16-bit Proprietary Microcontroller
CMOS
F2MC-16LX MB90895 Series
MB90F897/F897S/MB90V495G
■ 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.
*: “F2MC” is the abbreviation of Fujitsu Flexible Microcontroller.
■ FEATURES
Models that support +125°C
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
