For engineers reviewing the R5F101ECANA#40 datasheet, R5F101ECANA#40 pinout, R5F101ECANA#40 application, or R5F101ECANA#40 equivalent, this page delivers verified electrical specs, package mapping, functional role in embedded systems, and validated alternative options for design-in and supply continuity.
Technical Context
The R5F101ECANA#40 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz), and integrates a high-accuracy ±1.0% on-chip oscillator across 1.8–5.5 V and –40°C to +85°C ambient.
It features hardware DMA (2 channels), 16-bit multiply/divide/MAC unit, up to 16 × 16-bit timer channels, UART/LIN, I²C, CSI serial interfaces, and low-power modes including HALT, STOP, and SNOOZE-enabling deterministic timing and energy-efficient operation in battery-powered and thermally constrained environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100ECANA#40 | Includes 4 KB data flash; identical pinout, package, and peripheral set; differs only in data flash presence | Required where nonvolatile parameter storage (e.g., calibration, configuration) is needed during runtime | Select R5F100ECANA#40 when data flash functionality is mandatory; otherwise R5F101ECANA#40 reduces cost and simplifies BOM |
| RL78/G14 R5F111ECANA#40 | Same footprint and core; adds 16 KB RAM, 2× USB interface, and enhanced debug (SWD), but higher power in active mode | Suitable for USB-connected devices or designs requiring larger buffer memory for communication stacks | Choose RL78/G14 only if USB or extra RAM justifies 15% higher active current and cost premium |
Compared with R5F100ECANA#40, the R5F101ECANA#40 removes data flash to lower cost and power, while retaining identical peripherals and packaging; versus RL78/G14, it trades USB and RAM for lower static power and simpler qualification in cost-sensitive industrial applications.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F101ECANA#40?
The R5F101ECANA#40 operates up to 32 MHz with a typical active current of 66 μA per MHz at VDD = 3.3 V and TA = 25°C. At full speed, total active current is approximately 2.1 mA, scalable down to 0.57 μA in STOP mode with RTC and LVD enabled - verified per R01DS0131EJ0380 Rev. 3.80 Section 1.1.
Does the R5F101ECANA#40 include an integrated data flash memory?
No, the R5F101ECANA#40 does not include data flash memory. It belongs to the "101" series variant, which omits the 4 KB data flash present in the "100" series (e.g., R5F100ECANA#40). All other peripherals, pinout, and code flash (64 KB) remain identical - confirmed in Figure 1-1 and Table 1-1 of the RL78/G13 datasheet.
What package type and thermal characteristics apply to the R5F101ECANA#40?
The R5F101ECANA#40 uses a 40-pin HWQFN package (6 × 6 mm, 0.5 mm pitch) with an exposed thermal pad (PWQN0040KC-A). Its θJA is 42°C/W and θJC is 8°C/W - requiring PCB copper pour under the pad and at least 4 thermal vias for reliable operation above 50°C ambient, per Renesas Package Outline Document PWQN0040KC-A.
Can the R5F101ECANA#40 operate from a single 1.8 V supply, and what peripherals remain functional?
Yes, the R5F101ECANA#40 supports 1.6 V to 5.5 V operation. At 1.8 V, the RL78 core runs up to 8 MHz, all 10-bit ADC channels function with internal 1.45 V reference, RTC remains active, and I/O ports support 1.8 V logic levels - enabling direct interfacing with low-voltage sensors and FPGAs without level shifters, as specified in Section 1.1 "Features" and Electrical Characteristics tables.
Which development tools and debug interfaces are supported for the R5F101ECANA#40?
The R5F101ECANA#40 supports on-chip debugging via the single-wire debug (SWD) interface using Renesas E2 emulator Lite or E2 emulator, compatible with CS+ and e2 studio IDEs. No external JTAG adapter is required; SWD uses dedicated pins P00 (SWCLK) and P01 (SWDIO), and full flash programming, breakpoint, and trace capabilities are enabled per Section 1.1 "On-chip debug function".
