■ F 2 MC-16LX Family Features
• F 2 MC-16LX family is a high-performance 16-bit microcomputer having the upward compatibility with the
F 2 MC-16L family.
• Supporting 16-Mbyte memory space.
• Registers
Dedicated registers
General-purpose registers: 10
×
16-bit per bank, 32 banks Max.
• Clock multiplier circuit (

4) to protect your surrounding environment
Reducing the radiation interference
High-speed operation using the inexpensive low-speed oscillator (external 4 MHz; internal 16 MHz max.)
• Power management capabilities to contribute to the conservation of energy:
STOP, SLEEP, subclock, hardware standby
• AL 2 layers 0.5 µm (reducing the chip footprint)
• Low-voltage, low-power voltage dissipation
Supporting large memory (up to 256 Kbytes for ROM; up to 10 Kbytes for RAM)
• Power dissipation reduced by 60 % as compared to the earlier product (5 V compatible product)
