Renesas HD6473308RF10V

Overview

HD6473308RF10V from Renesas Technology Corp. is a single-chip 16-bit microcontroller based on the H8/300 CPU core, featuring 16 KB on-chip ROM, 512 bytes RAM, 15-byte dual-port RAM, 10-bit A/D converter, serial I/O, and multiple timer modules including 16-bit free-running, 8-bit, and PWM timers. It targets embedded industrial control systems requiring deterministic real-time response.

For engineers reviewing the HD6473308RF10V datasheet, HD6473308RF10V pinout, HD6473308RF10V application, or HD6473308RF10V equivalent, key selection criteria include on-chip memory configuration (ROM type: mask-programmable), operating voltage (4.5–5.5 V), maximum clock frequency (10 MHz), and integrated peripheral set for sensor interfacing and motor timing control.

Technical Context

The HD6473308RF10V implements the H8/300 instruction set architecture with 16-bit data bus and 24-bit address space, supporting single-chip mode operation without external memory expansion. Its memory map includes dedicated register fields at fixed addresses (e.g., TIER at H'FF90, ADCSR at H'FFE8) and peripheral control registers mapped into I/O space.

It integrates three independent timer subsystems: a 16-bit free-running timer with input capture and output compare, two 8-bit timers with external reset capability, and two PWM timers with programmable duty cycle via DTR registers. The A/D converter supports both single and scan modes across up to 8 analog inputs with configurable sampling time.

Key Specifications

Pinout & Package

HD6473308RF10V is housed in a 64-pin plastic QFP (Quad Flat Package) with 0.5 mm lead pitch. Pin functions are defined per the H8/330 hardware manual Section 1.3, including multiplexed I/O ports (P1–P9), dedicated A/D input pins (AN0–AN7), serial interface signals (TXD/RXD), timer I/O (TO0–TO3, TI0–TI3), and system control lines (RESET, XIN/XOUT, MODE).

The H8/330 family-including HD6473308RF10V-was designed for deterministic real-time embedded control in resource-constrained industrial equipment, emphasizing on-chip integration, low-power operation, and robust peripheral sets for sensor and actuator interfacing.

FAQ

What is the ROM type used in HD6473308RF10V?

The HD6473308RF10V uses mask-programmable ROM. This means the firmware is permanently embedded during wafer fabrication and cannot be modified after packaging. It is optimized for high-volume production where firmware stability and cost efficiency are critical. HD6473308RF10V does not support in-system programming or field updates.

Does HD6473308RF10V support external memory expansion?

No, HD6473308RF10V operates exclusively in single-chip mode and lacks external bus interface signals such as address/data buses or chip select outputs. All program execution and data storage occur within its on-chip 16 KB ROM and 512-byte RAM. HD6473308RF10V is intended for self-contained embedded applications without external memory requirements.

What are the power management capabilities of HD6473308RF10V?

HD6473308RF10V supports three low-power states: Sleep Mode (CPU halted, peripherals active), Software Standby Mode (clock stopped, RAM retained), and Hardware Standby Mode (all clocks stopped, minimal current draw). These modes are controlled via the System Control Register (SYSCR) and enable sub-10 µA standby current. HD6473308RF10V can wake from any mode via external interrupt or reset.

Can HD6473308RF10V perform simultaneous A/D conversions on multiple channels?

No, HD6473308RF10V performs sequential A/D conversions-even in scan mode-using a single sample-and-hold circuit and successive approximation register. Up to eight channels (AN0–AN7) can be scanned in software-defined order, but only one conversion completes at a time. HD6473308RF10V does not support true simultaneous sampling or multi-channel parallel conversion.

Is HD6473308RF10V pin-compatible with other H8/330 family members?

Yes, HD6473308RF10V shares the same 64-pin QFP package and pin assignment with HD64F3308FV and HD6433308FV, as confirmed in the H8/330 Hardware Manual Section 1.3.1. Signal names, electrical characteristics, and peripheral mappings are identical across these variants, enabling drop-in replacement where ROM type and temperature grade align.
