s DESCRIPTION
The MB86830 series is a SPARClite *¹ series of RISC architecture processors, providing high performance for a
variety of embedded applications. Conforming to the SPARC *² architecture, the MB86830 series is upward code-
compatible with the conventional products in the SPARClite family. When running at 100 MHz, the MB86830 series
provides performance of 121 VAX-MIPS.
The MB86830 series has on-chip data and instruction caches, allowing the processor to operate independently of
the wait time for external memory. The independent instruction bus and internal data bus serve as high-bandwidth
interfaces between the IU (integer unit) and caches. The MB86830 series also contains an internal multiplier circuit
that facilitates interfacing with external devices, thereby providing high performance with continuous cache hits. The
DRAM controller supports both of EDO and fast-page mode DRAMs. The interrupt controller (IRC) supports eight
channels of interrupts, allowing a trigger mode and mask to be set for each of the channels. To get the most out of
the system with a minimum number of external circuits, the MB86830 series supports chip select output, program-
mable wait state generator, and page mode DRAM interfaces.
The combination of these features of the MB86830 series achieves high levels of speed, flexibility, and efficiency,
making it a line of ideal controllers for a variety of low-cost, high-performance embedded systems.
