Spansion Analog and Microcontroller Products The following document contains information on Spansion analog and microcontroller products. Although the document is marked with the name Fujitsu, the company that originally developed the specification, Spansion will continue to offer these products to new and existing customers. Continuity of Specifications There is no change to this document as a result of offering the device as a Spansion product. Any changes that have been made are the result of normal document improvements and are noted in the document revision summary, where supported. Future routine revisions will occur when appropriate, and changes will be noted in a revision summary. Continuity of Ordering Part Numbers Spansion continues to support existing part numbers beginning with MB. To order these products, please use only the Ordering Part Numbers listed in this document. For More Information Please contact your local sales office for additional information about Spansion memory, analog, and microcontroller products and solutions. FUJITSU MICROELECTRONICS DS07-13703-7E DATA SHEET 16-bit Proprietary Microcontroller CMOS 2 F MC-16LX MB90540G/545G Series MB90F543G(S)/F546G(S)/F548G(S)/F549G(S)/549G(S)/V540G MB90543G(S)/547G(S)/548G(S)/F548GL(S) DESCRIPTION The MB90540G/545G series with FULL-CAN and Flash ROM is specially designed for automotive and industrial applications. Its main features are on-board CAN Interfaces (MB90540G series: 2 channels, MB90545G series: 1 channel) , which conform to CAN V2.0A and V2.0B specifications, supporting very flexible message buffer 2 scheme and so offering more functions than a normal full CAN approach. The instruction set by F MC-16LX CPU 2 core inherits an AT architecture of the F MC* family with additional instruction sets for high-level languages, extended addressing mode, enhanced multiplication/division instructions, and enhanced bit manipulation instruc- tions.The micro controller has a 32-bit accumulator for processing long word data.The MB90540G/545G series has peripheral resources of 8/10-bit A/D converters, UART (SCI) , extended I/O serial interfaces, 8/16-bit timer, I/O timer (input capture (ICU) , output compare (OCU) ) . 2 * : F MC is the abbreviation of FUJITSU Flexible Microcontroller. FEATURES Clock Embedded PLL clock multiplication circuit Operating clock (PLL clock) can be selected from : divided-by-2 of oscillation or one to four times the oscillation Minimum instruction execution time : 62.5 ns (operation at oscillation of 4 MHz, PLL four times multiplied : machine clock 16 MHz and at operating VCC = 5.0 V) Subsystem Clock : 32 kHz Instruction set to optimize controller applications Rich data types (bit, byte, word, long word) Rich addressing mode (23 types) Enhanced signed multiplication/division instruction and RETI instruction functions Enhanced precision calculation realized by the 32-bit accumulator (Continued) For the information for microcontroller supports, see the following web site.
