80C51. Figure 1 contains a basic memorymap of the architecture. 83C51KB electrical informationis contained in the datasheet (order number272800).
