Renesas HD64F3067RVX13

Overview

HD64F3067RVX13 from Renesas Technology Corp. is a 16-bit Flash-based microcontroller featuring the H8/300H CPU core, 256 KB on-chip flash memory, 16 KB RAM, and integrated peripherals including three-channel SCI (with ISO/IEC7816-3 smart card support), 16-bit timers, A/D and D/A converters, DMA controller, and programmable timing pattern controller. It operates at up to 20 MHz and supports seven configurable MCU operating modes for flexible memory interface design.

For engineers reviewing the HD64F3067RVX13 datasheet, HD64F3067RVX13 pinout, HD64F3067RVX13 application, or HD64F3067RVX13 equivalent, key selection criteria include flash programmability in-system, multi-mode bus configuration (8/16-bit data width, selectable address space), smart card interface compliance, and low-power standby capability with module-level clock gating.

Technical Context

The HD64F3067RVX13 implements the H8/300H 32-bit internal architecture with sixteen 16-bit general-purpose registers and a linear 16-Mbyte address space. Its bus controller supports eight independent memory areas with per-area data bus width (8/16-bit) and access cycle control via ABWCR and ASTCR registers.

It integrates a programmable timing pattern controller (TPC) for motor control waveforms, a watchdog timer (WDT), and a system control register (SYSCR) enabling software-selectable standby timer and clock division. The SCI module supports asynchronous, clock-synchronous, and ISO/IEC7816-3 smart card protocols with automatic guard time and character timing control.

FAQ

What is the maximum system clock frequency supported by the HD64F3067RVX13?

The HD64F3067RVX13 supports a maximum system clock frequency of 20 MHz. This rating is validated across commercial temperature range (0°C to +70°C) and 4.5 V to 5.5 V supply voltage. Operation above 20 MHz may cause timing violations in the A/D converter, SCI baud generation, and bus interface logic. For designs requiring higher throughput, Renesas recommends evaluating the H8SX-based R5F3366EDFP as a migration path.

Does the HD64F3067RVX13 include an integrated D/A converter?

Yes, the HD64F3067RVX13 includes a single 8-bit D/A converter with voltage output. It is implemented as a resistor-string DAC referenced to AVCC, providing monotonic output with ±1 LSB integral nonlinearity. The DAC output is accessible on pin DA0 and is commonly used for analog setpoint generation in motor control and calibration circuits within the HD64F3067RVX13-based system.

Is the HD64F3067RVX13 pin-compatible with other members of the H8/3067 series?

Yes, the HD64F3067RVX13 shares the same 120-pin QFP package and pinout with mask ROM versions (e.g., HD6433067F) and other Flash variants (e.g., HD64F3067FV) in the H8/3067 family. Pin functions-including I/O mapping, bus signals, and peripheral assignments-are identical across these variants in all seven operating modes, enabling direct substitution where flash programmability is required.

What documentation is required to develop firmware for the HD64F3067RVX13?

To develop firmware for the HD64F3067RVX13, engineers require the Hardware Manual ADE-602-135B (Rev. 3.0) for register-level peripheral configuration and the H8/300H Series Programming Manual for instruction set details. Renesas also provides the HEW (High-performance Embedded Workshop) IDE and associated F-ZTAT™ programming utilities, which support in-circuit debugging and flash programming via the on-chip JTAG interface of the HD64F3067RVX13.

How does the HD64F3067RVX13 handle power management in battery-operated applications?

The HD64F3067RVX13 supports multiple low-power states: software standby mode (CPU halted, RAM retained, selected peripherals clocked), module standby (individual peripheral clocks gated via SYSCR), and deep stop mode (all clocks stopped except RTC). Current consumption drops to <1 mA in software standby and <10 µA in deep stop, with wake-up possible via external interrupt or internal timer-making the HD64F3067RVX13 suitable for long-life battery applications such as portable medical devices.
