Overview
R5F1214AASP#70 from Renesas Electronics is a 16-pin, consumer-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 HALT/STOP low-power modes, and delivers ultra-low-speed operation at 32.768 kHz for battery-powered HMI applications.
For engineers reviewing the R5F1214AASP#70 datasheet, R5F1214AASP#70 pinout, R5F1214AASP#70 application, or R5F1214AASP#70 equivalent, key selection criteria include its LSSOP-16 package, 16 KB flash/2 KB RAM memory configuration, A-grade temperature range (−40 to +85°C), and native support for simplified SPI, UART, I²C, and real-time clock with calendar function.
Technical Context
The R5F1214AASP#70 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, enabling instruction execution times adjustable from 0.0625 μs (16 MHz high-speed on-chip oscillator) to 30.5 μs (32.768 kHz subsystem clock). Its memory map spans 1 MB address space with banked 8-bit general-purpose registers.
It integrates a 12-bit interval timer, watchdog timer with dedicated low-speed oscillator, RTC2 with 99-year calendar and alarm, 8/10-bit ADC (up to 11 channels), two comparators, and a full-featured capacitive touch sensing unit supporting both self- and mutual-capacitance methods across 15 pins.

FAQ
What is the maximum operating frequency of the R5F1214AASP#70?
The R5F1214AASP#70 supports a maximum operating frequency of 32 MHz using the high-speed on-chip oscillator. Its minimum instruction execution time is 0.0625 μs at this speed, and it can scale down to 32.768 kHz for ultra-low-power RTC or standby operation. The oscillator accuracy is ±1.0% over −20°C to +85°C, making the R5F1214AASP#70 suitable for timing-critical yet cost-sensitive applications without external crystals.
Does the R5F1214AASP#70 support in-system programming?
Yes, the R5F1214AASP#70 supports in-system programming via its on-chip debug interface using P00 (TOOLTxD) and P01 (TOOLRxD) pins. It features self-programming capability for code flash and data flash without requiring a boot swap function. This allows firmware updates during normal operation or field service, and the R5F1214AASP#70 includes flash shield window protection to prevent unauthorized access.
How many capacitive touch channels does the R5F1214AASP#70 support?
The R5F1214AASP#70 integrates a 15-channel capacitive touch sensing unit (CTSU) supporting both self-capacitance (up to 15 keys) and mutual-capacitance (up to 16 keys in matrix configuration). All 15 channels are accessible via dedicated TSCAP and TSxx pins mapped across P02–P07, P137, P40, P41, and P20–P23 depending on package variant. This makes the R5F1214AASP#70 ideal for touch sliders, keypads, and proximity interfaces in consumer electronics.
What are the power supply requirements for the R5F1214AASP#70?
The R5F1214AASP#70 requires a single 2.4 V to 5.5 V supply on the VDD pin, with VSS as the corresponding ground reference. It operates across the full voltage range without level-shifting, supporting direct connection to 3.3 V or 5 V rails. The device includes an on-chip selectable power-on-reset (SPOR) circuit with three reset threshold levels, and its HALT/STOP modes reduce current consumption significantly - enabling battery operation in portable devices using the R5F1214AASP#70.
Is the R5F1214AASP#70 pin-compatible with other RL78/G16 variants?
The R5F1214AASP#70 is pin-compatible with other 16-pin RL78/G16 devices in the same package type (SSOP or LSSOP), including R5F1214CASP#70 and R5F1214AGSP#70. Pin assignments for power, reset, debug, analog, and peripheral functions are identical across these variants. Differences lie only in flash size (16 KB vs. 32 KB), temperature grade (A vs. G/M), and oscillator calibration - allowing drop-in replacement where voltage, timing, and qualification requirements align.
