Product details
Overview
R5F1214AMSP#30 from Renesas Electronics is a 16-pin, industrial-grade RL78/G16 16-bit microcontroller with 16 KB code flash, 2 KB RAM, and integrated capacitive touch sensing (15-channel CTSU). It operates from 2.4–5.5 V, supports −40°C to +125°C ambient, and delivers ultra-low-power operation (61 µA/MHz at TA = 125°C) for battery-powered industrial HMI and sensor control applications.
For engineers reviewing the R5F1214AMSP#30 datasheet, R5F1214AMSP#30 pinout, R5F1214AMSP#30 application, or R5F1214AMSP#30 equivalent, key selection criteria include its 16-pin SSOP package, 16 KB flash/2 KB RAM memory configuration, M-grade temperature rating, integrated RTC and 10-bit A/D converter, and support for simplified SPI/I²C/UART interfaces in space-constrained embedded designs.
Technical Context
The R5F1214AMSP#30 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, enabling instruction execution times from 0.0625 µs (16 MHz high-speed on-chip oscillator) to 30.5 µs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, watchdog timer, and real-time clock with 99-year calendar and alarm functions.
Its peripheral set includes an 8/10-bit A/D converter with up to 11 analog inputs, two comparator channels with selectable reference sources, and a dedicated capacitive touch sensing unit supporting both self- and mutual-capacitance configurations across 15 pins - all operating within the same 2.4–5.5 V supply range as the core logic.

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 | Same 16-pin SSOP package and 16 KB/2 KB memory, but G-grade (−40°C to +105°C) and 16 MHz oscillator accuracy ±1.5% at TA = +85°C. | Targeted for industrial automation panels not requiring extended high-temp operation; lower cost where +105°C suffices. | Select when ambient temperature remains ≤+105°C and qualification to AEC-Q100 Grade 2 is not required. |
| R5F1214CMNA#20 | Same M-grade temperature rating but 16-pin HWQFN (3 × 3 mm, 0.5-mm pitch); identical flash/RAM and peripheral set. | Used where PCB space is constrained and thermal dissipation via exposed pad is preferred over SSOP leads. | Choose for high-density layouts needing 40% smaller footprint than SSOP; requires QFN reflow profile and thermal pad grounding. |
Compared with R5F1214CGSP#30 and R5F1214CMNA#20, the R5F1214AMSP#30 uniquely combines M-grade temperature resilience with the manufacturability and test accessibility of the SSOP package - ideal for through-hole prototyping, wave-soldered industrial assemblies, and legacy production lines not equipped for QFN handling.

FAQ
What is the maximum operating frequency and corresponding instruction execution time for the R5F1214AMSP#30?
The R5F1214AMSP#30 supports a high-speed on-chip oscillator up to 16 MHz, delivering a minimum instruction execution time of 0.0625 µs under those conditions. This timing is achievable with the high-speed on-chip oscillator enabled and no wait states inserted, making the R5F1214AMSP#30 suitable for deterministic real-time control loops in industrial motor and sensor applications.
Does the R5F1214AMSP#30 support in-system programming without external hardware?
Yes, the R5F1214AMSP#30 supports self-programming of its code flash memory via on-chip debug functionality using standard UART or simplified SPI interfaces - no external programmer is required. The R5F1214AMSP#30 does not implement boot swap, but its flash shield window function protects critical firmware sections during field updates.
How many analog input channels and what A/D resolution does the R5F1214AMSP#30 provide?
The R5F1214AMSP#30 integrates an 8/10-bit A/D converter with up to 11 analog input channels (ANI0–ANI10), configurable for single-ended or differential measurements. Its internal 0.815 V reference and temperature sensor allow for calibrated voltage, current, and thermal monitoring without external components - a key capability confirmed in the R5F1214AMSP#30 datasheet section 1.1.
What is the capacitive touch sensing capability of the R5F1214AMSP#30?
The R5F1214AMSP#30 includes a dedicated 15-channel capacitive touch sensing unit (CTSU) supporting both self-capacitance (up to 15 keys) and mutual-capacitance (up to 16 keys in matrix) configurations. It operates natively from the same 2.4–5.5 V supply as the core, eliminating external bias circuitry - a feature explicitly documented for the R5F1214AMSP#30 in the RL78/G16 datasheet Section 1.1.
Is an external crystal required for accurate UART communication on the R5F1214AMSP#30?
No, the R5F1214AMSP#30 features a high-accuracy on-chip oscillator with ±1.5% frequency stability over −40°C to +125°C, fully adequate for UART communication at standard baud rates (e.g., 9600–115200 bps) without external crystal. This capability is specified for M-grade devices like the R5F1214AMSP#30 in Table 1-1 of the datasheet and reduces BOM cost and layout complexity.
