Product details
Overview
R5F1214AMSP#70 from Renesas Electronics is a 16-pin, industrial-grade RL78/G16 16-bit microcontroller with 16 KB flash, 2 KB RAM, and integrated capacitive touch sensing (15-channel CTSU), operating from 2.4 V to 5.5 V across −40°C to +125°C. It features an RL78 CPU core (3-stage pipeline), 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), and I²C.
For engineers reviewing the R5F1214AMSP#70 datasheet, R5F1214AMSP#70 pinout, R5F1214AMSP#70 application, or R5F1214AMSP#70 equivalent, key selection criteria include its M-grade temperature rating (+125°C), LSSOP-16 package with 0.65-mm pitch, on-chip debug support, self-programmable flash without boot swap, and dedicated CTSU for robust human-machine interface implementation in space-constrained industrial controls.
Technical Context
The R5F1214AMSP#70 implements the RL78 CPU core with configurable instruction timing (0.0625 μs min @ 16 MHz high-speed oscillator or 30.5 μs @ 32.768 kHz subsystem clock) and 1 MB address space. Its low-power architecture supports HALT and STOP modes, with SPOR reset and voltage monitoring over 2.4–5.5 V.
It integrates a 10-bit A/D converter with internal reference (0.815 V), temperature sensor, and selectable analog inputs (ANI0–ANI6); two comparator channels with programmable speed and reference source; and a 15-channel capacitive touch sensing unit supporting both self- and mutual-capacitance configurations for up to 16 keys.

FAQ
What is the maximum operating temperature specification for the R5F1214AMSP#70?
The R5F1214AMSP#70 is rated for operation from −40°C to +125°C (M-grade industrial qualification). This specification is guaranteed across the full 2.4–5.5 V supply range and applies to all embedded peripherals including the 10-bit A/D converter, CTSU, and real-time clock. The device maintains timing accuracy and flash endurance within this range per Renesas datasheet R01DS0431EJ0130.
Does the R5F1214AMSP#70 support in-system programming via its TOOL interface?
Yes, the R5F1214AMSP#70 supports full in-system programming using the single-wire TOOL interface. It enables flash memory programming-including code and data flash-without removing the device from the target board. The R5F1214AMSP#70 implements self-programming functionality with flash shield window protection, though it does not support boot-swap functionality per the RL78/G16 datasheet.
How many capacitive touch channels does the R5F1214AMSP#70 provide, and what configuration modes are supported?
The R5F1214AMSP#70 integrates a 15-channel capacitive touch sensing unit (CTSU) supporting both self-capacitance (15 independent keys) and mutual-capacitance (matrix configuration up to 16 keys) modes. All 15 channels map directly to GPIO pins P00–P07, P125, P137, P40, P41, and P121–P122 as defined in the pin multiplexing table. No external components are required for basic operation.
What serial communication interfaces are available on the R5F1214AMSP#70, and how many instances of each?
The R5F1214AMSP#70 provides up to three UART channels, three simplified SPI (CSI) channels, three simplified I²C channels, and one full I²C interface. These are implemented via the Serial Array Unit (SAU) and Serial Interface IICA. Pin multiplexing allows flexible allocation-for example, P06/P07 support SCLA0/SDAA0 (full I²C), while P02/P03/P04 support CSI0 with SCK00/SI00/SO00 functions.
Is the R5F1214AMSP#70 pin-compatible with other RL78/G16 variants in the same package?
Yes, the R5F1214AMSP#70 is pin-compatible with all other RL78/G16 devices in the 16-pin SSOP (SP) package, including R5F1214AASP#70, R5F1214AGSP#70, R5F1214CASP#70, and R5F1214CGSP#70. Pin assignments, electrical characteristics, and peripheral mappings are identical; only flash size (16 KB vs. 32 KB) and temperature grade differ between A/G/M and A/C variants.
