■ DESCRIPTION The MB90340E series with up to 2 FULL-CAN interfaces is especially designed for automotive and other industrial applications. Its main feature are the 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. The power to the MCU core (3 V) is supplied by a built-in regulator circuit, giving these microcontrollers superior performance in terms of power consumption and tolerance to EMI. ■ FEATURES • CPU • 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 functionality with signed multiply and divide instructions and the RETI instruction - Enhanced high-precision computing with 32-bit accumulator • Instruction system compatible with high-level language (C language) and multitask - Employing system stack pointer - Various enhanced pointer indirect instructions - Barrel shift instructions • Increased processing speed - 4-byte instruction queue • Serial interface • LIN-UART : 4 channels - Equipped with full-duplex double buffer - Clock-asynchronous or clock-synchronous serial transmission is available • I2C interface : 2 channels (only for devices with a C suffix in the part number) - Up to 400 kbps transfer rate • Interrupt controller • Powerful 8-level, 34-condition interrupt feature • Up to 16 external interrupts are supported • Automatic data transfer function independent of CPU - Expanded intelligent I/O service function (EI2OS) : up to 16 channels • I/O ports • General-purpose input/output port (CMOS output) - 80 ports (for devices without an S suffix in the part number - i.e. devices that support the sub clock) - 82 ports (for devices with an S suffix in the part number - i.e. devices that do not support the sub clock) • 8/10-bit A/D converter • 16 channels (only for devices without a C suffix in the part number) • 24 channels (only for devices with a C suffix in the part number) • Resolution is selectable between 8-bit and 10-bit. • Activation by external trigger input is allowed. • Conversion time : 3 μs (at 24 MHz machine clock, including sampling time) • Address match detection (program patch) function • Detects address matches against 6 address pointers • Timer • Time-base timer, watch timer, watchdog timer : 1 channel • 8/16-bit PPG timer : 8-bit × 16 channels, or 16-bit × 8 channels • 16-bit reload timer : 4 channels • 16-bit input/output timer - 16-bit free-run timer : 2 channels (FRT0 : ICU 0/1/2/3, OCU 0/1/2/3, FRT1 : ICU 4/5/6/7, OCU 4/5/6/7) - 16-bit input capture: (ICU): 8 channels - 16-bit output compare: (OCU): 8 channels (Continue ...)
