Product details
Overview
HD64F3437TF16 from Renesas Electronics is a 16-bit single-chip microcontroller based on the H8/300 CPU core, featuring 60 KB on-chip flash memory (F-ZTAT™), 2 KB RAM, and integrated peripherals including SCI, A/D converter, D/A converter, timers, keyboard controller, and host interface (HIF). It operates at up to 16 MHz with 5 V supply and targets embedded control in industrial instrumentation and motor control systems.
For engineers reviewing the HD64F3437TF16 datasheet, HD64F3437TF16 pinout, HD64F3437TF16 application, or HD64F3437TF16 equivalent, key selection considerations include its single-power-supply flash programming capability (VCC-only), 100-pin TQFP package, boot/user/writer programming modes, and compatibility with Hitachi/Renesas development tools such as E6000 emulator and HS3437ECH61H cable.
Technical Context
The HD64F3437TF16 implements the H8/300 32-bit internal architecture with 16-bit external bus interface and supports three flash programming modes: writer mode, boot mode, and user programming mode - all enabled via software register control (FLSHE bit) without external 12 V VPP. Its flash memory is partitioned into eight erase blocks (EB0–EB7) totaling 60 KB, with block sizes ranging from 1 KB to 24 KB.
It integrates a 10-bit A/D converter with 8 channels, a 8-bit D/A converter, four 16-bit timers (including PWM-capable timer units), and an asynchronous serial interface (SCI) supporting full-duplex communication. The device uses a single 5 V supply for both logic and flash programming, eliminating the need for dedicated FVPP pins or external high-voltage circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | H8/300 16-bit instruction set with 32-bit internal data path; enables efficient C compilation and real-time interrupt handling. |
| Flash Memory | 60 KB on-chip F-ZTAT™ flash; supports in-system programming via VCC (5 V ±10%), no external 12 V required. |
| RAM Size | 2 KB on-chip SRAM; sufficient for stack, variables, and small buffers in standalone embedded applications. |
| Max Clock Frequency | 16 MHz system clock; delivers ~16 MIPS performance suitable for mid-complexity control loops. |
| A/D Converter | 10-bit resolution, 8-channel multiplexed input; supports sampling rates up to 100 kSPS for sensor interfacing. |
| D/A Converter | 8-bit resolution, single-channel output; provides analog actuator control or reference voltage generation. |
| Package | 100-pin TQFP (TF16); 14 mm × 14 mm footprint with 0.5 mm pitch, compatible with standard SMT reflow profiles. |
Pinout & Package
HD64F3437TF16 is housed in a 100-pin Thin Quad Flat Package (TQFP), designated TF16 per Renesas marking convention. The package supports fine-pitch surface-mount assembly and thermal dissipation adequate for industrial ambient temperatures (–20°C to +75°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC, VSS | Power supply and ground | Dual VCC (pins 14, 51, 87) and VSS (pins 13, 50, 86) pins ensure low-noise power distribution across analog/digital domains. |
| RES | Active-low reset input | Asynchronous reset requiring ≥20 system clock cycles low pulse for reliable initialization in single-power-supply mode. |
| MD0, MD1 | Mode select inputs | Fixed low during normal operation; used only during boot mode entry in dual-supply variants - not functional in HD64F3437TF16 (S-mask model). |
| P90–P92 | Port 9 I/O pins | Used for boot mode configuration in dual-supply parts; in HD64F3437TF16, these are general-purpose I/O with no boot function. |
| STBY | Standby control (dual-supply only) | Not connected in HD64F3437TF16; pin is NC (no internal connection) per S-mask design. |
| FVPP/STBY | Flash programming voltage / standby | NC in HD64F3437TF16; flash programming uses VCC only - eliminates need for external 12 V source. |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply flash programming | Enables field firmware updates using only 5 V VCC - removes requirement for high-voltage programming hardware or board-level VPP circuitry. |
| Integrated A/D and D/A converters | Reduces BOM count by eliminating external ADC/DAC ICs in closed-loop control applications like motor drives or sensor conditioning. |
| Host Interface (HIF) | Allows direct connection to host processors or FPGAs for firmware loading or data exchange without UART translation. |
| Keyboard controller | Supports up to 64-key matrix scanning with debounce and interrupt generation - ideal for HMI panels in industrial equipment. |
| Four 16-bit timers | Includes input capture, output compare, and PWM generation; enables precise timing for motor commutation or pulse-width modulation. |

FAQ
What is the flash programming voltage requirement for HD64F3437TF16?
The HD64F3437TF16 uses single-power-supply flash programming: only 5 V VCC (±10%) is required. Unlike dual-supply variants, it has no FVPP pin and does not accept 12 V - applying 12 V to any pin may permanently damage the device. Programming is controlled entirely via internal registers (FLMCR1/FLMCR2) and software commands.
Does HD64F3437TF16 support boot mode entry via hardware pin configuration?
No. HD64F3437TF16 is an S-mask (single-power-supply) variant and does not use MD0/MD1 or P90–P92 pin states to enter boot mode. Boot mode is entered exclusively through software register settings (e.g., setting FLSHE bit and writing to FLMCR1), eliminating dependency on external voltage levels or pin strapping.
What development tools are compatible with HD64F3437TF16?
HD64F3437TF16 is supported by Renesas' E6000 emulator (HS3008EPI60H), user cable HS3437ECH61H, and Windows interface software HS6400FWIW2SF. Flash programming can be performed via on-board writer mode or external PROM programmers like DATA I/O UNISITE or Minato 1892 configured for 64 KB Hitachi flash devices.
Is HD64F3437TF16 pin-compatible with older HD6473437 mask ROM versions?
Yes. HD64F3437TF16 maintains identical pinout, package (100-pin TQFP), and peripheral register mapping as the HD6473437 and HD6433437 mask ROM variants. This allows direct PCB replacement in legacy designs, upgrading from one-time-programmable ROM to field-reprogrammable flash without layout changes.
What is the maximum operating temperature range for HD64F3437TF16?
HD64F3437TF16 is rated for industrial temperature operation from –20°C to +75°C. It belongs to Renesas' "Standard" quality grade, intended for applications including industrial robots, test equipment, and office automation - not certified for automotive, medical life-support, or aerospace use without additional qualification.
