www.DataSheet4U.com FUJITSU SEMICONDUCTOR DATA SHEET DS07-16502-3E 32-Bit Proprietary Microcontroller CMOS FR60 MB91301 Series MB91302A/V301A ■ 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. ■ FEATURES The MB91301 series is a line of ICs with various programs embedded in internal ROM.
