32-Bit Proprietary Microcontroller
CMOS
FR60 MB91301 Series
MB91302A/V301A
DS07-16502-3E
■ DESCRIPTION
The MB91301 series are a line of microcontrollers based on a 32-bit RISC CPU core (FR family) , incorporating
a variety of I/O resources and a bus control mechanism for embedded control that requires the processing of a
high-performance, fast CPU as well as an SDRAM interface that can connect SDRAM directly to the chip.
The large address space supported by the 32-bit CPU addressing means that operation is primarily based on
external bus access although instruction cache memory of 4 Kbytes and RAM of 4 Kbytes( for data) are included
for high-speed execution of CPU instructions.
The MB91302A and MB91V301A are FR60 products based on the FR30/40 CPU with enhanced bus access for
higher speed operation. The device specifications include a D/A converter to facilitate motor control and are ideal
for use in DVD players that support fly-by transfer.
