Product details
Overview
HD6473337YCP16V from Renesas Technology Corp. is a 16-bit single-chip microcontroller based on the H8/300 CPU core, featuring 60 KB on-chip flash memory (ZTAT®), 2 KB RAM, four 16-bit timers, SCI serial interface, A/D and D/A converters, and I/O ports - designed for embedded control in industrial automation and motor drive systems.
For engineers reviewing the HD6473337YCP16V datasheet, HD6473337YCP16V pinout, HD6473337YCP16V application, or HD6473337YCP16V equivalent, key selection criteria include its 5 V operation, FP-80A 80-pin plastic QFP package, flash programming via VCC (single-power-supply mode), and compatibility with H8/300 instruction set architecture.
Technical Context
The HD6473337YCP16V implements the H8/300 32-bit internal architecture with 16-bit external data bus, supporting both minimum and expanded modes. It integrates system control logic including mode selection (MD0/MD1 pins), reset handling with configurable pulse width (≥20 system clock cycles), and wait-state controller for external memory interfacing.
Its flash memory subsystem uses FLSHE-enabled register access, supports 32-byte-unit programming, and requires no external 12 V VPP supply - distinguishing it from dual-power-supply variants. The device includes dedicated registers (FLMCR1/FLMCR2, EBR1/EBR2) for block-level erase and program control, with boot mode entry via P92–P90 pin configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | H8/300 32-bit internal architecture, 16-bit external bus - enables efficient C-language execution and real-time deterministic timing. |
| Flash Memory | 60 KB ZTAT® on-chip flash - supports in-system reprogramming without external VPP; erased/programmed in configurable blocks (e.g., LB0–LB7, SB0–SB7). |
| RAM | 2 KB on-chip SRAM - provides fast scratchpad and stack space; mapped at fixed addresses in all operating modes. |
| Operating Voltage | 5.0 V ±10% - single-supply operation eliminates need for auxiliary voltage rails; compatible with standard TTL/CMOS logic interfaces. |
| Package | FP-80A (80-pin plastic QFP, 14 × 20 mm, 0.65 mm pitch) - surface-mount compatible with industrial PCB assembly processes. |
| Max Clock Frequency | 16 MHz - defines real-time performance ceiling for timer resolution, SCI baud rate generation, and interrupt latency. |
| I/O Ports | 64-bit general-purpose I/O (Port 1–Port 8) with programmable pull-up, input/output direction control, and interrupt capability per pin group - enables direct sensor/actuator interfacing. |
Pinout & Package
HD6473337YCP16V is housed in an 80-pin plastic quad flat pack (FP-80A), with pins arranged in four 20-pin sides (top view, pin 1 at bottom-left corner). Pin functions follow H8/3337 Series standard assignment, including dedicated MD0/MD1 mode select, P90–P92 boot configuration, RES reset, and VCC/VSS power distribution across multiple pins for noise immunity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RES | Active-low reset input | Drives chip into known state; requires ≥20 system clock cycles low pulse for reliable initialization in single-power-supply mode. |
| MD0, MD1 | Mode selection inputs | Determine minimum/expanded mode and bus width; sampled at reset to configure address/data bus behavior and peripheral enable. |
| P90–P92 | Boot mode configuration | Set to high during reset to enter boot mode for flash programming; no external 12 V required (unlike dual-supply variants). |
| VCC (pins 12, 32, 52, 72) | Power supply | Four distributed 5 V inputs reduce IR drop and improve noise margin; must be decoupled locally with 0.1 µF ceramic capacitors. |
| VSS (pins 11, 31, 51, 71) | Ground reference | Four dedicated ground pins provide low-inductance return paths for digital and analog sections separately. |
Key Features
| Feature | Design Value |
|---|---|
| Single-power-supply flash programming | Eliminates need for external 12 V VPP generator; enables field firmware updates using only VCC (5 V), reducing BOM cost and board space. |
| Configurable erase/program blocks | Eight logical blocks (LB0–LB7, SB0–SB7) allow selective firmware updates without full-chip erase - critical for fail-safe over-the-air updates. |
| Dedicated boot mode entry | P90–P92 pin-driven boot sequence ensures reliable recovery and programming even after corrupted user code - no external programmer hardware required. |
| Integrated analog peripherals | 8-channel 10-bit A/D converter and 8-bit D/A converter support closed-loop control (e.g., motor current sensing and PWM offset correction) without external signal conditioning ICs. |
| H8/300 instruction set compatibility | Enables reuse of existing toolchains (C/C++ compiler, simulator debugger) and legacy firmware libraries - reduces development time and validation effort. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F3337YF16TF16 | Dual-power-supply flash variant requiring 12 V VPP for programming; includes FVPP/STBY pin; different boot mode entry (12 V on MD1). | Suitable for factory-programmed units where field updates are rare; incompatible with single-supply field programming infrastructure. | Select only if legacy tooling (e.g., HN28F101 programmer) and 12 V supply are available; not drop-in replaceable due to voltage and pin function differences. |
| HD6433337Y | Mask ROM version (no flash); fixed firmware; no in-system programming capability; identical CPU, peripherals, and pinout. | Used in high-volume, unchanging firmware deployments where cost-per-unit and security against tampering are priorities. | Choose when firmware is finalized and field updates are unnecessary; offers lower unit cost but zero flexibility post-manufacture. |
Compared with HD64F3337YF16TF16, HD6473337YCP16V eliminates external VPP circuitry and simplifies programming infrastructure, while HD6433337Y trades flash flexibility for mask-ROM cost and security - making HD6473337YCP16V optimal for updatable industrial controllers requiring field serviceability.

FAQ
What is the flash memory programming voltage requirement for HD6473337YCP16V?
HD6473337YCP16V uses single-power-supply flash programming: only 5.0 V ±10% (VCC) is required - no external 12 V VPP supply or FVPP pin. This eliminates high-voltage circuitry and simplifies field firmware updates. Programming is enabled via software-controlled FLSHE bit and executed in 32-byte units under control of FLMCR1/FLMCR2 registers.
Does HD6473337YCP16V support boot mode entry without external 12 V?
Yes. HD6473337YCP16V enters boot mode by asserting high levels on P90, P91, and P92 during reset release - no 12 V application is needed. This differs from dual-supply variants like HD64F3337YF16TF16, which require 12 V on MD1. The single-supply design ensures safe, low-voltage field recovery and programming.
What package type and pin count does HD6473337YCP16V use?
HD6473337YCP16V is packaged in an 80-pin plastic QFP (FP-80A) with 0.65 mm lead pitch and 14 mm × 20 mm body size. Pin 1 is located at the bottom-left corner (rotated 90° left from standard orientation). This package supports industrial temperature range operation and is compatible with standard reflow soldering profiles.
Can HD6473337YCP16V execute the full H8/300 instruction set?
Yes. HD6473337YCP16V implements the complete H8/300 CPU core with 32-bit internal architecture and 16-bit external bus, supporting all instructions documented in the H8/300 Series Programming Manual (ADE-602-025). This ensures binary compatibility with existing H8/300 toolchains and firmware libraries.
What are the key differences between HD6473337YCP16V and HD6433337Y?
HD6473337YCP16V contains 60 KB of reprogrammable ZTAT® flash memory, while HD6433337Y uses mask ROM with fixed firmware. Both share identical CPU, peripherals, pinout, and electrical specs - but HD6433337Y cannot be field-updated and is selected only for high-volume, immutable firmware deployments where flash flexibility is unnecessary.
