1. OUTLINE
The MB90495-series with FULL-CAN interface and FLASH ROM is especially designed for automotive and industrial applications.
Its main feature is the on-chip CAN Interface, which conforms to V2.0 Part A and Part B, while supporting a very flexible message
buffer scheme, including 8 message buffers, and so offering more functions than a normal full CAN approach.
With the new 0.5 mm CMOS technology, Fujitsu now also offers on-chip FLASH-ROM program memory. An internal voltage
booster removes the necessity for a second programming voltage. An on-chip voltage regulator provides 3V to the internal MCU
core. This creates a major advantage in terms of EMI and power consumption.
The internal PLL clock frequency multiplier provides an internal 62.5 nsec instruction cycle time from an external 4 MHz clock. A
32kHz Subsystem clock has been included for power saving modes and real time measurement.
There are 2 on-chip UART's, which also provide synchronous communication modes. Furthermore the MCU features an 8 chan-
nel ADC, 8 channel External interrupt controller, two 16 bit PPG channels, 4 channel Input Capture Unit and a 16-bit free running
I/O-timer.
