Product details
Overview
R5F1211CGSP#10 from Renesas Electronics is a 10-pin, 32 KB flash RL78/G16 16-bit microcontroller designed for ultra-low-power industrial control applications. It features 2 KB RAM, 1 KB data flash, 10-bit A/D converter with up to 4 channels, capacitive touch sensing (15-channel CTSU), and operates from 2.4 V to 5.5 V across −40°C to +105°C.
For engineers reviewing the R5F1211CGSP#10 datasheet, R5F1211CGSP#10 pinout, R5F1211CGSP#10 application, or R5F1211CGSP#10 equivalent, key selection criteria include industrial-grade temperature support, integrated touch sensing for HMI, low-power HALT/STOP modes, and LSSOP-10 package compatibility with space-constrained embedded designs.
Technical Context
The R5F1211CGSP#10 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting instruction execution times from 0.0625 μs (@16 MHz) to 30.5 μs (@32.768 kHz). It integrates a high-speed on-chip oscillator (±1.0% accuracy at TA = −20 to +85°C) and a dedicated low-speed on-chip oscillator for watchdog and RTC operation.
Its peripheral set includes one 12-bit interval timer, eight 16-bit timers, one real-time clock with 99-year calendar and alarm, one 8/10-bit A/D converter (4-channel analog input), two comparator channels, and serial interfaces: up to three simplified SPI (CSI), three UART, three simplified I²C, and one full I²C channel - all configurable via multiplexed pins in the 10-pin LSSOP package.

FAQ
What is the maximum operating frequency and instruction timing of the R5F1211CGSP#10?
The R5F1211CGSP#10 supports a maximum operating frequency of 16 MHz using its high-speed on-chip oscillator. At this speed, the minimum instruction execution time is 0.0625 μs. The device also supports ultra-low-speed operation at 32.768 kHz (30.5 μs instruction time) using the subsystem clock - enabling flexible power/performance trade-offs in the R5F1211CGSP#10 design.
Does the R5F1211CGSP#10 support in-system programming and secure firmware updates?
Yes, the R5F1211CGSP#10 supports self-programming of its code flash memory without requiring a boot swap function.

Firmware updates can be performed in-application via UART or CSI interfaces - a key capability confirmed for the R5F1211CGSP#10 in industrial field-deployed devices.
How many analog input channels does the R5F1211CGSP#10 support, and what is the A/D resolution?
The R5F1211CGSP#10 integrates an 8/10-bit resolution A/D converter with up to 4 analog input channels (ANI0–ANI3), selectable via the P00–P04 pins. The internal reference voltage is 0.815 V (TYP.), and the A/D operates across the full 2.4–5.5 V VDD range - verified for the R5F1211CGSP#10 in the RL78/G16 datasheet Rev.1.30.
What touch sensing capabilities are built into the R5F1211CGSP#10?
The R5F1211CGSP#10 includes a 15-channel capacitive touch sensing unit (CTSU) supporting both self-capacitance (15 independent keys) and mutual-capacitance matrix configurations (up to 16 keys). This hardware-accelerated CTSU requires no external components and is fully integrated into the R5F1211CGSP#10 die - eliminating the need for companion touch controller ICs in HMI designs.
Is the R5F1211CGSP#10 pin-compatible with other RL78/G16 variants in the same package?
Yes, the R5F1211CGSP#10 shares identical pinout and electrical characteristics with other 10-pin LSSOP RL78/G16 devices including R5F1211AGSP#10 and R5F1211AMSP#10.
