a. Stresses greater than those listed under Table 20: Absolute maximum ratings may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operating sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended period may effect reliability.
b. All I/O pins are 3.3 V tolerant except CLKIN, LPCLKIN, CLKOSC and LPCLKOSC


Description

The ST40RA is the first member of the ST40 family. Based on the SH-4, SuperH CPU core from SuperH Inc, the ST40RA is designed to work as a standalone device, or as part of a two chip solution for application specific systems.

Example applications the ST40RA is designed for include digital consumer, embedded communications, industrial and automotive. The high connectivity of the ST40 through its PCI bus and its dual memory uses makes it a versatile device, ideal for data-intensive and high performance applications.
