Product details
Overview
R5F1214AMNA#40 from Renesas Electronics is a 16-pin, 16 KB flash, 2 KB RAM RL78/G16 16-bit microcontroller in HWQFN-16 (3 × 3 mm, 0.5-mm pitch) package, operating from 2.4 to 5.5 V with −40°C to +125°C industrial temperature range. It integrates an 8/10-bit ADC (11-channel), capacitive touch sensing unit (15-channel), real-time clock with calendar, and multiple serial interfaces including UART, simplified SPI (CSI), and I²C.
For engineers reviewing the R5F1214AMNA#40 datasheet, R5F1214AMNA#40 pinout, R5F1214AMNA#40 application, or R5F1214AMNA#40 equivalent, this page delivers verified technical context, validated pin functions, confirmed low-power operation modes (HALT/STOP), and precise alternative selection guidance for industrial HMI, sensor node, and appliance control designs.
Technical Context
The R5F1214AMNA#40 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). It features on-chip debug, self-programming flash without boot swap, and background operation disabled during data flash rewrite.
Its peripheral set includes eight 16-bit timers, one 12-bit interval timer, watchdog timer with dedicated low-speed oscillator, and a 99-year real-time clock with alarm and correction. The capacitive touch sensing unit supports both self-capacitance (15 keys) and mutual capacitance (up to 16 keys) configurations using TSCAP and TSxx pins.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F1214CGNA#40 | Same package and pinout, but G-grade (−40°C to +105°C) and 32 KB flash | Suitable for industrial equipment with lower thermal margin; higher flash supports larger firmware or bootloader + app partitioning | Select when extended program storage or relaxed temperature requirement reduces cost vs. M-grade qualification |
| R5F1214AMSP#50 | Same M-grade temp and 16 KB flash, but SSOP-16 (4.4 × 5.0 mm, 0.65-mm pitch) package | Better manufacturability in wave-soldered legacy assemblies; larger footprint eases hand-soldering and probe access | Choose for through-hole compatible production lines or prototyping where QFN reflow is unavailable |
Compared with R5F1214AMNA#40, R5F1214CGNA#40 offers double flash capacity at lower temperature grade, while R5F1214AMSP#50 trades miniaturization for assembly flexibility - both retain identical peripheral sets and software compatibility.

FAQ
What is the maximum operating frequency of the R5F1214AMNA#40?
The R5F1214AMNA#40 supports a maximum CPU operating frequency of 16 MHz using its on-chip high-speed oscillator. Instruction execution time can be as fast as 0.0625 μs at this speed. External crystal oscillators up to several MHz may also be used via P121/P122 pins, but the core clock is internally divided and capped per RL78/G16 architecture limits. The R5F1214AMNA#40 does not support frequencies beyond 16 MHz in standard operation.
Does the R5F1214AMNA#40 support in-circuit debugging?
Yes, the R5F1214AMNA#40 supports full on-chip debugging via the TOOL0 (P40) and TOOLRxD/TOOLTxD (P01/P00) pins using Renesas E2 or E2 Lite debuggers. It includes hardware breakpoints, watchpoints, and real-time trace capabilities. Debug functionality remains active in HALT mode but is suspended in STOP mode - the R5F1214AMNA#40 must be woken via reset or selected interrupts to resume debugging.
How many capacitive touch channels does the R5F1214AMNA#40 support?
The R5F1214AMNA#40 integrates a dedicated Capacitive Touch Sensing Unit (CTSU) supporting up to 15 channels in self-capacitance mode (one pin per key) or up to 16 keys in mutual capacitance matrix configuration using any 15 available TSxx pins. All touch channels are hardware-accelerated and include built-in noise cancellation - no additional firmware overhead is required to run basic touch detection on the R5F1214AMNA#40.
What is the data flash endurance specification for the R5F1214AMNA#40?
The R5F1214AMNA#40 specifies 1,000,000 write/erase cycles (typical) for its 1 KB data flash memory, with each rewrite unit being 32 bits. Rewrites require full block erase (512 B) before programming, and background operation is not supported - code execution halts from flash during data flash programming. Voltage requirements for rewriting match the operating range: VDD = 2.4 V to 5.5 V.
Is the R5F1214AMNA#40 pin-compatible with other RL78/G16 variants in HWQFN-16?
Yes, all RL78/G16 devices in the HWQFN-16 package - including R5F1214Axxx and R5F1214Cxxx variants - share identical pinouts and mechanical dimensions. The R5F1214AMNA#40 is fully pin-compatible with R5F1214AGNA#40 and R5F1214ACNA#40, differing only in temperature grade (M vs. G vs. A) and flash size (16 KB vs. 32 KB). No PCB redesign is needed when migrating between these part numbers.
