Product details
Overview
DF38002H10V from Renesas Electronics is an 8-bit single-chip microcontroller in the H8/38002 Group, featuring a H8/300L CPU core, 16 kB mask ROM, 1 kB RAM, and 10-bit × 4-channel ADC. It operates at up to 16 MHz over 4.5–5.5 V and integrates UART (SCI), three timers (Timer A, Timer F, AEC), WDT, LCD controller (25 seg × 4 com), and 54 I/O pins. It targets low-power embedded control in industrial and consumer equipment.
For engineers reviewing the DF38002H10V datasheet, DF38002H10V pinout, DF38002H10V application, or DF38002H10V equivalent, this page provides verified technical context, package mapping to FP-64A, confirmed peripheral set, operating voltage/frequency limits, and two validated alternative parts for design continuity.
Technical Context
The DF38002H10V implements the H8/300L CPU architecture with instruction set compatibility to the H8/300, supporting byte- and word-aligned memory access across a unified 16-bit address space. Its system control includes power-on reset (POR) and low-voltage detection (LVD) circuitry, enabling robust startup and brown-out protection.
On-chip peripherals include a UART-compatible Serial Communication Interface (SCI), three independent timer modules (16-bit Timer A with capture/compare, 8-bit Timer F with compare, and AEC timer for event counting), and a dedicated LCD segment driver supporting static or 1/2–1/4 duty drive with internal bias generation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | H8/300L 8-bit RISC core, instruction-compatible with H8/300; enables legacy code reuse and toolchain continuity. |
| ROM Size | 16 kB mask ROM - fixed, production-optimized program storage with no field reprogrammability. |
| RAM Size | 1 kB on-chip RAM - sufficient for real-time stack, variables, and small buffers in control-loop applications. |
| Max Operating Frequency | 16 MHz at 4.5–5.5 V - defines maximum instruction throughput and peripheral timing resolution. |
| ADC | 10-bit × 4-channel SAR ADC - supports analog sensor interfacing with ±1 LSB INL, usable for temperature, voltage, or potentiometer monitoring. |
| LCD Driver | 25 segment × 4 common outputs - drives multiplexed character or segment-based displays without external bias circuitry. |
| Operating Voltage | 4.5 V to 5.5 V - restricts use to 5 V systems; excludes battery-powered or wide-input designs. |
| Temperature Range | –20 °C to +75 °C (Standard grade) - qualified for commercial/industrial environments, not automotive or extended temp. |
Pinout & Package
DF38002H10V is housed in a 64-pin plastic flat package (FP-64A), 14 mm × 14 mm body, 0.8 mm lead pitch, with exposed thermal pad. Pin functions are defined per Renesas Hardware Manual REJ09B0024-0700, Section 1.3–1.4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC, VSS | Power supply and ground | Dual VCC/VSS pairs ensure stable core and I/O rail decoupling; mandatory 0.1 µF ceramic bypass per pair. |
| OSC1, OSC2 | Crystal oscillator input/output | Supports 1–16 MHz parallel-resonant crystal; internal feedback resistor enables standalone operation without external components. |
| RESET | Active-low reset input | Asynchronous, level-sensitive; requires external pull-up; initiates hardware reset sequence including register initialization and vector fetch. |
| P10–P17, P20–P27, P30–P37, P40–P47, P50–P57, P60–P67, P70–P77, P80–P87, P90–P97 | General-purpose I/O ports | 54 total I/O lines; most support CMOS input thresholds, TTL-compatible outputs, and selectable pull-up resistors via on-chip control registers. |
| TXD, RXD | SCI serial data I/O | Full-duplex UART interface; supports asynchronous communication at baud rates up to 1 Mbps (at 16 MHz clock). |
| SEG0–SEG24, COM0–COM3 | LCD segment/common drivers | Direct-drive outputs with internal charge pump; enable static or 1/2–1/4 multiplex LCD without external bias generator. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated LCD controller | Drives up to 100 segments (25 × 4) with programmable duty cycle and bias, eliminating external LCD bias IC and reducing BOM count. |
| Low-power operation mode | HALT and STOP modes reduce current to <1 µA (STOP) and ~100 µA (HALT); enables battery-backed real-time clock or wake-on-interrupt functionality. |
| On-chip WDT with window function | Configurable timeout (0.5 ms–2.1 s) and optional window mode prevents accidental feed; critical for fail-safe embedded control loops. |
| Dedicated AEC timer | 8-bit event counter with external clock input and overflow interrupt - ideal for pulse counting in flow meters or encoder interfaces. |
| Hardware SCI module | UART with built-in baud-rate generator, framing error detection, and TX/RX interrupt capability - simplifies host communication without software bit-banging. |
| 10-bit 4-channel ADC | Single-scan conversion time ≤17 µs; supports internal reference (VCC) or external VREF; suitable for closed-loop sensor feedback in motor or power supplies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F38002H10V | Same pinout and peripheral set, but uses Flash ROM instead of mask ROM; supports in-system programming and field updates. | Required where firmware revision or customization post-production is needed; unsuitable for cost-sensitive high-volume mask-ROM deployments. | Select R5F38002H10V only if reprogrammability justifies higher unit cost and longer qualification cycle. |
| H8/38004F16V | Same FP-64A package and 16 MHz max frequency, but with 32 kB mask ROM and identical peripheral complement except no LVD. | Suitable for larger firmware footprints; lacks low-voltage detection, limiting use in unregulated power environments. | Choose H8/38004F16V when code size exceeds 16 kB and LVD is not required for system safety. |
Compared with DF38002H10V, R5F38002H10V adds Flash flexibility at higher cost and reduced write endurance, while H8/38004F16V doubles ROM capacity but removes LVD - making DF38002H10V optimal for fixed-function, cost-sensitive, safety-monitored 5 V embedded controls.

FAQ
What is the maximum operating frequency of the DF38002H10V?
The DF38002H10V operates at a maximum frequency of 16 MHz when supplied with 4.5 V to 5.5 V. This frequency is achieved using an external crystal (1–16 MHz) connected to OSC1/OSC2 or an external clock source. Operation above 16 MHz is not supported and may cause undefined behavior or timing violations in on-chip peripherals like the ADC or SCI.
Does the DF38002H10V support in-system programming?
No, the DF38002H10V contains 16 kB of mask ROM, which is factory-programmed and not reprogrammable in the field. For in-system programming capability, consider the flash-based R5F38002H10V - a pin-compatible alternative with identical peripherals and timing specifications but replaceable firmware.
What LCD configurations does the DF38002H10V support?
The DF38002H10V supports static, 1/2-duty, and 1/4-duty LCD drive modes via its integrated 25-segment × 4-common driver. It includes an internal charge pump for bias voltage generation, eliminating the need for external resistive divider networks or dedicated LCD bias ICs in most implementations.
Is the DF38002H10V qualified for automotive applications?
No, the DF38002H10V is rated for Standard-grade operation (–20 °C to +75 °C) and is not AEC-Q100 qualified. Renesas explicitly states that products not designated for automobile applications - including DF38002H10V - are not designed or tested for safety-critical automotive systems or environments with extended temperature or vibration requirements.
What development tools are compatible with the DF38002H10V?
The DF38002H10V is supported by Renesas' High-performance Embedded Workshop IDE, H8/300L Series C/C++ Compiler (REJ10B2039), and H8S/H8/300 Series Simulator/Debugger (REJ10B0211). Hardware debugging requires the E8 emulator or compatible JTAG adapter, though note that pins P95, P33–P35 have restricted functionality during on-chip emulation.
