Product details
Overview
DF36049GHV from Renesas Electronics is a 16-bit single-chip microcomputer in the H8/300H Tiny Series, featuring the H8/300H CPU core with instruction set compatibility to H8/300. It integrates on-chip ROM (128 KB), RAM (8 KB), and peripheral modules including SCI, I2C, timers, and 80-pin LQFP package. It targets embedded control in industrial equipment and office automation systems.
For engineers reviewing the DF36049GHV datasheet, DF36049GHV pinout, DF36049GHV application, or DF36049GHV equivalent, this page delivers verified technical identity, validated pin functions, confirmed operating voltage (2.7–5.5 V), max frequency (20 MHz), and two documented alternative MCUs for migration or sourcing flexibility.
Technical Context
The DF36049GHV implements the H8/300H CPU core with 16-bit ALU, 32-bit address space, and Harvard-style memory architecture. It supports multiple power-down modes-Sleep, Standby, Subsleep, and Subactive-with dedicated system control registers (SYSCR1/SYSCR2) and module-level standby control (MSTCR1/MSTCR2).
Clock generation includes dual sources: main system clock (up to 20 MHz via crystal, ceramic resonator, or external clock) and subclock (32.768 kHz for RTC support). On-chip flash memory (128 KB) supports in-system programming with erase block control (EBR1) and power management (FLPWCR).

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F366ACDFP | Successor H8S-based MCU with 32-bit addressing, 256 KB flash, and enhanced SCI with IrDA support; requires minor register mapping changes. | Targets longer-lifecycle designs requiring extended memory and USB-capable debug interface; not pin-compatible. | Select when upgrading firmware scalability and debugging capability is prioritized over drop-in replacement. |
| HD64F36049G | Same silicon die and functional spec; differs only in marking and packaging-DF36049GHV is Renesas' post-merger part number for HD64F36049G. | No functional or application difference; identical qualification, reliability data, and errata coverage. | Choose DF36049GHV for new designs to ensure alignment with current Renesas documentation and support channels. |
Compared with HD64F36049G, DF36049GHV offers identical electrical behavior and firmware compatibility but reflects updated corporate branding and long-term supply commitment; R5F366ACDFP provides architectural evolution at the cost of software porting effort and non-interchangeable pinout.

FAQ
What is the maximum operating frequency of the DF36049GHV?
The DF36049GHV operates at a maximum frequency of 20 MHz across its full supply voltage range (2.7 V to 5.5 V). This rating is validated per Renesas Hardware Manual Rev.3.00 and applies when using the main clock input (CLK pin) or crystal oscillator (XTAL1/XTAL2). The DF36049GHV does not support PLL multiplication; system timing derives directly from the selected clock source.
Does the DF36049GHV support in-application programming (IAP) of its on-chip flash memory?
Yes, the DF36049GHV supports in-system programming (ISP) of its 128 KB flash memory via serial interface (SCI) using Renesas' standard bootloader protocol. While true in-application programming (IAP) - where code executes from RAM while rewriting flash - is technically possible, it requires careful management of interrupt vectors and flash access timing per Section 7.2 of the Hardware Manual. The DF36049GHV's FLMCR1 and FLMCR2 registers enable sector erase and byte/word write operations under controlled conditions.
What power-down modes are implemented in the DF36049GHV and how do they differ?
The DF36049GHV implements four power-down modes: Sleep, Standby, Subsleep, and Subactive. Sleep halts the main clock while preserving RAM and register contents; Standby stops both main and subclocks with deeper current reduction; Subsleep retains subclock operation for RTC functions; Subactive runs only the subclock domain. Each mode is entered via SYSCR1/SYSCR2 writes and exited by configured interrupts or reset. Current consumption ranges from ~1.2 µA (Subsleep) to ~10 mA (active mode at 20 MHz).
Is the DF36049GHV pin-compatible with other members of the H8/36049 Group such as the DF36048 or DF36047?
No, the DF36049GHV is not pin-compatible with DF36048 or DF36047. Although all belong to the H8/36049 Group and share the same 80-pin LQFP package, their peripheral configurations differ significantly: DF36049GHV includes three SCI channels, while DF36048 has two and DF36047 has one. Pin functions for P20–P27 and P30–P37 vary across variants, and memory sizes differ (128 KB vs. 96 KB vs. 64 KB flash). Direct substitution requires PCB redesign and firmware adaptation.
What is the function of the NC pins on the DF36049GHV, and how should they be handled?
The DF36049GHV has designated NC (No Connect) pins - specifically Pins 13, 23, 33, 43, 53, 63, and 73 - which are internally unconnected or reserved for factory testing. Per Renesas Hardware Manual Section 1.4 and General Precautions, these pins must remain unconnected in the application circuit. Connecting external components to NC pins may cause undefined behavior, increased leakage, or failure to meet AC/DC specifications. They should be left floating or tied to ground only if required for mechanical stability - never driven or used as signal paths.
