Product details
Overview
R5F101EEANA#20 from Renesas is a 32-bit RL78/G13 microcontroller with 48 KB flash memory, 3 KB RAM, and no data flash, housed in a 40-pin HWQFN (6 × 6 mm, 0.5-mm pitch) package. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and supports ultra-low-power modes including STOP (0.57 μA) and HALT, targeting battery-powered sensor nodes and industrial control interfaces.
For engineers reviewing the R5F101EEANA#20 datasheet, R5F101EEANA#20 pinout, R5F101EEANA#20 application, or R5F101EEANA#20 equivalent, key selection criteria include its 40-pin HWQFN footprint, absence of on-chip data flash, -40°C to +85°C industrial temperature grade (D), and integrated 10-bit ADC with 26-channel analog input capability.
Technical Context
The R5F101EEANA#20 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). Its memory map spans 1 MB address space, with general-purpose register banks enabling efficient context switching in real-time interrupt handling.
It integrates peripheral subsystems including up to 16 channels of 16-bit timer, one real-time clock with calendar/alarm functions, UART/LIN-capable serial interfaces (2–4 channels), and an 8/10-bit A/D converter with internal 1.45 V reference and temperature sensor - all operating within the same 1.6–5.5 V supply range as the core.

FAQ
What is the operating temperature range for the R5F101EEANA#20?
The R5F101EEANA#20 is rated for industrial operation from -40°C to +85°C (D-grade), validated per Renesas specification R01DS0131EJ0380. This range supports deployment in factory automation, building controls, and outdoor sensor enclosures without derating.
Does the R5F101EEANA#20 include on-chip data flash memory?
No, the R5F101EEANA#20 does not include data flash memory. Per the RL78/G13 part numbering convention, the "101" prefix indicates no data flash, unlike "100" variants (e.g., R5F100EEANA#20) which integrate 4 KB. Code flash remains fully self-programmable.
Which package type and pin count does the R5F101EEANA#20 use?
The R5F101EEANA#20 uses a 40-pin HWQFN package (6 × 6 mm, 0.5-mm pitch), identified by the "NA" suffix and #20 packaging code. This matches the PWQN0040KC-A Renesas standard outline and supports reflow soldering per JEDEC J-STD-020.
Can the R5F101EEANA#20 operate from a 1.8 V supply?
Yes, the R5F101EEANA#20 supports operation from 1.6 V to 5.5 V, including 1.8 V nominal supplies. At 1.8 V, maximum frequency is reduced per datasheet limits, but all peripherals - including ADC, timers, and UART - remain functional with appropriate clock scaling.
How many analog input channels are available on the R5F101EEANA#20?
The R5F101EEANA#20 supports up to 26 analog input channels (ANI0–ANI25), confirmed in the RL78/G13 datasheet section 1.1 and pin configuration tables. Pin P147/ANI18 is explicitly listed for 40-pin variants, validating full channel access.
