MB90V495G
■ DESCRIPTION
MB90895 series devices are 16-bit general-purpose microcontrollers designed for applications which need high-
speed real-time processing. The devices of this series are high-performance 16-bit CPU microcontrollers em-
ploying of the dual operation flash memory and CAN controller on LQFP-48 small package.
The system, inheriting the architecture of F²MC*² 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.
*1 : These devices are under development. This datasheet provides preliminary information for the devices under
development.
*2 : “F²MC” is the abbreviation of FUJITSU Flexible Microcontroller.
■ FEATURES
• Models that support +125°C (MB90F897/S)
• Models that support +150°C (MB90F897Y/YS)
• 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/Y)
• 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
