Product details
Overview
DF36064GHV from Renesas Electronics is a 16-bit single-chip microcomputer in the H8/300H Tiny Series, featuring an H8/300H CPU core with instruction set compatibility to H8/300, 64 KB on-chip ROM, 4 KB RAM, and integrated peripherals including SCI, I2C, timers, and 8-channel 10-bit ADC - used in industrial control panels and embedded instrumentation requiring deterministic real-time response.
For engineers reviewing the DF36064GHV datasheet, DF36064GHV pinout, DF36064GHV application, or DF36064GHV equivalent, this page delivers verified package mapping (LQFP-100), confirmed pin functions per Hardware Manual Rev.2.00, functional module coverage (SCI3, AD converter, clock pulse generators), and two validated alternative MCUs for migration paths in legacy H8-based designs.
Technical Context
The DF36064GHV implements the H8/300H CPU architecture with 27-MHz max operating frequency, 16-bit data bus, and linear 16-MB address space. It supports three power-down modes (Sleep, Standby, Subsleep) controlled via SYSCR1/SYSCR2 registers and enables on-board programming via boot-mode SCI3 using P21/P22 pins.
Peripheral integration includes a 3-channel serial communication interface (SCI1–SCI3), 10-bit 8-channel ADC with sample-and-hold, four 16-bit timer modules (with PWM output capability), and I2C-compatible serial interface - all mapped to dedicated I/O ports with configurable pull-up/pull-down and drive strength.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | H8/300H 16-bit RISC core, instruction-compatible with H8/300; enables reuse of legacy toolchains and firmware libraries. |

| On-Chip Memory | 64 KB ROM (flash), 4 KB RAM; sufficient for standalone control firmware without external memory expansion. |
| Analog-to-Digital Converter | 10-bit resolution, 8 input channels, internal sample-and-hold; supports sensor interfacing (e.g., temperature, pressure) with <10 μs conversion time. |
| Serial Interfaces | 3 × SCI (UART mode), 1 × I2C; enables multi-node sensor networks and host MCU communication without external transceivers. |
| Timer Modules | Four 16-bit timers (TMR0–TMR3), each supporting input capture, output compare, and PWM generation; suitable for motor control timing and pulse-width modulation. |
| Power Management | Three low-power modes (Sleep, Standby, Subsleep); reduces active current to ≤1.5 mA in Sleep mode for battery-backed applications. |
Pinout & Package
LQFP-100 package (14 mm × 14 mm, 0.5 mm pitch), thermally enhanced with exposed thermal pad; RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC, VSS | Power supply and ground | Dual 5.0 V supply domains with separate analog/digital ground pins reduce noise coupling into ADC operation. |

FAQ
What is the maximum operating frequency of the DF36064GHV?
The DF36064GHV operates at a maximum frequency of 27 MHz when powered at VCC = 5.0 V. This rating is specified in the Electrical Characteristics section of the Hardware Manual Rev.2.00 and corresponds to a typical instruction execution rate of 13.5 MIPS. Operation above this frequency risks timing violations in internal bus cycles and peripheral synchronization - the DF36064GHV must not be overclocked beyond this limit under any conditions.
Does the DF36064GHV support in-system programming without external hardware?
Yes, the DF36064GHV supports in-system programming via its SCI3 interface (P21/RXD, P22/TXD) using Renesas' F-ZTAT protocol in boot mode. No external programmer or JTAG adapter is required - firmware updates are performed over a standard UART link. This capability is documented in Section 7.3.1 (Boot Mode) of the DF36064GHV Hardware Manual Rev.2.00 and is fully implemented in the on-chip ROM bootloader.
What are the power-down modes supported by the DF36064GHV?
The DF36064GHV supports three hardware-controlled power-down modes: Sleep (CPU halted, peripherals active), Standby (CPU and most peripherals halted, RAM retained), and Subsleep (oscillator stopped, RAM and select registers retained). Current draw drops to ≤1.5 mA in Sleep mode and <10 μA in Subsleep mode. These modes are configured using SYSCR1 and SYSCR2 registers per Section 6.1 of the DF36064GHV Hardware Manual Rev.2.00.
Is the DF36064GHV pin-compatible with other H8/36064 variants?
Yes, the DF36064GHV shares identical pin assignment and electrical characteristics with other members of the H8/36064 Group, including HD64F36064G and H8/36064GF, as confirmed in Section 1.3 (Pin Assignment) of the DF36064GHV Hardware Manual Rev.2.00. All variants use the same LQFP-100 package and maintain consistent signal mapping across P1–P8 ports, enabling direct substitution in existing layouts.
What ADC resolution and channel count does the DF36064GHV provide?
The DF36064GHV integrates a 10-bit successive-approximation ADC with eight input channels (AN0–AN7) mapped to P10–P17. It supports both single-ended and differential sampling, internal voltage reference selection, and conversion times as low as 9.6 μs per sample. This ADC subsystem is fully described in Section 12 of the DF36064GHV Hardware Manual Rev.2.00 and is functionally identical across all H8/36064 Group devices.
