Product details
Overview
R5F101AEASP#V0 from Renesas is a 32-bit RL78/G13 microcontroller with 64 KB flash memory, 4 KB data flash, and 3 KB RAM, operating at up to 32 MHz with 41 DMIPS performance. It features ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), 10-bit A/D converter (26 channels), real-time clock, and UART/I²C/CSI interfaces - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101AEASP#V0 datasheet, R5F101AEASP#V0 pinout, R5F101AEASP#V0 application, or R5F101AEASP#V0 equivalent, key selection criteria include its 40-pin LSSOP package, absence of on-chip data flash (per "101" family designation), -40°C to +85°C industrial temperature grade, and support for SNOOZE mode wake-up via peripheral interrupts.
Technical Context
The R5F101AEASP#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 integrates a 12-bit interval timer, calendar-based real-time clock with alarm and correction, and watchdog timer driven by dedicated low-speed oscillator.
Power management includes HALT, STOP, and SNOOZE modes; voltage detection (14-level LVD) supports interrupt or reset; and DMA controller provides 2-channel transfers between SFR and RAM in just 2 clocks per 8/16-bit operation. The high-accuracy on-chip oscillator offers ±1.0% stability across 1.8–5.5 V and -20 to +85°C.
Key Specifications
