Product details
Overview
R5F104AGASP#V0 from Renesas Electronics 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 V to 5.5 V at up to 32 MHz (44 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes (0.60 μA RTC+LVD), integrated 10-bit ADC (20-channel), and real-time clock for battery-powered industrial sensor nodes.
For engineers reviewing the R5F104AGASP#V0 datasheet, R5F104AGASP#V0 pinout, R5F104AGASP#V0 application, or R5F104AGASP#V0 equivalent, key selection criteria include its 30-pin LSSOP-0.65mm package, -40°C to +85°C industrial temperature grade (A-field), 96 KB code flash with self-programming and security lock, and peripheral set including UART, I²C, CSI, and 16-bit TAU timers.
Technical Context
The R5F104AGASP#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 on-chip high-accuracy ±1.0% oscillator (1–64 MHz selectable). It integrates Data Transfer Controller (DTC) for autonomous memory transfers and Event Link Controller (ELC) for hardware-triggered peripheral chaining without CPU intervention.
Power management includes on-chip POR, 14-level LVD with interrupt/reset options, and multiple low-power modes-HALT (66 μA/MHz), STOP (0.60 μA with RTC+LVD active), and SNOOZE mode enabling background data flash rewriting during program execution via BGO.

The R5F104AGASP#V0 operates at up to 32 MHz with a peak performance of 44 DMIPS. Its RL78 CPU core achieves this with a 3-stage pipeline and supports variable instruction timing-from 0.03125 μs at full speed to 30.5 μs in ultra-low-speed RTC mode. This enables deterministic real-time control while maintaining sub-μA standby current in STOP mode.
Does the R5F104AGASP#V0 support in-system programming and secure firmware updates?
Yes, the R5F104AGASP#V0 supports full in-system programming via its on-chip debug interface and includes flash security features: block erase prohibition, flash shield window, and boot swap function. These mechanisms prevent unauthorized access or overwrite of critical firmware sections during field updates or debugging sessions.
What analog capabilities does the R5F104AGASP#V0 provide for sensor interfacing?
The R5F104AGASP#V0 integrates a 10-bit ADC with 20 input channels, internal 1.45 V reference voltage, and an on-chip temperature sensor. It supports single-ended and differential measurements, and its AVREFP/AVREFM pins allow precision ratiometric sensing-ideal for direct connection to resistive or capacitive sensors in industrial monitoring applications.
How does the R5F104AGASP#V0 manage power in battery-operated devices?
The R5F104AGASP#V0 delivers industry-leading low-power operation: 0.60 μA in STOP mode with RTC and LVD active, and 66 μA/MHz in HALT mode. Its multiple low-power states-including SNOOZE mode for background data flash writes-enable multi-year battery life in remote sensors without sacrificing responsiveness or data integrity.
Is the R5F104AGASP#V0 pin-compatible with other RL78/G14 variants in the same package?
Yes, all RL78/G14 devices in the 30-pin LSSOP package-including R5F104AGASP#V0, R5F104BGASP#V0, and R5F104CGASP#V0-share identical pinouts and electrical characteristics. Firmware and hardware designs are interchangeable across these variants, allowing scalable memory upgrades without PCB changes.
