Product details
Overview
R5F12008MNS#70 from Renesas Electronics is an 8-pin RL78/G15 16-bit microcontroller with 8 KB code flash, 1 KB RAM, and 1 KB data flash, operating from 2.4 V to 5.5 V across −40°C to +125°C industrial temperature range. It integrates a 16 MHz high-speed on-chip oscillator (±1.0% accuracy at −20°C to +85°C), 8-channel 16-bit timer, 3-channel 8/10-bit ADC, 1 comparator, UART, simplified SPI (CSI), and simplified I²C - deployed in smart sensors and industrial control nodes requiring low-power operation and extended thermal reliability.
For engineers reviewing the R5F12008MNS#70 datasheet, R5F12008MNS#70 pinout, R5F12008MNS#70 application, or R5F12008MNS#70 equivalent, key selection criteria include its M-grade 125°C rating, 8-pin LSSOP package, 8 KB flash capacity, integrated debug interface, and support for HALT/STOP low-power modes in resource-constrained embedded systems.
Technical Context
The R5F12008MNS#70 implements the RL78-S2 CPU core with CISC architecture and 3-stage pipeline, enabling minimum instruction execution time of 0.0625 μs at 16 MHz. Its memory subsystem includes 8 KB code flash (1 KB block size, erase-before-write), 1 KB data flash (512 B blocks, 1M rewrite cycles), and 1 KB SRAM - all accessible under single-supply operation.
Peripherals are tightly coupled to the TAU0 timer array (8 channels), SAU0 serial array (2 channels supporting CSI/UART/I²C), and analog subsystem comprising 3-channel ADC (8/10-bit, internal 0.815 V reference), single comparator (IVCMP0/IVREF0), and programmable clock/buzzer output (PCLBUZ0). Reset and power management include selectable SPOR with four voltage thresholds and dedicated low-speed 15 kHz watchdog oscillator.

FAQ
What is the maximum operating frequency and oscillator accuracy of the R5F12008MNS#70?
The R5F12008MNS#70 supports a maximum high-speed on-chip oscillator frequency of 16 MHz with ±1.0% accuracy over −20°C to +85°C, and ±1.5% over −40°C to −20°C or +85°C to +125°C. It does not require an external crystal for basic operation, though X1/X2 pins support 1–12 MHz crystal/ceramic resonators for higher precision timing.
Does the R5F12008MNS#70 support in-system programming and debug without external tools?
Yes, the R5F12008MNS#70 includes an on-chip debug function accessible via TOOL0, TOOLRxD, and TOOLTxD pins. It supports full in-circuit debugging and self-programming of code and data flash memory without requiring external debug probes - simplifying development and field firmware updates.
How many analog input channels and what ADC resolution does the R5F12008MNS#70 provide?
The R5F12008MNS#70 integrates an 8/10-bit successive approximation register (SAR) ADC with 3 analog input channels: ANI0, ANI2, and ANI3. It supports internal 0.815 V reference voltage (IVREF0) and operates across the full 2.4–5.5 V supply range, enabling direct sensor interfacing without external reference circuits.
What low-power modes are available on the R5F12008MNS#70 and how do they differ?
The R5F12008MNS#70 offers HALT mode (CPU halted, peripherals and interrupts active) and STOP mode (entire system halted except reset and selected wake-up sources like INTP0–INTP5). Both modes achieve sub-μA standby current, with STOP mode enabling wake-up in under 4 μs - ideal for battery-powered industrial sensors needing rapid response.
Is the R5F12008MNS#70 pin-compatible with other RL78/G15 variants in the same package?
Yes, the R5F12008MNS#70 is fully pin-compatible with R5F12007MNS#70 (4 KB flash) and shares identical 8-pin LSSOP pinout, electrical characteristics, and peripheral mapping - allowing seamless memory-scaling upgrades without PCB revision.
