Product details
Overview
DF38076RW10V from Renesas Electronics is a 16-bit single-chip microcomputer in the H8/38076R Group, featuring the H8/300H CPU core, 52 KB on-chip ROM, 4 KB RAM, and integrated peripherals including 16-bit timer pulse unit (TPU), serial communication interfaces (SCI), and real-time clock (RTC). It operates at up to 20 MHz, supports multiple low-power modes (subactive, subsleep, standby), and targets embedded control applications requiring deterministic timing and flash-based firmware execution.
For engineers reviewing the DF38076RW10V datasheet, DF38076RW10V pinout, DF38076RW10V application, or DF38076RW10V equivalent, key selection criteria include its TQFP-80 package, 3.3 V operation, on-chip debugging support via dedicated pins (P16, P36, P37 reserved), and compatibility with Renesas' H8/300H software toolchain and E7 emulator.
Technical Context
The DF38076RW10V implements the H8/300H CPU architecture with full instruction set compatibility to the H8/300, enabling legacy code reuse. Its memory map includes 52 KB of on-chip ROM (flash version), 4 KB RAM, and dedicated vector tables for 25 internal interrupts plus external IRQ/NMI inputs.
Power management is handled by dual clock generators: a main system oscillator (up to 20 MHz) and a subclock generator supporting 32.768 kHz or 38.4 kHz crystal resonators for RTC operation. Mode transitions - active, subactive, subsleep, and standby - are controlled via SYSCR1/SYSCR2 registers and enforced by hardware state logic without software polling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | H8/300H 16-bit RISC core, instruction-compatible with H8/300; enables migration of legacy firmware and toolchain reuse. |
| Memory | 52 KB on-chip ROM (flash), 4 KB RAM; eliminates need for external program memory in cost-sensitive embedded designs. |
| Max Clock Frequency | 20 MHz system clock; supports real-time control loops with sub-50 ns instruction cycle time (e.g., 200 ns for MOV.W). |
| Operating Voltage | 3.0 V to 3.6 V; compatible with standard 3.3 V industrial power rails and LDO regulators. |
| Low-Power Modes | Subactive, subsleep, and standby modes with RTC retention; enables battery-backed operation with µA-level current draw. |
| Interrupt Support | 25 internal + 8 external interrupt sources; priority managed via IPRA–IPRE registers and INTM mask bits for nested handling. |
| Package | TQFP-80 (12 × 12 mm, 0.5 mm pitch); surface-mount compatible with automated PCB assembly and thermal relief design. |
Pinout & Package
TQFP-80 package (PTQP0080KC-A), 12 × 12 mm body, 0.5 mm lead pitch, exposed pad not electrically connected. Pin functions validated per Renesas Hardware Manual Rev.4.00 (2006), Table 1.4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC, VSS | Power supply and ground | Dedicated pairs for analog/digital separation; decoupling required within 10 mm of each VCC/VSS pair. |
| OSC1, OSC2 | Main system oscillator input/output | Connects to 4.19 MHz crystal (e.g., Kyocera HC-491U-S); internal feedback resistor enabled; no external load caps needed. |
| XT1, XT2 | Subclock oscillator input/output | Supports 32.768 kHz or 38.4 kHz crystal (e.g., Epson C-001R); RS ≤ 35 kΩ required for reliable startup in low-power mode. |
| P16, P36, P37 | On-chip debugging interface | Reserved for E7 emulator use; unavailable as general-purpose I/O unless external debug hardware bypass is implemented. |
| NMI | Non-maskable interrupt input | Active-low, edge-triggered; cannot be disabled by software; used for critical fault recovery or watchdog timeout. |
| RES | Reset input | Active-low; internal POR circuit adjustable via external capacitor; ensures reset assertion until oscillator stabilizes (≥10 ms typical). |
Key Features
| Feature | Design Value |
|---|---|
| On-chip debugging support | Dedicated E7 emulator interface with hardware breakpoints and real-time trace; eliminates need for external JTAG adapter in development. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F38076W10V | Same H8/38076R silicon; Renesas rebranded part number post-2010 merger; identical electrical specs, pinout, and firmware binary compatibility. | No functional difference; used interchangeably in new designs where Renesas branding is preferred. | Select R5F38076W10V for new BOMs to ensure long-term documentation alignment with current Renesas naming conventions. |
| H8/38075R | Pin-compatible variant with 36 KB ROM, 2 KB RAM, and reduced peripheral set (no SCI4, fewer TPU channels); same TQFP-80 package and voltage range. | Suitable for cost-optimized designs with lower memory and I/O requirements; not drop-in for applications needing full 52 KB or four SCIs. | Choose H8/38075R only if firmware fits in 36 KB and SCI4/TPU channel count is non-critical; verify register map differences in SYSCR and CKSTPR. |
Compared with DF38076RW10V, R5F38076W10V offers identical functionality under updated branding, while H8/38075R trades memory and peripheral capacity for lower unit cost - making it viable only when application constraints allow reduction in both code size and I/O count.

FAQ
What is the maximum operating frequency of the DF38076RW10V?
The DF38076RW10V supports a maximum system clock frequency of 20 MHz. This is achieved using the main oscillator (OSC1/OSC2) with an external 4.19 MHz crystal and internal PLL multiplication, enabling instruction execution at 50 ns per cycle in active mode. The device maintains full functionality across its specified 3.0–3.6 V supply range at this speed.
Does the DF38076RW10V support in-circuit debugging?
Yes, the DF38076RW10V supports hardware-assisted in-circuit debugging via Renesas' E7 emulator. Pins P16, P36, and P37 are dedicated to this interface and must remain unconnected to user circuitry during debug sessions. When enabled, the on-chip debugging module provides real-time trace, address breakpoints, and register visibility without requiring external debug probes.
Can the DF38076RW10V retain RTC time during power-down?
Yes, the DF38076RW10V retains RTC timekeeping in subsleep and standby modes using the 32.768 kHz subclock oscillator. The RTC continues operating with typical current draw of 1.2 µA, provided XT1/XT2 are connected to a compliant crystal (e.g., Epson C-001R, RS ≤ 35 kΩ) and backup power is maintained on VCC.
What package type is used for the DF38076RW10V?
The DF38076RW10V is packaged in a TQFP-80 (Thin Quad Flat Package) with 80 leads, 12 × 12 mm body size, and 0.5 mm lead pitch (part code PTQP0080KC-A). This RoHS-compliant package supports standard reflow soldering and provides adequate thermal dissipation for continuous operation at 20 MHz.
Is the DF38076RW10V pin-compatible with other H8/38076R variants?
Yes, the DF38076RW10V shares identical pinout and package with all members of the H8/38076R Group, including H8/38075R and H8/38074R. However, peripheral enablement (e.g., SCI4, TPU channels) and memory size differ between variants - requiring firmware validation even when hardware layout is reused.
