Product details
Overview
DF36054FZV from Renesas Electronics is a 16-bit single-chip microcontroller in the H8/36054 Group, featuring the H8/300H CPU core, 128 KB on-chip ROM, 8 KB RAM, and integrated peripherals including SCI, I2C, timer modules, and 8-channel 10-bit ADC. It operates at up to 20 MHz and supports multiple power-down modes for embedded control applications in industrial equipment and office automation.
For engineers reviewing the DF36054FZV datasheet, DF36054FZV pinout, DF36054FZV application, or DF36054FZV equivalent, key selection criteria include its 100-pin LQFP package, 3.3 V operation, ROM-based firmware execution capability, and support for on-board programming via SCI3 channel 1 (P21/RXD, P22/TXD) in boot mode.
Technical Context
The DF36054FZV implements the H8/300H CPU architecture with instruction set compatibility to the earlier H8/300, enabling legacy code reuse. It integrates a system clock generator supporting crystal, ceramic resonator, or external clock input, plus prescaler S for flexible peripheral clock derivation.
Power management includes four low-power modes - Sleep, Standby, Subsleep, and Subactive - controlled by SYSCR1/SYSCR2 and module-level standby registers (MSTCR1/MSTCR2), allowing selective peripheral shutdown while retaining RAM content and wake-up capability via external interrupt or timer event.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | H8/300H 16-bit RISC core with 20 MHz max operation; enables deterministic real-time control and efficient C compilation. |
| Memory | 128 KB on-chip ROM (flash), 8 KB RAM; supports in-system programming and retains critical variables during low-power modes. |
| ADC | 10-bit successive-approximation ADC with 8 input channels; provides sufficient resolution for sensor interfacing in industrial monitoring. |
| Serial Interfaces | SCI (2 channels), I2C (1 channel); enables communication with UART peripherals, EEPROMs, and sensors without external transceivers. |
| Package | 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch); compatible with standard surface-mount assembly and offers full I/O access for complex control systems. |
| Supply Voltage | 3.3 V ±0.3 V; aligns with modern logic families and reduces power consumption versus 5 V MCUs. |
| Operating Temperature | −20 °C to +75 °C; rated for commercial/industrial environments per Renesas "Standard" quality grade. |
Pinout & Package
DF36054FZV is housed in a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are defined per the H8/36057 Group Hardware Manual Rev. 4.00 (2006), Section 1.3–1.4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC, VSS | Power supply and ground | Dedicated pins for core and I/O power domains; decoupling required per layout guidelines to ensure stable 3.3 V operation. |
| P21/P22 | SCI3 RXD/TXD | Primary interface for on-board programming in boot mode; requires pull-up on P21 and no external driver on P22 during flash programming. |
| P85–P87 | On-chip emulator (E7/E8) interface | Reserved for debug use; unavailable in normal operation unless external hardware bypasses emulator constraints. |
| NMI | Non-maskable interrupt input | Active-low edge-triggered; used for critical fault handling or forced reset recovery; disabled when E7/E8 emulator is active. |
| RESET | Reset input | Active-low synchronous reset; must be held low until power stabilizes and clock oscillates to guarantee defined startup state. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip Flash ROM | 128 KB reprogrammable flash enables field firmware updates and eliminates external memory components. |
| Low-power Modes | Four configurable power states (Sleep, Standby, Subsleep, Subactive) reduce active current to sub-mA levels while preserving context. |
| Integrated ADC | 8-channel 10-bit ADC with internal reference simplifies analog sensor integration without external precision references. |
| Boot Mode Programming | SCI3 channel 1 (P21/P22) supports in-system flash programming without dedicated programmer hardware. |
| Peripheral Clock Control | Module Standby Control Registers (MSTCR1/MSTCR2) allow individual peripheral clock gating to minimize dynamic power. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F36054G | Same die, identical electrical specs; differs only in marking (G suffix denotes lead-free, RoHS-compliant packaging). | No functional difference; suitable for same PCB layouts and firmware binaries. | Select HD64F36054G for new designs requiring RoHS compliance; DF36054FZV remains valid for legacy sourcing. |
| H8/36057 | Pin-compatible upgrade with 256 KB ROM, enhanced SCI features, and extended temperature range (−40 °C to +85 °C). | Supports more complex firmware and harsher environments; requires validation of timing margins in existing designs. | Choose H8/36057 when expanding code size or operating beyond 75 °C ambient; verify clock tree stability under higher load. |
Compared with DF36054FZV, HD64F36054G offers identical functionality in a RoHS-compliant package, while H8/36057 delivers increased memory and extended temperature capability - both require no pinout or schematic changes but differ in firmware compatibility and thermal design margin.

FAQ
What is the maximum operating frequency of the DF36054FZV?
The DF36054FZV supports a maximum CPU clock frequency of 20 MHz, derived from its internal system clock generator using an external crystal, ceramic resonator, or clock source. This frequency enables real-time execution of control algorithms with predictable interrupt latency and deterministic bus timing, consistent across all operating modes except low-power states where clocks are gated.
Does the DF36054FZV support in-system programming (ISP)?
Yes, the DF36054FZV supports in-system programming via its SCI3 channel 1 (pins P21/RXD and P22/TXD) in boot mode. This allows firmware updates without removing the device from the board, using standard UART-level signals and Renesas-provided programming tools. The process requires no external high-voltage programming signals and leverages the on-chip 128 KB flash ROM.
What power management features does the DF36054FZV offer?
The DF36054FZV implements four distinct low-power modes - Sleep, Standby, Subsleep, and Subactive - each with different retention and wake-up capabilities. These are controlled through SYSCR1, SYSCR2, and MSTCR1/MSTCR2 registers. For example, Subactive mode retains RAM and selected peripheral registers while stopping the main CPU clock, enabling wake-up in under 50 µs for time-critical events.
Is the DF36054FZV pin-compatible with other H8/360xx devices?
DF36054FZV is pin-compatible with the HD64F36054 and HD64F36054G variants, sharing identical 100-pin LQFP pinout and function mapping. It is also compatible with the H8/36057 in most configurations, though H8/36057 adds additional peripheral resources and may require minor register initialization adjustments for full feature utilization.
What is the qualified temperature range for the DF36054FZV?
The DF36054FZV is qualified for operation from −20 °C to +75 °C and classified under Renesas' "Standard" quality grade, intended for applications such as office equipment, industrial robots, test and measurement gear, and home appliances. It is not rated for automotive or safety-critical medical use without explicit Renesas written consent.
