Overview
R5F1216CMSP#30 from Renesas Electronics is a 20-pin, 32 KB flash, 2 KB RAM RL78/G16 16-bit microcontroller with integrated capacitive touch sensing (15-channel CTSU), 10-bit A/D converter (11-channel), real-time clock with calendar, and industrial-grade operation up to +125°C. It features low-power HALT/STOP modes, high-speed on-chip oscillator (±1.5% accuracy at TA = −40 to +125°C), and dual serial interfaces including UART, simplified SPI (CSI), and I²C for embedded control in harsh environments.
For engineers reviewing the R5F1216CMSP#30 datasheet, R5F1216CMSP#30 pinout, R5F1216CMSP#30 application, or R5F1216CMSP#30 equivalent, key selection criteria include its LSSOP-20 package with 0.65-mm pitch, M-grade temperature rating (−40°C to +125°C), 32 KB code flash with 1 KB data flash, and dedicated CTSU support for robust human-machine interface implementation without external components.
Technical Context
The R5F1216CMSP#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling instruction execution times from 0.0625 μs (@16 MHz) to 30.5 μs (@32.768 kHz). Its memory subsystem includes 32 KB code flash (1 KB block size) and 1 KB data flash (512 B block size, 1M rewrite cycles), both operating across VDD = 2.4–5.5 V.
Peripheral integration includes an 11-channel 10-bit A/D converter with internal reference (0.815 V), two comparator channels supporting high/low-speed modes, eight 16-bit timer channels, one 12-bit interval timer, watchdog timer, and RTC2 with 99-year calendar and alarm function - all accessible via multiplexed I/O pins on the 20-pin LSSOP package.

FAQ
What is the maximum operating temperature specification for the R5F1216CMSP#30?
The R5F1216CMSP#30 is rated for industrial operation from −40°C to +125°C (M-grade qualification). This specification is guaranteed across the full VDD range of 2.4 V to 5.5 V and applies to all core functions, CTSU, A/D converter, timers, and serial interfaces as defined in the R01DS0431EJ0130 datasheet Rev. 1.30.
Does the R5F1216CMSP#30 support background data flash rewriting while executing code from flash memory?
No, the R5F1216CMSP#30 does not support background operation (BGO) for data flash rewriting. During data flash write/erase operations, instruction execution from code flash memory is halted. Firmware must schedule data flash updates during idle periods or STOP mode to maintain real-time responsiveness in the R5F1216CMSP#30 application.
How many capacitive touch sensing channels does the R5F1216CMSP#30 provide, and what configurations are supported?
The R5F1216CMSP#30 integrates a 15-channel Capacitive Touch Sensing Unit (CTSU) supporting both self-capacitance (up to 15 independent keys) and mutual-capacitance (matrix configuration with up to 16 keys) methods. All 15 channels map to dedicated pins (P02, P03, P04, P05, P06, P07, P20, P21, P22, P23, P40, P41, P121, P122, P125) as defined in the R5F1216CMSP#30 pinout documentation.
What oscillator options are available on the R5F1216CMSP#30, and what is the accuracy of the high-speed on-chip oscillator?
The R5F1216CMSP#30 supports a high-speed on-chip oscillator selectable from 16/8/4/2/1 MHz with ±1.5% frequency accuracy over −40°C to +125°C (M-grade), plus external crystal/resonator support via P121/P122. The subsystem clock uses a dedicated low-speed on-chip oscillator for watchdog and RTC operation independent of main clock domain.
Is the R5F1216CMSP#30 pin-compatible with other RL78/G16 variants in the same package type?
Yes, all RL78/G16 devices in the 20-pin LSSOP package (e.g., R5F1216AASP#30, R5F1216CGSP#30, R5F1216CMSP#30) share identical pinouts and electrical characteristics. Firmware and PCB designs are interchangeable across A/G/M grades and 16/32 KB flash variants, enabling seamless migration based on memory or temperature requirements without layout changes.
