产品详情

Ultra-low power consumption technology

o VDD = single power supply voltage of 1.6 to 5.5 V which can operate a 1.8 V device at a low voltage

o HALT mode

o STOP mode

o SNOOZE mode

RL78 CPU core

o CISC architecture with 3-stage pipeline

o 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)

o Address space: 1 MB

o General-purpose registers: (8-bit register × 8) × 4 banks

o On-chip RAM: 4 KB

Code flash memory

o Code flash memory: 64 KB

o Block size: 1 KB

o Prohibition of block erase and rewriting (security function)

o On-chip debug function

o Self-programming (with boot swap function/flash shield window function)

High-speed on-chip oscillator

o Select from 24 MHz, 16 MHz, 12 MHz, 8 MHz, 6 MHz, 4 MHz, 3 MHz, 2 MHz, and 1 MHz

o High accuracy: ±1.0 % (VDD = 1.8 to 5.5 V, TA = -20 to +85°C)

Operating ambient temperature

o TA = -40 to +85°C

Power management and reset function

o On-chip power-on-reset (POR) circuit

o On-chip voltage detector (LVD) (Select interrupt and reset from 14 levels)

DMA (Direct Memory Access) controller
o 4 channels
o Number of clocks during transfer between 8/16-bit SFR and internal RAM: 2 clocks
Multiplier and divider/multiply-accumulator
o 16 bits × 16 bits = 32 bits (Unsigned or signed)
o 32 bits ÷ 32 bits = 32 bits (Unsigned)
o 16 bits × 16 bits + 32 bits = 32 bits (Unsigned or signed)
Serial interface
o CSI: 2 channels
o UART/UART (LIN-bus supported): 3, 4 channels/1 channel
o I2C/Simplified I2C communication: 1 channel/2 channels Timer
o 16-bit timer: 8 channels
o 12-bit interval timer: 1 channel
o Real-time clock 2 (with high accuracy 1 Hz output function): 1 channel (calendar for 99 years, alarm function, and
clock correction function)
o Watchdog timer: 1 channel (operable with the dedicated low-speed onchip
oscillator)
A/D converter
o 8/10-bit resolution A/D converter (VDD = 1.6 to 5.5 V)
o Analog input: 9 to 12 channels
o Internal reference voltage (1.45 V) and temperature sensorNote 1 Comparator
o 2 channels
o Operation mode: Comparator high-speed mode, comparator low-speed mode, or window mode
o External reference voltage and internal reference voltage are selectable
LCD controller/driver
o Segment signal output: 36 (32)Note 2
o Common signal output: 4 (8)Note 2
o Internal voltage boosting method and external resistance division method are switchableI/O port
o 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)

o Can be set to N-ch open drain, TTL input buffer, and on-chip pull-up resistor
o Different potential interface: Can connect to a 1.8/2.5/3 V device
o On-chip clock output/buzzer output controller Others
o 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.
