Renesas R5F101AGASP#V0

Overview

R5F101AGASP#V0 from Renesas is a 30-pin, LSSOP-30 packaged RL78/G13 16-bit microcontroller with 96 KB flash, 8 KB data flash, and 8 KB RAM, operating from 1.6 V to 5.5 V. It delivers 41 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), and integrates 16-bit timers, 10-bit ADC (26 channels), UART, I²C, CSI, RTC, and DMA - deployed in battery-powered industrial sensors and smart metering endpoints.

For engineers reviewing the R5F101AGASP#V0 datasheet, R5F101AGASP#V0 pinout, R5F101AGASP#V0 application, or R5F101AGASP#V0 equivalent, key selection criteria include its data flash absence (vs. R5F100x variants), LSSOP-30 thermal profile, -40°C to +85°C A-grade temperature range, and support for self-programming with boot swap and flash shield window functions.

Technical Context

The R5F101AGASP#V0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling configurable instruction execution time from 0.03125 μs (32 MHz high-speed 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.

Power management includes HALT, STOP, and SNOOZE modes; on-chip POR and 14-level LVD support robust reset control. The peripheral set includes up to 16× 16-bit timers, 1× real-time clock with calendar/alarm/correction, and background operation-capable data flash rewriting (1M write cycles, 1.8–5.5 V).

FAQ

What is the maximum operating frequency and corresponding DMIPS rating for the R5F101AGASP#V0?

The R5F101AGASP#V0 operates at up to 32 MHz and delivers 41 DMIPS of processing performance. This benchmark reflects its RL78 CPU core's optimized 3-stage pipeline and instruction throughput under typical conditions. The R5F101AGASP#V0 achieves this performance while maintaining ultra-low power consumption - 66 μA per MHz in active mode - making it suitable for real-time control tasks in power-constrained environments.

Does the R5F101AGASP#V0 include data flash memory, and how does it differ from R5F100x variants?

No, the R5F101AGASP#V0 does not include data flash memory - a deliberate differentiation from the R5F100x series (e.g., R5F100AGASP#V0), which integrates 8 KB of data flash. The "101" prefix in the R5F101AGASP#V0 part number explicitly denotes no data flash. This omission reduces silicon cost and simplifies firmware design where persistent parameter storage is handled externally or unnecessary, while retaining identical code flash (96 KB), RAM (8 KB), peripherals, and package.

What package type and pin count does the R5F101AGASP#V0 use, and what are its thermal characteristics?

The R5F101AGASP#V0 uses a 30-pin plastic LSSOP package (7.62 mm × 9.9 mm, 0.65 mm pitch), designated by the "SP" suffix and "#V0" tray packaging code. Its thermal resistance (θ_JA) is 120°C/W per Renesas characterization, supporting operation up to +85°C ambient (A-grade). The LSSOP footprint provides robust solder joint reliability and moderate thermal dissipation - appropriate for sealed enclosures or convection-cooled industrial modules without forced airflow.

Which communication interfaces are integrated into the R5F101AGASP#V0, and how many instances does it support?

The R5F101AGASP#V0 integrates three serial interface types: CSI (Renesas' simplified SPI), UART (with LIN support), and I²C. Specifically, it supports up to 2 CSI channels, 2 UART channels (each capable of LIN bus framing), and 3 I²C/Simplified I²C channels. These interfaces share pins via multiplexing (e.g., P10/P11), allowing flexible peripheral assignment within the 30-pin constraint - enabling simultaneous connection to displays, sensors, and wireless transceivers in space-limited designs.

What low-power modes are available on the R5F101AGASP#V0, and what is the lowest achievable current draw?

The R5F101AGASP#V0 supports HALT, STOP, and SNOOZE low-power modes. In STOP mode with only RTC and LVD active, it achieves 0.57 μA typical current draw at VDD = 3.0 V and TA = 25°C. This ultra-low quiescent current enables decade-long operation on primary lithium batteries or energy-harvesting sources. Wake-up is supported via external interrupt, RTC alarm, or LVD threshold crossing - ensuring responsive yet frugal power management in always-on edge devices.
