Product details
Overview
DF36079GFZV from Renesas Electronics is a 16-bit single-chip microcomputer in the H8/36079 Group, featuring the H8/300H CPU core, 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. It operates at up to 20 MHz with 3.3 V or 5 V supply and targets embedded control in industrial equipment and office automation.
For engineers reviewing the DF36079GFZV datasheet, DF36079GFZV pinout, DF36079GFZV application, or DF36079GFZV equivalent, key selection criteria include its H8/300H instruction compatibility, on-chip clock generator with trimming capability, low-voltage detection circuit, and support for on-board programming via SCI channel 1 in boot mode.
Technical Context
The DF36079GFZV implements the H8/300H CPU architecture with 24-bit address space, supporting both 8- and 16-bit data operations. Its system clock is generated by an on-chip RC oscillator (trimmable ±1.5% over temperature) or external crystal/ceramic resonator up to 20 MHz.
Peripheral integration includes three serial communication interfaces (SCI), four 16-bit timer modules (with input capture/output compare), and an 8-channel 10-bit successive-approximation ADC with sample-and-hold. All peripherals are memory-mapped and controlled via dedicated registers accessible in supervisor or user mode.
Key Specifications

| P20–P27 | Port 2 bidirectional I/O | Includes P21/RXD and P22/TXD for SCI channel 1 - used for on-board programming in boot mode |
| NMI | Non-maskable interrupt | Reserved for E7/E8 emulator use; not available in debug configurations |
Key Features
| Feature | Design Value |
|---|---|
| On-chip RC oscillator with trimming | Factory-trimmed ±1.5% accuracy over –20°C to +75°C; user-adjustable via RCTRMDR register |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F36079G | Same die, identical electrical specs and pinout; differs only in marking and packaging documentation | No functional difference - used interchangeably in production where Renesas part numbering conventions apply | Select HD64F36079G when sourcing from legacy Renesas distribution channels or referencing older design documentation |

FAQ
What is the maximum operating frequency of the DF36079GFZV?
The DF36079GFZV supports a maximum system clock frequency of 20 MHz. This applies whether using the internal RC oscillator (after trimming) or an external crystal/ceramic resonator. At 20 MHz, the CPU achieves 20 million instructions per second with single-cycle execution for most basic operations, enabling tight real-time control loops in applications like motor drive and sensor acquisition.
Does DF36079GFZV support in-system programming?
Yes, DF36079GFZV supports on-board programming via SCI channel 1 (P21/RXD and P22/TXD) when configured in boot mode. This allows firmware updates without external programmers - ideal for field maintenance. The process requires a UART host sending a specific command sequence; no external ROM or bootloader code is needed as the functionality is hardwired into the chip's reset vector logic.
What are the power supply requirements for DF36079GFZV?
DF36079GFZV operates from either a 3.3 V ±10% or 5 V ±10% supply, with separate VCC and VSS pins per functional block. The device includes an on-chip low-voltage detection (LVD) circuit with programmable thresholds (e.g., 4.3 V, 3.8 V, 3.3 V) to generate a reset before supply collapse corrupts internal state - critical for reliable operation in battery-powered or unregulated line-powered systems.
How many ADC channels does DF36079GFZV have, and what is their resolution?
DF36079GFZV integrates an 8-channel, 10-bit successive-approximation ADC with sample-and-hold. Each channel maps to dedicated port pins (e.g., AN0–AN7), and conversion time is 12.5 µs per sample at 20 MHz. The ADC supports software or timer-triggered conversions and includes built-in offset calibration - making it suitable for precision analog sensing in industrial and appliance applications.
Is DF36079GFZV pin-compatible with other H8/36079 Group members?
Yes, DF36079GFZV shares the same 100-pin LQFP package and pinout with all members of the H8/36079 Group, including HD64F36079G and H8/36079LF. Differences between variants are limited to memory size (ROM/RAM), operating voltage range, and temperature grade - not pin assignment or peripheral mapping. This enables hardware reuse across product tiers during design and qualification.
