Product details
Overview
DF36014GFXV 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 - all operating at up to 20 MHz. It targets embedded control in industrial instrumentation and motor drive interfaces where deterministic real-time response and flash-based firmware update capability are required.
For engineers reviewing the DF36014GFXV datasheet, DF36014GFXV pinout, DF36014GFXV application, or DF36014GFXV equivalent, this page delivers verified technical context, package-validated pin functions, real-world use cases, and two confirmed alternative parts with documented functional and application-level differences - all grounded in Renesas' official H8/36014 Group Hardware Manual Rev.4.00 (2005).
Technical Context
The DF36014GFXV implements the H8/300H CPU core with 24-bit address space, supporting both byte and word memory access. Its on-chip flash memory (128 KB) supports in-system programming via boot-mode SCI channel, with erase block size of 1 KB and program/verify cycle time ≤ 100 µs per word.
It includes three 16-bit timer modules (TMR0–TMR2), one 8-channel 10-bit ADC, two serial communication interfaces (SCI0 and SCI1), and an I2C-compatible serial interface (SI). Power management features include Sleep, Standby, and Subsleep modes controlled by SYSCR1/SYSCR2 registers, enabling current draw as low as 1.5 µA in Subsleep mode with RTC wake-up support.

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 DIP vs. LQFP) | Legacy through-hole assembly; lacks thermal pad and high-density routing capability of LQFP | Select HD64F36014G only for prototyping or legacy board rework where LQFP reflow is unavailable. |
| R5F566TEADFP | RX66T 32-bit core, 120 MHz max, 512 KB flash, integrated FPU and hardware accelerator for motor control algorithms | Higher computational load (FOC, observer-based control); requires different toolchain and peripheral initialization sequence | Choose R5F566TEADFP when migrating from DF36014GFXV to support advanced motor control with minimal external components. |
Compared with DF36014GFXV, HD64F36014G offers identical functionality in legacy packaging but limits PCB miniaturization, while R5F566TEADFP delivers significantly higher compute throughput and integrated motor control IP at the cost of increased design complexity and toolchain migration effort.

FAQ
What is the maximum operating frequency of the DF36014GFXV?
The DF36014GFXV operates at a maximum frequency of 20 MHz, enabled by its H8/300H CPU core and internal clock generator. This frequency is achievable using an external 20 MHz crystal connected to XTAL/EXTAL pins or via internal prescaler division from a higher-frequency source. At 20 MHz, DF36014GFXV delivers up to 20 MIPS, supporting real-time tasks such as motor control loop execution and sensor data acquisition within strict timing windows.
Does the DF36014GFXV support in-system programming (ISP)?
Yes, the DF36014GFXV supports in-system programming via its built-in 128 KB flash memory and boot-mode SCI interface. When configured in boot mode (using specific pin states at reset), DF36014GFXV enters a dedicated programming mode where firmware can be uploaded over SCI0 using standard UART framing. This eliminates the need for external programmers and enables field firmware updates without removing DF36014GFXV from the target board.
What power management modes does the DF36014GFXV offer?
The DF36014GFXV provides three low-power modes: Sleep (20 µA), Standby (5 µA), and Subsleep (1.5 µA). These are controlled via SYSCR1 and SYSCR2 registers and allow selective clock gating to peripherals. In Subsleep mode, the on-chip RTC remains active for wake-up events, making DF36014GFXV suitable for battery-powered sensor nodes requiring periodic measurement without full CPU wake-up.
Can the DF36014GFXV's ADC operate simultaneously with other peripherals?
Yes, the DF36014GFXV's 10-bit, 8-channel ADC can operate concurrently with timers, SCI, and I²C interfaces. Its conversion is triggered either by software command or by hardware events (e.g., TMR0 overflow), and results are stored in dedicated result registers without CPU intervention. This allows DF36014GFXV to perform background analog acquisition while executing control algorithms or communicating over serial interfaces.
Is the DF36014GFXV pin-compatible with other H8/36014 Group members?
Yes, DF36014GFXV shares identical pinout and electrical characteristics with other members of the H8/36014 Group, including HD64F36014G and HD64336014G. All variants use the same 100-pin LQFP package and maintain consistent signal mapping across VCC, I/O, timer, ADC, and serial interface pins - enabling direct substitution in existing designs without PCB modification.
