Features

Ultra-low Power Consumption Technology

• VDD = single power supply voltage of 1.8 to 5.5 V which can operate at a low voltage
• HALT mode
• STOP mode
• SNOOZE mode

RL78 CPU core

• CISC architecture with 3-stage pipeline
• Minimum instruction execution time: Can be changed from high speed (0.04167 s: @ 24 MHz operation with high-speed on-chip oscillator) to ultra-low speed (1 s:@ 1 MHz operation)
• Address space: 1 MB
• General-purpose registers: (8-bit register x 8) x 4 banks
• On-chip RAM: 256 B to 2 KB

Code Flash Memory

• Code flash memory: 2 to 16 KB
• Block size: 1 KB
• Prohibition of block erase and rewriting (security function)
• On-chip debug function
• Self-programming (with flash shield window function)

High-speed on-chip oscillator

• Select from 24 MHz, 16 MHz, 12 MHz, 8 MHz, 6 MHz, 4 MHz, 3 MHz, 2 MHz, and 1 MHz
• High accuracy: +/- 1.0 % (VDD = 1.8 to 5.5 V, TA = -20 to +85 °C)

Operating ambient temperature

• TA = -40 to +85 °C (A: Consumer applications, D: Industrial applications)
• TA = -40 to +105 °C (G: Industrial applications) Note

Power management and reset function.

• On-chip power-on-reset (POR) circuit
• On-chip voltage detector (LVD) (Select interrupt and reset from 12 levels)
