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 (0.04167 μs: @ 24 MHz operation with highspeed
on-chip oscillator) to ultra-low speed (30.5 μs: @ 32.768 kHz operation with subsystem clock)
• Address space: 1 MB
• General-purpose registers: (8-bit register × 8) × 4 banks
• On-chip RAM: 4 KB
Code flash memory
• Code flash memory: 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)
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
Power management and reset function
• On-chip power-on-reset (POR) circuit
• On-chip voltage detector (LVD) (Select interrupt and reset from 14 levels)
DMA (Direct Memory Access) controller
• 4 channels
• Number of clocks during transfer between 8/16-bit SFR and internal RAM: 2 clocks
Multiplier and divider/multiply-accumulator
• 16 bits × 16 bits = 32 bits (Unsigned or signed)
• 32 bits ÷ 32 bits = 32 bits (Unsigned)
• 16 bits × 16 bits + 32 bits = 32 bits (Unsigned or signed)
Serial interface
• CSI: 2 channels
• UART/UART (LIN-bus supported): 3, 4 channels/1 channel
• I2C/Simplified I2C communication: 1 channel/2 channels Timer
• 16-bit timer: 8 channels
• 12-bit interval timer: 1 channel
• Real-time clock 2 (with high accuracy 1 Hz output function): 1 channel (calendar for 99 years, alarm function, and
clock correction function)
• Watchdog timer: 1 channel (operable with the dedicated low-speed onchip
oscillator)
A/D converter
• 8/10-bit resolution A/D converter (VDD = 1.6 to 5.5 V)
• Analog input: 9 to 12 channels
• Internal reference voltage (1.45 V) and temperature sensorNote 1 Comparator
• 2 channels
• Operation mode: Comparator high-speed mode, comparator low-speed mode, or window mode
• External reference voltage and internal reference voltage are selectable
LCD controller/driver
• Segment signal output: 36 (32)Note 2
• Common signal output: 4 (8)Note 2
• Internal voltage boosting method and external resistance division method are switchableI/O port
• I/O port: 49 (N-ch open drain I/O [withstand voltage of 6 V]: 2, N-ch open drain I/O [VDD withstand voltage]: 12 to 18)
• Can be set to N-ch open drain, TTL input buffer, and on-chip pull-up resistor
• Different potential interface: Can connect to a 1.8/2.5/3 V device
• On-chip clock output/buzzer output controller Others
• On-chip BCD (binary-coded decimal) correction circuit
Notes 1. Can be selected only in HS (high-speed main) mode
2. The values in parentheses are the number of signal outputs when 8 com is used.
