MB90F594A Descrizione generale

■ DESCRIPTIONThe MB90590/590G series with two FULL-CAN*1 interfaces and FLASH ROM is especially designed for automotive and industrial applications. Its main features are two on board CAN Interfaces, which conform to V2.0 Part A and Part B, while supporting a very flexible message buffer scheme and so offering more functions than a normal full CAN approach.■ FEATURES• ClockEmbedded PLL clock multiplication circuitOperating clock (PLL clock) can be selected from divided-by-2 of oscillation or one to four times the oscillation (at oscillation of 4 MHz, 4 MHz to 16 MHz).Minimum instruction execution time : 62.5 ns (operation at oscillation of 4 MHz, four times the oscillation clock, VCC of 5.0 V)• 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• Instruction set designed for high level language (C language) and multi-task operations   Adoption of system stack pointer   Enhanced pointer indirect instructions   Barrel shift instructions• Program patch function (for two address pointers)• Enhanced execution speed : 4-byte instruction queue• Enhanced interrupt function : 8 levels, 34 factors• Automatic data transmission function independent of CPU operation   Extended intelligent I/O service function (EI2OS) : Up to 10 channels• Embedded ROM size and types   Mask ROM : 256 Kbytes/384 Kbytes   Flash ROM : 256 Kbytes/384 Kbytes   Embedded RAM size : 6 Kbytes/8 Kbytes• Flash ROM   Supports automatic programming, Embedded Algorithm TM*   Write/Erase/Erase-Suspend/Resume commands   A flag indicating completion of the algorithm   Hard-wired reset vector available in order to point to a fixed boot sector in Flash Memory   Erase can be performed on each block   Block protection with external programming voltage• Low-power consumption (stand-by) mode   Sleep mode (mode in which CPU operating clock is stopped)   Stop mode (mode in which oscillation is stopped)   CPU intermittent operation mode   Clock mode   Hardware stand-by mode• Process   0.5µm CMOS technology• I/O port   General-purpose I/O ports : 78 ports• Timer   Watchdog timer : 1 channel   8/16-bit PPG timer : 8/16-bit × 6 channels   16-bit re-load timer : 2 channels
