Product details
Overview
DF36109GHV from Renesas Electronics is a 16-bit single-chip microcomputer in the H8/300H Tiny Series, featuring the 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, and 16-bit timer/counters. It targets embedded control in industrial equipment, test instrumentation, and office automation systems.
For engineers reviewing the DF36109GHV datasheet, DF36109GHV pinout, DF36109GHV application, or DF36109GHV equivalent, this page delivers verified technical identity, package mapping to LQFP-100, confirmed pin functions, real-time clock support via subclock generator, and validated alternatives for legacy H8-based system maintenance and redesign.
Technical Context
The DF36109GHV implements the H8/300H CPU core with 16-bit data bus and 24-bit address space, supporting up to 16 MB addressing. It integrates a programmable on-chip RC oscillator (trimmable ±1% at 20 MHz), external crystal support (1–20 MHz main clock, 32.768 kHz subclock), and four power-down modes (Sleep, Standby, Subsleep, Subactive) controlled via SYSCR1–SYSCR3 registers.
Peripheral modules include two serial communication interfaces (SCI1/SCI3), an I2C bus interface, 16-bit timer/counters with input capture/output compare, and 8-channel 10-bit ADC. All peripherals are memory-mapped and accessible via dedicated register sets defined in the Hardware Manual R01UH0294EJ0200.

| CLKOUT | System clock output | Drives external logic or test equipment at 1/2 or 1/4 system clock frequency - used for synchronization and debug visibility |
| P00–P07 | Port 0 bidirectional I/O | Configurable as general-purpose I/O or alternate functions (e.g., SCI1 TXD/RXD, timer input capture) - supports multiplexed peripheral routing |
| P20–P27 | Port 2 bidirectional I/O | Includes SCI3 TXD/RXD (P21/P22), I2C SCL/SDA (P24/P25), and ADC input channels (P26/P27) - enables compact mixed-signal interface design |
| RESET | Active-low reset input | Asynchronous reset assertion clears CPU state and initializes all peripheral registers - must be held low ≥1024 cycles after power stabilization |
Key Features
| Feature | Design Value |
|---|---|
| On-chip RC oscillator with trimming | Factory-trimmed 20 MHz RC oscillator with ±1% accuracy over temperature; adjustable via RCTRMDR register - eliminates need for external crystal in cost-sensitive applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F36109GDFP | Same H8/36109 core, identical Flash/RAM, but in 100-pin QFP (no exposed pad); lacks LQFP thermal performance | Suitable for non-thermally constrained PCBs where reflow profile limits LQFP use | Select when thermal management is handled externally or ambient temperature remains <60°C |
| HD64F36109G | Pin-compatible predecessor with identical register map and instruction set; same 128 KB Flash but no factory RC trim calibration data | Requires external crystal for production-grade timing; not recommended for new designs requiring guaranteed oscillator accuracy | Choose only for drop-in replacement in legacy systems where existing crystal infrastructure is retained |
Compared with DF36109GHV, R5F36109GDFP offers identical functionality in a less thermally efficient package, while HD64F36109G lacks calibrated RC oscillator support - making DF36109GHV the optimal choice for new designs needing robust, crystal-free timing and thermal reliability.

FAQ
What is the maximum operating frequency of the DF36109GHV?
The DF36109GHV supports a maximum system clock frequency of 20 MHz, achievable either via its factory-trimmed on-chip RC oscillator or an external crystal/resonator connected to XTAL/EXTAL pins. This frequency enables deterministic real-time execution with interrupt response times under 50 µs, as confirmed in Section 5.3.3 of the Hardware Manual R01UH0294EJ0200.
Does the DF36109GHV support in-system programming of its Flash memory?
Yes, the DF36109GHV supports in-system programming of its 128 KB Flash memory using boot-mode programming via the SCI3 interface (P21/P22), requiring only a single 5 V supply. This capability is documented in Section 7.3.1 of R01UH0294EJ0200 and eliminates the need for external programmers in field firmware updates.
What power-saving modes does the DF36109GHV offer?
The DF36109GHV implements four hardware-controlled power-down modes: Sleep, Standby, Subsleep, and Subactive - each with distinct clock domain gating and wake-up sources. Section 6.2 of R01UH0294EJ0200 specifies that Standby mode draws <5 µA while retaining RAM and RTC operation, making DF36109GHV suitable for battery-backed applications.
Is the DF36109GHV pin-compatible with other H8/36109 family members?
Yes, the DF36109GHV shares identical pin assignment and electrical characteristics with other 100-pin variants in the H8/36109 Group, including HD64F36109G and R5F36109GDFP. Pin compatibility is verified in Section 1.3 (Pin Assignment) of R01UH0294EJ0200, ensuring PCB reuse across qualified variants.
What peripheral interfaces are integrated into the DF36109GHV?
The DF36109GHV integrates two serial communication interfaces (SCI1 and SCI3), an I2C bus interface, eight 16-bit timer/counters with PWM and input capture, and an 8-channel 10-bit ADC. These peripherals are memory-mapped and fully described in Sections 2–7 of R01UH0294EJ0200, enabling self-contained control without external support chips.
