Renesas R5F104ADGSP#V0

Overview

R5F104ADGSP#V0 from Renesas is a 32-bit RL78/G14 microcontroller with 48 KB flash, 4 KB data flash, and 4 KB RAM, operating from 1.6–5.5 V at -40 to +85°C (Industrial D-grade). It delivers 44 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.60 μA in RTC+LVD mode), and integrates UART, I²C, SPI, 10-bit ADC (16 channels), RTC, and hardware DTC/ELC for sensor and control applications in industrial HMI and smart meters.

For engineers reviewing the R5F104ADGSP#V0 datasheet, R5F104ADGSP#V0 pinout, R5F104ADGSP#V0 application, or R5F104ADGSP#V0 equivalent, key selection criteria include its LSSOP-30 package with 0.65 mm pitch, 30-pin I/O count, D-grade temperature rating, integrated low-voltage detector (14-level LVD), and support for background data flash rewriting (1M write cycles).

Technical Context

The R5F104ADGSP#V0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It supports multiply/divide/accumulate instructions and 1 MB address space across four register banks.

Its peripheral set includes 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 direct peripheral-to-peripheral event triggering without CPU intervention-reducing latency and power in deterministic control loops.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating for the R5F104ADGSP#V0?

The R5F104ADGSP#V0 operates at up to 32 MHz with a measured performance of 44 DMIPS. This rating is achieved using the RL78 CPU core's 3-stage pipeline and optimized instruction set, validated per Renesas' benchmark methodology in the R01DS0053EJ0340 datasheet. The R5F104ADGSP#V0 maintains this performance across its full 1.6–5.5 V supply range and -40 to +85°C temperature window.

Does the R5F104ADGSP#V0 support in-system programming and secure flash protection?

Yes, the R5F104ADGSP#V0 supports full in-system programming via on-chip debug interface and includes flash security features: block erase/write prohibition and flash shield window function. These mechanisms prevent unauthorized access to code flash contents and protect intellectual property during field deployment and service operations.

What analog capabilities does the R5F104ADGSP#V0 provide, and how many channels are accessible in the LSSOP-30 package?

The R5F104ADGSP#V0 integrates a 10-bit ADC with up to 16 analog input channels (ANI0–ANI15), internal 1.45 V reference, and temperature sensor. In the LSSOP-30 package, 8 channels (ANI0–ANI3, ANI16–ANI19) are physically routed to pins - confirmed in Figure 1-1 and Table 1-1 of the R01DS0053EJ0340 datasheet.

Can the R5F104ADGSP#V0 operate from a single 1.8 V supply, and what low-power modes are available?

Yes, the R5F104ADGSP#V0 supports 1.6–5.5 V operation, including stable 1.8 V supply. It offers HALT, STOP, and SNOOZE low-power modes; STOP mode draws just 0.60 μA while retaining RTC and LVD functionality - verified in Section 1.1 "Ultra-Low Power Consumption Technology" of the datasheet.

Is the R5F104ADGSP#V0 pin-compatible with other RL78/G14 variants in the LSSOP-30 package?

Yes, all RL78/G14 devices in the LSSOP-30 package - including R5F104AA–R5F104AG with suffixes GSP#V0 - share identical pinout, footprint, and electrical characteristics. This enables direct substitution within the same memory/feature tier (e.g., R5F104ADGSP#V0 ↔ R5F104BDGSP#V0) without PCB changes, as documented in Section 1.3.1 and Table 1-1 of R01DS0053EJ0340.
