Product details
Overview
R5F104AGASP#X0 from Renesas is a 30-pin LSSOP-packaged 16-bit RL78/G14 microcontroller with 96 KB flash, 12 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V at -40 to +85°C (A-grade). It delivers 44 DMIPS at 32 MHz, features ultra-low-power HALT/STOP/SNOOZE modes (66 μA/MHz active, 0.60 μA RTC+LVD), and integrates 10-bit ADC (20 channels), UART/SPI/I²C interfaces, RTC, and on-chip debug.
For engineers reviewing the R5F104AGASP#X0 datasheet, R5F104AGASP#X0 pinout, R5F104AGASP#X0 application, or R5F104AGASP#X0 equivalent, this device supports rapid prototyping of battery-powered industrial sensors, smart metering peripherals, and low-voltage HMI controllers where code density, power efficiency, and peripheral flexibility are critical selection criteria.
Technical Context
The RL78 CPU core uses a 3-stage CISC pipeline with configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz) and supports multiply/divide/accumulate operations. Its memory map spans 1 MB with four register banks (8×8-bit registers each).
Peripherals include Timer Array Unit (TAU) with up to 8 channels, 12-bit interval timer, real-time clock with calendar/alarm, watchdog timer, and Event Link Controller (ELC) enabling hardware-triggered peripheral chaining without CPU intervention.

Yes, the R5F104AGASP#X0 supports full in-system programming via its on-chip debug interface and includes boot swap functionality plus a flash shield window. These features allow authenticated firmware updates in the field without external programmers, while preventing unauthorized access to protected code sections during R5F104AGASP#X0 operation.
How many analog input channels does the R5F104AGASP#X0 ADC support, and what is its resolution?
The R5F104AGASP#X0 integrates a 10-bit successive-approximation ADC with up to 20 analog input channels (ANI0–ANI19), operating across the full 1.6–5.5 V supply range. It also includes an internal 1.45 V reference and on-die temperature sensor, enabling accurate analog measurements and thermal compensation without external components in the R5F104AGASP#X0 design.
What low-power modes are available on the R5F104AGASP#X0, and what are their typical current draws?
The R5F104AGASP#X0 offers HALT (66 μA/MHz), STOP (0.60 μA with RTC and LVD active), and SNOOZE modes. In STOP mode, the device maintains real-time clock operation and low-voltage detection while consuming less than 1 μA - ideal for battery-powered R5F104AGASP#X0 deployments requiring multi-year operation on primary cells.
Is the R5F104AGASP#X0 pin-compatible with other RL78/G14 variants in the same package?
Yes, all RL78/G14 devices in the 30-pin LSSOP package-including R5F104AGASP#X0, R5F104BGASP#X0, and R5F104EGASP#X0-share identical pinouts and electrical characteristics.
