Renesas DF36077GFZV

Overview

DF36077GFZV from Renesas Electronics is a 16-bit single-chip microcomputer in the H8/36077 Group, featuring the H8/300H CPU core with instruction set compatibility to H8/300. It integrates on-chip ROM (128 KB), RAM (8 KB), and peripherals including 3-channel SCI, 16-bit timer/counters, and 8-channel 10-bit ADC - designed for embedded control in industrial equipment and office automation systems.

For engineers reviewing the DF36077GFZV datasheet, DF36077GFZV pinout, DF36077GFZV application, or DF36077GFZV equivalent, key selection criteria include its 16-bit H8/300H architecture, 128 KB on-chip ROM with ROM-less boot capability, 10-bit ADC resolution, and support for external crystal up to 20 MHz - all critical for deterministic real-time control in cost-sensitive, space-constrained designs.

Technical Context

The DF36077GFZV implements the H8/300H CPU core with 24-bit address space, supporting both ROM-based and ROM-less boot modes via SCI channel 1. Its clock system includes an on-chip RC oscillator (trimmable ±1% at 16 MHz) and external crystal/ceramic resonator support (1–20 MHz), with programmable PLL for internal clock multiplication.

Peripheral integration includes three serial communication interfaces (SCI0–SCI2), two 16-bit timer modules (each with input capture/output compare), and an 8-channel 10-bit successive-approximation ADC with sample-and-hold - all mapped to dedicated I/O ports with configurable pull-up/pull-down and drive strength.

Key Specifications

Pinout & Package

DF36077GFZV is housed in a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with 79 user I/O pins, 4 power/ground pairs, and dedicated reset, clock, and debug pins. NC pins are internally unconnected and must remain floating.

FAQ

What is the maximum operating frequency of the DF36077GFZV?

The DF36077GFZV supports a maximum external clock frequency of 20 MHz when using a crystal or ceramic resonator. Its on-chip RC oscillator operates at 16 MHz with ±1% accuracy after trimming. Internal bus timing is synchronized to this clock source, enabling instruction execution at up to 20 MIPS under optimal conditions. The DF36077GFZV datasheet specifies timing parameters for all peripheral modules at this maximum frequency.

Does the DF36077GFZV include on-chip flash or ROM memory?

The DF36077GFZV contains 128 KB of mask-programmed on-chip ROM and 8 KB of SRAM. It does not include flash memory. The ROM is programmed during wafer fabrication and cannot be rewritten in-system. This architecture ensures deterministic boot timing and immunity to write corruption - a key requirement for safety-critical industrial controllers. DF36077GFZV supports ROM-less boot via SCI1 for development and field updates.

Can the DF36077GFZV operate from a 3.3 V supply?

Yes, the DF36077GFZV operates over a supply voltage range of 3.0 V to 5.5 V, making it compatible with both 3.3 V and 5 V system environments. At 3.3 V, the maximum guaranteed operating frequency is reduced to 12 MHz per the electrical characteristics table. All I/O pins are 5 V tolerant when configured as inputs, allowing direct interface with higher-voltage peripherals without level shifters. DF36077GFZV maintains full peripheral functionality across this voltage range.

How many ADC channels does the DF36077GFZV support, and what is their resolution?

The DF36077GFZV integrates an 8-channel, 10-bit successive-approximation ADC with sample-and-hold circuitry. Each channel can be individually triggered by software, timer overflow, or external event. Conversion time is 1.25 µs per sample at maximum clock rate. The ADC uses AVCC and AVSS as reference inputs and supports single-ended input configuration only. DF36077GFZV's ADC is mapped to Port 6 pins (P60–P67) and shares resources with general-purpose I/O functionality.

Is the DF36077GFZV pin-compatible with other members of the H8/36077 Group?

Yes, the DF36077GFZV is pin-compatible with other variants in the H8/36077 Group, including the HD64F36077G (DIP-64) and H8/36077LF (low-power version). All share identical 100-pin LQFP pinout, memory map, and peripheral register layout. Differences are limited to internal configuration (e.g., clock source options, power modes) and marking - not pin function or electrical behavior. DF36077GFZV firmware and PCB layout are directly reusable across these variants.
