■ DESCRIPTION

The MB90595/595G series with FULL-CAN*1 interface 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

? 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
