The SMS8198 is a precision supervisory circuit designed specifically as a companion chip for the Philips TriMedia Processor family. The SMS8198 monitors the power supply and holds the system in reset whenever VCC is below the VTRIP threshold.

In addition to the supervisory function, the SMS8198 has 16K-bits of nonvolatile memory that is used by the TriMedia processor as the boot memory.

The SMS8198 provides 16K-bits of memory that is accessible through the industry standard 2-wire serial interface. By integrating a precision supervisory circuit and th hardware WP input, the SMS8198 becomes the perfect companion chip for the Philips TriMedia processor family. Its functions are integral to the boot hardware operation of the TriMedia processors.
