Product details
Overview
DF36024FXV from Renesas Electronics is a 16-bit single-chip microcomputer in the H8/36024 Group, featuring the H8/300H CPU core with instruction compatibility to the H8/300. It integrates on-chip ROM (256 KB), RAM (16 KB), and peripherals including SCI, I2C, timers, and A/D converter. Operates at up to 20 MHz with 3.3 V supply, targeting embedded control in industrial instrumentation and motor drive systems.
For engineers reviewing the DF36024FXV datasheet, DF36024FXV pinout, DF36024FXV application, or DF36024FXV equivalent, key selection considerations include its 100-pin LQFP package, 256 KB flash memory with on-board programming support, 10-bit 8-channel ADC, and integrated clock pulse generator with crystal/ceramic resonator interface.
Technical Context
The DF36024FXV implements the H8/300H CPU architecture with 24-bit address space, supporting both little-endian and big-endian data access modes. Its memory map includes dedicated areas for on-chip ROM (0x000000–0x03FFFF), RAM (0xFFE000–0xFFFFFF), and peripheral registers (0xF00000–0xF00FFF).
Peripheral integration includes three serial communication interfaces (SCI0–SCI2), one I2C bus interface, eight 16-bit timer channels (with input capture/output compare), and an 8-channel 10-bit successive-approximation ADC with sample-and-hold. Power management supports Sleep, Standby, and Subsleep modes controlled via SYSCR1/SYSCR2 registers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | H8/300H 16-bit RISC core, instruction-compatible with H8/300; enables legacy code reuse and toolchain continuity. |
| Max Operating Frequency | 20 MHz at 3.3 V; defines real-time response capability for closed-loop motor control and sensor sampling. |
| On-Chip Memory | 256 KB flash ROM + 16 KB SRAM; sufficient for standalone firmware with bootloader, communication stack, and control algorithms. |
| Analog-to-Digital Converter | 10-bit resolution, 8-channel SAR ADC with internal sample-and-hold; supports simultaneous sampling of multiple analog sensors. |
| Serial Interfaces | 3 × SCI (UART-like), 1 × I2C; enables multi-protocol connectivity to displays, EEPROMs, and host controllers without external transceivers. |
| Package | 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch); compatible with standard SMT assembly and provides full peripheral pin access. |
| Power Supply | Single 3.3 V ±0.3 V supply; simplifies power design by eliminating need for dual-rail regulators or level shifters. |
Pinout & Package
DF36024FXV is housed in a 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are defined per Hardware Manual Rev. 4.00 (2005), Section 1.3–1.4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC, VSS | Power supply and ground | Dedicated pairs for digital core (VCC1/VSS1) and I/O (VCC2/VSS2); mandatory decoupling required per pin group to suppress switching noise. |
| XTAL/EXTAL | Clock input/output | Connects to 1–20 MHz crystal or ceramic resonator; configures system clock source via on-chip oscillator circuit. |
| RESET | Active-low reset input | Asynchronous reset assertion clears CPU state, resets peripherals, and forces boot vector fetch; requires external pull-up. |
| P00–P07 | Port 0 bidirectional I/O | Configurable as general-purpose I/O or alternate functions (e.g., SCI0 TX/RX, timer inputs); supports CMOS-level drive strength. |
| AD0–AD7 | Analog input channels | Direct connection to 10-bit ADC inputs; require external RC filtering and guard traces to maintain SNR > 58 dB. |
| CLKOUT | System clock output | Provides buffered copy of internal φ-clock (1/2 or 1/4 prescaled); used for synchronizing external logic or test measurement. |
Key Features
| Feature | Design Value |
|---|---|
| On-board programming (OBP) | Supports flash reprogramming via SCI boot mode using single 3.3 V supply - eliminates need for external programmers in field updates. |
| Module standby control | Independent enable/disable of SCI, timer, and ADC modules via MSTCR1/MSTCR2 registers - reduces active current to <100 µA per disabled peripheral. |
| Interrupt edge select | IEGR1/IEGR2 registers allow per-pin configuration of rising/falling/both-edge detection on 16 external interrupt sources - enables precise event timing in encoder or switch monitoring. |
| Address break debugging | ABRKCR/BARH/BARL registers support hardware breakpoints on instruction fetch or data access - critical for deterministic real-time debugging without software overhead. |
| Power-down modes | Sleep (CPU stop, peripherals active), Standby (all clocks stopped except RTC), Subsleep (main clock off, subclock active) - extends battery life in portable instrumentation. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F36602BDFP | Successor in RX600 series; 32-bit RXv1 core, 100 MHz, 512 KB flash, but no pin compatibility and requires toolchain migration. | Targets higher-performance applications requiring floating-point math or Ethernet connectivity - not drop-in for DF36024FXV designs. | Select only for new designs needing >2× MIPS and future-proofing; not suitable for legacy board reuse. |
| HD64F36024G | Same H8/36024 family; identical core, memory, and peripheral set, but in 128-pin PQFP package with different pinout and larger footprint. | Used where additional GPIO or expanded peripheral routing is needed - requires PCB redesign due to incompatible package and pin mapping. | Choose only when extra I/O or thermal margin justifies layout change; shares same firmware binary compatibility. |
Compared with R5F36602BDFP and HD64F36024G, DF36024FXV offers optimal balance of proven 16-bit determinism, compact 100-pin LQFP packaging, and full on-chip resource integration - making it the preferred choice for cost-sensitive, space-constrained industrial control upgrades.

FAQ
What is the maximum operating frequency of the DF36024FXV?
The DF36024FXV operates at a maximum frequency of 20 MHz when supplied with 3.3 V ±0.3 V. This frequency is achieved using the on-chip clock pulse generator with an external crystal or ceramic resonator connected to XTAL/EXTAL pins. The DF36024FXV does not support PLL-based frequency multiplication, so system timing is directly derived from the selected resonator or external clock source.
Does the DF36024FXV support in-system programming via serial interface?
Yes, the DF36024FXV supports on-board programming (OBP) through SCI boot mode. When configured in boot mode (using specific pin strapping), the DF36024FXV executes a built-in bootloader that accepts Intel HEX or binary firmware images over SCI0. This allows field firmware updates without requiring external programming hardware or JTAG access.
What ADC resolution and channel count does the DF36024FXV provide?
The DF36024FXV integrates an 8-channel, 10-bit successive-approximation analog-to-digital converter (ADC) with internal sample-and-hold. Each channel supports programmable conversion start triggers (software, timer match, or external pin), and results are stored in dedicated 16-bit result registers. The ADC achieves effective resolution of ≥9.5 bits under typical noise conditions.
Is the DF36024FXV pin-compatible with other members of the H8/36024 Group?
No, the DF36024FXV is not pin-compatible with other H8/36024 Group variants such as HD64F36024G (128-pin PQFP) or H8/36024F (different pinout and package). While all share identical register maps and firmware compatibility, the DF36024FXV's 100-pin LQFP package has unique pin assignments for power, I/O, and peripherals - requiring dedicated PCB layout.
What power management modes are supported by the DF36024FXV?
The DF36024FXV supports three low-power modes: Sleep (CPU halted, peripherals active), Standby (all clocks stopped except optional subclock), and Subsleep (main clock off, subclock running). Entry and exit are controlled via SYSCR1/SYSCR2 registers, with wake-up sources including external interrupts, timer matches, and RTC alarms - enabling µA-range quiescent current in battery-powered applications.
