Product details
Overview
R5F12007ANS#50 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 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 - all optimized for low-power industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F12007ANS#50 datasheet, R5F12007ANS#50 pinout, R5F12007ANS#50 application, or R5F12007ANS#50 equivalent, key selection considerations include its 8-pin LSSOP package, −40°C to +85°C operation (A-grade), 4 KB flash capacity, on-chip debug support, and integrated analog peripherals enabling compact, cost-sensitive embedded designs without external ADC or timing ICs.
Technical Context
The R5F12007ANS#50 implements the RL78-S2 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 (1–16 MHz, ±2.0% accuracy at −40°C to +85°C) and a 15 kHz low-speed oscillator for watchdog and STOP mode operation.
Power management includes HALT and STOP modes, selectable power-on-reset (SPOR) with four voltage thresholds, and true low-power design achieving 54 µA/MHz at 125°C. Peripheral integration centers on SAU0 (2-channel serial array unit), TAU0 (8-channel timer array unit), and a single comparator channel with internal/external reference selection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F12008ANS#50 | 8 KB code flash (vs. 4 KB), same 8-pin LSSOP package, identical peripherals and pinout. | Required when firmware exceeds 4 KB or future-proofing for feature expansion is needed. | Select R5F12008ANS#50 if bootloader, OTA update stack, or enhanced UI logic demands >4 KB flash. |
| R5F12017ASP#50 | 10-pin LSSOP package, adds one analog input (4-channel ADC), one additional I/O (P00), and second simplified SPI channel. | Suitable when extra GPIO or dual serial interfaces (e.g., I²C sensor + UART host) are required. | Choose R5F12017ASP#50 only if the design requires ≥9 GPIO or concurrent I²C + SPI communication paths. |
Compared with R5F12008ANS#50, the R5F12007ANS#50 saves cost and board space where 4 KB flash suffices; versus R5F12017ASP#50, it maintains minimal footprint and BOM count when 8-pin I/O and single serial interface meet requirements.

FAQ
What is the maximum operating frequency and instruction execution time of the R5F12007ANS#50?
The R5F12007ANS#50 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., at 1 MHz operation, minimum instruction time is 1.0 μs. This configurability allows precise trade-offs between performance and power consumption in the R5F12007ANS#50.
Does the R5F12007ANS#50 support in-system programming and field firmware updates?
Yes, the R5F12007ANS#50 supports self-programming of both code flash and data flash memory without requiring a boot swap function. It includes an on-chip debug interface (TOOL0/TOOLRxD/TOOLTxD) for programming and verification, and flash shield window functionality prevents unauthorized access. Firmware updates can be performed in-application using the provided flash control commands - a key capability for maintaining and upgrading deployed R5F12007ANS#50 units.
How many analog input channels does the R5F12007ANS#50 provide, and what is their resolution?
The R5F12007ANS#50 integrates an 8/10-bit successive approximation A/D converter with 3 analog input channels: ANI0, ANI2, and ANI3. Resolution is selectable per conversion, and the ADC operates across the full 2.4–5.5 V supply range. An internal reference voltage (0.815 V TYP.) is available for comparator use, but the ADC uses VDD as its reference unless externally configured - a design choice confirmed in the R5F12007ANS#50 datasheet section 1.1.
What package type and pin count does the R5F12007ANS#50 use?
The R5F12007ANS#50 is housed in an 8-pin plastic LSSOP package (4.4 × 3.6 mm, 0.65-mm pitch) with embossed tape packaging (#50 specification). This matches the "SP" package code in its part number and is distinct from WDFN, SOP, or SSOP variants. Pin functions are fully documented in Table 1-2 of the R5F12007ANS#50 datasheet, confirming compatibility with standard LSSOP footprints and reflow profiles.
Can the R5F12007ANS#50 operate reliably at elevated temperatures?
The R5F12007ANS#50 is rated for operation from −40°C to +85°C (A-grade), and its electrical specifications - including flash endurance, oscillator accuracy (±2.0%), and DC characteristics - are guaranteed across that full range. While the RL78/G15 family offers G-grade (−40°C to +105°C) and M-grade (−40°C to +125°C) variants, the R5F12007ANS#50 specifically conforms to the A-grade specification, making it suitable for consumer and commercial environments but not extended-temperature industrial deployments.
