Product details
Overview
DF38004FP10WV from Renesas Electronics is an 8-bit single-chip microcontroller in the H8/38004 Group, featuring a H8/300L CPU core, 16 kB mask ROM, 1 kB RAM, 10-bit × 4-channel ADC, and integrated LCD controller (25 seg × 4 com). It operates at up to 16 MHz over 4.5–5.5 V and targets low-power embedded control in industrial and consumer applications.
For engineers reviewing the DF38004FP10WV datasheet, DF38004FP10WV pinout, DF38004FP10WV application, or DF38004FP10WV equivalent, key selection considerations include its FP-64A package, on-chip WDT and LVD, SCI UART interface, and support for external interrupt wakeup with 11 sources - critical for battery-powered instrumentation and appliance control designs.
Technical Context
The DF38004FP10WV implements the H8/300L CPU architecture with instruction set compatibility to the H8/300, enabling legacy code reuse. It integrates system-control modules including power-on reset (POR), low-voltage detection (LVD), and watchdog timer (WDT) with discrete configuration.
Peripheral integration includes one 16-bit clock timer (Timer A), one 16-bit compare timer (Timer F), one AEC timer, one UART-compatible SCI channel, and a 10-bit ADC with four analog inputs - all mapped to dedicated I/O pins with configurable pull-up/pull-down and wake-up capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | H8/300L 8-bit RISC core, instruction-compatible with H8/300 for migration-ready firmware development |
| ROM/Flash | 16 kB mask ROM - fixed, production-optimized program storage with no field reprogramming |
| RAM | 1 kB on-chip SRAM - sufficient for real-time control stacks, ISR context, and small data buffers |
| ADC | 10-bit × 4-channel SAR ADC - supports sensor interfacing (e.g., temperature, voltage monitoring) with internal reference |
| Operating Voltage | 4.5 V to 5.5 V - suited for stable 5 V rail systems; not rated for low-voltage operation below 4.5 V |
| Max Clock Frequency | 16 MHz - enables deterministic real-time response with ≤62.5 ns instruction cycle time (single-cycle instructions) |
| Package | FP-64A - 64-pin plastic QFP, 14 mm × 14 mm, 0.8 mm pitch; compatible with standard surface-mount assembly |
| Temperature Range | –20 °C to +75 °C (Standard grade) - qualified for commercial/industrial ambient environments |
Pinout & Package
DF38004FP10WV is housed in the FP-64A package: 64-pin plastic quad flat pack with 0.8 mm lead pitch, 14 mm × 14 mm body size, and exposed thermal pad (non-electrical). Pin numbering follows standard counter-clockwise convention from pin 1 (top-left corner, marked dot).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC, VSS | Power supply and ground | Dedicated pairs for digital core (VCC1/VSS1) and I/O (VCC2/VSS2) - require separate decoupling for noise immunity |
| OSC1, OSC2 | Crystal oscillator input/output | Supports external quartz crystal (1–16 MHz) or ceramic resonator; internal oscillator not available in this variant |
| RESET | Active-low reset input | Asynchronous, level-sensitive reset; internal pull-up ensures defined state during power-up without external resistor |
| P10–P17, P20–P27, P30–P37, P40–P47, P50–P57, P60–P67, P70–P77, P80–P87, P90–P97 | Bi-directional CMOS I/O ports | Configurable per-port direction register; most support external interrupt, pull-up, and wake-up - 39 total usable I/O lines |
| AD0–AD3 | Analog input channels | Dedicated pins for 10-bit ADC; share functions with P10–P13 but require analog mode enable and input buffer activation |
| SCI_TXD, SCI_RXD | UART serial interface | Full-duplex asynchronous communication; supports baud rates up to 1 Mbps at 16 MHz clock (with appropriate divisor) |
Key Features
| Feature | Design Value |
|---|---|
| On-chip WDT with discrete configuration | Independent watchdog timer with selectable timeout periods - prevents software lockup without relying on CPU clock domain |
| Low-voltage detection (LVD) | Monitors VCC and triggers interrupt or reset at programmable threshold (4.2 V typical) - safeguards against brown-out corruption |
| LCD controller (25 seg × 4 com) | Direct drive for multiplexed segment-combination LCDs - eliminates external driver IC in display-enabled appliances |
| 11 external interrupt sources with wake-up | Enables ultra-low-power sleep modes (e.g., STOP mode) with fast (<10 µs) wake-up via edge-triggered GPIO events |
| SCI UART with clock-synchronous mode | Supports both asynchronous UART and synchronous clocked serial - simplifies interface to sensors, displays, or host controllers |
| Power-on reset (POR) | Guarantees known initial state at power ramp; eliminates need for external reset IC in cost-sensitive designs |

FAQ
What is the maximum operating frequency of the DF38004FP10WV?
The DF38004FP10WV supports a maximum operating frequency of 16 MHz when powered within its specified 4.5 V to 5.5 V supply range. This frequency is achieved using an external crystal or resonator connected to OSC1/OSC2 pins. Operation above 16 MHz is not supported, and timing parameters in the hardware manual are validated only up to this limit.
Does the DF38004FP10WV include on-chip debug capability?
Yes, the DF38004FP10WV includes an on-chip emulator (OCE) supporting debugging via dedicated pins (P95, P33–P35), though these pins are unavailable for general I/O when OCE is active. Debug access requires Renesas E8 or E10 emulator hardware and compatible IDE tools such as High-performance Embedded Workshop.
Is the DF38004FP10WV pin-compatible with other H8/38004 Group members?
Yes, the DF38004FP10WV uses the FP-64A package and shares identical pin assignment and electrical characteristics with all other H8/38004 Group variants in the same package option, including DF38004FP10WV, DF38004FP10WV, and mask-ROM equivalents - enabling direct substitution where memory and temperature grade requirements align.
What ADC resolution and channel count does the DF38004FP10WV provide?
The DF38004FP10WV integrates a 10-bit successive approximation register (SAR) ADC with four input channels (AD0–AD3). Each channel maps to dedicated pins P10–P13 and supports programmable sampling time, internal reference voltage, and conversion trigger via software or timer event - delivering ±2 LSB integral nonlinearity across the full operating range.
What is the qualified operating temperature range for the DF38004FP10WV?
The DF38004FP10WV is qualified for the Standard temperature grade: –20 °C to +75 °C ambient. This rating applies to commercial and industrial indoor applications. It is not qualified for extended temperature ranges (e.g., –40 °C to +85 °C) unless explicitly marked with the "WTR" suffix, which DF38004FP10WV does not carry.
