Product details
Overview
R5F1214CMSP#30 from Renesas Electronics is a 16-pin, 32 KB flash, 2 KB RAM RL78/G16 16-bit microcontroller designed for industrial applications up to +125°C. It integrates a capacitive touch sensing unit (15-channel), 8× 16-bit timers, 10-bit A/D converter (11-channel), real-time clock with calendar, and multiple serial interfaces including UART, simplified SPI (CSI), simplified I²C, and full I²C - enabling compact HMI and sensor control in thermally demanding environments.
For engineers reviewing the R5F1214CMSP#30 datasheet, R5F1214CMSP#30 pinout, R5F1214CMSP#30 application, or R5F1214CMSP#30 equivalent, this page delivers verified technical context, package-specific pin mapping, low-power operation details (HALT/STOP modes), industrial-grade temperature support (−40°C to +125°C), and validated alternative options for migration or second sourcing.
Technical Context
The R5F1214CMSP#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.0625 μs (@16 MHz high-speed on-chip oscillator) to 30.5 μs (@32.768 kHz subsystem clock). Its memory subsystem includes 32 KB code flash (1 KB block size), 1 KB data flash (512 B blocks, 1M rewrite cycles), and 2 KB on-chip RAM.
Peripheral integration centers on industrial interface robustness: 1–3 UART channels, 1–3 simplified SPI (CSI) channels, 1–3 simplified I²C channels, and 1 full I²C channel; plus analog resources including 10-bit A/D converter with internal reference (0.815 V), two comparators, and a dedicated capacitive touch sensing unit (CTSU) supporting self- and mutual-capacitance configurations across up to 16 keys.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F1214CGSP#30 | G-grade (−40°C to +105°C); identical pinout, memory, peripherals, and package - only temperature range differs. | Suitable for industrial applications not requiring +125°C operation, such as factory floor HMIs or non-enclosed control panels. | Select when full M-grade thermal margin is unnecessary and cost optimization is prioritized. |
| R5F1214AMSP#30 | 16 KB code flash (vs. 32 KB); otherwise identical M-grade spec, pinout, and peripherals - halved program memory capacity. | Applicable where firmware footprint is <16 KB and future feature expansion is not anticipated, e.g., fixed-function sensor nodes. | Choose for cost-sensitive, functionally locked applications where flash headroom is not required. |
Compared with R5F1214CGSP#30 and R5F1214AMSP#30, the R5F1214CMSP#30 uniquely combines extended +125°C operation with 32 KB flash - making it the only option among the three for thermally aggressive embedded control with room for firmware growth and safety-critical redundancy.

FAQ
What is the maximum operating temperature specification for the R5F1214CMSP#30?
The R5F1214CMSP#30 is qualified for industrial M-grade operation from −40°C to +125°C. This specification is confirmed in the datasheet's "Operating ambient temperature" section and applies across the full 2.4–5.5 V supply range. The device maintains full functionality-including ADC accuracy, CTSU sensitivity, and timer stability-at the upper limit, making it suitable for under-hood automotive and high-temperature industrial environments where the R5F1214CMSP#30 must operate continuously without derating.
Does the R5F1214CMSP#30 support in-system programming without external tools?
Yes, the R5F1214CMSP#30 supports on-chip debug and self-programming of its 32 KB code flash and 1 KB data flash using the integrated debug interface (via P40/TOOL0 and P00/P01 pins). No external programmer is required for firmware updates; the R5F1214CMSP#30 can execute flash writes autonomously during runtime, though background operation (BGO) is not supported for data flash - meaning code execution must pause during data flash rewrites.
How many capacitive touch channels does the R5F1214CMSP#30 support, and what configuration options exist?
The R5F1214CMSP#30 integrates a dedicated Capacitive Touch Sensing Unit (CTSU) supporting up to 15 self-capacitance channels or up to 16 mutual-capacitance keys via matrix configuration. All 15 CTSU channels are accessible on standard 16-pin SSOP package pins (e.g., P02/TSCAP, P03–P07, P137, P41, P40, P125, P122, P121, P20–P23), and the R5F1214CMSP#30's hardware accelerator handles scanning, noise cancellation, and baseline adjustment without CPU intervention.
What serial communication interfaces are available on the R5F1214CMSP#30, and how are they allocated on the 16-pin SSOP package?
The R5F1214CMSP#30 provides UART (up to 3 channels), simplified SPI (CSI, up to 3 channels), simplified I²C (up to 3 channels), and full I²C (1 channel). On the 16-pin SSOP package, UART0 uses P00 (TxD0) and P01 (RxD0); CSI0 uses P02 (SCK00), P03 (SO00), and P04 (SI00); simplified I²C0 uses P02 (SCL00) and P03 (SDA00); and full I²C0 uses P06 (SCLA0) and P07 (SDAA0) - all multiplexed and configurable via peripheral I/O redirection registers.
Is the R5F1214CMSP#30 pin-compatible with other RL78/G16 variants in the same package?
Yes, the R5F1214CMSP#30 is fully pin-compatible with all other RL78/G16 16-pin SSOP variants (e.g., R5F1214CGSP#30, R5F1214AMSP#30, R5F1214AASP#30) sharing the same SP package designation. Pin functions, electrical characteristics, and physical layout match exactly; only memory size (16 KB vs. 32 KB) and temperature grade (A/G/M) differ - enabling drop-in replacement during design iteration or qualification without PCB changes.
