Product details
Overview
DF36054HV from Renesas Electronics is a 16-bit single-chip microcontroller in the H8/36054 Group, featuring the H8/300H CPU core with instruction set compatibility to H8/300, 128 KB on-chip ROM, 8 KB RAM, and integrated peripherals including SCI, I2C, timer units, and 80-pin PQFP package. It targets embedded control in industrial automation and instrumentation where deterministic real-time response and code density are critical.
For engineers reviewing the DF36054HV datasheet, DF36054HV pinout, DF36054HV application, or DF36054HV equivalent, this page delivers verified technical identity, validated pin functions, confirmed operating voltage (3.0–5.5 V), maximum frequency (20 MHz), and two documented alternative parts for functional migration paths.
Technical Context
The DF36054HV implements the H8/300H CPU architecture with 16-bit ALU, 32-bit internal data path, and Harvard-style memory organization. It supports multiple power-down modes-Sleep, Standby, Subsleep, and Subactive-with configurable module-level standby via MSTCR1/MSTCR2 registers.
Its clock system includes selectable oscillation sources (crystal, ceramic resonator, or external clock), programmable prescaler S, and system clock generator enabling flexible timing control. Peripheral integration includes three serial communication interfaces (SCI), one I2C bus interface, and eight 16-bit timer channels with input capture/output compare capability.

|---|---|
Use Scenario: Local control node collecting analog/digital sensor data and executing logic-based actuator commands in distributed automation systems. IC Role / Device Role / Timing Role: Central execution unit managing real-time task scheduling, serial sensor polling (via SCI/I²C), and deterministic GPIO output updates. Use Value: 20 MHz CPU throughput ensures sub-millisecond loop execution; 64 I/O pins support direct connection to field devices without external expanders. |
Use Scenario: Multi-sensor aggregation unit interfacing temperature, pressure, and flow transducers in harsh factory environments. IC Role / Device Role / Timing Role: Embedded host processor handling protocol translation (Modbus RTU over SCI), calibration compensation, and watchdog-monitored data forwarding. Use Value: Wide 3.0–5.5 V supply range tolerates industrial power fluctuations; integrated clock generator eliminates external oscillator BOM cost. |
| Programmable Power Supply Controller | Legacy Equipment Retrofit Module |
Use Scenario: Digital control core for adjustable DC power supplies requiring precise voltage/current regulation and protection sequencing. IC Role / Device Role / Timing Role: Real-time feedback controller using timer PWM outputs and ADC input (via compatible variant HD64F36054G with ADC; DF36054HV relies on external ADC). Use Value: On-chip flash enables field firmware updates; multiple SCI channels support simultaneous communication with front-panel UI and upstream master controller. |
Use Scenario: Drop-in replacement for obsolete 8/16-bit MCUs in aging test equipment, medical analyzers, or telecom line cards needing extended lifecycle support. IC Role / Device Role / Timing Role: Pin-compatible upgrade path (within H8/36054 family) preserving PCB layout while adding memory headroom and debug capability. Use Value: H8/300H instruction compatibility allows reuse of existing assembly/C firmware; E7/E8 emulator support simplifies validation of legacy code porting. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F36054G | Same core, same pinout, identical ROM/RAM, but includes 10-bit 8-channel ADC; requires different power sequencing for ADC reference | Required when analog sensing is integrated on MCU die; not suitable if only digital I/O and serial comms are needed | Select HD64F36054G only if on-chip ADC functionality is mandatory; DF36054HV avoids ADC-related design constraints and cost |
| H8/36057 | Higher memory configuration (256 KB ROM, 16 KB RAM), same peripheral set and package; upward-compatible instruction set | Used when firmware size exceeds 128 KB or additional RAM is required for buffering or multitasking stacks | Choose H8/36057 for future-proofing or larger application code; DF36054HV optimizes BOM cost where memory headroom is sufficient |
Compared with HD64F36054G and H8/36057, DF36054HV provides optimal balance of deterministic real-time performance, compact memory footprint, and minimal peripheral overhead-ideal for cost-sensitive, digitally focused control applications without analog front-end requirements.

FAQ
What is the maximum operating frequency of the DF36054HV?
The DF36054HV operates at a maximum system clock frequency of 20 MHz, delivering up to 20 MIPS performance. This frequency is achieved using an external crystal (up to 20 MHz), ceramic resonator, or external clock source connected to the CLK/EXTAL pins. The internal prescaler and clock generator allow flexible division for peripheral timing without compromising CPU throughput.
Does the DF36054HV include an analog-to-digital converter (ADC)?
No, the DF36054HV does not integrate an ADC. While some variants in the H8/36054 Group-such as HD64F36054G-include a 10-bit 8-channel ADC, the DF36054HV omits this peripheral to reduce cost and complexity for purely digital control applications. External ADCs must be used if analog signal acquisition is required.
Is the DF36054HV pin-compatible with other H8/36054 Group members?
Yes, the DF36054HV shares the same 80-pin PQFP package and pin assignment with all members of the H8/36054 Group, including HD64F36054 and HD64F36054G. This enables hardware reuse across variants-only firmware and external circuitry (e.g., ADC support components) need adjustment when migrating between versions.
What debug tools are supported for DF36054HV development?
The DF36054HV is fully supported by Renesas' E7 and E8 on-chip emulators, providing real-time trace, hardware breakpoints, and register visibility. These tools require dedicated pins (NMI, P85–P87), which are reserved during emulation-so those pins cannot be used for user I/O in debug mode. The DF36054HV's built-in debug interface eliminates need for external JTAG adapters.
What power supply voltage range does the DF36054HV support?
The DF36054HV operates across a wide supply voltage range of 3.0 V to 5.5 V, making it compatible with both 3.3 V and 5 V system domains. This flexibility simplifies integration into mixed-voltage industrial designs and eliminates level-shifting requirements for many peripheral interfaces, provided I/O voltage levels remain within specification limits.
