Product details
Overview
HD64F3437TF16V from Renesas Technology Corp. is a 16-bit H8/300-based single-chip microcontroller with 60 KB on-chip flash memory (F-ZTAT™), 4 KB RAM, and integrated peripherals including SCI, A/D converter, D/A converter, keyboard controller, and four timers. It operates at up to 16 MHz and supports single-power-supply flash programming at VCC = 5.0 V ±10%. It targets embedded control systems requiring field-upgradable firmware and compact system integration.
For engineers reviewing the HD64F3437TF16V datasheet, HD64F3437TF16V pinout, HD64F3437TF16V application, or HD64F3437TF16V equivalent, key selection criteria include its 100-pin TFP package, 5 V operation, S-mask flash architecture, boot/user programming modes, and compatibility with Hitachi H8/3437F-series development tools and register-level software.
Technical Context
The HD64F3437TF16V implements the H8/300 CPU core with 32-bit internal architecture and Harvard-style memory organization. It features dual operating modes-user mode and boot mode-with distinct memory mapping and register access permissions. Flash memory is organized into eight erase blocks (EB0–EB7) totaling 60 KB, managed via EBR1/EBR2 registers and controlled by FLMCR1/FLMCR2.
Its peripheral set includes a 10-bit A/D converter with 8 channels, an 8-bit D/A converter, asynchronous serial interface (SCI) supporting full-duplex communication, and a host interface (HIF) for external memory expansion. The device uses a single 5 V supply for both logic and flash programming-no external 12 V VPP required-distinguishing it from dual-power-supply variants like HD64F3437F16.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | H8/300 16-bit architecture with 32-bit internal data path; enables efficient C compilation and deterministic real-time interrupt response. |
| Flash Memory | 60 KB on-chip F-ZTAT™ flash; supports in-system programming via boot mode or user mode without external high-voltage supply. |
| RAM | 4 KB on-chip SRAM; mapped at fixed addresses for fast access by CPU and peripherals during active operation. |
| Max Clock Frequency | 16 MHz system clock; defines maximum instruction throughput and timing resolution for timers and A/D sampling. |
| A/D Converter | 10-bit resolution, 8-channel multiplexed input; provides analog sensing capability for industrial monitoring and motor control feedback. |
| D/A Converter | 8-bit resolution, single-channel output; enables analog waveform generation or bias voltage control in closed-loop systems. |
| Serial Interface | Asynchronous SCI with programmable baud rate; supports RS-232/RS-485 level-shifting for host communication or sensor telemetry. |
| Package | 100-pin TFP (Thin Fine Pitch) plastic QFP; 14 mm × 20 mm footprint with 0.5 mm pitch, suitable for high-density PCB layouts. |
Pinout & Package
HD64F3437TF16V is housed in a 100-pin Thin Fine Pitch Quad Flat Package (TFP-100B), with pins arranged in a 10×10 grid and pin 1 located at the bottom-left corner (viewed from top). The package supports standard reflow soldering and provides dedicated power (VCC/VSS), reset (RES), mode control (MD0/MD1), and peripheral I/O pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pins 14, 29, 44, 59, 74, 89) | Power Supply | Primary 5 V supply for core logic and I/O; six distributed pins reduce IR drop and improve noise immunity. |
| VSS (Pins 15, 30, 45, 60, 75, 90) | Ground | Digital ground reference; multiple pins ensure low-impedance return paths for switching currents. |
| RES (Pin 1) | Reset Input | Active-low asynchronous reset; must be held low ≥20 system clock cycles for reliable initialization in S-mask mode. |
| MD0, MD1 (Pins 2, 3) | Mode Select | Configure boot/user mode and memory mapping; in S-mask devices, these pins are sampled only at reset release. |
| P90–P92 (Pins 98–100) | Boot Configuration | Set to '1' to enter boot mode; no 12 V required-unlike dual-supply variants, eliminating external VPP circuitry. |
| STBY (Pin 8) | Standby Control | No function in S-mask version; must remain unconnected per NC pin handling guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Single-Power-Supply Flash Programming | Enables field firmware updates using only 5 V VCC-no external 12 V generator or isolation circuitry required. |
| On-Chip A/D + D/A Converters | Reduces BOM count and board area by integrating analog I/O; eliminates need for external ADC/DAC ICs in sensor interface designs. |
| Integrated Keyboard Controller | Supports up to 64-key matrix scanning with automatic debounce and interrupt-on-keypress-ideal for HMI panels and industrial control terminals. |
| Four Independent Timers | Includes 16-bit free-running, 8-bit PWM, 16-bit input capture, and watchdog timer-enables precise motor control, pulse measurement, and system safety monitoring. |
| HIF External Bus Interface | Provides 16-bit address/data multiplexed bus with wait-state control-allows seamless connection to external SRAM, EPROM, or FPGA co-processors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the flash programming voltage requirement for HD64F3437TF16V?
HD64F3437TF16V uses single-power-supply flash programming: only 5.0 V ±10% on VCC is required-no external 12 V VPP supply. This eliminates high-voltage circuitry and simplifies in-system programming. The device lacks an FVPP pin and does not support 12 V application on any terminal, including MD1 or STBY. Applying 12 V will permanently damage HD64F3437TF16V.
Does HD64F3437TF16V support boot mode entry without external high voltage?
Yes. HD64F3437TF16V enters boot mode by asserting MD0 = 0, MD1 = 0, P90 = 1, P91 = 1, P92 = 1 at reset release-no 12 V required. This contrasts with dual-supply variants that require 12 V on MD1. The boot ROM provides serial download capability and flash erase/write routines accessible via SCI, enabling firmware recovery and updates.
What peripherals are integrated into HD64F3437TF16V?
HD64F3437TF16V integrates a 10-bit 8-channel A/D converter, 8-bit D/A converter, asynchronous serial interface (SCI), host interface (HIF) for external memory, keyboard controller for 64-key matrix, four timers (including PWM and input capture), and I/O ports. These peripherals are register-mapped and fully documented in the Hardware Manual ADE-602-077F, enabling complete system integration without external support ICs.
Is HD64F3437TF16V pin-compatible with other H8/3437F-series microcontrollers?
HD64F3437TF16V shares the same 100-pin TFP-100B package and pinout as HD64F3437F16 and HD64F3437SF16, but functional pin assignments differ: HD64F3437F16 has an active FVPP/STBY pin (Pin 8), while HD64F3437TF16V treats Pin 8 as NC. Therefore, HD64F3437TF16V is not a drop-in replacement for HD64F3437F16 without PCB modification to isolate Pin 8.
What development tools are compatible with HD64F3437TF16V?
HD64F3437TF16V is supported by the E6000 emulator (HS3008EPI60H), HS3437ECH61H user cable, and HS0008EASF3H adapter board. Programming is performed using Hitachi HS6400FWIW2SF Windows software with DATA I/O UNISITE or Minato 1892-series programmers configured for 64 KB flash. The H8/300 Series Programming Manual (ADE-602-025) and Hardware Manual (ADE-602-077F) provide full register and instruction documentation for HD64F3437TF16V.
