Product details
Overview
HD6473334YFJ16 from Renesas Technology Corp. is a single-chip 16-bit microcontroller based on the H8/300 CPU core, featuring 64 KB on-chip flash memory (F-ZTAT™), 4 KB RAM, four 16-bit timers, SCI, A/D converter, D/A converter, and I/O ports - designed for embedded control in industrial automation and motor drive systems.
For engineers reviewing the HD6473334YFJ16 datasheet, HD6473334YFJ16 pinout, HD6473334YFJ16 application, or HD6473334YFJ16 equivalent, this part supports single-power-supply flash programming (VCC only), operates at up to 16 MHz, and integrates boot-mode configuration via P92/P91/P90 pins - critical for firmware update reliability and BOM consolidation in volume production.
Technical Context
The HD6473334YFJ16 implements the H8/300 32-bit internal architecture with 16-bit external bus interface, supporting both user programming mode and boot mode via software-controlled FLSHE bit and hardware pin settings (P92–P90 = 111). It uses a single 5 V ±10% supply for flash programming - eliminating need for external 12 V VPP.
Its peripheral set includes an 8-channel 10-bit A/D converter with sample-and-hold, a 2-channel 8-bit D/A converter, asynchronous serial interface (SCI) with framing/error detection, and host interface (HIF) for system expansion - all synchronized to the same on-chip clock generator with programmable prescaler and duty adjustment circuit.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | H8/300 16-bit instruction set, 32-bit internal data path - enables efficient C compilation and deterministic real-time interrupt response. |
| Flash Memory | 64 KB F-ZTAT™ flash (single-power-supply), organized as 60 KB programmable blocks - supports in-system reprogramming without external high-voltage supply. |
| RAM | 4 KB on-chip SRAM - sufficient for stack, variables, and buffer storage in closed-loop motor control applications. |
| Max Clock Frequency | 16 MHz system clock - delivers ~16 MIPS throughput for time-critical PWM generation and sensor sampling. |
| A/D Converter | 8-channel, 10-bit successive-approximation ADC with sample-and-hold - supports simultaneous sampling of multiple analog inputs (e.g., current/voltage/temperature). |
| D/A Converter | 2-channel, 8-bit voltage-output DAC - provides analog reference or bias signals for op-amp conditioning circuits. |
| Serial Interface | Asynchronous SCI with full-duplex operation, framing error detection, and programmable baud rate - suitable for host communication or debug logging. |
| Package | 80-pin PQFP (FP-80A), 14 × 20 mm body, 0.65 mm pitch - compatible with standard surface-mount assembly and thermal management in industrial PCBs. |
Pinout & Package
HD6473334YFJ16 is housed in an 80-pin Plastic Quad Flat Package (PQFP), designated FP-80A per Hitachi/Renesas mechanical specification - footprint matches industry-standard 0.65 mm pitch layout with exposed thermal pad option (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply / Ground | Single 5 V ±10% supply powers core, peripherals, and flash programming - eliminates dual-rail design complexity. |
| P92, P91, P90 | Boot mode select inputs | Hardwired high (111) at reset release enters boot mode - enables firmware update without external programmer connection. |
| RES | Active-low reset input | Minimum 20 system clock cycles low required for reliable reset - ensures stable initialization after power-up or brownout recovery. |
| MD0, MD1 | Mode select inputs | Fixed low (00) configures single-power-supply operation - disables FVPP pin function and enables VCC-based flash write. |
| STBY | Standby control (dual-supply only) | No function in HD6473334YFJ16 - NC in single-power-supply variant; must be left unconnected per datasheet caution. |
| XTAL1 / XTAL2 | Crystal oscillator inputs | Supports 1–16 MHz crystal or external clock source - direct drive of on-chip oscillator circuit without external components. |
Key Features
| Feature | Design Value |
|---|---|
| F-ZTAT™ Flash Architecture | 64 KB on-chip flash with 32-byte-unit programming and block-erase capability - reduces firmware update time and improves field upgrade robustness. |
| Integrated Analog Peripherals | 8-channel 10-bit A/D + 2-channel 8-bit D/A - enables closed-loop analog control (e.g., motor current regulation) without external converters. |
| Hardware Boot Mode Entry | P92/P91/P90 = 111 at reset - guarantees deterministic entry into bootloader without software dependency or timing-critical register writes. |
| Single-Supply Flash Programming | VCC-only (5 V) programming - removes need for 12 V charge pump or external VPP circuitry, simplifying power design and reducing BOM cost. |
| SCI with Framing Error Detection | Asynchronous serial interface with automatic framing error flag - prevents corrupted command execution during noisy industrial communications. |
| On-Chip Wait-State Controller | Configurable zero-to-three wait states for external memory access - maintains timing compliance across varying bus speeds and memory types. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F3334Y | Dual-power-supply variant requiring 12 V on FVPP pin for flash programming; includes STBY pin functionality. | Suitable where legacy 12 V programming infrastructure exists; not pin-compatible due to FVPP/STBY pin assignment and boot mode pin logic. | Select HD64F3334Y only if existing test fixtures supply 12 V and require backward compatibility with older ZTAT® PROM-based toolchains. |
| HD6473334Y | Mask ROM version (no flash); fixed firmware, no field update capability; identical pinout and peripheral set. | Used in cost-sensitive, high-volume applications where firmware never changes - e.g., consumer appliance motor controllers. | Choose HD6473334Y when lifecycle stability and lowest unit cost outweigh field-upgrade flexibility. |
Compared with HD64F3334Y, HD6473334YFJ16 eliminates external VPP circuitry and simplifies power design; compared with HD6473334Y, it trades mask ROM permanence for in-field firmware agility - making it optimal for prototyping, mid-volume industrial equipment, and applications requiring regulatory recertification support.

FAQ
What is the flash programming voltage requirement for HD6473334YFJ16?
HD6473334YFJ16 requires only a single 5 V ±10% supply (VCC) for flash programming - no external 12 V VPP is needed. This is enabled by its single-power-supply S-mask flash architecture, which internally generates programming voltages from VCC. Using 12 V on any pin (e.g., MD1 or STBY) will permanently damage the device, as confirmed in the Hardware Manual Section "Notes on S-Mask Model".
Does HD6473334YFJ16 support boot mode entry without external hardware changes?
Yes. HD6473334YFJ16 enters boot mode automatically when P92, P91, and P90 are all pulled high (logic 1) at reset release - no external jumper or mode switch is required. This hardware-triggered entry ensures deterministic bootloader activation for firmware updates, and is explicitly defined in Table 4 ("H8/3337YF and H8/3337F S-Mask Model Pin Settings") of the Hardware Manual.
What package type and pin count does HD6473334YFJ16 use?
HD6473334YFJ16 uses an 80-pin Plastic Quad Flat Package (PQFP), designated FP-80A per Renesas mechanical drawings - with 14 mm × 20 mm body size and 0.65 mm lead pitch. Pin arrangement matches Figure 1.2(a) in the Hardware Manual, and the "J16" suffix in the part number confirms this FP-80A packaging variant.
Can HD6473334YFJ16 execute code while programming flash memory?
No. HD6473334YFJ16 cannot execute code from flash during programming or erase operations - the flash memory controller halts CPU access to the target block. The device supports only 32-byte-unit programming and requires EBR1/EBR2 register setup before writing, as specified in Section 21.2.2 of the Hardware Manual. Execution must occur from RAM or wait-state-controlled external memory during flash updates.
Is HD6473334YFJ16 pin-compatible with HD64F3334Y?
No. Although both share the same FP-80A package and core peripheral set, HD6473334YFJ16 repurposes the FVPP/STBY pin as NC (not connected), while HD64F3334Y uses it for 12 V flash programming and standby control. Table 4 in the Hardware Manual confirms differing pin functions and boot mode entry methods - making them incompatible for drop-in replacement without PCB redesign.
