Product details
Overview
HD64F3337YTFLH16 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™), 4 KB RAM, and integrated peripherals including four timers, SCI, A/D converter (8-channel, 10-bit), D/A converter (2-channel, 8-bit), and keyboard controller. It operates at up to 16 MHz and targets embedded control in industrial instrumentation and motor drive systems.
For engineers reviewing the HD64F3337YTFLH16 datasheet, HD64F3337YTFLH16 pinout, HD64F3337YTFLH16 application, or HD64F3337YTFLH16 equivalent, key selection criteria include its single-power-supply flash programming capability (VCC only), 80-pin TQFP package, 5 V operation, and support for boot-mode and user-programming modes without external 12 V supply.
Technical Context
The HD64F3337YTFLH16 belongs to the H8/3337YF series and implements the S-mask (single-power-supply) flash variant - eliminating the FVPP pin and enabling in-system programming using only VCC (5.0 V ±10%). Its flash memory is organized into eight erase blocks (EB0–EB7), with block sizes ranging from 1 KB to 28 KB, and supports 32-byte-unit programming.
It integrates an H8/300H CPU core with 32-bit internal architecture, supports multiple operating modes (user, boot, writer), and includes dedicated flash control registers (FLMCR1/FLMCR2, EBR1/EBR2) for precise block-level erase and program control. The device uses MD0/MD1 pins and P90–P92 for mode selection, with no 12 V dependency for boot or programming entry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | H8/300H 16-bit core with 32-bit internal data path; enables efficient real-time control code execution. |
| Flash Memory | 60 KB on-chip F-ZTAT™ flash; supports single-VCC (5 V) programming and 32-byte write granularity. |
| RAM | 4 KB on-chip SRAM; sufficient for stack, variables, and small buffers in standalone embedded applications. |
| ADC | 8-channel, 10-bit successive-approximation ADC; provides precision analog sensing for motor current/voltage feedback. |
| DAC | 2-channel, 8-bit voltage-output DAC; enables analog waveform generation or reference setting for closed-loop control. |
| Timers | Four independent 16-bit timers (including PWM-capable channels); suitable for motor phase timing and pulse-width modulation. |

Pinout & Package
HD64F3337YTFLH16 is housed in an 80-pin Thin Quad Flat Package (TQFP), lead-free and RoHS-compliant, with 0.5 mm pitch and exposed thermal pad. Package dimensions are 12 mm × 12 mm × 1.4 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC, VSS | Power supply and ground | Dual VCC (pins 12, 35, 58, 80) and VSS (pins 11, 34, 57, 79) reduce noise and improve decoupling for mixed-signal operation. |
| RES | Active-low reset input | Asynchronous reset requiring ≥20 system clock cycles low pulse in S-mask mode; ensures reliable initialization after power-up or fault recovery. |
| MD0, MD1 | Mode select inputs | Configure boot/user/writer modes; in S-mask version, MD1 is not driven by 12 V but used as logic input (low = boot mode). |
| P90–P92 | Boot mode configuration | Three GPIO pins used during reset to define boot entry condition; eliminates need for external voltage switching circuitry. |
| XTAL, EXTAL | Crystal oscillator inputs | Supports 1–16 MHz crystal or external clock source; enables precise timing for serial communication and PWM generation. |
| SCI_TXD, SCI_RXD | Serial communication interface | Full-duplex asynchronous UART interface; allows host debugging, firmware updates, or sensor telemetry without additional transceivers. |
| AD0–AD7 | Analog input channels | Eight dedicated analog inputs mapped to internal 10-bit ADC; supports simultaneous sampling of motor phase currents and temperature sensors. |
| DA0, DA1 | Digital-to-analog outputs | Two buffered 8-bit DAC outputs; provide programmable reference voltages for comparator thresholds or analog actuator control signals. |
Key Features
| Feature | Design Value |
|---|---|
| Single-VCC Flash Programming | Eliminates need for 12 V programming supply; reduces BOM cost and simplifies PCB layout for field firmware updates. |
| Integrated A/D + D/A Converters | Enables closed-loop analog control (e.g., motor speed regulation) without external signal conditioning ICs. |
| Four 16-bit Timers with PWM | Supports three-phase motor commutation timing, dead-time insertion, and encoder counting in one chip. |
| SCI + Keyboard Controller | Allows direct connection to PC via RS-232 (with level shifter) and matrix keypad for HMI, reducing external interface components. |
| Boot Mode Entry via GPIO | Uses P90–P92 and MD0/MD1 as logic-level inputs - avoids high-voltage sequencing and improves system reliability. |

FAQ
What is the flash programming voltage requirement for HD64F3337YTFLH16?
The HD64F3337YTFLH16 uses single-power-supply (S-mask) flash technology and requires only VCC (5.0 V ±10%) for all programming and erasing operations. Unlike dual-supply variants, it does not require a 12 V FVPP supply, eliminating the need for external high-voltage circuitry and simplifying in-system firmware updates.
Does HD64F3337YTFLH16 support boot mode entry without 12 V?
Yes. HD64F3337YTFLH16 enters boot mode using logic-level signals on MD0, MD1, and P90–P92 pins during reset - no 12 V application is needed. This distinguishes it from dual-power-supply versions and enhances reliability in industrial environments where high-voltage sequencing adds complexity.
What are the key differences between HD64F3337YTFLH16 and HD64F3337YF16?
HD64F3337YTFLH16 is the S-mask (single-VCC) variant, while HD64F3337YF16 is the dual-supply version requiring 12 V on FVPP/STBY for programming. HD64F3337YTFLH16 removes the FVPP pin, reassigns MD1 as a logic input, and uses 32-byte programming units - making it incompatible with 12 V programmers but simpler to integrate.
Can HD64F3337YTFLH16 be used in automotive applications?
No. HD64F3337YTFLH16 is rated for Standard quality grade per Renesas documentation and is intended for industrial, office, and consumer equipment - not automotive, aerospace, or life-support systems. Its qualification excludes AEC-Q100 stress testing and extended temperature range operation required for vehicle ECUs.
What development tools support HD64F3337YTFLH16 programming?
Supported tools include Hitachi's HS3008EPI60H emulator with HS3437ECH61H cable, Minato and DATA I/O PROM programmers (e.g., 1892, UNISITE), and Hitachi Embedded Workshop IDE. Programming requires socket adapters compatible with 80-pin TQFP and firmware that recognizes the S-mask flash command set - not the HN28F101 12 V mode.
