Product details
Overview
R5F104ECANA#20 from Renesas is a 40-pin HWQFN-packaged RL78/G14 16-bit microcontroller with 48 KB flash, 5.5 KB RAM, and 4 KB data flash, operating from 1.6–5.5 V. It delivers 44 DMIPS at 32 MHz, features ultra-low-power HALT/STOP/SNOOZE modes (66 μA/MHz active, 0.60 μA RTC+LVD), and integrates 10-bit ADC (16 channels), UART/SPI/I²C interfaces, RTC, and on-chip oscillators for industrial sensor control and motor drive applications.
For engineers reviewing the R5F104ECANA#20 datasheet, R5F104ECANA#20 pinout, R5F104ECANA#20 application, or R5F104ECANA#20 equivalent, key selection criteria include its 40-pin HWQFN-0.5 mm pitch package, 48 KB code flash with self-programming support, 10-bit ADC input count, real-time clock calendar function, and compatibility with Renesas CS+ and e² studio development tools.
Technical Context
The R5F104ECANA#20 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 supports multiply/divide/accumulate instructions and a 1 MB address space with four register banks.
Peripheral integration includes an Event Link Controller (ELC) for hardware-triggered peripheral chaining, Data Transfer Controller (DTC) with block/repeat transfer modes, and background operation (BGO) for concurrent data flash rewriting and program execution - enabling seamless firmware updates without halting real-time tasks.

FAQ
What is the maximum operating frequency and power consumption of the R5F104ECANA#20?
The R5F104ECANA#20 operates up to 32 MHz with 44 DMIPS performance and consumes 66 μA per MHz in active mode. In STOP mode with only RTC and LVD active, it draws just 0.60 μA - verified per Renesas R01DS0053EJ0370 datasheet Section 1.1. This makes R5F104ECANA#20 ideal for battery-critical applications like wireless sensor nodes where multi-year operation is required.
Does the R5F104ECANA#20 support in-system programming and secure firmware updates?
Yes, the R5F104ECANA#20 supports full in-system programming via its on-chip debug interface and includes boot swapping, flash shield window, and block erase prohibition for secure firmware updates. These features enable field upgrades without external programmers and prevent unauthorized access to protected code regions - all confirmed in the R5F104ECANA#20's flash memory section (Section 1.1, "Code Flash Memory") of the official datasheet.
How many analog input channels and what ADC resolution does the R5F104ECANA#20 provide?
The R5F104ECANA#20 integrates a 10-bit successive-approximation ADC with 16 analog input channels (ANI0–ANI15), plus dedicated AVREFP/AVREFM pins for precision reference. It also includes an internal 1.45 V reference and on-die temperature sensor - specifications explicitly listed in the "A/D Converter" subsection of the R01DS0053EJ0370 datasheet. No external reference IC is required for typical sensor measurement accuracy.
What serial communication interfaces are available on the R5F104ECANA#20?
The R5F104ECANA#20 provides 3 UART/LIN channels, up to 8 CSI (SPI-compatible) channels, and up to 10 I²C channels - all configurable via peripheral I/O redirection registers. The CSI interface supports master/slave modes and is electrically compatible with standard SPI peripherals. These capabilities are documented in the "Serial Interfaces" section of the RL78/G14 datasheet and validated for the R5F104EC series.
Is the R5F104ECANA#20 pin-compatible with other RL78/G14 variants in the 40-pin HWQFN package?
Yes, all RL78/G14 40-pin HWQFN variants - including R5F104EAANA#20, R5F104ECANA#20, R5F104EDANA#20, and R5F104EEANA#20 - share identical pinout, electrical characteristics, and package dimensions (PWQN0040KD-A). This allows hardware reuse across memory variants, as confirmed in Table 1-1 and Figure 1-1 of the R01DS0053EJ0370 datasheet.
