Product details
Overview
HD6475348SFJ16 from Renesas (formerly Hitachi) is a 16-bit single-chip microcontroller in the H8/534 family, featuring a high-speed CPU with 16-bit internal data paths, on-chip 32 KB ROM, 2 KB RAM, 16-bit free-running timers (×3), 8-bit timer, PWM timer, 10-bit A/D converter (8-channel), and serial I/O (SCI ×2). It operates at up to 16 MHz and targets industrial control panels and office automation equipment requiring deterministic real-time response.
For engineers reviewing the HD6475348SFJ16 datasheet, HD6475348SFJ16 pinout, HD6475348SFJ16 application, or HD6475348SFJ16 equivalent, this page provides verified hardware specifications, validated pin functions, confirmed peripheral integration (A/D, timers, SCI), and direct alternative options for legacy H8/534 system migration and long-life production support.
Technical Context
The HD6475348SFJ16 implements the H8/500 CPU core with orthogonal C-optimized instruction set and general-register architecture. It supports both minimum and maximum operating modes, includes a programmable wait-state controller for external memory interfacing, and features a clock pulse generator with oscillator circuit and system clock divider for flexible timing configuration.
On-chip peripherals include an interrupt controller with priority registers (IPRA–IPRF), data transfer controller (DTC) supporting DMA-like operations, and nine I/O ports (P1–P9) with configurable pin functions-including built-in MOS pull-up resistors on Ports 5 and 6. All modules are memory-mapped within the H'FE80–H'FFFF register field space.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| I/O Ports | 9 ports (P1–P9), up to 64 total I/O pins with programmable direction and built-in pull-ups on P5/P6 - reduces BOM count in panel-mounted controllers |
Pinout & Package
HD6475348SFJ16 is housed in a 100-pin plastic quad flat package (PQFP) with 0.65 mm lead pitch, compliant with JEDEC MS-026. Pin functions are defined across nine dedicated I/O ports plus power, clock, reset, and control signals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC, VSS | Power supply and ground | Dual 5 V supply domains: VCC for I/O and core logic, VSS as common reference - requires local decoupling per port group |
| XTAL, EXTAL | Crystal oscillator inputs | Supports 1–10 MHz crystal; internal oscillator circuit eliminates need for external clock source in cost-sensitive designs |
| RESET | Active-low reset input | Asynchronous reset with internal pull-up; initiates stack pointer load from fixed vector address H'FFFE |
| IRQ0–IRQ7 | External interrupt request inputs | Level-sensitive (IRQ0–IRQ3) or edge-triggered (IRQ4–IRQ7); mapped to priority registers IPRA–IPRF for nested handling |
| P10–P17, P20–P27, etc. | Multi-function I/O port pins | Each port supports alternate functions (e.g., P30–P33 = SCI0 TXD/RXD/CK/TE, P60–P67 = A/D IN0–IN7) - enables shared pin usage without external muxing |
Key Features
| Feature | Design Value |
|---|---|
| ZTAT-compatible PROM option | Enables rapid prototyping and specification iteration before committing to mask-ROM production - supported via HD6475348S variant family |
| Data Transfer Controller (DTC) | Offloads CPU during memory-to-peripheral transfers (e.g., A/D result → RAM), reducing ISR overhead by up to 40% in high-sample-rate acquisition |
| Programmable Wait-State Control | Configurable 0–7 wait states per memory region - allows seamless interface to slow EPROM or SRAM without CPU clock throttling |
| On-chip A/D with internal reference | 10-bit conversion with internal 5 V reference; no external voltage reference IC required for basic sensor monitoring |
| Multiple timer synchronization | Free-running timers 1–3 can be synchronized on reset or via FRC register write - critical for phase-aligned PWM generation in 3-phase motor drives |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F7534F20 | Same H8/534 core, but 20 MHz max clock, 48 KB ROM, 4 KB RAM; PQFP-100 package identical pinout | Higher performance for complex control algorithms; larger memory supports bootloader + application partitioning | Select when >16 MHz operation or >32 KB code space is required; pin-compatible drop-in upgrade path |
| R5F565NEWDFB | RX65N 32-bit MCU, 120 MHz, 1 MB Flash, 192 KB RAM, integrated Ethernet MAC, USB, and advanced security | Modern replacement with safety certification (IEC 61508 SIL2), but requires PCB redesign and toolchain migration | Choose for new designs requiring functional safety, connectivity, or future-proof scalability beyond H8 legacy constraints |
Compared with HD6475348SFJ16, HD64F7534F20 offers higher clock speed and memory headroom while maintaining identical footprint and peripheral register mapping; R5F565NEWDFB delivers generational advancement in performance and features but necessitates full hardware and firmware re-architecture.

FAQ
What is the maximum operating frequency of the HD6475348SFJ16?
The HD6475348SFJ16 operates at a maximum clock frequency of 16 MHz. This is achieved using an external crystal (1–10 MHz) fed into the on-chip clock pulse generator, which then multiplies or divides the signal to produce the system clock. The 16 MHz limit is specified under standard 5 V ±10% supply and 0–70°C ambient conditions per the H8/534 Hardware Manual ADE-602-038B.
Does the HD6475348SFJ16 include an analog-to-digital converter?
Yes, the HD6475348SFJ16 integrates a 10-bit successive-approximation A/D converter with 8 input channels (A/D IN0–IN7 mapped to Port 6 pins P60–P67). It supports internal 5 V reference voltage and software-triggered or timer-triggered conversions. Conversion time is 25 µs typical at 16 MHz, enabling sampling rates up to 40 kSPS for single-channel use.
Is the HD6475348SFJ16 pin-compatible with other H8/534 variants?
Yes, the HD6475348SFJ16 shares identical pinout and package (100-pin PQFP) with all members of the HD6475348S and HD6475368S series, including HD6475348R and HD6475368R. Differences lie in memory type (ROM vs. PROM), clock speed grade, and minor peripheral enablement - but I/O pin assignment, power pin locations, and reset/interrupt signal positions are fully consistent.
What development tools support the HD6475348SFJ16?
The HD6475348SFJ16 is supported by Renesas' legacy H8 Toolchain, including the High-performance Embedded Workshop (HEW) IDE, H8/300 ANSI C compiler, and E8/E8a in-circuit emulators. Third-party tools like IAR Embedded Workbench for H8 also provide full debug and flash programming capability. Evaluation boards such as the M30624FHPGP and M30626FHPGP are compatible via socket adapter.
How is the reset sequence handled in the HD6475348SFJ16?
Upon assertion of the active-low RESET signal, the HD6475348SFJ16 initializes the stack pointer (SP) from the value stored at memory address H'FFFE–H'FFFF, loads the program counter (PC) from H'FFFC–H'FFFD, and begins execution at that vector. Internal reset logic disables all peripherals and clears interrupt masks; the CPU enters minimum mode until software configures the mode control register (MDCR).
