Product details
Overview
DF36064GFPV from Renesas Electronics is a 16-bit single-chip microcomputer in the H8/300H Tiny Series, featuring an H8/300H CPU core with H8/300 instruction set compatibility, 64 KB on-chip ROM, 4 KB RAM, and integrated peripherals including UART (SCI), timer modules, and I/O ports. It operates at up to 20 MHz and targets embedded control in industrial equipment and consumer appliances.
For engineers reviewing the DF36064GFPV datasheet, DF36064GFPV pinout, DF36064GFPV application, or DF36064GFPV equivalent, key selection criteria include its 100-pin PQFP package, 3.3 V/5 V dual-voltage operation support, on-chip flash programming capability, and integrated power-down modes for low-power system design.
Technical Context
The DF36064GFPV implements the H8/300H CPU architecture with 24-bit addressing, supporting both big-endian and little-endian data access via software configuration. Its memory map includes dedicated areas for on-chip ROM (H'00000–H'0FFFF), RAM (H'10000–H'10FFF), and peripheral registers (H'F0000–H'F7FFF).
Peripheral integration includes three serial communication interfaces (SCI0–SCI2), a 16-bit timer pulse unit (TPU) with input capture/output compare, a watchdog timer (WDT), and a clock pulse generator supporting crystal, ceramic resonator, or external clock inputs - all configurable via SYSCR1/SYSCR2 and module standby control registers.

Pinout & Package
DF36064GFPV is housed in a 100-pin Plastic Quad Flat Package (PQFP) with 0.65 mm lead pitch, compliant with JEDEC MS-026. The package supports surface-mount assembly and provides thermal dissipation suitable for industrial ambient temperatures (–20°C to +75°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VCC2 | Power supply inputs | VCC = main core supply (3.3 V or 5 V); VCC2 = I/O voltage reference - determines logic level thresholds for port pins. |
| RESET | Active-low reset input | Asynchronous reset signal; must be held low ≥1024 cycles after power stabilization to ensure reliable initialization. |
| CLK / EXTAL | External clock input | Accepts crystal/resonator between EXTAL and XTAL pins; internal oscillator circuit supports 1–20 MHz range. |
| P00–P07 | Port 0 bidirectional I/O | 8-bit parallel port with individual direction control; default as inputs with weak pull-ups enabled after reset. |
| SCI0_TXD / SCI0_RXD | Serial interface channel 0 | Full-duplex UART signals on P20/P21; supports asynchronous communication at up to 1 Mbps with programmable baud rate generator. |
| TPU0A / TPU0B | Timer pulse unit outputs | Channel 0 output compare pins (P40/P41); generate PWM, one-shot pulses, or position-synchronized waveforms. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F3666ADFP | Successor in RL78/F13 family; 16-bit core, 64 KB flash, but uses different instruction set and peripheral register mapping. | Targets same industrial control space but requires full firmware rewrite and PCB layout review due to different pinout and voltage requirements (1.8–5.5 V). | Select when migrating to Renesas' newer low-power platform with enhanced ESD immunity and integrated LIN transceiver support. |

FAQ
What is the maximum operating frequency supported by DF36064GFPV?
The DF36064GFPV supports a maximum system clock frequency of 20 MHz. This is achieved using an external crystal or ceramic resonator connected to the EXTAL/XTAL pins, or via an external clock source applied to the EXTAL pin. Internal prescalers allow division of this clock for peripheral modules, and the CPU executes instructions at the full system clock rate in single-cycle mode for most operations. DF36064GFPV maintains timing compliance across its specified industrial temperature range (–20°C to +75°C) at this frequency.
Does DF36064GFPV support in-system programming of its on-chip flash memory?
Yes, DF36064GFPV supports in-system programming (ISP) of its 64 KB on-chip flash ROM via the boot-mode serial interface (SCI). When configured in boot mode using specific pin settings at power-on, DF36064GFPV enters a bootloader state that accepts firmware images over SCI0 at predefined baud rates. This eliminates the need for external programming hardware and enables field firmware updates. DF36064GFPV's FLMCR1 and FENR registers manage erase and program operations during user-mode programming.
What power management features does DF36064GFPV provide for low-power applications?
DF36064GFPV implements three hardware-supported power-down modes: Sleep (CPU halted, peripherals active), Standby (CPU and most peripherals halted, RAM retained), and Subsleep (deep sleep with real-time clock wake-up capability). These modes are controlled via SYSCR1 and SYSCR2 registers, and wake-up can be triggered by external interrupts, timer events, or serial receive activity. DF36064GFPV achieves sub-10 µA standby current in Subsleep mode, making it suitable for battery-powered sensor nodes and energy-conscious industrial controls.
How many serial communication interfaces does DF36064GFPV integrate, and what protocols do they support?
DF36064GFPV integrates three independent Serial Communication Interfaces (SCI0, SCI1, SCI2), each capable of asynchronous full-duplex UART operation. They support standard NRZ format with programmable baud rates, parity, stop bits, and frame length. SCI2 includes hardware flow control and half-duplex RS-485 direction control support. None of the SCIs implement synchronous protocols like SPI or I²C natively; those functions require bit-banging or external peripherals. DF36064GFPV's SCI modules are accessed via dedicated memory-mapped registers in the H'F0000–H'F7FFF peripheral address space.
Is DF36064GFPV pin-compatible with other members of the H8/36064 Group?
DF36064GFPV shares the same 100-pin PQFP package and pin assignment with other variants in the H8/36064 Group, including DF36064GFP and HD64F36064G. Pin functions are identical across these variants; differences lie in mask ROM vs. flash memory content, operating voltage tolerance, and minor electrical characteristics. DF36064GFPV is fully pin-compatible with HD64F36064G, allowing direct substitution in legacy designs documented under the NEC part numbering scheme without PCB modification.
