1 Features
Ultra-low power consumption technology
• VDD = single power supply voltage of 1.
6 to 5.
5 V which can operate a 1.
8 V device 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.
03125 s: @ 32 MHz operation with high-speed on-chip oscillator) to ultra-low speed (30.
5 s: @ 32.
768 kHz operation with subsystem clock) • Multiply/divide/multiply & accumulate instructions are supported.
• Address space: 1 MB • General-purpose registers: (8-bit register 8) 4 banks • On-chip RAM: 5.
5 KB
Code flash memory
• Code flash memory: 32/64 KB • Block size: 1 KB • Prohibition of block erase and rewriting (security
function) • On-chip debug function • Self-programming (with boot swap function/flash shield
window function)
Data flash memory
• Data flash memory: 4 KB • Back ground operation (BGO): Instructions can be
executed from the program memory while rewriting the data flash memory.
• Number of rewrites: 1,000,000 times (TYP.
) • Voltage of rewrites: VDD = 1.
8 to 5.
5 V
High-speed on-chip oscillator
• Select from 64 MHz, 48 MHz, 32 MHz, 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) • TA = 40 to +105°C (G: Industrial applications)
Power management and reset function
• On-chip power-on-reset (POR) circuit • On-chip voltage detector (LVD) (Select interrupt and
reset from 14 levels)
Data transfer controller (DTC)
• Transfer modes: Normal transfer mode, repeat transfer mode, block transfer mode
• Activation sources: Activated by interrupt sources.
• Chain transfer function
