Overview
R5F1211CGSP#30 from Renesas Electronics is a 10-pin, industrial-grade RL78/G16 16-bit microcontroller with 32 KB code flash, 2 KB RAM, and integrated capacitive touch sensing (15-channel CTSU). It operates from 2.4–5.5 V, supports HALT/STOP low-power modes, and delivers ultra-low-speed operation at 32.768 kHz for battery-powered HMI applications.
For engineers reviewing the R5F1211CGSP#30 datasheet, R5F1211CGSP#30 pinout, R5F1211CGSP#30 application, or R5F1211CGSP#30 equivalent, key selection criteria include its 10-pin LSSOP package, −40°C to +105°C industrial temperature rating, 32 KB flash with self-programming capability, and dedicated CTSU for touch-button interfaces in space-constrained designs.
Technical Context
The R5F1211CGSP#30 implements the RL78 CPU core with a 3-stage pipeline, supporting instruction execution times from 0.0625 μs (16 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). Its memory architecture includes 32 KB on-chip code flash (1 KB block size), 1 KB data flash (512 B blocks), and 2 KB RAM.
It integrates a 10-bit A/D converter (4 analog inputs), 2-channel comparator, real-time clock with calendar function, 8× 16-bit timers, simplified SPI/I²C/UART interfaces (1 channel each), and a 15-channel capacitive touch sensing unit (CTSU) using self-capacitance configuration - all operating within a single 2.4–5.5 V supply rail.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F1211AGSP#30 | Same package and pinout; 16 KB code flash, consumer-grade (−40°C to +85°C) | Suitable for cost-sensitive, non-industrial applications with lower memory needs | Select when flash requirement ≤16 KB and ambient temperature stays below +85°C |
| R5F1214CGSP#30 | 16-pin SSOP package; adds 2 extra analog inputs (ANI5/ANI6), 1 extra UART/SPI channel | Required for designs needing >4 ADC channels or additional serial interfaces | Choose when expanding peripheral count beyond 10-pin constraints, accepting larger footprint |
Compared with R5F1211AGSP#30, the R5F1211CGSP#30 provides double flash capacity and extended temperature range critical for industrial deployment; versus R5F1214CGSP#30, it offers identical functionality in a smaller 10-pin LSSOP package but with fewer analog and serial resources - ideal for minimal-footprint touch interfaces.

FAQ
What is the maximum operating frequency and instruction timing of the R5F1211CGSP#30?
The R5F1211CGSP#30 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, where instruction timing extends to 30.5 μs - enabling precise real-time clock functions and ultra-low-power sleep modes. This dual-speed capability is managed entirely within the RL78 CPU core without external components.
Does the R5F1211CGSP#30 support in-system programming and debugging?
Yes, the R5F1211CGSP#30 supports full on-chip debug functionality via TOOL0 (P40), TOOLRxD (P01), and TOOLTxD (P00) pins. It enables non-intrusive debugging, breakpoint setting, and memory inspection. Self-programming of code flash is supported without boot swap functionality, allowing field firmware updates. However, background operation (BGO) is not available - code execution halts during data flash writes.
How many capacitive touch channels does the R5F1211CGSP#30 support, and what configuration options exist?
The R5F1211CGSP#30 integrates a 15-channel Capacitive Touch Sensing Unit (CTSU) supporting only the self-capacitance method in its 10-pin variant. Each channel maps directly to one GPIO pin (e.g., P02/TSCAP, P01/TS00, etc.), enabling up to 15 independent touch keys. Mutual capacitance matrix configuration is not available on this pin count due to insufficient dedicated transmit/receive pins - that capability requires ≥16-pin RL78/G16 variants like R5F1214CGSP#30.
What are the analog peripheral capabilities of the R5F1211CGSP#30?
The R5F1211CGSP#30 includes a 10-bit A/D converter with 4 analog input channels (ANI0–ANI3), an internal 0.815 V reference voltage, an on-die temperature sensor, and two comparator channels (IVCMP0/IVCMP1). It supports single-ended analog measurements referenced to VDD or internal references, and comparator outputs can be routed to interrupts (INTP4/INTP7) for threshold-triggered actions - all usable within the same 2.4–5.5 V supply domain without external support circuitry.
Is the R5F1211CGSP#30 pin-compatible with other RL78/G16 devices in the same package family?
Yes, the R5F1211CGSP#30 shares identical pinout, electrical characteristics, and mechanical dimensions with other 10-pin LSSOP RL78/G16 variants including R5F1211AGSP#30 and R5F1211AMSP#30. All share the same 10-pin mapping, power/ground locations, and peripheral multiplexing - enabling drop-in replacement across A/G/M grades when flash size and temperature requirements align. Pin compatibility does not extend to 16-pin or higher-count variants.
