Renesas R5F100AEASP#V0

Overview

R5F100AEASP#V0 from Renesas is a 32-bit RL78/G13 microcontroller with 64 KB flash, 4 KB data flash, and 4 KB RAM, operating at up to 32 MHz (41 DMIPS), supporting ultra-low-power modes (0.57 μA RTC+LVD), 10-bit ADC (26 channels), and multiple serial interfaces (UART, I²C, CSI) in a 30-pin LSSOP package for industrial control and sensor node applications.

For engineers reviewing the R5F100AEASP#V0 datasheet, R5F100AEASP#V0 pinout, R5F100AEASP#V0 application, or R5F100AEASP#V0 equivalent, key selection criteria include its 64 KB code flash with self-programming, 10-bit ADC resolution across 26 analog inputs, real-time clock with calendar function, low-voltage detection at 14 selectable levels, and support for LIN-bus communication via UART.

Technical Context

The R5F100AEASP#V0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, real-time clock with alarm and correction functions, and watchdog timer powered by a dedicated low-speed on-chip oscillator.

Power management includes HALT, STOP, and SNOOZE modes, with on-chip POR and LVD (14-level voltage detection). The device supports background operation of data flash rewriting while executing program code, and features DMA with 2/4 channels transferring between SFR and internal RAM in just 2 clocks per 8/16-bit transfer.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating for the R5F100AEASP#V0?

The R5F100AEASP#V0 operates at a maximum frequency of 32 MHz, delivering 41 DMIPS (Dhrystone MIPS) performance. This is achieved using the high-speed on-chip oscillator, which maintains ±1.0% accuracy across the full supply (1.8–5.5 V) and temperature (–40°C to +85°C) range. The RL78 CPU core's 3-stage pipeline and efficient CISC instruction set enable this performance at ultra-low power.

Does the R5F100AEASP#V0 include an integrated temperature sensor and internal voltage reference for the ADC?

Yes, the R5F100AEASP#V0 includes both an integrated temperature sensor and an internal 1.45 V reference voltage (AVREFP/AVREFM) usable with its 10-bit ADC. The temperature sensor is accessible only in HS (high-speed main) mode and provides factory-calibrated output for ambient temperature measurement. The internal reference eliminates the need for external precision references in many sensor interface designs.

How many analog input channels does the R5F100AEASP#V0 support, and what is the ADC resolution?

The R5F100AEASP#V0 supports up to 26 analog input channels with a 10-bit successive-approximation ADC. Channel mapping depends on pin configuration and package - the 30-pin LSSOP variant (R5F100AEASP#V0) provides 26 usable ANI pins, including dedicated AVREFP/AVREFM terminals. Resolution is fixed at 10 bits; no hardware-configurable 8-bit mode is present.

What low-power modes are supported by the R5F100AEASP#V0, and what is the lowest achievable current draw?

The R5F100AEASP#V0 supports HALT, STOP, and SNOOZE low-power modes. In STOP mode with only the real-time clock (RTC) and low-voltage detector (LVD) active, it achieves 0.57 μA typical current draw at VDD = 3.0 V and TA = 25°C. This enables multi-year battery life in always-on sensor applications while retaining timekeeping and brown-out monitoring capability.

Is the R5F100AEASP#V0 pin-compatible with other RL78/G13 variants in the same 30-pin LSSOP package?

Yes, all RL78/G13 devices in the 30-pin LSSOP package (e.g., R5F100AAASP#V0 through R5F100AGASP#V0) share identical pinouts and mechanical footprint (PLSP0030JB-B). This allows direct substitution within the same memory/peripheral configuration tier, provided software accounts for differences in flash size, RAM, and enabled peripherals - verified in the "Outline of Functions" section of the R01DS0131EJ0380 datasheet.
