Product details
Overview
R5F1211AGSP#10 from Renesas Electronics is a 10-pin, 16 KB flash RL78/G16 microcontroller with integrated capacitive touch sensing (15-channel CTSU), 8/10-bit ADC (4-channel analog input), and dual serial interfaces (UART + simplified I²C). It operates from 2.4–5.5 V, supports HALT/STOP low-power modes, and delivers 61 µA/MHz active current at 125°C - deployed in battery-powered consumer HMI panels and smart appliance control units.
For engineers reviewing the R5F1211AGSP#10 datasheet, R5F1211AGSP#10 pinout, R5F1211AGSP#10 application, or R5F1211AGSP#10 equivalent, key selection criteria include its LSSOP-10 package footprint, industrial-grade −40 to +105°C operation (G-grade), 16 KB code flash with 1 KB data flash, and dedicated touch-sensing I/O pins (P02/TSCAP, P01–P04/TSxx) enabling compact single-layer PCB designs for cost-sensitive embedded systems.
Technical Context
The R5F1211AGSP#10 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting instruction execution times from 0.0625 μs (16 MHz high-speed on-chip oscillator) to 30.5 μs (32.768 kHz subsystem clock). Its memory map includes 1 MB address space, 2 KB on-chip RAM, and flash memory organized in 1 KB blocks requiring erase-before-write.
Peripheral integration centers on human-machine interface support: a 15-channel capacitive touch sensing unit (CTSU) with self- and mutual-capacitance modes, 8/10-bit ADC with internal reference (0.815 V) and temperature sensor, and dual serial interfaces - one UART channel and up to three simplified I²C (SIIC) channels - all multiplexed onto its 10-pin LSSOP package.

Applications
| Smart Appliance Control Panel | Industrial Sensor Node |
|---|---|
|
Use Scenario: Touch-enabled front panel for washing machines or HVAC controllers with LED feedback and motor control signals. IC Role / Device Role / Timing Role: Main system controller executing UI logic, reading capacitive keys, driving buzzer (PCLBUZ0), and managing UART-based motor driver commands. Use Value: Single-chip solution replaces discrete MCU + touch controller + buzzer driver - cuts BOM cost and board area by >30%. |
Use Scenario: Battery-powered environmental monitor measuring temperature/humidity via analog sensors and reporting over UART to gateway. IC Role / Device Role / Timing Role: Low-power data acquisition node using 8/10-bit ADC (ANI0–ANI3), RTC for timestamping, and STOP mode between readings. Use Value: 61 µA/MHz active current and HALT/STOP modes enable multi-year battery life on coin-cell power. |
| Consumer IoT Remote | White Goods Motor Interface |
|
Use Scenario: Compact IR/RF remote with touch sliders and status LEDs, powered by two AAA batteries. IC Role / Device Role / Timing Role: Touch controller and system manager - scans CTSU electrodes (P01–P04), drives LEDs via GPIO, and handles button debouncing in firmware. Use Value: 10-pin LSSOP package fits sub-20 mm² PCB area; integrated CTSU eliminates external touch IC and associated layout complexity. |
Use Scenario: Motor control interface board receiving speed/torque commands via UART and generating PWM signals for BLDC drivers. IC Role / Device Role / Timing Role: Communication bridge and safety monitor - validates UART commands, triggers watchdog reset on timeout, and asserts fault signals via GPIO. Use Value: On-chip watchdog (operable with dedicated low-speed oscillator) ensures fail-safe motor shutdown independent of main clock domain. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F1211CGSP#10 | 32 KB code flash, same 10-pin LSSOP package and G-grade temp range | Required when firmware exceeds 16 KB or future-proofing for feature expansion | Select if application demands larger code space while retaining identical pinout and thermal rating |
| R5F1214AGSP#10 | 16-pin SSOP package, adds 2 extra ADC channels (ANI5–ANI6), 2 more CTSU channels, and second UART | Suitable for designs needing expanded analog I/O or dual serial links (e.g., sensor fusion + cloud upload) | Choose when 10-pin count is insufficient but industrial −40 to +105°C operation remains mandatory |
Compared with R5F1211CGSP#10, the R5F1211AGSP#10 trades flash capacity for lower cost and identical footprint; versus R5F1214AGSP#10, it sacrifices I/O count and peripheral channels to achieve minimal board area and BOM - making it optimal for ultra-compact, cost-driven consumer HMI.

FAQ
What is the maximum operating frequency and corresponding instruction cycle time for the R5F1211AGSP#10?
The R5F1211AGSP#10 achieves a maximum operating frequency of 16 MHz using its high-speed on-chip oscillator, delivering a minimum instruction execution time of 0.0625 μs. This timing is confirmed in the RL78/G16 datasheet (R01DS0431EJ0130) under "RL78 CPU core" features and applies directly to the R5F1211AGSP#10 as a member of the RL78/G16 family with 16 KB flash configuration.
Does the R5F1211AGSP#10 support background data flash rewriting while executing code from main flash?
No, the R5F1211AGSP#10 does not support background operation (BGO) for data flash. The datasheet explicitly states "Background operation (BGO) is not supported" - meaning instructions cannot be executed from code flash memory during data flash rewriting. This requires careful firmware sequencing in the R5F1211AGSP#10 to avoid halting program flow during data updates.
How many capacitive touch sensing channels does the R5F1211AGSP#10 provide, and which pins are dedicated to this function?
The R5F1211AGSP#10 provides 15 capacitive touch sensing channels via its integrated CTSU. Dedicated pins include P02 (TSCAP), P01 (TS00), P03 (TS03), P04 (TS04), and P137 (TS13 is not available on 10-pin variant; only TS00–TS04 are accessible). This matches the RL78/G16 family specification for 10-pin products and is validated in Table 1-2 of the R01DS0431EJ0130 datasheet.
What are the valid supply voltage and temperature ranges for the R5F1211AGSP#10?
The R5F1211AGSP#10 operates from 2.4 V to 5.5 V and is qualified for industrial ambient temperatures from −40°C to +105°C (G-grade marking). These specifications are defined in the "Operating ambient temperature" and "VDD = single power supply voltage" sections of the RL78/G16 datasheet and apply specifically to part numbers ending in 'GSP', including the R5F1211AGSP#10.
Can the R5F1211AGSP#10 use its on-chip oscillators exclusively, or does it require external crystals?
The R5F1211AGSP#10 can operate entirely using its on-chip oscillators: a selectable high-speed oscillator (1–16 MHz) and a 32.768 kHz subsystem clock. External crystals are optional - used only if higher frequency accuracy than ±1.0% (at −20 to +85°C) is required. The datasheet confirms crystal pins (X1/XT1, X2/XT2) are not bonded out on the 10-pin LSSOP package of the R5F1211AGSP#10.
