Product details
Overview
DF36034GFZV from Renesas Electronics is a 16-bit single-chip microcontroller in the H8/36034 Group, featuring the H8/300H CPU core, 128 KB on-chip ROM, 8 KB RAM, and integrated peripherals including SCI, I2C, timers, and 8-channel 10-bit ADC - deployed in industrial control panels requiring deterministic real-time response and low-power operation.
For engineers reviewing the DF36034GFZV datasheet, DF36034GFZV pinout, DF36034GFZV application, or DF36034GFZV equivalent, key selection criteria include its 16-MHz max operating frequency, 5V supply tolerance, 80-pin PQFP package with dedicated reset and NMI inputs, and support for on-chip debugging via E7/E8 emulator interface.
Technical Context
The DF36034GFZV implements the H8/300H CPU architecture with instruction set compatibility to the legacy 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.
Peripheral modules include three serial communication interfaces (SCI), one I2C bus interface, eight 16-bit timer channels (with input capture/output compare), and an 8-channel 10-bit successive-approximation ADC with internal reference voltage. All modules are memory-mapped and accessible via fixed register addresses defined in the hardware manual.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F36034G | Same die, identical electrical specs and pinout; differs only in marking and packaging (tray vs. tube) | No functional difference; qualified for same industrial temperature range (−20°C to +75°C) | Select HD64F36034G for standard tray delivery where DF36034GFZV tube packaging is unavailable |
| R5F36603GFP | Successor in RL78/G13 family: lower power (1.8–5.5 V), smaller footprint (64-pin LQFP), but reduced peripheral count (no I²C, only 2× SCI) | Better suited for ultra-low-power sensor nodes; lacks ADC channel count and ROM size for complex control tasks | Choose R5F36603GFP only when migrating to newer platform with revised layout and firmware rewrite |
Compared with DF36034GFZV, HD64F36034G offers identical functionality in alternate packaging, while R5F36603GFP trades peripheral richness and memory for modern low-power architecture - making DF36034GFZV optimal for legacy-compatible, feature-rich industrial control where 5V robustness and full peripheral integration are required.

FAQ
What is the maximum operating frequency of the DF36034GFZV?
The DF36034GFZV operates at a maximum frequency of 16 MHz when supplied with a 5 V ±10% supply and using an external crystal oscillator. This frequency governs instruction throughput, interrupt response time, and peripheral clock rates - all specified under DC and AC characteristics in the hardware manual. The DF36034GFZV achieves deterministic timing critical for closed-loop control in industrial applications.
Does the DF36034GFZV support in-circuit debugging?
Yes, the DF36034GFZV supports on-chip debugging via Renesas E7 and E8 emulators using dedicated pins P85, P86, and P87. When enabled, these pins are reserved for emulator communication and cannot be used for general-purpose I/O. The DF36034GFZV also reserves the NMI pin exclusively for emulator use during debugging sessions.
What are the power management capabilities of the DF36034GFZV?
The DF36034GFZV implements four distinct low-power modes: Sleep, Standby, Subsleep, and Subactive - each controlled by SYSCR1 and SYSCR2 registers. In Subsleep mode, current consumption drops below 100 µA while retaining RAM contents and enabling wake-up via external interrupt or timer. These modes make the DF36034GFZV suitable for battery-powered industrial sensors where runtime extension is critical.
Is the DF36034GFZV pin-compatible with other H8/360xx series MCUs?
The DF36034GFZV shares the same 80-pin PQFP package and core pin assignment (power, reset, clock, NMI, SCI, ADC, etc.) with other members of the H8/3603x Group, including HD64F36034G and HD64F36037G. However, peripheral enablement and register mapping differ across variants - firmware must be validated per specific part number. The DF36034GFZV is not pin-compatible with H8/3605x or H8/36036 devices due to differing peripheral configurations.
What development tools are officially supported for the DF36034GFZV?
Renesas officially supports the E7 and E8 on-chip emulators for debugging the DF36034GFZV, along with the High-Performance Embedded Workshop 3 IDE, C/C++ Compiler REJ10B0058, and Simulator/Debugger REJ10B0211. Application notes such as REJ05B0520 cover single-power-supply on-board programming using SCI3 (P21/P22). No third-party JTAG adapters are certified for DF36034GFZV.
