For engineers reviewing the R5F100ECANA#40 datasheet, R5F100ECANA#40 pinout, R5F100ECANA#40 application, or R5F100ECANA#40 equivalent, key selection criteria include its 40-pin HWQFN (6 × 6 mm, 0.5 mm pitch) package, 64 KB code flash with self-programming and boot swap, 10-bit ADC with internal reference and temperature sensor, and support for UART/LIN, I²C, and CSI serial interfaces in low-voltage embedded control designs.

Technical Context

The R5F100ECANA#40 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates on-chip power management including POR, LVD with 14 selectable levels, and multiple low-power states (HALT, STOP, SNOOZE).

Its peripheral set includes 8–16 channels of 16-bit timer, one 12-bit interval timer, one real-time clock with calendar and alarm, one watchdog timer, and DMA controller with 2/4 channels supporting 2-clock transfers between SFR and RAM - all optimized for deterministic timing in resource-constrained edge nodes.

FAQ

What is the maximum operating frequency and corresponding performance of the R5F100ECANA#40?

The R5F100ECANA#40 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its RL78 CPU core supports variable instruction execution time - from 0.03125 μs at 32 MHz to 30.5 μs at 32.768 kHz - enabling precise trade-offs between speed and power consumption in real-time control loops. This makes the R5F100ECANA#40 well-suited for deterministic timing-critical tasks in industrial and metering applications.

Does the R5F100ECANA#40 support in-system programming and firmware updates without external hardware?

Yes, the R5F100ECANA#40 supports full in-system programming via its on-chip debug interface and self-programming capability. It includes boot swap functionality and flash shield window protection, allowing secure over-the-air or field-based firmware updates without requiring external programmers. The R5F100ECANA#40 also enables background operation (BGO) during data flash rewriting, ensuring uninterrupted program execution - critical for reliable operation in unattended remote deployments.

What analog features are integrated into the R5F100ECANA#40, and how are they applied in sensor systems?

The R5F100ECANA#40 integrates a 10-bit ADC with up to 26 analog input channels, internal 1.45 V reference voltage, and an on-chip temperature sensor. These features allow direct connection of resistive sensors (e.g., RTDs, thermistors), voltage-output transducers, and battery monitoring circuits without external references or signal conditioning. In sensor systems, this reduces bill-of-materials cost and improves measurement consistency - especially valuable in compact, battery-powered devices like environmental monitors where the R5F100ECANA#40 serves as both signal conditioner and controller.

How does the low-power capability of the R5F100ECANA#40 benefit battery-operated applications?

The R5F100ECANA#40 achieves 0.57 μA current consumption in STOP mode with only RTC and LVD active - enabling multi-year operation on standard coin cells. Combined with HALT and SNOOZE modes, it allows dynamic power scaling based on event triggers (e.g., timer wake-up, external interrupt, or ADC threshold). For battery-operated applications such as wireless sensor nodes or portable medical devices, this translates directly into extended maintenance intervals and higher system reliability - a key advantage of the R5F100ECANA#40 over higher-power alternatives.

Is the R5F100ECANA#40 pin-compatible with other RL78/G13 variants in the same package?

Yes, the R5F100ECANA#40 shares identical pinout and electrical characteristics with all other 40-pin HWQFN RL78/G13 variants (e.g., R5F100EDANA#40, R5F100EEANA#40), enabling drop-in replacement within the same memory and feature tier. Pin compatibility is guaranteed across the R5F100x-ANA series in the PWQN0040KC-A/PWQN0040KD-A package variants, simplifying design reuse and migration paths. However, functional differences (e.g., flash size, data flash presence) must be verified in software configuration to ensure full compatibility of the R5F100ECANA#40 in existing designs.
