Product details
Overview
DF3064BF25V from Renesas Electronics is a 16-bit single-chip microcomputer in the H8/3062 Group, featuring an H8/300H CPU core with 32-bit internal architecture, 256 KB on-chip flash memory (F-ZTAT™), 8 KB RAM, and integrated peripherals including A/D and D/A converters, timers, SCI, and watchdog timer. It operates at up to 25 MHz and targets embedded control systems requiring high integration and flexible firmware updates.
For engineers reviewing the DF3064BF25V datasheet, DF3064BF25V pinout, DF3064BF25V application, or DF3064BF25V equivalent, this page delivers verified technical context, package mapping, functional role in real-time control systems, and validated alternative options for migration or second sourcing.
Technical Context
The DF3064BF25V implements the H8/300H CPU instruction set with 32-bit internal data paths and supports multiple operating modes (single-chip, expanded bus) via MDCR/SYSCR registers. Its on-chip flash memory enables in-system programming and supports address output functions with selectable update modes (Mode 1 or Mode 2).
Peripheral integration includes a 10-bit A/D converter with 8 channels, 8-bit D/A converter, four 16-bit timers (two with capture/compare), two 8-bit timers, programmable timing pattern controller (TPC), and serial communication interface (SCI) compatible with UART protocols - all clocked from a single external crystal or ceramic resonator with VCL pin-based voltage-controlled oscillator support.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | H8/300H 16-bit core with 32-bit internal architecture; executes instructions at up to 25 MHz system clock. |
| Flash Memory | 256 KB on-chip F-ZTAT™ flash; supports single-power-supply reprogramming and in-system updates without external UV erasure. |
| RAM Size | 8 KB on-chip RAM; sufficient for real-time task stacks, interrupt handlers, and small data buffers in control applications. |
| A/D Converter | 10-bit resolution, 8-channel SAR ADC; enables precise analog sensor interfacing (e.g., temperature, pressure, motor current) with hardware-triggered sampling. |
| D/A Converter | 8-bit resolution, single-channel DAC; provides analog output for actuator control, calibration signals, or reference generation. |
| Timers | Four 16-bit timers (two with input capture/output compare), two 8-bit timers, and TPC; supports PWM generation, pulse measurement, and complex timing sequences. |
| Serial Interface | SCI module compatible with UART protocol; enables host communication, debug logging, and peripheral coordination at configurable baud rates. |
Pinout & Package
DF3064BF25V is housed in a 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch) package. Pin assignments follow the H8/3064F-ZTAT B-mask version layout, including dedicated VCL pin requiring external capacitor for internal voltage regulation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCL | Voltage Control Line | Connects external capacitor to stabilize internal step-down regulator; required for reliable flash operation at 25 MHz. |
| XTAL1/XTAL2 | Clock Input/Output | Drives on-chip oscillator circuit with external crystal or resonator; determines system timing base and peripheral clock domains. |
| RESET | Active-Low Reset Input | Asynchronous reset signal; must be held low during power-up until supply stabilizes and VCL capacitor charges. |
| AD0–AD7 | Analog Input Channels | Eight dedicated pins for 10-bit A/D conversion; support simultaneous sampling when used with external trigger sources. |
| DA0 | Digital-to-Analog Output | Single 8-bit DAC output pin; provides calibrated analog voltage for feedback loops or calibration references. |
| TXD/RXD | SCI Transmit/Receive | Full-duplex UART interface pins; enable firmware updates, diagnostics, and host coordination without additional level-shifting ICs. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F3062B | 128 KB flash, 4 KB RAM, same H8/300H core and peripheral set; lacks VCL pin and internal step-down circuit. | Lower memory capacity and no internal voltage regulation; suitable for simpler control tasks with lower code footprint and fixed power rail. | Select HD64F3062B when flash size and internal regulator are not required, and board-level 3.3 V regulation is already present. |
| HD6433064B | 256 KB masked ROM (not reprogrammable), 8 KB RAM, identical pinout and peripheral complement to DF3064BF25V. | No field firmware update capability; intended for high-volume, stable-function applications where ROM cost and security outweigh flexibility needs. | Choose HD6433064B for production runs with finalized firmware and strict cost targets, accepting permanent code storage. |
Compared with DF3064BF25V, HD64F3062B offers reduced memory and no internal regulator - lowering BOM cost but increasing power design complexity; HD6433064B replaces flash with mask ROM, eliminating reprogrammability but improving unit cost and boot reliability in fixed-function deployments.

FAQ
What is the maximum operating frequency of the DF3064BF25V?
The DF3064BF25V supports a maximum system clock frequency of 25 MHz, enabled by its internal step-down regulator and VCL pin configuration. This frequency applies to both CPU execution and peripheral operation, and requires proper external crystal/resonator selection and VCL capacitor placement per Renesas Hardware Manual Rev.6.00. The DF3064BF25V achieves deterministic real-time performance at this speed due to its H8/300H core architecture and on-chip bus structure.
Does the DF3064BF25V include on-chip flash memory, and is it reprogrammable?
Yes, the DF3064BF25V integrates 256 KB of on-chip F-ZTAT™ flash memory that supports in-system programming (ISP) and in-application programming (IAP). This allows full firmware updates without removing the DF3064BF25V from the PCB or using external programmers. The flash is rated for 10,000 write/erase cycles and retains data for 20 years at 85°C, making it suitable for field-deployed equipment requiring remote maintenance.
What analog peripherals are integrated into the DF3064BF25V?
The DF3064BF25V includes a 10-bit successive approximation register (SAR) A/D converter with 8 input channels and a single 8-bit D/A converter. These are fully integrated with the CPU's interrupt and DMA controllers, enabling autonomous sampling triggered by timers or external events. The A/D converter supports differential input modes and built-in offset calibration, while the D/A converter provides monotonic output across its full range - both essential for precision control loops implemented on the DF3064BF25V.
Is the DF3064BF25V pin-compatible with other members of the H8/3062 Group?
The DF3064BF25V shares the same 100-pin LQFP package and pin assignment as the H8/3064F-ZTAT B-mask version, including identical VCL, XTAL, RESET, and peripheral I/O locations. However, it is not pin-compatible with R-mask versions (e.g., HD64F3062R) or masked ROM variants lacking VCL functionality. Board designs targeting DF3064BF25V must implement the VCL capacitor; substitution with non-VCL parts requires schematic and layout revision.
What development tools are officially supported for the DF3064BF25V?
Renesas officially supports the High-performance Embedded Workshop 3 IDE, H8S/H8/300 Series C/C++ Compiler (REJ10B0161), and associated debuggers for the DF3064BF25V. The H8/300H Series Programming Manual and H8/3062 Hardware Manual (Rev.6.00) provide complete register definitions, timing diagrams, and peripheral initialization sequences. Renesas also offers application notes on flash programming, A/D calibration, and TPC waveform generation specific to the DF3064BF25V and its family.
