Renesas R5F100AFDSP#V0

Overview

R5F100AFDSP#V0 from Renesas is a 30-pin LSSOP-packaged 16-bit RL78/G13 microcontroller with 96 KB flash, 4 KB data flash, and 4 KB RAM, operating from 1.6–5.5 V at up to 32 MHz (41 DMIPS), optimized for ultra-low-power consumer applications (−40°C to +85°C) such as smart home sensors and battery-powered industrial controls.

For engineers reviewing the R5F100AFDSP#V0 datasheet, R5F100AFDSP#V0 pinout, R5F100AFDSP#V0 application, or R5F100AFDSP#V0 equivalent, key selection criteria include its 30-pin LSSOP-30 package, integrated RTC + LVD, 10-bit 26-channel ADC, and support for SNOOZE mode (66 μA/MHz active, 0.57 μA in RTC+LVD-only operation).

Technical Context

The R5F100AFDSP#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). It integrates a 12-bit interval timer, real-time clock with calendar/alarm, and watchdog timer with dedicated low-speed on-chip oscillator.

Its peripheral set includes up to 26 analog inputs for the 10-bit ADC, 3–10 I²C channels, 2–4 UART/LIN interfaces, and 2–8 CSI (SPI-compatible) channels - all accessible within its 30-pin LSSOP footprint while maintaining HALT/STOP/SNOOZE power modes and on-chip debug functionality.

FAQ

What is the maximum operating frequency and performance of the R5F100AFDSP#V0?

The R5F100AFDSP#V0 operates at up to 32 MHz with a peak performance of 41 DMIPS. Its RL78 CPU core achieves this using a 3-stage pipeline and high-accuracy on-chip oscillator (±1.0% over −20°C to +85°C). The R5F100AFDSP#V0 maintains consistent timing across voltage (1.6–5.5 V) and temperature (−40°C to +85°C) ranges, making it suitable for deterministic real-time control tasks in the R5F100AFDSP#V0 design.

Does the R5F100AFDSP#V0 include an integrated analog-to-digital converter, and what are its key specs?

Yes, the R5F100AFDSP#V0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It supports internal 1.45 V reference voltage and on-chip temperature sensing (enabled only in HS mode). The ADC operates across the full supply range (1.6–5.5 V) and delivers typical INL of ±1 LSB. This capability is fully implemented in the R5F100AFDSP#V0 silicon and documented in the RL78/G13 datasheet Rev. 3.80.

What power-saving modes does the R5F100AFDSP#V0 support, and what are their typical current draws?

The R5F100AFDSP#V0 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws 0.57 μA typical. Active-mode current is 66 μA/MHz at 32 MHz. SNOOZE mode enables peripheral operation (e.g., ADC conversion, UART receive) while CPU remains halted, reducing average power in duty-cycled applications. These values are measured and specified for the R5F100AFDSP#V0 under standard test conditions in the official datasheet.

Is the R5F100AFDSP#V0 pin-compatible with other RL78/G13 variants in the same package?

Yes, all RL78/G13 devices in the 30-pin LSSOP package-including R5F100AFDSP#V0, R5F100BF DSP#V0, and R5F101AF DSP#V0-share identical pinouts and electrical characteristics. This allows hardware reuse across memory variants and simplifies migration paths. Pin compatibility is guaranteed by Renesas' package-level design consistency and verified in the RL78/G13 pin configuration diagrams (Page 13, Rev. 3.80).

What debug and programming interfaces are supported by the R5F100AFDSP#V0?

The R5F100AFDSP#V0 supports on-chip debugging via the single-wire debug interface (SWD) using the TOOLRxD/TOOLTxD pins (P11/P12), compatible with Renesas E2 emulator and CS+ IDE. It also supports self-programming via on-chip boot ROM, enabling firmware updates through UART or other serial interfaces without external programmers. This debug architecture is integral to the R5F100AFDSP#V0 and confirmed in Section 1.1 and Section 22 of the RL78/G13 datasheet.
