F2MC-16LX MB90895 Series
MB90F897/F897S/MB90V495G
s DESCRIPTION
MB90895 series devices are 16-bit micro general-purpose controllers designed for applications which need high-
speed real-time processing. The devices of this series are high-performance 16-bit CPU micro controllers em-
ploying of the dual operation flash memory and CAN controller on LQFP-48 small package.
The system, inheriting the architecture of F2MC* family, employs additional instruction ready for high-level lan-
guages, expanded addressing mode, enhanced multiply-divide instructions, and enriched bit-processing instruc-
tions. Furthermore, employment of 32-bit accumulator achieves processing of long-word data (32 bits).
The peripheral resources of MB90895 series include the following:
8/10-bit A/D converter, UART0/UART1 (SCI), 8/16-bit PPG timer, 16-bit input-output timer (16-bit free-run timer,
input capture 0, 1, 2, 3 (ICU)), and CAN controller.

s 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 4 times of oscillation clock (for 4-MHz oscillation clock, 4 MHz to 16 MHz).
• Operation by sub-clock (8.192 kHz) is allowed. (MB90F897)
• Minimum execution time of instruction: 62.5 ns (when operating with 4-MHz oscillation clock, and 4-time multi-
plied PLL clock).
• 16 Mbyte CPU memory space
• 24-bit internal addressing

• Sequence of Turning on Power of A/D Converter and Applying Analog Input
• Be sure to turn on digital power (Vcc) before applying signals to the A/D converter and applying analog input
signals (AN0 to AN7 pins).
• Be sure to turn off the power of A/D converter and analog input before turning off the digital power source.
• Be sure not to apply AVR exceeding AVcc when turning on and off. (No problems occur if analog and digital
power is turned on and off simultaneously.)
• Handling Pins When A/D Converter is Not Used
• If the A/D converter is not used, connect the pins under the following conditions: “AVcc=AVR=Vcc,” and
“AVss=Vss”
• Note on Turning on Power
• For preventing malfunctions on built-in step-down circuit, maintain a minimum of 50 µs of voltage rising time
(between 0.2 V and 2.7V) when turning on the power.
• Stabilization of supply voltage
• A sudden change in the supply voltage may cause the device to malfunction even within the specified VCC
supply voltage operating range. Therefore, the VCC supply voltage should be stabilized.
For reference, the supply voltage should be controlled so that VCC ripple variations (peak-to-peak values) at
commercial frequencies (50 Hz to 60 Hz) fall below 10% of the standard VCC supply voltage and the coefficient
of fluctuation does not exceed 0.1 V/ms at instantaneous power switching.
