Product details
Overview
R5F101AEASP#10 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 (41 DMIPS), featuring 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 multiple serial interfaces (UART, I²C, CSI) - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101AEASP#10 datasheet, R5F101AEASP#10 pinout, R5F101AEASP#10 application, or R5F101AEASP#10 equivalent, key selection criteria include its 40-pin HWQFN package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (D suffix), and integrated low-voltage detection with 14-level programmable reset thresholds.
Technical Context
The R5F101AEASP#10 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting variable instruction execution time (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It integrates a 12-bit interval timer, 16-bit timer array (12 channels), watchdog timer with dedicated low-speed oscillator, and background operation for data flash rewriting.
Its peripheral set includes UART/LIN-capable serial channels (2–4), simplified I²C (3–10 channels), CSI (2–8 channels), 10-bit A/D converter with internal 1.45 V reference and temperature sensor, and DMA controller with 2/4 channels enabling 2-clock transfers between SFR and RAM.

Yes, the R5F101AEASP#10 integrates a full-featured real-time clock (RTC) with calendar support (99-year range), alarm interrupt capability, and hardware clock correction - all operational in STOP mode with only 0.57 μA current draw, enabling precise timekeeping in battery-backed applications.
What package type and pin count does the R5F101AEASP#10 use?
The R5F101AEASP#10 uses a 40-pin HWQFN package (6 × 6 mm, 0.5-mm pitch), as confirmed by Renesas ordering code structure and datasheet Table 1-1. This compact, thermally efficient package supports reflow soldering and is rated MSL3 for standard handling.
How does the R5F101AEASP#10 achieve ultra-low power consumption?
The R5F101AEASP#10 achieves 66 μA/MHz active current and 0.57 μA STOP-mode current through RL78's optimized low-leakage process, multiple low-power modes (HALT, STOP, SNOOZE), and selective peripheral gating. Its on-chip LVD and POR further enhance reliability during voltage transients without external components.
Is the R5F101AEASP#10 qualified for industrial temperature operation?
Yes, the R5F101AEASP#10 is rated for -40°C to +85°C operation (industrial D grade), as indicated by the "D" in its full part number family classification and confirmed in Renesas RL78/G13 datasheet Section 1.1.
