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. s Memory protection and VM system support q q 64-entry unified TLB, 4-entry instruction TLB 4 Gbytes address space s Standard ST40 peripherals q q 2 synchronous serial ports with FIFO (SCIF) Timers and a real-time clock IO devices q q Mailbox register for interprocessor communication Additional PIO System features s 32-bit SuperH CPU q q q q q Bus interfaces s Local memory interface SDRAM & DDR SDRAM q 64-bit hardware FPU (1.16 GFLOPS) 128-bit vector unit for matrix manipulations 166 MHz, 300 MIPS (DMIPS 1.1) Up to 664 M……
