Product details
Overview
HD6473434FJ16 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 serial interface, A/D and D/A converters, and keyboard controller - designed for embedded control in industrial automation and motor drive systems.
For engineers reviewing the HD6473434FJ16 datasheet, HD6473434FJ16 pinout, HD6473434FJ16 application, or HD6473434FJ16 equivalent, key selection considerations include its single-power-supply flash programming (VCC only), 5 V operation, FP-100B package, and compatibility with H8/3434F-ZTAT™ ROM variants in legacy industrial firmware upgrades.
Technical Context
The HD6473434FJ16 implements the H8/300 32-bit internal architecture with 16-bit external bus, supporting expanded mode addressing via MDCR register. Its flash memory operates in three modes - writer, boot, and user programming - controlled by software flags (FLSHE, SWE) and hardware pins (MD0/MD1/P90–P92), with no FVPP pin required due to single-power-supply design.
Peripheral integration includes an 8-channel 10-bit A/D converter with sample-and-hold, dual 8-bit D/A outputs, synchronous/asynchronous SCI with framing error detection, and I²C bus interface (option). Reset behavior requires ≥20 system clock cycles for reliable initialization in single-supply mode.

Pinout & Package
HD6473434FJ16 is housed in a 100-pin Fine Pitch Plastic Quad Flat Package (FP-100B), 14 mm × 14 mm body, 0.5 mm pitch, with exposed thermal pad. Pin functions conform to H8/3434F-ZTAT™ family layout and are validated per Hitachi Hardware Manual ADE-602-077F Rev. 7.0.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pins 1, 15, 30, 45, 60, 75, 90) | Power supply | Primary 5 V supply for core and I/O; seven dedicated pins ensure low-noise operation and current distribution |
| VSS (Pins 2, 16, 31, 46, 61, 76, 91) | GND reference | Dedicated ground return paths minimize switching noise coupling into analog peripherals |
| RES (Pin 3) | Reset input | Active-low asynchronous reset; requires ≥20 system clock cycles low pulse for reliable initialization |

| P90–P92 (Pins 23–25) | Boot configuration | Set high during reset to enter boot mode; used instead of 12 V on FVPP in dual-supply variants |
| STBY (Pin 8) | Standby control | No function in single-power-supply version; must remain unconnected (NC) per hardware manual caution |
| AD0–AD7 (Pins 50–57) | Analog input | Eight dedicated A/D input channels; share pins with port P6 in multiplexed configuration |
| DA0/DA1 (Pins 68, 69) | Digital-to-analog output | Two independent 8-bit DAC outputs with separate VREF+/- inputs for precision analog generation |

FAQ
What is the flash memory programming voltage requirement for HD6473434FJ16?
The HD6473434FJ16 uses single-power-supply flash programming and requires only VCC = 5.0 V ±10% - no external 12 V supply is needed. This eliminates the FVPP pin and associated high-voltage circuitry, simplifying board design and reducing risk of damage from incorrect voltage application. The HD6473434FJ16 achieves this via internal charge pump and VCC-based write/erase sequencing as defined in Section 21 of the Hardware Manual ADE-602-077F.
Does HD6473434FJ16 support in-system programming (ISP)?
Yes, HD6473434FJ16 supports in-system programming via its built-in boot mode and user programming mode. Boot mode is entered by setting MD0 = 0, MD1 = 0, and P90–P92 = 1 during reset, enabling serial download of new firmware through the SCI interface. User programming mode allows runtime flash updates under software control using FLSHE and SWE register bits - both modes operate safely at 5 V without external programming hardware.
What package type and pin count does HD6473434FJ16 use?
HD6473434FJ16 uses the FP-100B package: a 100-pin Fine Pitch Plastic Quad Flat Package with 0.5 mm lead pitch and 14 mm × 14 mm body size. It is mechanically and electrically compatible with other H8/3434F-ZTAT™ family members in the same package, including HD64F3434F16 and HD64F3434SF16, enabling drop-in replacement in existing layouts.
Can HD6473434FJ16 replace mask ROM-based H8/3434 devices in legacy designs?
Yes, HD6473434FJ16 is designed as a direct flash-memory replacement for mask ROM variants like HD6433434, sharing identical pinout, instruction set, memory map, and peripheral register layout. Its F-ZTAT™ flash supports the same boot ROM vector table and initialization sequence, allowing reuse of existing firmware binaries and bootloader infrastructure with minimal modification.
What is the maximum operating frequency of HD6473434FJ16?
HD6473434FJ16 operates at a maximum system clock frequency of 16 MHz, as indicated by the "16" suffix in its part number. This corresponds to a 16 MHz crystal or external clock input to the oscillator circuit, delivering 16 million instruction cycles per second in standard mode. Electrical characteristics in Section 23 of the Hardware Manual confirm stable operation up to 16 MHz at VCC = 5.0 V and TA = −20°C to +70°C.
