Product details
Overview
R5F1216CGSP#30 from Renesas Electronics is a 20-pin, 32 KB flash RL78/G16 16-bit microcontroller with integrated capacitive touch sensing unit (15-channel CTSU), 10-bit A/D converter (11-channel), and real-time clock with calendar function. It operates from 2.4 V to 5.5 V, supports HALT/STOP low-power modes, and targets industrial HMI control in temperature ranges up to +105°C.
For engineers reviewing the R5F1216CGSP#30 datasheet, R5F1216CGSP#30 pinout, R5F1216CGSP#30 application, or R5F1216CGSP#30 equivalent, key selection criteria include its 20-pin LSSOP package, industrial-grade −40°C to +105°C operation, 32 KB code flash with 1 KB data flash, and hardware support for touch UI, serial interfaces (UART/SPI/I²C), and timer-based motor or buzzer control.
Technical Context
The R5F1216CGSP#30 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, enabling instruction execution times from 0.0625 μs (@16 MHz) to 30.5 μs (@32.768 kHz). Its memory subsystem includes 32 KB on-chip code flash (1 KB block size), 1 KB data flash (512 B block), and 2 KB RAM - all accessible without external bus interface.
Peripherals are tightly integrated: dual serial array units support up to three UART, SPI, or simplified I²C channels; the 16-bit timer array provides eight channels plus interval/RTC/watchdog timers; and the CTSU enables self- or mutual-capacitance touch detection across 15 pins without external components.

FAQ
What is the maximum operating frequency of the R5F1216CGSP#30?
The R5F1216CGSP#30 supports a maximum system clock frequency of 16 MHz using the high-speed on-chip oscillator. This yields a minimum instruction execution time of 0.0625 μs. The device also supports lower-frequency clock sources including a 32.768 kHz subsystem clock for ultra-low-power RTC operation. Frequency selection is software-configurable via system control registers.
Does the R5F1216CGSP#30 support in-system programming (ISP)?
Yes, the R5F1216CGSP#30 supports self-programming of its on-chip flash memory without requiring a boot swap function. Code flash and data flash can be rewritten in-system using the on-chip debug interface and dedicated flash control registers. Voltage requirements for rewriting are met within the normal VDD range of 2.4 V to 5.5 V.
How many capacitive touch channels does the R5F1216CGSP#30 support?
The R5F1216CGSP#30 integrates a Capacitive Touch Sensing Unit (CTSU) supporting up to 15 channels. It operates in self-capacitance mode (one key per pin) or mutual-capacitance matrix mode (up to 16 keys using transmit/receive pin combinations), all implemented in hardware without consuming CPU cycles during scanning.
What serial communication interfaces are available on the R5F1216CGSP#30?
The R5F1216CGSP#30 provides two serial array units supporting up to three channels total of UART, simplified SPI (CSI), or simplified I²C (SI²C). It also includes one dedicated I²C interface (IICA) and supports peripheral I/O redirection to assign functions like TxD/RxD/SCK/SDA to multiple pins - enabling flexible board layout and interface routing.
Is an external crystal required for RTC operation on the R5F1216CGSP#30?
No, the R5F1216CGSP#30 includes a dedicated low-speed on-chip oscillator for RTC2 operation, eliminating the need for an external 32.768 kHz crystal. The RTC2 module provides a full 99-year calendar, alarm function, and clock correction capability - all functional with only the internal oscillator and VDD supply.
