OUTLINE

1.1

Features

Low power consumption technology

 VDD = single power supply voltage of 2.4 to 5.5 V

 HALT mode

 STOP mode

RL78 CPU core

 CISC architecture with 3-stage pipeline

 Minimum instruction execution time: Can be changed

from high speed (0.0625 μs: @ 16 MHz operation

with high-speed 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: 2 KB

Code flash memory

 Code flash memory: 16 to 32 KB

 Block size: 1 KB

 Only write after erase is possible

 On-chip debug function

 Self-programming (with no boot swap function/flash

shield window function)

Data flash memory

 Data flash memory: 1 KB

 Block size: 512 B

 Unit of rewrites: 32 bits

 Background operation (BGO) is not supported

(instructions cannot be executed from the code flash

memory while rewriting the data flash memory)

 Number of rewrites: 1,000,000 times (TYP.)

 Voltage of rewrites: VDD = 2.4 to 5.5 V

High-speed on-chip oscillator

 Select from 16 MHz, 8 MHz, 4 MHz, 2 MHz, and

1 MHz

 Frequency accuracy ±1.0%

(VDD = 2.4 to 5.5 V, TA = −20 to +85°C)

(G: Industrial applications, M: Industrial applications)

 Frequency accuracy ±1.5%

(VDD = 2.4 to 5.5 V, TA = −40 to −20°C)

(G: Industrial applications, M: Industrial applications)

 Frequency accuracy ±1.5%

(VDD = 2.4 to 5.5 V, TA = +85 to +105°C)

(G: Industrial applications)

 Frequency accuracy ±1.5%

(VDD = 2.4 to 5.5 V, TA = +85 to +125°C)

(M: Industrial applications)

 Frequency accuracy ±2.0%

(VDD = 2.4 to 5.5 V, TA = −40 to +85°C)

(A: Consumer applications)

Operating ambient temperature

 TA = −40 to +85°C (A: Consumer applications)

 TA = −40 to +105°C (G: Industrial applications)

 TA = −40 to +125°C (M: Industrial applications)

Power management and reset function

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

(Select reset from 3 levels, stop setting is available)

Serial interface

 Simplified SPI (CSINote 1): 1 to 3 channels

 UART:

1 to 3 channel

 Simplified I2C:

1 to 3 channels

 I2C:

1 channel

Note 1.

Although the CSI function is generally called

SPI, it is also called CSI in this product, so it

is referred to as such in this manual.

RL78/G16

RENESAS MCU

True low-power platform, 61-µA/MHz operating current, TA = 125°C operation, from 10 to 32 pins,
