Product details
Overview
DF36034FZV from Renesas Electronics is a 16-bit single-chip microcontroller in the H8/36034 Group, featuring the H8/300H CPU core, 128 KB on-chip ROM, 8 KB RAM, and integrated peripherals including 3-channel SCI, 2-channel timer PWM, and 10-bit ADC with 8 channels. It operates at up to 20 MHz and targets embedded control in industrial equipment and office automation.
For engineers reviewing the DF36034FZV datasheet, DF36034FZV pinout, DF36034FZV application, or DF36034FZV equivalent, key selection considerations include its 100-pin LQFP package, 3.3 V operation, ROM-based program storage, and support for on-board programming via SCI3 channel 1 (P21/RXD, P22/TXD) in boot mode.
Technical Context
The DF36034FZV implements the H8/300H CPU architecture with instruction set compatibility to the earlier H8/300, supporting 16-bit data paths and linear 24-bit addressing. It integrates system control modules including clock pulse generators (crystal, ceramic, or external clock input), multiple power-down modes (Sleep, Standby, Subsleep, Subactive), and module standby control for selective peripheral shutdown.
Peripheral integration includes three serial communication interfaces (SCI), two 16-bit timer PWM units with complementary output capability, a 10-bit successive-approximation ADC with 8 input channels and sample-and-hold, and programmable I/O ports with interrupt-on-change and edge-selectable triggering for external interrupts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | H8/300H 16-bit RISC core, upward-compatible with H8/300 instruction set |
| Max Operating Frequency | 20 MHz - determines real-time execution throughput and peripheral timing resolution |
| On-Chip Memory | 128 KB ROM (flash), 8 KB RAM - supports standalone firmware execution without external memory |
| ADC | 10-bit SAR ADC, 8 channels, internal sample-and-hold - enables analog sensor interfacing with ±1 LSB INL |
| PWM Timers | Two 16-bit timer PWM modules, each with complementary output and dead-time insertion - suitable for motor control drive stages |
| Serial Interfaces | Three independent SCI modules - provide asynchronous full-duplex UART functionality for host/device communication |
| Supply Voltage | 3.3 V ±0.3 V - defines compatible power rail design and I/O voltage level requirements |
Pinout & Package
DF36034FZV is housed in a 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch) package with exposed thermal pad. Pin functions are defined per the H8/36034 Group Hardware Manual Rev. 4.00 (2006), including dedicated reset (RES), clock inputs (XIN/XOUT), and multiplexed I/O ports (P0–P11).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RES | Active-low reset input | Asynchronous hardware reset; must be held low ≥1024 cycles after power stabilization |
| XIN / XOUT | Crystal oscillator connection | Supports 1–20 MHz crystal or ceramic resonator; internal oscillator circuit requires external load capacitors |
| P21 / P22 | SCI3 RXD / TXD (channel 1) | Used for on-board programming in boot mode; requires pull-up on P21 for proper mode detection |
| P85–P87 | Emulator debug interface pins | Reserved for E7/E8 on-chip emulator; not available for user I/O during emulation |
| VCC / VSS | Power and ground terminals | Separate analog/digital supply domains - requires decoupling per layout guidelines in Section 5.3.2 |
Key Features
| Feature | Design Value |
|---|---|
| On-chip flash ROM with erase/write control registers | Enables field firmware updates without external programmer; FLMCR1/FLMCR2 govern write timing and protection |
| Four power-down operating modes | Reduces active current to ≤10 µA in Subsleep mode while retaining RAM and register contents |
| Programmable interrupt edge select (IEGR1/IEGR2) | Allows configuration of external interrupt triggers as rising, falling, or both edges per pin group |
| Dedicated SCI3 boot channel | Permits in-system programming via UART using standard terminal tools - no JTAG required |
| Module Standby Control (MSTCR1/MSTCR2) | Disables clocks to unused peripherals (e.g., ADC, timers) to cut dynamic power without software overhead |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F36034G | Same die, green (lead-free) packaging variant; identical electrical specs and pinout | No functional difference; RoHS-compliant version for environmentally regulated production | Select HD64F36034G when lead-free compliance is mandatory per regional directives |
| H8/36054 | Higher memory config: 256 KB ROM, 16 KB RAM; adds CAN controller and extra SCI channel | Required for systems needing CAN bus connectivity or larger firmware footprint | Choose H8/36054 only if CAN interface or >128 KB code space is essential |
Compared with DF36034FZV, HD64F36034G offers identical functionality in RoHS-compliant packaging, while H8/36054 extends capability with CAN and doubled memory - neither is pin-compatible nor drop-in; PCB layout and firmware adaptation are required for either alternative.

FAQ
What is the maximum operating frequency of the DF36034FZV?
The DF36034FZV operates at a maximum frequency of 20 MHz when supplied with a stable 3.3 V ±0.3 V power source and driven by an appropriate crystal or external clock. This frequency governs instruction execution speed, peripheral timing accuracy, and ADC conversion rate. The DF36034FZV's clock pulse generator supports crystal, ceramic resonator, or external clock input configurations as specified in Section 5 of the H8/36034 Group Hardware Manual.
Does the DF36034FZV support in-system programming?
Yes, the DF36034FZV supports in-system programming via its SCI3 channel (P21/RXD and P22/TXD) in boot mode. This allows firmware updates using standard UART tools without requiring external programming hardware. The DF36034FZV datasheet specifies that P21 must be pulled high during reset to enter boot mode, and the process uses the on-chip flash memory controller registers (FLMCR1, FLMCR2) for safe erase and write operations.
What power management modes does the DF36034FZV offer?
The DF36034FZV provides four configurable power-down modes: Sleep, Standby, Subsleep, and Subactive. In Subsleep mode, current consumption drops to ≤10 µA while preserving RAM and register contents. Mode selection is controlled via SYSCR1 and SYSCR2 registers, and transitions are managed through specific instruction sequences. These modes are documented in Section 6 of the H8/36034 Group Hardware Manual and are intended for battery-powered or energy-sensitive applications.
Is the DF36034FZV pin-compatible with other H8/3603x series MCUs?
No, the DF36034FZV is not universally pin-compatible across the H8/3603x series. While it shares the same 100-pin LQFP package with variants like DF36035 and DF36037, pin functions differ significantly - especially for peripheral signals such as SCI, timer outputs, and ADC inputs. The DF36034FZV pin assignment is unique to its feature set and must be verified against the "Pin Functions" table in Section 1.4 of its Hardware Manual before substitution.
What development tools are supported for the DF36034FZV?
The DF36034FZV is supported by Renesas' legacy H8 toolchain, including the H8S/H8/300 Series C/C++ Compiler (REJ10B0058), Simulator/Debugger (REJ10B0211), and High-Performance Embedded Workshop 3 (REJ10B0026). On-chip debugging requires the E7 or E8 emulator, though pins P85–P87 are reserved and unavailable for general I/O during emulation. The DF36034FZV also supports boot-mode UART programming, eliminating dependency on JTAG for basic firmware loading.
