Product details
Overview
DF3062RXI20V from Renesas Electronics is a 16-bit single-chip microcomputer in the H8/3062 Group, featuring an H8/300H CPU core with 32-bit internal architecture, 128 KB on-chip masked ROM, 4 KB RAM, and integrated peripherals including 16-bit/8-bit timers, SCI, A/D and D/A converters, and programmable timing pattern controller (TPC). It operates at up to 20 MHz and targets embedded control systems requiring deterministic real-time response.
For engineers reviewing the DF3062RXI20V datasheet, DF3062RXI20V pinout, DF3062RXI20V application, or DF3062RXI20V equivalent, this page delivers verified technical context, package mapping, functional pin roles, real-world use cases, and validated alternative options for industrial motor control, sensor-based instrumentation, and automotive body electronics design.
Technical Context
The DF3062RXI20V implements the H8/300H instruction set with 32-bit internal data paths, supporting both big-endian and little-endian memory access modes. Its on-chip peripheral suite includes two 16-bit timers (with input capture/output compare), four 8-bit timers, a watchdog timer (WDT), and a serial communication interface (SCI) compatible with UART protocols.
It integrates a 10-bit successive-approximation A/D converter with 8 channels and a 8-bit D/A converter, alongside a programmable timing pattern controller (TPC) for precise waveform generation. The device uses a single 5 V supply and supports external crystal or ceramic resonator clock sources with configurable oscillation settling wait time.

Pinout & Package
DF3062RXI20V is housed in a 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch) package. Pin functions are defined per operating mode (single-chip, expanded bus, or special modes), with dedicated pins for address/data multiplexing, peripheral I/O, and system control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC, VSS | Power supply and ground | Single 5 V supply operation; requires local decoupling capacitors near each VCC pin for noise immunity. |

| Multiple low-power modes | Includes wait, stop, and deep-stop modes; reduces active current to <10 µA while retaining RAM and register state. |
| Peripheral clock gating | Enables selective disabling of unused modules (e.g., SCI, timers) to cut dynamic power consumption. |
| Reset vector configuration | Allows boot from either on-chip ROM or external memory space, supporting flexible system initialization strategies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F3062B | 128 KB on-chip flash memory instead of masked ROM; supports in-system programming and field firmware updates. | Preferred where firmware revision flexibility is required (e.g., prototyping, small-batch OEMs); lacks ROM mask NRE cost advantage. | Select HD64F3062B if iterative development or post-deployment updates are needed; DF3062RXI20V remains optimal for high-volume, fixed-function deployments. |
| H8/3048F-ZTAT | Smaller footprint (80-pin LQFP), 64 KB flash, 2 KB RAM; no on-chip D/A converter or TPC module. | Suitable for simpler control tasks without waveform generation or analog output; lower BOM cost but reduced peripheral integration. | Choose H8/3048F-ZTAT only when application scope excludes DAC use and TPC-driven timing; DF3062RXI20V retains full feature set for complex embedded control. |
Compared with HD64F3062B and H8/3048F-ZTAT, DF3062RXI20V offers the highest peripheral integration (TPC + DAC + 10-bit A/D) in a production-optimized masked-ROM configuration, delivering lowest total cost and highest reliability for volume-manufactured control units with unchanging firmware requirements.

FAQ
What is the maximum operating frequency of the DF3062RXI20V?
The DF3062RXI20V supports a maximum operating frequency of 20 MHz when using an external crystal or ceramic resonator. This frequency is achievable with proper decoupling, stable power supply (5 V ±10%), and adherence to the oscillator settling wait time configuration specified in the hardware manual. At 20 MHz, the DF3062RXI20V delivers a 50 ns instruction cycle time for time-critical control loops.
Does the DF3062RXI20V include an analog-to-digital converter?
Yes, the DF3062RXI20V integrates a 10-bit successive-approximation A/D converter with eight input channels (AN0–AN7). It supports software or timer-triggered conversions, has built-in sample-and-hold, and allows selection of internal or external reference voltage. This A/D converter is fully documented in Section 15 of the H8/3062 Hardware Manual and is usable in all operating modes of the DF3062RXI20V.
What package type is used for the DF3062RXI20V?
The DF3062RXI20V is packaged in a 100-pin LQFP (Low-Profile Quad Flat Package) measuring 14 mm × 14 mm with 0.5 mm lead pitch. This package is RoHS-compliant and designed for surface-mount reflow assembly. Pin assignments-including address/data multiplexing, peripheral I/O, and power-are detailed in Figures 1.2 and 1.3 of the H8/3062 Hardware Manual Rev.6.00.
Can the DF3062RXI20V operate from a single 5 V supply?
Yes, the DF3062RXI20V is specified for single-supply operation at 5.0 V ±10% (4.5 V to 5.5 V). All I/O pins are 5 V-tolerant, and internal regulators derive required core voltages from this supply. No external voltage translation or auxiliary supplies are needed, simplifying power design for DF3062RXI20V-based systems.
Is there a built-in digital-to-analog converter in the DF3062RXI20V?
Yes, the DF3062RXI20V includes a single 8-bit D/A converter with dedicated output pin DA0. It supports voltage-output mode with internal reference, and its output can drive low-impedance loads up to 1 mA. External buffering is recommended for precision applications. The DAC functionality is accessible via the DADR register and is fully supported in the DF3062RXI20V's standard operating modes.
