Product details
Overview
R5F12008GNS#10 from Renesas Electronics is an 8 KB code flash, 1 KB RAM RL78/G15 10-pin LSSOP microcontroller operating at 2.4–5.5 V, featuring an 8-channel 16-bit timer, 4-channel 8/10-bit ADC, and UART + dual simplified I²C/CSI interfaces. It targets industrial sensor nodes and low-power control modules requiring −40°C to +105°C operation.
For engineers reviewing the R5F12008GNS#10 datasheet, R5F12008GNS#10 pinout, R5F12008GNS#10 application, or R5F12008GNS#10 equivalent, key selection criteria include its G-grade temperature rating, 10-pin LSSOP package with 8 I/Os, integrated high-speed on-chip oscillator (±1.0% accuracy at −20°C to +85°C), and support for background data flash writes only in non-execution mode.
Technical Context
The R5F12008GNS#10 implements the RL78 CPU core with a 3-stage CISC pipeline, enabling minimum instruction execution time of 0.0625 μs at 16 MHz using the high-speed on-chip oscillator. Its memory architecture separates 8 KB code flash (1 KB erase blocks) from 1 KB data flash (512 B blocks, 1M rewrite cycles), with no boot swap or background operation during data flash rewriting.
Peripherals include a single UART channel, two simplified I²C (IIC00/IICA0) channels, two simplified SPI (CSI00/CSI01) channels, one 12-bit interval timer, one watchdog timer, and a programmable clock/buzzer output (PCLBUZ0). Analog functions comprise four ADC inputs (ANI0–ANI3), one comparator (IVCMP0/IVREF0), and internal reference voltage (0.815 V).

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F12018GSP#10 | Same RL78/G15 core, identical 10-pin LSSOP package, but 4 KB code flash and 4-channel ADC (vs. 8 KB/4-channel) | Suitable for cost-sensitive designs where firmware size <32 KB and full 8 KB flash headroom is unnecessary | Select when firmware footprint is ≤3.5 KB and long-term code growth is unlikely |

FAQ
What is the maximum operating frequency of the R5F12008GNS#10 high-speed on-chip oscillator?
The R5F12008GNS#10 high-speed on-chip oscillator supports frequencies of 1 MHz, 2 MHz, 4 MHz, 8 MHz, or 16 MHz - selectable via option byte settings. At 16 MHz, the minimum instruction execution time is 0.0625 μs. Frequency accuracy is ±1.0% over −20°C to +85°C ambient, meeting industrial timing requirements without external crystals.
Does the R5F12008GNS#10 support background data flash rewriting while executing code from main flash?
No, the R5F12008GNS#10 does not support background operation (BGO) for data flash. During data flash rewriting, instruction execution from code flash memory is halted. This requires careful firmware design to pause application tasks, enter a safe state, and resume after the 512-byte block write completes - typically within milliseconds.
How many analog input channels are available on the R5F12008GNS#10, and what reference voltages can be used?
The R5F12008GNS#10 provides four analog input channels (ANI0–ANI3) with 8/10-bit resolution. Reference voltage options include the internal 0.815 V reference (IVREF0) or external voltage applied to the IVREF0 pin. The ADC operates across the full 2.4–5.5 V VDD range, enabling direct measurement of 0–VDD or scaled external signals.
What communication interfaces are integrated into the R5F12008GNS#10?
The R5F12008GNS#10 integrates one UART channel (RxD0/TxD0), two simplified I²C channels (IIC00 and IICA0), and two simplified SPI (CSI) channels (CSI00 and CSI01). All interfaces are software-configurable and share pins with GPIO functions via the Peripheral I/O Redirection Register (PIOR), allowing flexible peripheral mapping without hardware changes.
Is the R5F12008GNS#10 pin-compatible with other RL78/G15 10-pin variants like R5F12018GSP#10?
Yes, the R5F12008GNS#10 and R5F12018GSP#10 share identical 10-pin LSSOP packaging and pinout. Both support the same multiplexed functions on each pin (e.g., P01 = TOOLRxD/ANI0/SI00/RxD0). Firmware and PCB layouts are interchangeable - only flash size (8 KB vs. 4 KB) and data flash configuration differ, requiring no hardware revision.
