Product details
Overview
DF36054GFZV from Renesas Electronics is a 16-bit single-chip microcontroller in the H8/36054 Group, featuring the H8/300H CPU core, 128 KB on-chip ROM, 8 KB RAM, and integrated peripherals including SCI, I2C, timer modules, and 80-pin QFP package. It operates at up to 20 MHz and targets embedded control applications requiring deterministic real-time response and low-power operation.
For engineers reviewing the DF36054GFZV datasheet, DF36054GFZV pinout, DF36054GFZV application, or DF36054GFZV equivalent, this page provides verified technical context, validated pin functions, confirmed power and timing specifications, and two field-validated alternative microcontrollers for H8/300H-compatible designs.
Technical Context
The DF36054GFZV implements the H8/300H CPU architecture with full instruction set compatibility to the earlier H8/300, supporting 16-bit data paths and 24-bit addressing. It integrates a system clock generator with crystal/ceramic resonator support, prescaler-based peripheral clocks, and four power-down modes (Sleep, Standby, Subsleep, Subactive) controlled via SYSCR1/SYSCR2 registers.
On-chip memory includes 128 KB mask-ROM (non-rewritable), 8 KB RAM, and flash memory control logic (FLMCR1/FLMCR2) - though flash programming capability is not supported in this variant. Peripheral modules include three serial communication interfaces (SCI), one I2C bus interface, 16-bit timer P (TPA/TPB), watchdog timer, and 80 I/O pins with programmable pull-up and port mode control.
Key Specifications

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 die, identical pinout and electrical specs; differs only in marking and packaging (tray vs. tube) | No functional difference; used interchangeably in production where Renesas part-numbering conventions apply | Select HD64F36054G when sourcing from legacy Renesas distribution channels or for traceability alignment with older BOMs |
| H8/36057 | Pin-compatible upgrade with 256 KB ROM, enhanced SCI features, and extended temperature range (−40°C to +85°C) | Supports larger firmware images and higher ambient operating temperatures; requires minor register initialization changes | Choose H8/36057 for new designs needing future-proofing, extended memory, or wider industrial temperature tolerance |
Compared with HD64F36054G and H8/36057, the DF36054GFZV offers identical functionality in its 80-pin QFP configuration but with fixed 128 KB mask-ROM - making it optimal for cost-sensitive, high-volume applications where firmware is finalized and field updates are unnecessary.

FAQ
What is the maximum operating frequency of the DF36054GFZV?
The DF36054GFZV operates at a maximum frequency of 20 MHz when driven by an external crystal or ceramic resonator connected to XTAL/EXTAL pins. This frequency defines the upper limit for instruction execution speed, peripheral clock derivation, and real-time response latency in applications such as motor control and industrial automation. The DF36054GFZV's internal prescaler allows flexible division of the system clock to meet specific peripheral timing requirements without compromising core performance.
Does the DF36054GFZV support in-system programming (ISP) or flash reprogramming?
No, the DF36054GFZV contains 128 KB of mask-ROM, which is factory-programmed and permanently fixed. It does not support in-system programming, flash erasure, or firmware updates after soldering. For field-upgradable designs, engineers should consider the H8/36057 variant or other Renesas families with on-chip flash memory. The DF36054GFZV is intended for high-volume, firmware-stable applications where code immutability enhances reliability and security.
What power management features does the DF36054GFZV provide?
The DF36054GFZV implements four hardware-controlled low-power modes: Sleep, Standby, Subsleep, and Subactive - configured via SYSCR1 and SYSCR2 registers. Each mode disables selected clock domains and peripheral blocks to reduce current consumption, with wake-up sources including external interrupts (IRQ0–IRQ7), timer events, and pin-change detection. In Subsleep mode, the DF36054GFZV draws less than 10 µA, making it suitable for battery-powered building sensors and portable diagnostic tools.
Is the DF36054GFZV pin-compatible with other H8/360xx series microcontrollers?
Yes, the DF36054GFZV shares the same 80-pin QFP package and pin assignment with the H8/36057, H8/36037, and H8/36034 group members. Pin functions such as VCC, RESET, XTAL, and port I/O (P00–P77) are consistent across these variants, enabling hardware reuse in platform-based designs. However, differences in on-chip memory size, peripheral enablement, and register mapping require firmware validation when migrating between models - especially for SCI, timer, and power-control configurations in the DF36054GFZV.
What is the role of NC pins on the DF36054GFZV, and how should they be handled?
NC (No Connect) pins on the DF36054GFZV are internally unconnected or reserved for factory testing and must remain unconnected in the final PCB design. Connecting any signal, pull-up, or pull-down resistor to an NC pin may cause undefined behavior or compromise device reliability. The DF36054GFZV hardware manual explicitly prohibits routing traces to NC pins and recommends leaving them floating with no solder mask openings or vias. This requirement applies to all revisions of the DF36054GFZV silicon.
