Product details
Overview
R5F1216AMSP#30 from Renesas Electronics is a 20-pin, industrial-grade RL78/G16 16-bit microcontroller with 32 KB flash, 2 KB RAM, and integrated capacitive touch sensing (15-channel CTSU), operating 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 low-power STOP/HALT modes - deployed in smart appliance control panels requiring robust HMI and thermal resilience.
For engineers reviewing the R5F1216AMSP#30 datasheet, R5F1216AMSP#30 pinout, R5F1216AMSP#30 application, or R5F1216AMSP#30 equivalent, key selection criteria include its 20-pin LSSOP package, M-grade temperature rating, on-chip CTSU for button-free interfaces, and dual serial interface support (UART + simplified I²C) without external timing components.
Technical Context
The R5F1216AMSP#30 implements the RL78 CPU core with CISC architecture and configurable instruction timing (0.0625 μs min @ 16 MHz to 30.5 μs @ 32.768 kHz), enabling dynamic power/performance scaling. Its memory subsystem includes 32 KB code flash (1 KB blocks), 1 KB data flash (512 B blocks, 1M rewrite cycles), and 2 KB SRAM - all accessible under single 2.4–5.5 V supply.
Peripheral integration centers on human-machine interaction: 15-channel capacitive touch sensing unit (CTSU) supporting self- and mutual-capacitance configurations, 10-bit A/D converter with internal reference (0.815 V) and temperature sensor, and dual serial interfaces - one full I²C channel plus up to three simplified I²C/SPI/UART channels via shared serial array units.

FAQ
What is the maximum operating temperature of the R5F1216AMSP#30?
The R5F1216AMSP#30 is rated for continuous operation from −40°C to +125°C (M-grade), validated per JEDEC JESD22-A108. This makes it suitable for deployment in high-temperature environments such as motor drive housings, sealed industrial enclosures, and automotive under-hood modules where ambient heat exceeds +105°C.
Does the R5F1216AMSP#30 support in-system programming via its debug interface?
Yes, the R5F1216AMSP#30 supports full in-system programming using the on-chip debug function via the TOOLRxD/TOOLTxD pins. Firmware updates can be performed without removing the device from the PCB, and the 32 KB code flash supports erase/write operations in-application without boot swap functionality.
How many capacitive touch channels does the R5F1216AMSP#30 support, and what configurations are available?
The R5F1216AMSP#30 integrates a 15-channel capacitive touch sensing unit (CTSU). It supports self-capacitance mode (15 independent keys, one per pin) and mutual-capacitance matrix mode (up to 16 keys using transmit/receive pin combinations from the same 15-pin pool), all implemented in hardware without CPU overhead.
Can the R5F1216AMSP#30 operate from a single-cell Li-ion battery without external regulation?
Yes, the R5F1216AMSP#30 operates across 2.4 V to 5.5 V, covering the full discharge curve of a single-cell Li-ion (2.7–4.2 V nominal) or LiFePO₄ (2.0–3.6 V) battery. Its HALT and STOP low-power modes reduce current draw to sub-μA levels, enabling multi-year battery life in always-on sensor nodes.
Is the R5F1216AMSP#30 pin-compatible with other RL78/G16 variants in the 20-pin LSSOP package?
Yes, all RL78/G16 20-pin LSSOP variants - including R5F1216AASP#30 (A-grade), R5F1216CGSP#30 (G-grade), and R5F1216CMSP#30 - share identical pinout, electrical characteristics, and peripheral mapping. Only the temperature grade and flash size (16 KB vs. 32 KB) differ between A/C suffixes; the R5F1216AMSP#30 uses the C-flash variant.
