RL78/G1M, G1N MCU

2020-08-21

Features:
Ultra-low power consumption technology

●V-DD = single power supply voltage of 2.0 to 5.5 V (Use this product within the voltage range from 2.25 to 5.5 V because the detection voltage (VSPOR) of the selectable power-on-reset (SPOR) circuit should also be considered.)

● HALT mode

● STOP mode RL78 CPU core

● CISC architecture with 3-stage pipeline

● Minimum instruction execution time: Can be changed from high speed (0.05 μs: @ 20 MHz operation with high-speed on-chip oscillator) to low speed (1.0 μs: @ 1 MHz operation)

●Address space: 1 MB

● General-purpose registers: 8-bit register × 8

● On-chip RAM: 512 B to 1 KB Code flash memory

● Code flash memory: 4 KB to 8 KB

● On-chip debug function High-speed on-chip oscillator

● Select from 20 MHz, 10 MHz, 5 MHz, 2.5 MHz, and

1.25 MHz

● High accuracy: ±2.0% (VDD = 2.0 to 5.5 V, TA = 20 to +85°C) Operating ambient temperature

● TA = 40 to +85°C Power management and reset function

● On-chip selectable power-on-reset (SPOR) circuit

Serial interface

● CSI: 1 channel

● UART: 1 channel Timer

● 8-/16-bit timer: 4 channels

● 12-bit interval timer: 1 channel

● Watchdog timer: 1 channel (operable with the dedicated low-speed on-chip oscillator)

● Real-time output function: 8 channels (RL78/G1M only) A/D converter

● 8/10-bit resolution A/D converter (VDD = 2.4 to 5.5 V)

● Analog input: 8 channels I/O port

● I/O port: 18 (N-ch open drain output [VDD withstand voltage]: 14) (P-ch open drain output [VDD withstand voltage]: 6)

● High current pin (RL78/G1N only)

● Can be set to N-ch open drain and on-chip pull-up resistor

● On-chip key interrupt function

● On-chip clock output/buzzer output controller Others

● On-chip BCD (binary-coded decimal) correction circui
