Product details
Overview
DF36054GHV 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 units, and 80-pin LQFP package. It operates at up to 20 MHz, supports single-supply 5 V operation, and targets embedded control applications requiring deterministic real-time response and on-chip nonvolatile program storage.
For engineers reviewing the DF36054GHV datasheet, DF36054GHV pinout, DF36054GHV application, or DF36054GHV equivalent, this page provides verified technical context, validated pin functions, confirmed electrical specifications, real-world use cases in industrial control and instrumentation, and two documented alternative microcontrollers with explicit functional and packaging differences.
Technical Context
The DF36054GHV implements the H8/300H CPU architecture with full instruction set compatibility to the 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 clock division, and four power-down modes (Sleep, Standby, Subsleep, Subactive) controlled via SYSCR1/SYSCR2 registers.
On-chip memory includes 128 KB of ROM (flash-programmable), 8 KB of RAM, and dedicated registers for flash control (FLMCR1/FLMCR2), erase block management (EBR1), and power gating (FLPWCR). Peripheral modules include three serial communication interfaces (SCI), one I2C bus interface, eight 16-bit timers (including PWM-capable TPU), and 64 general-purpose I/O pins mapped across ports P0–P9.

FAQ
What is the maximum operating frequency of the DF36054GHV?
The DF36054GHV operates at a maximum frequency of 20 MHz when powered by a 5 V supply and using an external crystal or clock source. This frequency is specified under conditions of VCC = 4.5–5.5 V and ambient temperature TA = –20°C to +75°C, and enables instruction execution at 50 ns per cycle. The DF36054GHV's system clock generator supports direct crystal connection (1–20 MHz), ceramic resonator, or external clock input, with internal prescaling for peripheral clocks.
Does the DF36054GHV support in-system programming of its flash memory?
Yes, the DF36054GHV supports in-system programming (ISP) of its 128 KB on-chip flash ROM via its built-in boot ROM and SCI interface. Firmware updates can be performed without removing the DF36054GHV from the target board, using standard UART communication and Renesas-provided programming utilities. Flash write/erase operations are controlled through dedicated registers (FLMCR1, FLMCR2, EBR1) and require specific timing and voltage conditions as defined in the Hardware Manual Rev.4.00.
What power-saving modes are available on the DF36054GHV?
The DF36054GHV provides four hardware-controlled power-down modes: Sleep (CPU halted, peripherals active), Standby (CPU and most peripherals halted, RAM retained, ~10 µA typical), Subsleep (selected modules active, ultra-low wake-up latency), and Subactive (reduced clock frequency for background tasks). These modes are configured via SYSCR1 and SYSCR2 registers and enable flexible energy management in battery-powered or thermally constrained applications using the DF36054GHV.
Is the DF36054GHV pin-compatible with other H8/36054 Group members?
Yes, the DF36054GHV shares identical pin assignment and electrical characteristics with all members of the H8/36054 Group, including HD64F36054 and HD64F36054G. All variants use the same 80-pin LQFP package and maintain full pin-to-pin compatibility - allowing direct substitution within the same group without PCB layout changes, provided voltage, timing, and firmware requirements align.
What debug tools are supported for the DF36054GHV?
The DF36054GHV is fully supported by Renesas' E7 and E8 on-chip emulators, enabling real-time debugging, breakpoint setting, register inspection, and memory read/write during development. Debug access uses dedicated pins (NMI, P85–P87), and the DF36054GHV's hardware debug interface complies with Renesas' standard protocol. Development environments such as High-Performance Embedded Workshop 3 and C/C++ toolchains (REJ10B0058) provide full integration for the DF36054GHV.
