Product details
Overview
R5F12008MNS#10 from Renesas Electronics is an 8 KB flash, 1 KB RAM RL78/G15 8-bit microcontroller in a 10-pin LSSOP package, operating from 2.4–5.5 V with −40°C to +125°C industrial temperature rating. It integrates an 8/10-bit ADC (4 channels), 8-channel 16-bit timer, UART, simplified I²C (2 channels), simplified SPI (2 channels), and on-chip debug - targeting compact embedded control in motor drives and sensor interfaces.
For engineers reviewing the R5F12008MNS#10 datasheet, R5F12008MNS#10 pinout, R5F12008MNS#10 application, or R5F12008MNS#10 equivalent, key selection criteria include its M-grade extended-temperature operation, 10-pin LSSOP footprint, 8 KB code flash with self-programming, integrated high-speed on-chip oscillator (±1.0% accuracy at −20°C to +85°C), and dual simplified I²C support for multi-sensor bus systems.
Technical Context
The R5F12008MNS#10 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling minimum instruction execution time of 0.0625 μs at 16 MHz. Its clock system combines selectable high-speed on-chip oscillator (1–16 MHz), low-speed on-chip oscillator (15 kHz), and external crystal input (X1/X2) for flexible timing control in power-sensitive applications.
Peripheral integration includes SAU0 serial array unit supporting UART, CSI (simplified SPI), and simplified I²C across two channels, plus TAU0 timer array unit delivering up to 8 independent 16-bit timer channels with PWM capability. The device supports background data flash rewriting only during code flash idle periods - no BGO - and uses a dedicated 12-bit interval timer for precise periodic wake-up from STOP mode.

FAQ
What is the maximum operating frequency of the R5F12008MNS#10 high-speed on-chip oscillator?
The R5F12008MNS#10 high-speed on-chip oscillator supports frequencies from 1 MHz to 16 MHz, selectable via option byte bits 0–2. At 16 MHz operation, the minimum instruction execution time is 0.0625 μs. Frequency accuracy is ±1.0% over −20°C to +85°C ambient, making it suitable for timing-critical but non-precision applications without external crystals.
Does the R5F12008MNS#10 support background data flash rewriting while executing code from flash?
No, the R5F12008MNS#10 does not support background operation (BGO) for data flash rewriting. Instructions cannot be executed from code flash memory while data flash is being rewritten. Code flash execution must be suspended during data flash write/erase cycles, requiring careful state management in firmware to avoid system lockup.
How many analog input channels does the R5F12008MNS#10 support, and what is their resolution?
The R5F12008MNS#10 supports 4 analog input channels (ANI0–ANI3) with configurable 8-bit or 10-bit resolution. It includes an internal 0.815 V reference voltage (TYP.) and supports external reference inputs (IVREF0), enabling accurate voltage measurement across its full −40°C to +125°C operating range without external precision references.
What debug interface does the R5F12008MNS#10 use, and how is it connected?
The R5F12008MNS#10 uses Renesas' on-chip debug support (OCDS) accessed via three dedicated pins: TOOL0 (P40), TOOLRxD (P01), and TOOLTxD (P00). This 3-wire interface enables full-speed debugging, flash programming, and real-time trace without external JTAG hardware - reducing BOM cost and board space in development and production test fixtures.
Is the R5F12008MNS#10 pin-compatible with other RL78/G15 variants in the same package?
Yes, the R5F12008MNS#10 is pin-compatible with R5F12018MSP#10 (16-pin SSOP) and R5F12007MNS#10 (10-pin LSSOP) within the same package family. Specifically, R5F12007MNS#10 shares identical pinout, electrical characteristics, and peripheral mapping - differing only in code flash size (4 KB vs. 8 KB) - enabling direct substitution in footprint-constrained designs.
