Product details
Overview
DF36014FPV from Renesas Electronics is a 16-bit single-chip microcomputer in the H8/36014 Group, featuring the H8/300H CPU core with instruction compatibility to the H8/300. It integrates on-chip ROM (128 KB), RAM (8 KB), and peripheral modules including SCI, I2C, timers, and ADC - designed for embedded control in industrial equipment and office automation systems.
For engineers reviewing the DF36014FPV datasheet, DF36014FPV pinout, DF36014FPV application, or DF36014FPV equivalent, key selection criteria include its 16-bit H8/300H architecture, 128 KB on-chip flash ROM, 8 KB RAM, 5 V operation, and support for on-board programming via boot mode using SCI3 channel 1.
Technical Context
The DF36014FPV implements the H8/300H CPU core with a 16-bit data bus and 24-bit address space, supporting up to 16 MB addressing. It includes a system clock generator with crystal/ceramic resonator or external clock input options, and three prescaler units (S, P, Q) for flexible peripheral clock derivation.
Power management features include Sleep, Standby, and Subsleep modes controlled by SYSCR1/SYSCR2 and MSTCR1/MSTCR2 registers. The device supports on-chip flash programming/erasing in user program mode and boot mode, with dedicated FLMCR1/FLMCR2 and EBR1 registers for flash control and block erase configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | H8/300H 16-bit RISC core, instruction-compatible with H8/300; enables legacy code reuse and deterministic real-time execution. |
| ROM Size | 128 KB on-chip flash memory; supports in-system programming and secure boot-mode programming via SCI3. |
| RAM Size | 8 KB on-chip RAM; sufficient for stack, variables, and real-time buffer handling without external memory. |
| Supply Voltage | 4.5 V to 5.5 V operation; compatible with standard 5 V industrial logic families and simplifies power supply design. |
| Max Operating Frequency | 20 MHz CPU clock (with 40 MHz internal bus clock via prescaler S); delivers ~12.5 MIPS performance for mid-complexity control tasks. |
| I/O Pins | 80-pin LQFP package with 64 programmable I/O pins; supports multiple peripheral functions multiplexed on port pins (e.g., P21/P22 as SCI3 RX/TX). |
| ADC | 8-channel 10-bit successive-approximation ADC with internal reference; enables direct sensor interface without external reference or signal conditioning. |
Pinout & Package
DF36014FPV is housed in an 80-pin LQFP (14 mm × 14 mm, 0.65 mm pitch) package with exposed thermal pad. Pin assignments follow the H8/36014 Group standard layout, including dedicated reset (RES), NMI, and clock input (XIN/XOUT) terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RES | Active-low reset input | Asynchronous hardware reset; must be held low ≥100 ns after VCC stabilizes to ensure reliable initialization. |
| XIN / XOUT | Crystal/resonator connection | Supports 1–20 MHz crystal or ceramic resonator; internal oscillator circuit eliminates need for external oscillator IC. |
| P21 / P22 | SCI3 RXD / TXD (multiplexed) | Enable UART-based on-board programming in boot mode; no external level shifter required for 5 V TTL-level communication. |
| VSS, VCC | Ground and power supply | Dual VCC/VSS pairs per side reduce noise coupling; thermal pad enhances thermal dissipation under continuous operation. |
| NMI | Non-maskable interrupt input | Reserved for on-chip emulator (E7/E8); not available for user application when debugging hardware is connected. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F36014G | Same die, identical electrical specs and pinout; differs only in marking and packaging (plastic QFP vs. lead-free FPV variant). | No functional difference; suitable for RoHS-compliant assembly where lead-free finish is mandatory. | Select HD64F36014G if lead-free reflow profile compliance is required; DF36014FPV uses standard SnPb finish. |
| R5F36614 | Successor in RL78/G13 family; 16-bit core, lower power (120 µA/MHz), but reduced ROM (128 KB same) and no H8 instruction compatibility. | Requires firmware porting due to ISA change; better for new ultra-low-power designs, not drop-in replacement. | Choose R5F36614 only for greenfield projects prioritizing energy efficiency over legacy code reuse. |
Compared with HD64F36014G, DF36014FPV offers identical functionality with standard finish; versus R5F36614, it preserves H8 software investment but consumes more active power - making DF36014FPV optimal for cost-sensitive, code-migration-focused industrial upgrades.

FAQ
What is the maximum operating frequency of the DF36014FPV?
The DF36014FPV supports a maximum CPU clock frequency of 20 MHz, with an internal bus clock up to 40 MHz derived via prescaler S. This enables approximately 12.5 million instructions per second (MIPS) performance, sufficient for real-time control loops in industrial and office automation applications. The DF36014FPV achieves this using an external crystal (up to 20 MHz) connected to XIN/XOUT or an external clock source.
Does the DF36014FPV support in-system programming?
Yes, the DF36014FPV supports in-system programming via its on-chip flash memory. It provides two operational modes: boot mode (using SCI3 pins P21/P22 for UART-based programming) and user program mode (for background programming during runtime). The DF36014FPV includes dedicated flash control registers (FLMCR1/FLMCR2) and erase block registers (EBR1) to manage write/erase cycles securely and reliably.
Is the DF36014FPV pin-compatible with other H8/36014 Group variants?
Yes, the DF36014FPV is pin-compatible with all members of the H8/36014 Group, including HD64F36014 and HD64F36014G, sharing the same 80-pin LQFP package and identical pin functions. Differences between variants are limited to marking, packaging finish (e.g., lead-free vs. SnPb), and minor quality grade labeling - not electrical or mechanical interface behavior. The DF36014FPV maintains full hardware interoperability within this group.
What debug tools are supported for the DF36014FPV?
The DF36014FPV is fully supported by Renesas' E7 and E8 on-chip emulators, which connect via dedicated debug pins and provide real-time trace, breakpoints, and register inspection. When using these tools, the NMI pin is reserved and unavailable for user interrupts, and memory areas H'7000–H'7FFF and H'F780–H'FB7F are inaccessible. The DF36014FPV's hardware debug infrastructure enables rapid firmware validation without requiring external JTAG adapters.
What are the power management capabilities of the DF36014FPV?
The DF36014FPV implements three low-power modes: Sleep (CPU stopped, peripherals active), Standby (all clocks halted except RTC), and Subsleep (selected modules active at reduced clock rate). Current consumption drops to ≤10 µA in Standby mode. These modes are controlled via SYSCR1/SYSCR2 and MSTCR1/MSTCR2 registers, allowing fine-grained power gating. For battery-powered sensor nodes, the DF36014FPV's Subsleep mode enables periodic wake-up and ADC sampling while maintaining µA-level average current draw.
