■ DESCRIPTION

The MB90350E series, loaded 1 channel FULL-CAN* interface and Flash ROM, is general-purpose FUJITSU MICROELECTRONICS 16-bit microcontroller designing for automotive and industrial applications. Its main feature is the on-board CAN interface, which conforms to CAN standard Version2.0 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

? Built-in PLL clock frequency multiplication circuit

? Selection of machine clocks (PLL clocks) is allowed among frequency division by two on oscillation clock, and multiplication of 1 to 6 times of oscillation clock (for 4 MHz oscillation clock, 4 MHz to 24 MHz).

? Operation by sub clock (up to 50 kHz : 100 kHz oscillation clock divided by two) is allowed (devices without S-suffix only) .

? Minimum execution time of instruction : 42 ns (when operating with 4-MHz oscillation clock, and 6-time multiplied PLL clock).

? Built-in clock modulation circuit

? 16 Mbytes CPU memory space

24-bit internal addressing

? Instruction system best suited to controller

? Wide choice of data types (bit, byte, word, and long word)

? Wide choice of addressing modes (23 types)

? Enhanced multiply-divide instructions with sign and RETI instructions

? Clock supervisor (MB90x356x and MB90x357x only)

Main clock or sub clock is monitored independently.

? Enhanced high-precision computing with 32-bit accumulator

? Instruction system compatible with high-level language (C language) and multitask

? Employing system stack pointer

? Enhanced various pointer indirect instructions

? Barrel shift instructions

? Increased processing speed

4-byte instruction queue

? Powerful interrupt function

? Powerful 8-level, 34-condition interrupt feature

? Up to 8 channels external interrupts are supported.

? Automatic data transfer function independent of CPU

? Extended intelligent I/O service function (EI2OS) : up to 16 channels

? DMA : up to 16 channels

? Low power consumption (standby) mode

? Sleep mode (a mode that stops CPU operating clock)

? Main timer mode (a timebase timer mode switched from the main clock mode)

? PLL timer mode (a timebase timer mode switched from the PLL clock mode)

? Watch mode (a mode that operates sub clock and watch timer only)

? Stop mode (a mode that stops oscillation clock and sub clock)

? CPU intermittent operation mode

? Process

CMOS technology

? I/O port

? General-purpose input/output port (CMOS output)

- 49 ports (devices without S-suffix : devices that correspond to sub clock)

- 51 ports (devices with S-suffix : devices that do not correspond to sub clock)
