Product details
Overview
R5F104AAASP#V0 from Renesas is a 30-pin LSSOP-packaged RL78/G14 16-bit microcontroller with 16 KB flash, 2.5 KB RAM, and 4 KB data flash, operating from 1.6–5.5 V at -40 to +85°C (A-grade), delivering 44 DMIPS at 32 MHz for ultra-low-power embedded control in battery-powered sensors and industrial HMI.
For engineers reviewing the R5F104AAASP#V0 datasheet, R5F104AAASP#V0 pinout, R5F104AAASP#V0 application, or R5F104AAASP#V0 equivalent, key selection criteria include its 66 μA/MHz active current, RTC+LVD-only 0.60 μA STOP mode, 30-pin LSSOP footprint, integrated 10-bit ADC (20-channel), and UART/SPI/I²C peripheral set optimized for cost-sensitive, low-power edge nodes.
Technical Context
The R5F104AAASP#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz), and includes multiply/divide/accumulate instructions within a 1 MB address space. It integrates a high-accuracy ±1.0% on-chip oscillator (1–64 MHz selectable) and dedicated low-speed oscillator for watchdog operation.
Peripheral subsystems include an Event Link Controller (ELC) enabling hardware-triggered peripheral chaining, Data Transfer Controller (DTC) supporting block/repeat transfers activated by interrupts, and background operation (BGO) for data flash rewriting while executing code from program memory - all coordinated under HALT/STOP/SNOOZE power modes.

The R5F104AAASP#V0 operates up to 32 MHz with a typical active current of 66 μA per MHz, resulting in ~2.1 mA total at full speed. Its ultra-low-power STOP mode draws only 0.60 μA when retaining RTC and LVD functionality - verified across the full -40 to +85°C temperature range per R01DS0053EJ0340 Rev. 3.40.
Does the R5F104AAASP#V0 support in-system programming and secure firmware updates?
Yes, the R5F104AAASP#V0 supports full in-system programming via on-chip debug interface and includes boot swap functionality plus flash shield window protection. These features enable field firmware updates while preventing unauthorized access to protected code sections - confirmed in Section 1.1 "Features" and Section 2.3 "Flash Memory" of the official datasheet.
How many analog input channels does the R5F104AAASP#V0 support, and what is the ADC resolution?
The R5F104AAASP#V0 integrates a 10-bit successive-approximation ADC with up to 20 analog input channels (ANI0–ANI19), including dedicated AVREFP/AVREFM reference pins and internal 1.45 V reference voltage. Channel count is fixed per device variant and fully supported in the 30-pin LSSOP package per Table 1-1 and Section 1.1 "A/D Converter".
What serial communication interfaces are available on the R5F104AAASP#V0?
The R5F104AAASP#V0 provides three UART/LIN channels, three CSI (SPI-compatible) channels, and four I²C/simplified I²C channels - all accessible through multiplexed pins on its 30-pin LSSOP package. Peripheral I/O redirection registers (PIOR0/1) allow dynamic assignment of these functions to designated pins as documented in Section 1.3.1 Pin Configuration.
Is the R5F104AAASP#V0 pin-compatible with other RL78/G14 variants in the same package?
Yes, all RL78/G14 devices in the 30-pin LSSOP package - including R5F104AAASP#V0, R5F104ADASP#V0, and R5F104AEASP#V0 - share identical pinouts, electrical characteristics, and peripheral mappings.
