Renesas DF36014GFYV

Overview

DF36014GFYV from Renesas Electronics is a 16-bit single-chip microcomputer in the H8/36014 Group, featuring the H8/300H CPU core with instruction set compatibility to H8/300, 128 KB on-chip ROM, 8 KB RAM, and integrated peripherals including SCI, I²C, timer modules, and 8-channel 10-bit ADC - deployed in industrial control panels requiring deterministic real-time response and firmware-upgradable logic.

For engineers reviewing the DF36014GFYV datasheet, DF36014GFYV pinout, DF36014GFYV application, or DF36014GFYV equivalent, key selection criteria include its 16-MHz max operating frequency, 5 V supply tolerance, 80-pin PQFP package, and support for on-board programming via boot mode using SCI3 channel 1 - critical for field-deployable embedded systems with lifecycle maintenance requirements.

Technical Context

The DF36014GFYV implements the H8/300H CPU architecture with 24-bit address space, supporting both little-endian memory layout and 16-bit data paths. It integrates a system clock generator with crystal/ceramic resonator support (1–10 MHz), prescaler S for peripheral clock division, and three power-down modes: Sleep, Standby, and Subsleep - enabling dynamic power management in battery-backed instrumentation.

Peripheral integration includes two serial communication interfaces (SCI1 and SCI3), one I²C bus interface, four 16-bit timer modules (with input capture/output compare), and an 8-channel 10-bit successive-approximation ADC with internal reference voltage - all mapped to dedicated I/O pins with configurable port modes and interrupt edge select capability.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the DF36014GFYV?

The DF36014GFYV operates at a maximum frequency of 16 MHz when supplied with 5 V. This frequency is achieved using the internal system clock generator with an external 1–10 MHz crystal or ceramic resonator, and it defines the upper bound for instruction throughput and real-time interrupt response time. The DF36014GFYV maintains full functionality across its specified industrial temperature range (−40°C to +85°C) at this speed.

Does the DF36014GFYV support in-system programming without a JTAG debugger?

Yes, the DF36014GFYV supports in-system programming via SCI3 (P21/RXD and P22/TXD) using boot mode, eliminating the need for a JTAG debugger. Entry into boot mode requires specific reset timing and pin states, after which firmware can be uploaded over UART using Renesas' standard programming protocol. This capability is fully implemented in the DF36014GFYV and documented in the Hardware Manual Rev.4.00.

What power management modes does the DF36014GFYV provide?

The DF36014GFYV provides three hardware-supported power-down modes: Sleep, Standby, and Subsleep. Each mode disables different clock domains and peripheral blocks to reduce current draw, with wakeup possible via external interrupt, timer match, or RTC alarm. Subsleep mode draws less than 10 µA while retaining RAM content and RTC operation - a key feature for battery-operated DF36014GFYV deployments.

Is the DF36014GFYV pin-compatible with other members of the H8/36014 Group?

Yes, the DF36014GFYV shares the same 80-pin PQFP package and pinout with other members of the H8/36014 Group, including HD64F36014G and HD64336014G. All variants use identical pin assignments for power, reset, clock, I/O, and peripheral signals - enabling drop-in replacement within the same group when memory or feature variants differ.

What is the ADC resolution and channel count on the DF36014GFYV?

The DF36014GFYV integrates an 8-channel, 10-bit successive-approximation ADC with internal reference voltage generation. It supports single-ended input configuration across AD0–AD7 pins and includes sample-and-hold circuitry for accurate conversion timing. This ADC is fully functional in the DF36014GFYV and does not require external reference components for basic operation.
