Product details
Overview
R5F12007ANS#70 from Renesas Electronics is an 8-pin RL78/G15 16-bit microcontroller with 4 KB code flash, 1 KB RAM, and 1 KB data flash, operating from 2.4 V to 5.5 V. It integrates an 8/10-bit A/D converter (3 channels), 8-channel 16-bit timer array, UART, simplified I²C, and simplified SPI - deployed in low-power consumer and industrial sensor nodes, battery-powered controls, and smart peripherals.
For engineers reviewing the R5F12007ANS#70 datasheet, R5F12007ANS#70 pinout, R5F12007ANS#70 application, or R5F12007ANS#70 equivalent, key selection considerations include its LSSOP-8 package, −40°C to +85°C temperature grade (A), 4 KB flash capacity, on-chip debug support, and multiplexed analog/digital I/O with programmable clock/buzzer output.
Technical Context
The R5F12007ANS#70 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting minimum instruction execution times from 0.0625 μs (16 MHz) to 1.0 μs (1 MHz). Its clock system combines a high-speed on-chip oscillator (selectable 1–16 MHz, ±2.0% accuracy at TA = −40 to +85°C) and a 15 kHz low-speed on-chip oscillator for watchdog operation.
Power management includes HALT and STOP modes, selectable power-on-reset (SPOR) with four voltage thresholds, and true low-power design enabling operation up to +125°C in M-grade variants. The device supports background operation only for code flash erase/write; data flash rewrites require CPU halt and prohibit concurrent instruction fetch.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F12008ANS#70 | 8 KB code flash (vs. 4 KB), same pinout, identical peripherals and package. | Supports larger firmware images (e.g., OTA update stack + full BLE profile) without hardware change. | Select when future firmware growth or dual-bank update capability is required; otherwise R5F12007ANS#70 optimizes cost. |
| R5F12017ASP#70 | 10-pin LSSOP package; adds one analog input (ANI1), one I/O port (P00), and second simplified I²C channel. | Enables additional sensor inputs or I²C slave devices (e.g., EEPROM, temp sensor) without external logic. | Choose for designs needing >3 ADC channels or dual I²C buses; requires PCB redesign due to pin count increase. |
Compared with R5F12008ANS#70 and R5F12017ASP#70, the R5F12007ANS#70 delivers optimal cost-efficiency for fixed-function, space-constrained applications where 4 KB flash and 3-channel ADC meet requirements without over-provisioning.

FAQ
What is the maximum operating frequency and instruction execution time for the R5F12007ANS#70?
The R5F12007ANS#70 supports a maximum high-speed on-chip oscillator frequency of 16 MHz, yielding a minimum instruction execution time of 0.0625 μs under those conditions. The oscillator frequency is software-selectable (1/2/4/8/16 MHz), and execution time scales linearly - e.g., 1.0 μs at 1 MHz operation. This configurability allows precise trade-offs between performance and power consumption in battery-operated systems.
Does the R5F12007ANS#70 support in-system programming and debugging?
Yes, the R5F12007ANS#70 includes a full on-chip debug (OCD) function accessible via TOOL0, TOOLRxD, and TOOLTxD pins. It supports flash programming, breakpoint setting, and real-time variable inspection without external debug hardware. However, Renesas cautions against using OCD in mass-produced units due to potential flash endurance impact - the R5F12007ANS#70 is intended for development and evaluation, not production runtime debug access.
How many analog input channels does the R5F12007ANS#70 provide, and what reference options are available?
The R5F12007ANS#70 provides three analog input channels: ANI0, ANI2, and ANI3. It supports both internal and external reference voltages - the internal reference is fixed at 0.815 V (typical), while external references can be applied via IVREF0. This dual-reference capability enables accurate ratiometric measurements (e.g., resistive sensors) or absolute voltage readings independent of supply variation, directly within the R5F12007ANS#70's integrated A/D subsystem.
What serial communication interfaces are integrated into the R5F12007ANS#70?
The R5F12007ANS#70 integrates one UART channel (RxD0/TxD0), one simplified I²C interface (IIC00), and one simplified SPI interface (CSI00). All three share pins P01, P03, and P04 through configurable peripheral I/O redirection (PIOR), allowing flexible assignment without hardware changes. No dedicated I²C or SPI pins exist - routing is managed entirely in firmware, making the R5F12007ANS#70 highly adaptable to varying board layouts and protocol requirements.
What is the data flash endurance and rewrite voltage range for the R5F12007ANS#70?
The R5F12007ANS#70 features 1 KB of data flash memory rated for 1,000,000 rewrite cycles (typical) at VDD = 2.4 V to 5.5 V. Rewrites occur in 32-bit units and require full block erasure before writing. Background operation is not supported - the CPU must halt during data flash programming, and instruction fetch from code flash is disabled during the process. This architecture ensures data integrity but mandates careful scheduling of non-volatile parameter updates in real-time applications.
