Overview

The SCAMP II, Low-Power Notebook Chipset consists of the following chips:

• VL82C315A (SCAMP II, Low-Power Notebook Chipset)
• VL82C322A (PMU)
• VL82C325 (Cache controller)

The PMU and cache controller are optional, though you are unlikely to find a 315A without a 322A as these are intended for laptops. This entry is for the cached version. For the non-cached version see here.

The VL82C315A SCAMP II System Controller and the VL82C322A SCAMP Power Management Unit (PMU) provide a high-performance, low-chip count, low-power 16-bit notebook solution. These devices support fully-static AMB Am386 and Cyrix Cx486SLC microprocessors with System Management interrupt and 3.3 volt, 5.0 volt or mixed-mode operation.

The VL82C315A and the VL82C322A provide an excellent chip set solution for 386SX-based notebook systems operating up to 33 MHz.

The VL82C315A supports 387SX-compatible numeric coprocessors including versions that support slow and stop clock operation.

With VLSI's VL82C315A SCAMP I Controller, a system designer is assured a high-integration single chip that simplifies system design and lowers overall system cost, while the VL82C322A PMU reduces overall system power consumption.
