Product details
Overview
R5F1211AGSP#70 from Renesas Electronics is a 10-pin, 16 KB flash, 2 KB RAM RL78/G16 16-bit microcontroller with integrated capacitive touch sensing (15-channel CTSU), 8/10-bit ADC (4-channel), dual comparators, real-time clock, and low-power STOP/HALT modes. It operates from 2.4–5.5 V and supports industrial temperature range (−40°C to +105°C), targeting compact HMI control in white goods and industrial sensors.
For engineers reviewing the R5F1211AGSP#70 datasheet, R5F1211AGSP#70 pinout, R5F1211AGSP#70 application, or R5F1211AGSP#70 equivalent, key selection criteria include its LSSOP-10 package, G-grade thermal rating, 16 KB code flash with self-programming, 4-channel analog input capability, and dedicated touch-sensing I/O mapping on P02–P04.
Technical Context
The R5F1211AGSP#70 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting instruction execution times from 0.0625 μs (16 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). Its memory subsystem includes 16 KB code flash (1 KB block erase), 1 KB data flash (512 B blocks, 1M rewrite cycles), and 2 KB SRAM.
Peripheral integration includes one 12-bit interval timer, eight 16-bit timer channels, watchdog timer with dedicated low-speed oscillator, RTC with 99-year calendar and alarm, simplified SPI/UART/I²C interfaces (up to 3 channels each), and a 15-channel capacitive touch sensing unit supporting both self- and mutual-capacitance configurations.

FAQ
What is the maximum operating frequency of the R5F1211AGSP#70?
The R5F1211AGSP#70 supports up to 16 MHz operation using its high-speed on-chip oscillator. At this frequency, the minimum instruction execution time is 0.0625 μs. The device also supports lower-frequency modes-including 32.768 kHz for RTC operation-with corresponding increases in instruction cycle time.
Does the R5F1211AGSP#70 support in-system programming of its flash memory?
Yes, the R5F1211AGSP#70 supports self-programming of its 16 KB code flash memory without requiring a boot swap function. This enables firmware updates directly in the target system using standard debug interfaces like TOOL0/TOOLRxD/TOOLTxD, provided appropriate flash write sequencing and erase-before-write protocols are followed.
How many capacitive touch channels does the R5F1211AGSP#70 support, and which pins are dedicated to touch sensing?
The R5F1211AGSP#70 integrates a 15-channel Capacitive Touch Sensing Unit (CTSU). On the 10-pin LSSOP package, dedicated touch pins include P02 (TSCAP), P01 (TS00), P03 (TS03), and P04 (TS04). Additional touch channels can be assigned via peripheral I/O redirection, but only these four pins are physically routed for CTSU use in this variant.
What is the data flash endurance specification for the R5F1211AGSP#70?
The R5F1211AGSP#70 features 1 KB of data flash memory rated for 1,000,000 write/erase cycles (typical). Each rewrite operates on 32-bit units, and the memory supports voltage-range operation from 2.4 V to 5.5 V. Background operation (BGO) is not supported-code execution halts during data flash writes.
Is an external crystal required for real-time clock operation in the R5F1211AGSP#70?
No, the R5F1211AGSP#70 includes RTC2, a fully integrated real-time clock with 99-year calendar and alarm functions that can operate using either an external 32.768 kHz crystal or the internal subsystem clock. When using the internal clock, RTC accuracy depends on the 32.768 kHz oscillator's ±1.5% tolerance over −40°C to +105°C.
