Product details
Overview
R5F12007GNS#70 from Renesas Electronics is an RL78/G15 8-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 features an RL78 CPU core (3-stage pipeline), 8-channel 16-bit timer array, 3-channel 8/10-bit A/D converter, and integrated UART, simplified I²C, and simplified SPI interfaces. Designed for industrial temperature operation up to +105°C, it targets low-power sensor interface and control applications in HVAC, smart meters, and appliance subsystems.
For engineers reviewing the R5F12007GNS#70 datasheet, R5F12007GNS#70 pinout, R5F12007GNS#70 application, or R5F12007GNS#70 equivalent, key selection considerations include its 8-pin LSSOP package, G-grade industrial temperature rating (−40°C to +105°C), 4 KB flash capacity, on-chip high-speed oscillator (1–16 MHz selectable), and support for background-free data flash writes at full VDD range.
Technical Context
The R5F12007GNS#70 implements the RL78-S2 CPU core with CISC architecture, 1 MB address space, and configurable instruction execution time (0.0625 μs at 16 MHz to 1.0 μs at 1 MHz). Its clock system integrates a high-speed on-chip oscillator (±1.0% accuracy from −20°C to +85°C), low-speed 15 kHz oscillator, and optional external crystal (X1/X2) or EXCLK input up to 12 MHz.
Peripheral integration includes a single-channel comparator with internal/external reference selection, programmable clock/buzzer output (PCLBUZ0), selectable power-on-reset (SPOR) with four voltage thresholds, and on-chip BCD correction logic. Debug is supported via TOOL0/TOOLRxD/TOOLTxD pins using Renesas' on-chip debug function.

FAQ
What is the maximum operating temperature specification for the R5F12007GNS#70?
The R5F12007GNS#70 is rated for industrial operation from −40°C to +105°C (G-grade). This specification is guaranteed per Renesas' datasheet Rev.1.40 and applies to all electrical characteristics including flash programming, A/D conversion, and oscillator stability within that ambient range.
Does the R5F12007GNS#70 support crystal oscillator input?
Yes, the R5F12007GNS#70 supports external crystal oscillator input via X1/X2 pins-but only in 16-pin and 20-pin variants. The 8-pin R5F12007GNS#70 does not expose X1/X2 pins; it relies solely on its high-speed on-chip oscillator (1–16 MHz) and low-speed 15 kHz oscillator for clock generation.
How many analog input channels are available on the R5F12007GNS#70?
The R5F12007GNS#70 provides three analog input channels: ANI0 (on P01), ANI2 (on P03), and ANI3 (on P04). These are fully supported in the 8-pin LSSOP package and operate across the full 2.4–5.5 V VDD range with 8/10-bit resolution and internal 0.815 V reference.
Can the R5F12007GNS#70 perform data flash writes while executing code from main flash?
No. The R5F12007GNS#70 does not support background operation (BGO) for data flash. During data flash rewrite, instruction execution from code flash memory is halted-this is explicitly documented in the datasheet as "instructions cannot be executed from the code flash memory while rewriting the data flash memory."
What debug interface does the R5F12007GNS#70 use?
The R5F12007GNS#70 uses Renesas' on-chip debug interface accessed through three dedicated pins: TOOL0 (P40), TOOLRxD (P01), and TOOLTxD (P03). This interface enables full-featured debugging-including breakpoints, memory inspection, and flash programming-without requiring external JTAG hardware.
