Renesas HD64F7047FL25

Overview

HD64F7047FL25 from Renesas Technology Corp. is a 32-bit RISC microcontroller based on the SH-2 CPU core, featuring 256 KB on-chip Flash memory, 100-pin PQFP package, and operation at up to 25 MHz. It integrates on-chip peripherals including interrupt controller (INTC), data transfer controller (DTC), user break controller (UBC), and bus state controller (BSC), targeting embedded control in industrial automation and communication equipment.

For engineers reviewing the HD64F7047FL25 datasheet, HD64F7047FL25 pinout, HD64F7047FL25 application, or HD64F7047FL25 equivalent, key selection criteria include Flash size (256 KB), clock frequency support (25 MHz max), 100-pin PQFP footprint, SH-2 instruction set compatibility, and integrated DTC/INTC for deterministic real-time data movement and interrupt handling.

Technical Context

The HD64F7047FL25 implements the SH-2 architecture with 32-bit general-purpose registers, 16-bit instruction word length, and a five-stage pipeline. It supports multiple operating modes (MCU extension modes 0–2 and single-chip mode) and includes dedicated hardware modules for exception handling, priority-based interrupt management (INTC), and autonomous data transfers (DTC) without CPU intervention.

Its bus interface uses a programmable wait-state controller (BSC) with configurable access timing for external memory and peripherals. The on-chip oscillator supports crystal resonator or external clock input, and the reset subsystem includes power-on and manual reset detection with defined initial register states per SH-2 specification.

Key Specifications

Pinout & Package

HD64F7047FL25 is housed in a 100-pin Plastic Quad Flat Package (PQFP) with 0.65 mm lead pitch, measuring 20 × 14 mm. Pin functions include multiplexed address/data bus (AD0–AD15), control signals (AS#, DS#, WR#, RD#), clock inputs (EXTAL, XTAL), reset (RES#), and dedicated peripheral I/O (e.g., IRQ0–IRQ7, TCLKA–TCLKD, SCKA–SCKD).

FAQ

What is the maximum operating frequency of the HD64F7047FL25?

The HD64F7047FL25 is rated for a maximum clock frequency of 25 MHz. This specification is validated under the recommended operating conditions of 3.3 V ±0.3 V supply voltage and ambient temperature range of –20°C to +75°C. Exceeding 25 MHz may result in undefined behavior or timing violations in internal modules such as the DTC or INTC. The HD64F7047FL25 achieves this speed using the SH-2 core's five-stage pipeline and optimized instruction fetch logic.

Does the HD64F7047FL25 include a CAN controller?

No, the HD64F7047FL25 does not integrate a CAN controller. Its peripheral set includes an interrupt controller (INTC), data transfer controller (DTC), user break controller (UBC), and bus state controller (BSC), but no CAN interface module. CAN functionality is present in later variants such as the HD64F7049F25. For CAN-capable designs using the SH-2 architecture, HD64F7047FL25 requires an external CAN transceiver and software-implemented protocol stack.

What package type and pin count does the HD64F7047FL25 use?

The HD64F7047FL25 uses a 100-pin Plastic Quad Flat Package (PQFP) with 0.65 mm lead pitch and 20 × 14 mm body dimensions. This package supports surface-mount assembly and provides full access to the SH-2 address/data bus (AD0–AD15), control signals (AS#, DS#, WR#, RD#), clock inputs (EXTAL/XTAL), reset (RES#), and 32 interrupt request lines (IRQ0–IRQ7). Pin assignments match the SH7047 Group hardware manual Rev. 2.00.

Is the HD64F7047FL25 pin-compatible with other SH7047 family members?

Yes, the HD64F7047FL25 shares identical pinout and package with other 100-pin SH7047 variants, including the mask-ROM HD6437049 and flash-based HD64F7047Fxx series. All share the same AD0–AD15 bus, IRQx inputs, and BSC control signals. However, differences in on-chip memory size (256 KB vs. 128 KB), peripheral inclusion (e.g., CAN), and electrical characteristics (e.g., max frequency) require verification before direct substitution.

What development tools support the HD64F7047FL25?

The HD64F7047FL25 is supported by Renesas' legacy SuperH toolchain, including the SuperH RISC engine C/C++ Compiler (ADE-702-372), Simulator/Debugger (ADE-702-186), and High-performance Embedded Workshop IDE (ADE-702-201). These tools target the SH-2 instruction set and provide register-level debugging, DTC configuration, and INTC priority mapping. Third-party JTAG emulators compliant with SH-2 debug architecture are also compatible.
