■ DESCRIPTION
The MB90590/590G series with two FULL-CAN*1 interfaces and FLASH ROM is especially designed for automo
tive 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
• 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 (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
