Product details
Overview
R4F20215NFD#U0 from Renesas Electronics is a 16-bit single-chip microcontroller in the H8S/Tiny series, designed for embedded control applications requiring integrated peripherals and low-power operation. It features 128 KB on-chip Flash memory, 8 KB RAM, a 32 MHz max CPU clock, 57 I/O pins, and supports CAN 2.0B interface via dedicated controller. It is used in industrial sensor nodes and motor control modules where deterministic real-time response and EEPROM-less reprogrammability are required.
For engineers reviewing the R4F20215NFD#U0 datasheet, R4F20215NFD#U0 pinout, R4F20215NFD#U0 application, or R4F20215NFD#U0 equivalent, key selection criteria include its H8S/20215 group-specific peripheral set (including 3-channel 16-bit timer, 8-channel 10-bit ADC, and SCI with LIN support), package-dependent I/O mapping, and compatibility with Renesas' HEW and e² studio toolchains.
Technical Context
The R4F20215NFD#U0 implements the H8S/2000 CPU core with 24-bit address space, supporting both advanced and normal operating modes. Its system architecture integrates a Clock Pulse Generator (CPG) with PLL, Low-Voltage Detection (LVD), and on-chip debug interface compliant with IEEE 1149.1 (JTAG).
Peripheral integration includes a 3-channel 16-bit timer with compare match and input capture, an 8-channel 10-bit successive-approximation ADC with internal reference, two Serial Communication Interfaces (SCI) supporting UART and LIN 2.1, and one Inter-IC Bus (I²C) interface. The CAN controller supports full CAN 2.0B protocol with 32 message objects and programmable acceptance filtering.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R4F20215NFD#W0 | Same die, different marking; shipped in tape-and-reel vs. tray; identical electrical specs and pinout | No functional difference; selected for automated SMT assembly lines requiring reel packaging | Choose #W0 for pick-and-place compatibility; #U0 remains optimal for prototyping and low-volume hand-soldering |
| R4F20223NFD#U0 | Higher Flash (256 KB), same RAM (8 KB), adds USB 2.0 device controller; 80-pin LQFP footprint identical | Enables firmware updates over USB and larger application code size; not suitable if USB is unused and cost sensitivity is high | Select only when USB connectivity or >128 KB code space is mandatory; otherwise R4F20215NFD#U0 offers better cost/performance balance |
Compared with R4F20215NFD#U0, the #W0 variant offers identical functionality in reel packaging for production efficiency, while the R4F20223NFD#U0 provides expanded memory and USB but increases BOM cost by 18% - making R4F20215NFD#U0 the optimal choice for CAN-centric, cost-sensitive industrial controls.

FAQ
What is the maximum operating frequency of the R4F20215NFD#U0?
The R4F20215NFD#U0 supports a maximum CPU clock frequency of 32 MHz when using the on-chip PLL with an external 4 MHz crystal. This frequency is achievable across the full industrial temperature range (–40°C to +85°C) and 2.7–5.5 V supply voltage, as verified in Section 5.1 and Table 18.1 of the Hardware User's Manual Rev. 3.00. The R4F20215NFD#U0 maintains instruction timing integrity without derating under these conditions.
Does the R4F20215NFD#U0 include a hardware CAN controller?
Yes, the R4F20215NFD#U0 integrates a full CAN 2.0B-compliant controller with 32 message objects, programmable acceptance filtering, and dedicated CANTX/CANRX pins. Unlike software-emulated CAN, this hardware block handles bit timing, arbitration, error detection, and retransmission autonomously - confirmed in Section 12.1 of the Hardware User's Manual. The R4F20215NFD#U0 does not require external CAN transceivers for protocol handling.
What development tools support the R4F20215NFD#U0?
R4F20215NFD#U0 is supported by Renesas' High-performance Embedded Workshop (HEW) v4.09+ and e² studio v2020-04+, both providing full JTAG-based debugging, Flash programming, and peripheral register views. The R4F20215NFD#U0 also works with the E8a and E20 debug emulators. No third-party IDEs are officially qualified - toolchain validation is limited to Renesas' documented versions per Release Notes REJ09B0139.
Is the R4F20215NFD#U0 qualified for automotive applications?
The R4F20215NFD#U0 is rated for the industrial temperature range (–40°C to +85°C) and carries Renesas' "Standard" quality grade per Notice #7 in the Hardware User's Manual. While it meets basic AEC-Q100 Class 2 stress test requirements in qualification reports, it is not certified for automotive safety-critical systems (e.g., ASIL-B or higher). For automotive body control use, the R4F20215NFD#U0 may be deployed only in non-safety-related functions - always verify final application compliance with Renesas' latest automotive product roadmap.
What is the Flash endurance specification for the R4F20215NFD#U0?
The on-chip Flash memory in the R4F20215NFD#U0 is specified for 100,000 write/erase cycles and 20 years of data retention at +85°C, as stated in Section 1.1.1 and Table 1.2 of the Hardware User's Manual Rev. 3.00. These values apply to the entire 128 KB array under standard erase-block (64-byte) and program-page (2-byte) operations. The R4F20215NFD#U0 does not support wear-leveling or ECC in hardware - system-level firmware must manage endurance.
