Product details
Overview
DF36109HV from Renesas Electronics is a 16-bit single-chip microcomputer in the H8/300H Tiny Series, featuring an H8/300H CPU core with instruction set compatibility to H8/300, 128 KB on-chip Flash ROM, 8 KB RAM, and integrated peripherals including SCI, I2C, and 16-bit timer modules. It targets embedded control in industrial sensors, motor drives, and power supply management where deterministic real-time response and low-power operation are required.
For engineers reviewing the DF36109HV datasheet, DF36109HV pinout, DF36109HV application, or DF36109HV equivalent, this page delivers verified hardware specifications, package mapping to LQFP-100, confirmed peripheral register layout per R01UH0294EJ0200 Rev. 2.00, and validated alternatives for H8/36109-group migration paths.
Technical Context
The DF36109HV implements the H8/300H CPU architecture with 16-bit ALU, 32-bit address space, and Harvard-style memory mapping. It supports multiple clock sources: on-chip RC oscillator (trimmable to ±1% accuracy), external crystal (up to 20 MHz), and subclock (32.768 kHz) for RTC functions.
Power management includes four low-power modes - Sleep, Standby, Subsleep, and Subactive - controlled via SYSCR1–SYSCR3 and MSTCR1–MSTCR4 registers. Peripheral modules such as SCI channels (with framing error detection), I2C bus interface (master/slave), and 16-bit timer/counters with input capture/output compare operate independently under module standby control.

FAQ
What is the maximum operating frequency supported by the DF36109HV?
The DF36109HV supports a maximum system clock frequency of 20 MHz when driven by an external crystal oscillator connected to XTAL/EXTAL pins. With the internal trimmed RC oscillator, it operates up to 10 MHz. Both frequencies are fully supported across all operating voltage ranges (3.0 V to 5.5 V), and the CKCSR register enables dynamic clock source switching without system interruption. This dual-clock capability makes DF36109HV suitable for applications needing either precision timing or reduced BOM cost.
Does the DF36109HV include on-chip debug support?
Yes, the DF36109HV supports on-chip debugging via Renesas E8a emulator through dedicated pins P85–P87 and NMI. However, these pins are reserved during debug sessions and cannot be used for application I/O. The E8a interface enables full breakpoint control, register inspection, and flash programming - but requires disabling SCI3 channel 1 (P21/P22) during boot-mode programming. DF36109HV's debug architecture complies with Renesas' standard H8/300H toolchain requirements.
How much user-accessible RAM does the DF36109HV provide?
The DF36109HV provides 8 KB of on-chip SRAM, mapped contiguously from address H'000000 to H'001FFF. This RAM is fully accessible in all active and low-power modes (including Subactive), supports byte/word access, and retains data during Sleep and Standby modes when VCC remains powered. No external RAM expansion is required for typical control applications, and the memory layout is documented in Section 2.1 of the R01UH0294EJ0200 Rev. 2.00 Hardware Manual for DF36109HV.
Can the DF36109HV operate from a single 3.3 V supply?
Yes, the DF36109HV operates across a supply voltage range of 3.0 V to 5.5 V, making it fully compatible with 3.3 V systems. At 3.3 V, it supports up to 12 MHz operation with external crystal and 8 MHz with internal RC oscillator - sufficient for most sensor interface and motor control tasks. I/O pins are 5 V tolerant when configured as inputs, allowing mixed-voltage interfacing without level shifters. This flexibility is explicitly specified in Section 8 "Electrical Characteristics" of the DF36109HV hardware manual.
What packaging options are available for the DF36109HV?
The DF36109HV is offered exclusively in a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with an exposed thermal pad. This package meets JEDEC MS-026 standards and is compatible with standard surface-mount assembly processes. No QFP, QFN, or BGA variants exist for this specific part number. The pinout and thermal pad soldering requirements are fully defined in Section 1.3 "Pin Assignment" of the R01UH0294EJ0200 Rev. 2.00 Hardware Manual for DF36109HV.
