■ F 2 MC-16L Family Features
• Faster version of the F 2 MC-16 (MB90700 series) with object code compatibility and also allows low
voltage operation.
• Easy programming with plenty of data types, including bit (1-bit), nibble (4-bit), byte (8-bit), word (16-bit), and
long word (32-bit), and 23 types of addressing.
• Bank and linear support of 16Mbytes memory space makes easy migration from external memory sizes to
singlechip systems.

16-bit per bank, 32 banks Max.
• Pipeline processing using 4 bytes cue (minimum instruction execution time: 62.5 ns/16 MHz)
• Powerful real time processing using 8-level hardware support priority interrupts and extended intelligent I/O ser-
vice functions.
• Extended C language and real time operating system instructions (SP indirect addressing, etc.)
• Can utilize external 4 MHz oscillator to run at 16 MHz internally by using a built-in clock multiplier circuitry.
• Number of basic instructions: 340 (fully compatible with the F 2 MC-16/16H)
