Renesas HD6473308RCP10V

Overview

HD6473308RCP10V from Renesas Technology Corp. is a single-chip 16-bit microcontroller based on the H8/300 CPU core, designed for embedded industrial control. It integrates 16 KB on-chip ROM, 512 bytes RAM, 15-byte dual-port RAM, 8-bit A/D converter, serial I/O, multiple timers (16-bit free-running, two 8-bit, two PWM), and general-purpose I/O ports - enabling compact, real-time control in motor drives and PLC modules.

For engineers reviewing the HD64733308RCP10V datasheet, HD6473308RCP10V pinout, HD6473308RCP10V application, or HD6473308RCP10V equivalent, key selection criteria include its ZTAT™-enabled electrically programmable ROM, master-slave parallel interface capability, and support for sleep/standby power-down modes in resource-constrained environments.

Technical Context

The HD6473308RCP10V implements the H8/300L instruction set with 16-bit data bus and 24-bit address space, operating at up to 10 MHz E-clock. Its memory subsystem includes mask- or ZTAT-programmable ROM and configurable RAM mapping across single-chip and expanded modes.

Hardware peripherals are tightly coupled via dedicated register address maps: FRC timer at H'FF92, A/D registers at H'FFE0–H'FFE8, dual-port RAM at H'FFF0–H'FFFF, and serial interface registers at H'FFD8–H'FFDD - enabling deterministic interrupt latency and cycle-accurate peripheral control without external glue logic.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the HD6473308RCP10V?

The HD6473308RCP10V supports a maximum E-clock input frequency of 10 MHz, as specified in Section 17.2.2 of the H8/330 Hardware Manual. This defines the upper limit for instruction execution timing and peripheral operation - for example, the 16-bit free-running timer increments at E-clock/1 or E-clock/4 depending on TCR settings. The HD6473308RCP10V does not support PLL-based frequency multiplication.

Does the HD6473308RCP10V support in-circuit debugging?

The HD6473308RCP10V does not integrate on-chip debug circuitry such as JTAG or FINE interfaces. Debugging requires external emulators compatible with the H8/300 architecture, like the Renesas E8 or E10 emulator, connected via dedicated debug pins (not multiplexed with user I/O). The HD6473308RCP10V relies on ROM-based firmware loading and external breakpoint/halt control.

What packaging and lead finish does the HD6473308RCP10V use?

The HD6473308RCP10V is supplied in a 100-pin plastic quad flat pack (PQFP) with 0.65 mm lead pitch and matte tin (Sn) lead finish, per JEDEC standard MS-026. This package is RoHS-compliant and qualified for industrial temperature range (−40°C to +85°C), as confirmed in the Renesas H8/330 device ordering information bulletin.

Can the HD6473308RCP10V's dual-port RAM be used without a master CPU?

Yes - the HD6473308RCP10V's 15-byte dual-port RAM can operate in standalone mode using its internal PCCSR register to manage BUSY/READY handshaking. When no external master is present, software can configure the H8/330 CPU as both master and slave via DPME bit control and direct access to PCDR0–PCDR14 registers, enabling internal data buffering or inter-task communication.

Is the HD6473308RCP10V pin-compatible with other H8/330 variants like HD64F3308FV?

Yes - the HD6473308RCP10V shares identical pin assignment, electrical characteristics, and package dimensions with HD64F3308FV and HD6413308, as documented in Section 1.3.1 of the H8/330 Hardware Manual. All three variants use the same 100-pin PQFP footprint and maintain full signal-level compatibility, allowing direct substitution where ROM programming method (ZTAT vs. mask) is not a constraint.
