SX User’s Manual Rev. 3.1 16 © 2000 Scenix Semiconductor, Inc. All rights reserved. www.scenix.com Chapter 1 Overview The SX48/52BD devices are available in the pin configurations shown in Figure 1-2. These devices
are functionally the same except that the 48-pin device does not have the port pins RA4 through RA7.
Therefore, the upper four pins of Port A are not available in the smaller package. Figure 1-2 SX48/52BD Pin Assignments Top View 36
