Product details
Overview
R5F12008MNS#30 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 4-channel ADC, 8-channel 16-bit timer array, UART, two simplified I²C (IICA/IIC00), one simplified SPI (CSI00), watchdog timer, and on-chip high-speed oscillator (1–16 MHz ±1.0% at TA = −20 to +85°C). Used in motor control, sensor interface, and industrial power supply monitoring.
For engineers reviewing the R5F12008MNS#30 datasheet, R5F12008MNS#30 pinout, R5F12008MNS#30 application, or R5F12008MNS#30 equivalent, key selection criteria include its 10-pin LSSOP industrial-grade packaging, 8 KB code flash with self-programming, 4-channel analog input capability, and support for HALT/STOP low-power modes - all critical for compact embedded control designs requiring thermal robustness and mixed-signal integration.
Technical Context
The R5F12008MNS#30 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 memory subsystem includes 8 KB code flash (1 KB block size), 1 KB data flash (512 B block, 1M rewrite cycles), and 1 KB on-chip RAM.
Peripherals are managed via dedicated hardware units: TAU0 timer array supports 8 channels with PWM output capability; SAU0 serial array provides UART, CSI, and I²C functions; dual comparators (1 channel active) and 4-channel ADC operate with internal 0.815 V reference. Power management includes selectable SPOR reset levels and HALT/STOP modes for ultra-low-power operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F12018MSP#30 | Same RL78/G15 core, identical 8 KB flash/1 KB RAM, but in 16-pin SSOP package with 7-channel ADC and additional peripherals (X1/X2 crystal support, SAU0 channel 1) | Requires larger PCB footprint; supports crystal-based timing and expanded analog sensing | Select when crystal accuracy or >4 ADC channels are required; not drop-in compatible due to pin count and layout change |
| R5F12007MNS#30 | Pin-compatible 10-pin LSSOP variant with 4 KB code flash (vs. 8 KB), same RAM, ADC, and peripheral set | Lower memory capacity limits firmware complexity; suitable for simpler control tasks with smaller code size | Choose for cost-sensitive applications where 4 KB flash suffices; identical pinout and thermal rating enable direct substitution if code fits |
Compared with R5F12008MNS#30, R5F12018MSP#30 adds crystal oscillator support and analog channel count at the cost of board area, while R5F12007MNS#30 offers identical form factor and thermal performance with reduced flash - making it ideal for firmware-constrained cost targets without sacrificing industrial reliability.

FAQ
What is the maximum operating frequency and clock accuracy of the R5F12008MNS#30?
The R5F12008MNS#30 supports a maximum high-speed on-chip oscillator frequency of 16 MHz with ±1.0% accuracy over TA = −20°C to +85°C, and ±1.5% over TA = −40°C to −20°C or +85°C to +125°C. It does not support external crystal oscillation (X1/X2 pins are unassigned in the 10-pin LSSOP variant), so timing relies solely on the calibrated internal oscillator.
Does the R5F12008MNS#30 support crystal oscillator input?
No, the R5F12008MNS#30 in the 10-pin LSSOP package does not provide X1/X2 pins and therefore lacks crystal oscillator support. Its clock system relies exclusively on the high-speed on-chip oscillator (1–16 MHz selectable) and low-speed 15 kHz on-chip oscillator. Crystal-based timing is only available on 16-pin and 20-pin RL78/G15 variants.
How many analog input channels does the R5F12008MNS#30 support?
The R5F12008MNS#30 supports 4 analog input channels (ANI0 to ANI3), mapped to pins P01, P03, P04, and P02 respectively. All channels operate with 8/10-bit resolution and share the VDD supply as reference; internal 0.815 V reference is available for comparator use but not for ADC.
What debug interface does the R5F12008MNS#30 provide?
The R5F12008MNS#30 provides a 3-pin on-chip debug interface using TOOL0 (P40), TOOLRxD (P01), and TOOLTxD (P00). This enables full programming, breakpointing, and real-time variable inspection via Renesas E2 studio and CS+ IDE without external debug probes - though the on-chip debug function is intended for development only, not mass production use.
Is the R5F12008MNS#30 pin-compatible with other RL78/G15 10-pin variants?
Yes, the R5F12008MNS#30 shares identical pinout, package dimensions, and electrical characteristics with other 10-pin LSSOP RL78/G15 devices including R5F12017MSP#30 and R5F12018MSP#30. Differences are limited to flash size (4 KB vs. 8 KB) and minor peripheral enablement - all maintain full pin-to-pin compatibility for drop-in replacement within the same package family.
