Overview
DF38602RFT10WV from Renesas Electronics is a 16-bit single-chip microcomputer in the H8/300H Super Low Power Series, featuring an H8/300H CPU core with H8/300 instruction set compatibility, 128 KB on-chip ROM, 8 KB RAM, and integrated peripherals including 3-channel UART (SCI), 16-bit timer/counters, and 8-channel 10-bit ADC. It operates at up to 20 MHz with supply voltage of 2.7–5.5 V and targets battery-powered industrial control and sensor interface applications.
For engineers reviewing the DF38602RFT10WV datasheet, DF38602RFT10WV pinout, DF38602RFT10WV application, or DF38602RFT10WV equivalent, this page provides verified technical context, package mapping, functional specifications, real-world use cases, and validated alternative options for embedded system design and BOM optimization.
Technical Context
The DF38602RFT10WV implements a Harvard-architecture H8/300H CPU with 24-bit address space, supporting both internal ROM execution and external memory expansion via multiplexed address/data bus. Its clock system includes dual oscillators - main system clock (up to 20 MHz) and subclock (32.768 kHz) - with programmable prescalers (S and W) enabling flexible low-power timing modes including stop, sleep, and wait states.
Peripheral integration includes three independent serial communication interfaces (SCI0–SCI2) with selectable baud rates and framing, eight 10-bit ADC input channels with software/hardware trigger support, and four 16-bit timer modules (TMR0–TMR3) offering input capture, output compare, PWM generation, and interval timing functions - all accessible via memory-mapped registers with interrupt capability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F38602DNEFP | Same H8/38602R core, but uses flash memory (128 KB) instead of mask ROM; supports in-field firmware updates. | Preferred for prototyping or products requiring post-deployment bug fixes; requires external programming infrastructure. | Select R5F38602DNEFP when firmware agility outweighs cost and security benefits of mask ROM. |
| H8/3687F | Earlier H8/300H variant with 64 KB ROM, no subclock oscillator, and only two SCI channels. | Suitable for simpler control tasks without RTC or multi-interface requirements; lacks Stop mode subclock retention. | Choose H8/3687F only if existing design constraints mandate pin compatibility and reduced feature set. |
Compared with DF38602RFT10WV, R5F38602DNEFP offers field-upgradable firmware at higher unit cost and slightly lower security, while H8/3687F sacrifices subclock-based low-power timing and one SCI channel - making DF38602RFT10WV optimal for battery-operated, multi-interface sensor edge nodes requiring long-term firmware stability.

FAQ
What is the maximum operating frequency of the DF38602RFT10WV?
The DF38602RFT10WV supports a maximum system clock frequency of 20 MHz, delivering approximately 12.5 million instructions per second (MIPS). This frequency is achieved using the on-chip oscillator with an external crystal resonator connected to OSC1/OSC2 pins, and it defines the upper limit for real-time processing throughput in applications such as motor control or high-speed data acquisition. DF38602RFT10WV maintains full functionality across its specified voltage range (2.7–5.5 V) at this speed.
Does the DF38602RFT10WV include on-chip memory for program storage?
Yes, the DF38602RFT10WV integrates 128 KB of on-chip mask ROM for program storage, eliminating the need for external nonvolatile memory. This ROM is programmed during manufacturing and provides immutable, tamper-resistant firmware execution - ideal for high-volume, fixed-function applications like industrial controllers or sensor transmitters. DF38602RFT10WV also includes 8 KB of on-chip RAM for runtime variables, stack, and data buffering.
How many serial communication interfaces does the DF38602RFT10WV support?
The DF38602RFT10WV supports three independent serial communication interfaces (SCI0, SCI1, and SCI2), each configurable as UART with programmable baud rates, parity, and stop bits. These interfaces operate concurrently and can be assigned to different port pins, enabling simultaneous communication with multiple peripherals - for example, SCI0 for sensor telemetry, SCI1 for host diagnostics, and SCI2 for network bridging. DF38602RFT10WV's SCI modules do not share resources, ensuring deterministic latency.
What analog-to-digital conversion capability does the DF38602RFT10WV provide?
The DF38602RFT10WV features an 8-channel, 10-bit successive approximation register (SAR) ADC with built-in sample-and-hold. Conversion can be triggered by software, timer events, or external signals, and results are stored in dedicated data registers accessible via memory-mapped I/O. This ADC supports input ranges matching the device's VCC supply (0–VCC), making DF38602RFT10WV suitable for direct interfacing with resistive sensors, voltage dividers, and current-sense amplifiers without external signal conditioning.
Is the DF38602RFT10WV suitable for low-power battery-operated applications?
Yes, the DF38602RFT10WV is explicitly designed for low-power operation, featuring Stop, Sleep, and Wait modes with subclock (32.768 kHz) retention. In Stop mode, current consumption drops below 1 µA while preserving RAM contents and allowing wake-up via external interrupt or subclock alarm - ideal for periodic sensor reading in battery-powered data loggers. DF38602RFT10WV's 2.7–5.5 V supply range further enhances compatibility with single-cell Li-ion or alkaline battery configurations.
