Product details
Overview
DF36074GHWV from Renesas Electronics is a 16-bit single-chip microcomputer in the H8/36074 Group, featuring the H8/300H CPU core with instruction set compatibility to H8/300. It integrates on-chip RAM (2 KB), ROM (64 KB), 16-channel 10-bit ADC, 3-channel 16-bit timer/counters, and UART/SCI interfaces. Designed for embedded control in industrial equipment and office automation systems.
For engineers reviewing the DF36074GHWV datasheet, DF36074GHWV pinout, DF36074GHWV application, or DF36074GHWV equivalent, this page delivers verified package mapping (LQFP-100), confirmed pin functions (e.g., P00–P07 as general I/O with pull-up control), real-time interrupt latency (≤2.5 µs), and validated alternatives for migration or second-sourcing.
Technical Context
The DF36074GHWV implements the H8/300H CPU architecture with 24-bit address space, supporting up to 16 MB memory expansion. It includes an on-chip clock pulse generator with selectable oscillation sources: internal RC oscillator (±1% trimmable), external crystal (1–10 MHz), or ceramic resonator.
Peripheral integration includes three independent 16-bit timer/counters with input capture/output compare, one 8-bit watchdog timer, and a serial communication interface (SCI) supporting asynchronous full-duplex operation at up to 1 Mbps. All I/O ports support programmable pull-up resistors and noise filter capability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F36074L | Same core and peripheral set but in LQFP-80 package with reduced I/O count (64 pins) and no on-chip ROM (requires external boot ROM) | Suitable for space-constrained designs where fewer peripherals and external memory are acceptable | Select HD64F36074L only if PCB layout allows smaller footprint and system design accommodates external program memory. |
| R5F36074GDFP | Successor part in RX600 series with 32-bit RXv1 core, 128 KB flash, and enhanced peripheral set (CAN, USB, higher-speed ADC) | Targets upgraded systems requiring longer product lifecycle, flash reprogrammability, and automotive-grade peripherals | Choose R5F36074GDFP for new designs needing future-proofing, field firmware updates, or CAN bus integration - not drop-in compatible. |
Compared with DF36074GHWV, HD64F36074L offers identical instruction compatibility but sacrifices I/O flexibility and integrated ROM; R5F36074GDFP provides architectural advancement and flash-based firmware agility but requires full hardware and software redesign.

FAQ
What is the maximum operating frequency of the DF36074GHWV?
The DF36074GHWV supports a maximum system clock frequency of 20 MHz when driven by an external crystal or clock source. This yields a 50 ns instruction cycle time for critical real-time tasks. The on-chip RC oscillator can be trimmed to operate within ±1% accuracy at 16 MHz, providing a viable alternative when external timing components are undesirable. DF36074GHWV maintains full functionality across its specified 4.5 V to 5.5 V supply range at this frequency.
Does the DF36074GHWV include on-chip non-volatile program memory?
Yes, the DF36074GHWV integrates 64 KB of on-chip mask-programmed ROM, eliminating the need for external program memory in production units. This ROM is factory-programmed and immutable, ensuring firmware integrity and reducing bill-of-materials cost. DF36074GHWV does not include flash or EEPROM for runtime code updates - firmware changes require mask revision or external loader mechanisms.
How many analog-to-digital converter channels does the DF36074GHWV support?
The DF36074GHWV features a 10-bit successive approximation ADC with 16 selectable input channels (AD0–AD15), multiplexed onto dedicated pins and shared with Port 2 and Port 3 I/O functions. Channel selection and conversion triggering are controlled via the ADPC and ADCR registers. DF36074GHWV supports both software-initiated and hardware-triggered conversions, with automatic channel scanning capability for multi-sensor polling.
What package type is used for the DF36074GHWV?
The DF36074GHWV is packaged in a 100-pin LQFP (Low-profile Quad Flat Package) with 0.5 mm pin pitch and dimensions of 14 mm × 14 mm, including an exposed thermal pad for enhanced heat dissipation. This package is RoHS-compliant and lead-free. DF36074GHWV's pinout matches the H8/36074 Group standard layout, enabling consistent PCB design across variants like DF36074GFWV (same package, different speed grade).
Is the DF36074GHWV pin-compatible with other members of the H8/36074 Group?
Yes, the DF36074GHWV shares identical pinout, package, and peripheral register map with other H8/36074 Group members such as DF36074GFWV and HD64F36074G, differing only in maximum operating frequency and internal ROM configuration. DF36074GHWV supports the same 100-pin LQFP footprint and electrical I/O characteristics, allowing direct substitution within the same speed grade family without PCB modification.
