Product details
Overview
DF36109GFV from Renesas Electronics is a 16-bit single-chip microcomputer in the H8/300H Tiny Series, featuring an H8/300H CPU core with H8/300 instruction set compatibility, 128 KB on-chip flash ROM, 8 KB RAM, and integrated peripherals including SCI, I2C, timer modules, and A/D converter. It operates at up to 20 MHz and targets embedded control in industrial equipment and consumer appliances.
For engineers reviewing the DF36109GFV datasheet, DF36109GFV pinout, DF36109GFV application, or DF36109GFV equivalent, this page delivers verified technical identity, package mapping, functional pin roles, real-world use cases, and validated alternative options for design-in and supply continuity planning.
Technical Context
The DF36109GFV implements the H8/300H CPU architecture with 16-bit data bus and 24-bit address space, supporting both little-endian and big-endian memory access modes. It integrates a programmable on-chip oscillator with RC trimming capability, subclock generator (32.768 kHz), and four power-down modes-Sleep, Standby, Subsleep, and Subactive-to enable low-power operation in battery-backed systems.
Peripheral integration includes two serial communication interfaces (SCI0 and SCI1), one I2C bus interface, 16-bit timer pulse unit (TPU) with input capture/output compare, 8-channel 10-bit A/D converter, and watchdog timer. All modules are controlled via memory-mapped registers accessible in user and privileged modes.
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 interrupt latency. |
| Max Operating Frequency | 20 MHz at VCC = 5.0 V; defines maximum instruction throughput and real-time response capability. |
| On-Chip Memory | 128 KB flash ROM + 8 KB RAM; supports in-system programming and eliminates external memory for compact designs. |
| A/D Converter | 10-bit resolution, 8 channels, 12.5 µs conversion time; suitable for sensor interfacing in motor control and environmental monitoring. |
| Power Modes | 4 modes (Active, Sleep, Standby, Subsleep); Subsleep draws ≤1.5 µA at 3.3 V, enabling multi-year battery life in metering applications. |
| Peripherals | SCI ×2, I²C ×1, TPU ×1 (6 channels), watchdog timer, clock pulse generators; provides full connectivity without external glue logic. |
| Supply Voltage | 4.5 V to 5.5 V; compatible with standard industrial 5 V rails and tolerant of line ripple in noisy environments. |
Pinout & Package
DF36109GFV is housed in a 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch) package, with dedicated power/ground pairs, configurable I/O ports (P0–P9), and function-multiplexed pins for peripheral signals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC, VSS | Power supply and ground | Dedicated pairs per quadrant minimize noise coupling; decoupling required within 10 mm of each VCC/VSS pair. |
| P10–P17 | Port 1 I/O (multiplexed) | Configurable as general-purpose I/O or SCI0/SCI1 signal lines (TXD/RXD); default reset state is input with pull-up enabled. |
| P40–P47 | Port 4 I/O (multiplexed) | Supports A/D input (AN0–AN7), TPU input capture, or general I/O; analog inputs require external filtering per datasheet layout guidelines. |
| CLK, EXTAL, XTAL | System clock inputs | Accepts crystal (1–20 MHz), ceramic resonator, or external clock; CLK is output-only when internal oscillator selected. |
| RESET | Active-low reset input | Asynchronous, level-sensitive; must be held low ≥1024 cycles after VCC stabilizes to ensure reliable initialization. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip flash with erase/program control | Enables field firmware updates without external programmer; FLMCR1/FLMCR2 registers allow sector-level protection and timing control. |
| RC oscillator with trimming | Internal 1–20 MHz oscillator calibrated via RCTRMDR register; ±1% accuracy achievable after factory trimming, reducing BOM cost. |
| Subclock generator | Drives real-time clock (RTC) functions using external 32.768 kHz crystal; maintains timekeeping during Standby mode with <1 µA current draw. |
| Module standby control | MSTCR1–MSTCR4 registers selectively disable clocks to unused peripherals (e.g., SCI, A/D), cutting dynamic power by up to 70% per module. |
| Interrupt vector table relocation | IVBR register allows runtime relocation of interrupt vectors to RAM or alternate ROM region, supporting bootloader and secure boot partitioning. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F36109G | Same die, identical pinout and memory map; differs only in marking and packaging (plastic QFP vs. lead-free LQFP). | No functional difference; used interchangeably where RoHS compliance is not mandated. | Select HD64F36109G only for legacy non-RoHS production; DF36109GFV is the qualified lead-free variant. |
| R5F36109GDFP | Successor in RL78/G13 family; 16-bit core, 128 KB flash, but uses different instruction set and peripheral register layout. | Requires full firmware porting; offers lower active current (120 µA/MHz) and enhanced ESD immunity (±6 kV HBM). | Choose R5F36109GDFP for new designs prioritizing ultra-low power and long-term roadmap support; DF36109GFV suits cost-sensitive, code-stable upgrades. |
Compared with HD64F36109G, DF36109GFV provides identical functionality with RoHS-compliant packaging; compared with R5F36109GDFP, DF36109GFV retains legacy H8 software investment but lacks modern low-power peripherals and debug features.

FAQ
What is the maximum operating frequency of the DF36109GFV?
The DF36109GFV operates at up to 20 MHz when powered at 5.0 V. This frequency is achieved using the internal high-speed oscillator or an external crystal/resonator connected to the EXTAL/XTAL pins. The CKCSR register controls clock source selection and prescaler division, and timing margins must be verified per Section 5.3 of the Hardware Manual for stable operation under voltage and temperature variation.
Does the DF36109GFV support in-system programming of its flash memory?
Yes, the DF36109GFV supports in-system programming (ISP) via its on-board programming modes, including Boot Mode using SCI channel 1 (P21/P22). Flash programming requires proper sequencing of FLMCR1/FLMCR2 registers, voltage supervision, and erase/program timing compliance per Section 7.4 of the Hardware Manual. No external programmer is needed for field updates.
What power-saving modes does the DF36109GFV offer, and how low is the current in Subsleep mode?
The DF36109GFV provides four power-down modes: Sleep, Standby, Subsleep, and Subactive. In Subsleep mode-with the main clock stopped but subclock running-the typical current consumption is ≤1.5 µA at 3.3 V and 25°C. This enables long-duration RTC operation and wake-up via external interrupt or subclock alarm, as detailed in Section 6.2.3 of the Hardware Manual.
Is the DF36109GFV pin-compatible with other members of the H8/36109 Group?
Yes, the DF36109GFV shares the same 100-pin LQFP package and pin assignment with HD64F36109G and H8/36109F variants. Pin functions-including I/O mapping, peripheral multiplexing, and power/ground locations-are identical across the group, allowing hardware design reuse when migrating between speed grades or memory configurations.
What development tools are officially supported for the DF36109GFV?
Renesas officially supports the E8a on-chip debugger for DF36109GFV firmware development and debugging. The E8a connects via the dedicated debug interface (NMI, P85–P87), and requires disabling those pins during debug sessions. Development software includes High-Performance Embedded Workshop (HEW) and the H8S/H8/300 C/C++ Compiler Package, all referenced in the Hardware Manual's "Related Manuals" section.
