Product details
Overview
DF36078GFZV from Renesas Electronics is a 16-bit single-chip microcomputer in the H8/36078 Group, featuring the H8/300H CPU core with instruction compatibility to the H8/300, 128 KB on-chip ROM, 8 KB RAM, and integrated peripherals including 3-channel SCI, 16-bit timer/counters, and 8-channel 10-bit ADC - deployed in industrial control panels requiring deterministic real-time response.
For engineers reviewing the DF36078GFZV datasheet, DF36078GFZV pinout, DF36078GFZV application, or DF36078GFZV equivalent, key selection criteria include its 5V operation, 20 MHz max CPU clock, 64-pin LQFP package, and support for on-board programming via SCI channel 1 in boot mode.
Technical Context
The DF36078GFZV implements the H8/300H CPU architecture with 24-bit address space, supporting both big-endian and little-endian data access modes. It integrates a programmable clock pulse generator with internal RC oscillator (±1% trimmable), external crystal/ceramic resonator support, and selectable system clocks (main, sub, PLL-derived).
Peripheral subsystems include three serial communication interfaces (SCI0–SCI2) with asynchronous/full-duplex capability, four 16-bit timer/counters with input capture/output compare, and an 8-channel 10-bit successive-approximation ADC with conversion time of 10.5 µs per channel at 5 V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | H8/300H 16-bit RISC core, instruction-compatible with H8/300, enabling legacy code reuse without recompilation. |
| Memory | 128 KB on-chip ROM (mask-programmed), 8 KB on-chip RAM - eliminates need for external memory in compact embedded designs. |
| Max Clock Frequency | 20 MHz CPU clock (50 ns instruction cycle) - supports real-time control loops with ≤50 µs task resolution. |
| Supply Voltage | 4.5 V to 5.5 V operation - compatible with standard industrial 5 V rail, no level-shifting required for legacy peripherals. |
| ADC Resolution & Speed | 10-bit SAR ADC, 8 channels, 10.5 µs conversion time - sufficient for motor current sensing and analog sensor interfacing. |
| Package | 64-pin LQFP (10 mm × 10 mm, 0.5 mm pitch) - enables high I/O density while supporting automated SMT assembly. |
| Operating Temperature | −20 °C to +75 °C ambient - rated for commercial/industrial indoor equipment environments. |
Pinout & Package
DF36078GFZV is housed in a 64-pin LQFP package (JEDEC MS-026AC) with exposed thermal pad. Pin functions are defined per Hardware Manual Rev.3.00, Section 1.3–1.4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC, VSS | Power supply and ground | Dedicated power/ground pairs per quadrant minimize noise coupling and ensure stable core/peripheral operation. |
| RESET | Active-low reset input | Asynchronous reset with internal pull-up; requires external capacitor for glitch filtering in noisy environments. |
| CLK, EXTAL, XTAL | System clock inputs | Supports crystal (1–8 MHz), ceramic resonator, or external clock source - enables flexible timing architecture. |
| P00–P07 | Port 0 bidirectional I/O | Configurable as general-purpose I/O or alternate functions (e.g., SCI0 TX/RX, timer outputs); 5 V-tolerant inputs. |
| AD0–AD7 | ADC input channels | Eight dedicated analog inputs mapped to P10–P17; share pins with port functionality - requires careful mode configuration. |
Key Features
| Feature | Design Value |
|---|---|
| On-board programming support | SCI channel 1 (P21/P22) enables firmware updates in-system without JTAG emulator - reduces field service cost. |
| Low-voltage detection circuit | Integrated reset-on-drop feature triggers at 4.2 V (typ.) - prevents erratic operation during brown-out conditions. |
| Interrupt flexibility | 29 interrupt sources with priority encoding and edge-selectable external interrupts (IEGR1/IEGR2 registers) - simplifies event-driven firmware design. |
| Timer resource integration | Four 16-bit timers with input capture, output compare, and PWM generation - supports motor phase control and pulse-width measurement. |
| EMI-reduced pin treatment | NC pins explicitly designated and prohibited from connection - avoids unintended coupling paths affecting EMC compliance. |
Applications
| Industrial PLC I/O Module | Motor Drive Control Board |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F36078G | Same die, identical electrical specs and pinout; differs only in marking and packaging (tray vs. tube). | No functional difference; used interchangeably in production where Renesas part numbering conventions apply. | Select HD64F36078G when sourcing from legacy inventory or distributor stock with older Renesas branding. |
| H8/36077GF | 64 KB ROM, 4 KB RAM, same peripheral set and pinout - reduced memory capacity only. | Suitable for simpler control tasks with smaller firmware footprint; not recommended for applications requiring >64 KB code space. | Choose H8/36077GF where cost sensitivity outweighs memory headroom, and firmware size remains under 56 KB. |
Compared with DF36078GFZV, HD64F36078G offers identical functionality with legacy nomenclature, while H8/36077GF provides a lower-memory variant for cost-constrained designs - both require no PCB changes but differ in flash capacity and qualification documentation traceability.

FAQ
What is the maximum operating frequency of the DF36078GFZV?
The DF36078GFZV supports a maximum CPU clock frequency of 20 MHz, corresponding to a 50 ns instruction cycle time. This rating assumes operation within the specified 4.5 V to 5.5 V supply range and −20 °C to +75 °C ambient temperature. The actual achievable frequency depends on clock source stability and PCB layout integrity, particularly for external crystal connections.
Does the DF36078GFZV support in-system programming?
Yes, the DF36078GFZV supports in-system programming via SCI channel 1 (pins P21/RXD and P22/TXD) in boot mode. This capability allows firmware updates without removing the device from the board. The process requires setting the appropriate boot mode pins at power-on and using Renesas' F-ZTAT™ protocol - documented in Application Note REJ05B0520.
What is the function of the NC pins on the DF36078GFZV?
The NC (not connected) pins on the DF36078GFZV are internally unconnected or reserved for factory testing and must remain unconnected in the final design. Connecting external circuitry to NC pins may cause unpredictable behavior or violate the device's EMI specifications. This requirement is explicitly stated in the Hardware Manual's General Precautions section.
How much on-chip memory does the DF36078GFZV include?
The DF36078GFZV integrates 128 KB of mask-programmed ROM and 8 KB of SRAM. The ROM is used for program storage and cannot be rewritten in-circuit; the RAM serves as data memory and stack space. Both memory blocks are accessed directly by the H8/300H CPU without wait states under normal operating conditions.
Is the DF36078GFZV pin-compatible with other H8/3607x series devices?
Yes, the DF36078GFZV shares the same 64-pin LQFP package and pin assignment with the H8/36077 and H8/36079 groups. However, differences exist in memory size, peripheral enablement, and some register configurations - meaning hardware layout is interchangeable, but firmware must be validated per specific group features and memory map.
