Product details
Overview
DF38004FP10V 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, and operation at up to 16 MHz over 4.5–5.5 V. It integrates 10-bit × 4-channel ADC, UART (SCI), LCD controller (25 seg × 4 com), WDT, and 39 I/O pins - deployed in industrial control panels requiring low-power, integrated timing and display management.
For engineers reviewing the DF38004FP10V datasheet, DF38004FP10V pinout, DF38004FP10V application, or DF38004FP10V equivalent, this page delivers verified package mapping (FP-64A), confirmed peripheral register layout, real-world use context for SCI-based sensor interfacing, and validated alternative options for legacy H8/300L migration paths.
Technical Context
The DF38004FP10V implements the H8/300L CPU architecture with full instruction set compatibility to the H8/300, supporting 16-bit addressing and 8-bit data processing. Its on-chip peripherals include a single-channel UART (SCI) with clock-synchronous and asynchronous modes, a 10-bit successive-approximation ADC with four analog inputs, and a dedicated LCD segment driver supporting static or 1/2–1/4 duty drive.
System-level features include power-on reset (POR), low-voltage detection (LVD), and an on-chip watchdog timer (WDT). The device operates across –20°C to +75°C (standard grade) and supports external crystal, ceramic resonator, or internal RC oscillator configurations via OSC1/OSC2 pins - with reset release synchronized to stable clock acquisition.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | H8/300L 8-bit RISC core, instruction-compatible with H8/300; enables reuse of legacy toolchains and firmware libraries. |
| ROM Size | 16 KB mask ROM - fixed, factory-programmed code storage; eliminates external boot ROM and reduces BOM cost. |
| RAM Size | 1 KB on-chip RAM - sufficient for stack, variables, and small buffers in embedded control applications without external memory. |
| Max Operating Frequency | 16 MHz at 4.5–5.5 V - defines real-time response limit for control loops and serial communication timing budgets. |
| ADC Resolution & Channels | 10-bit × 4-channel SAR ADC - supports precision analog sensing (e.g., temperature, voltage monitoring) with hardware-triggered conversion. |
| LCD Driver | 25 segment × 4 common outputs - drives alphanumeric LCDs directly without external bias circuitry or glass-specific drivers. |
| SCI Interface | 1-channel UART with programmable baud rate generator - enables RS-232/RS-485 communication using standard framing and interrupt-driven TX/RX. |
| Operating Temperature | –20°C to +75°C (Standard grade) - qualified for commercial/industrial environments excluding automotive or safety-critical systems. |
Pinout & Package
DF38004FP10V is housed in a 64-pin plastic QFP package designated FP-64A (14 mm × 14 mm, 0.8 mm pitch), compliant with JEDEC MS-026. Pin assignments follow Renesas' standardized H8/38004 Group layout with dedicated ports P0–P9, OSC1/OSC2, RESET, VSS/VDD, and LCD segment/common outputs.

FAQ
What is the package type and pin count of DF38004FP10V?
The DF38004FP10V uses a 64-pin FP-64A plastic QFP package (14 mm × 14 mm, 0.8 mm pitch) with standard JEDEC MS-026 footprint. All 64 pins are assigned per Renesas' H8/38004 Group pinout specification, including dedicated LCD segment/common drivers, ADC inputs, and SCI interface signals. This package enables high I/O density while maintaining compatibility with standard reflow soldering processes.
Does DF38004FP10V include an internal oscillator or require an external crystal?
The DF38004FP10V supports both external and internal clock sources. It includes an on-chip RC oscillator usable for basic timing, but full specification compliance - especially for UART baud rate accuracy and ADC sampling consistency - requires an external crystal or ceramic resonator connected between OSC1 and OSC2 pins. Renesas specifies 1–16 MHz parallel-resonant crystals for stable operation at 16 MHz.
Can DF38004FP10V drive an LCD without external bias circuitry?
Yes, DF38004FP10V integrates a full LCD controller supporting up to 25 segments and 4 commons, with programmable bias voltage generation and waveform timing. It directly drives static, 1/2-duty, or 1/4-duty LCD glass without external resistors, capacitors, or dedicated bias ICs - reducing bill-of-materials and simplifying layout for display-centric applications like control panels and meters.
What is the memory configuration of DF38004FP10V?
The DF38004FP10V contains 16 KB of mask-programmed ROM for firmware storage and 1 KB of on-chip RAM for runtime variables and stack operations. The mask ROM is factory-programmed and immutable, ensuring firmware integrity and eliminating boot-time flash programming risks. This configuration targets cost-sensitive, high-volume applications where firmware is finalized before production.
Is DF38004FP10V qualified for automotive applications?
No, DF38004FP10V is rated for Standard-grade operation (–20°C to +75°C) and is not qualified to AEC-Q100 or automotive reliability standards. Renesas explicitly designates it for computers, office equipment, industrial robots, and home appliances - not transportation systems or safety-critical functions. For automotive use, engineers must select Renesas' designated High Quality or automotive-specific MCU families.
