Product details
Overview
DF36077LHV from Renesas Electronics is a 16-bit single-chip microcomputer in the H8/36077 Group, featuring the H8/300H CPU core with instruction compatibility to H8/300. It operates at up to 20 MHz, integrates 64 KB on-chip ROM and 4 KB RAM, supports 5 V operation, and targets embedded control in industrial equipment and office automation systems.
For engineers reviewing the DF36077LHV datasheet, DF36077LHV pinout, DF36077LHV application, or DF36077LHV equivalent, this page delivers verified technical context, package mapping, functional specifications, real-world use cases, and validated alternative options for design-in and supply continuity planning.
Technical Context
The DF36077LHV implements the H8/300H CPU architecture with 24-bit address space, supporting both internal ROM/RAM execution and external bus expansion. It includes on-chip peripherals such as 3-channel SCI, 16-bit timer/counters (TMR), watchdog timer (WDT), and low-voltage detection circuitry.
Clock generation is handled by an integrated RC oscillator with trimming capability plus support for external crystal (1–10 MHz) or ceramic resonator. Reset is managed via power-on reset (POR), low-voltage reset (LVR), and external reset pin - all feeding into a dedicated reset controller with configurable delay.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F36077L | Same die, identical pinout and electrical specs; differs only in Renesas part numbering convention and mask ROM content | No functional difference - interchangeable in existing designs using same firmware image | Select HD64F36077L when sourcing from legacy Renesas distribution channels or referencing older documentation |
| H8/36077GF | Same H8/36077 Group silicon but with flash-based program memory instead of mask ROM; requires different programming workflow | Suitable for prototyping and low-volume production where firmware updates are needed; not drop-in for mask-ROM-based systems | Choose H8/36077GF only when field firmware update capability is required and flash endurance meets application needs |
Compared with DF36077LHV, HD64F36077L offers identical functionality with legacy nomenclature, while H8/36077GF trades mask-ROM permanence for flash reprogrammability - impacting BOM cost, development tooling, and long-term firmware maintenance strategy.

FAQ
What is the maximum operating frequency of the DF36077LHV?
The DF36077LHV operates at a maximum frequency of 20 MHz under specified 4.5–5.5 V supply conditions. This timing is guaranteed across commercial temperature range (0°C to +70°C) and enables instruction execution in 50 ns cycles. The DF36077LHV achieves this speed using its on-chip clock generator with external crystal or internal RC oscillator, and all timing parameters in the hardware manual assume this maximum clock rate.
Does the DF36077LHV include on-chip flash or ROM memory?
The DF36077LHV contains 64 KB of mask-programmed ROM and 4 KB of SRAM. It does not include flash memory; program storage is fixed at manufacturing. This distinguishes it from variants like H8/36077GF, which uses flash. The DF36077LHV's ROM is optimized for high-volume, unchanging firmware deployments where security and read-only integrity are priorities.
What package type is used for the DF36077LHV?
The DF36077LHV is housed in an 80-pin LQFP package measuring 14 mm × 14 mm with 0.65 mm lead pitch. This package includes an exposed thermal pad (non-electrical) and conforms to JEDEC MO-220 standards. Pin assignments match the H8/36077 Group hardware manual Rev. 3.00, and the DF36077LHV shares mechanical and thermal characteristics with other members of the group in the same LQFP-80 variant.
Can the DF36077LHV operate from a 3.3 V supply?
No, the DF36077LHV is specified for 4.5 V to 5.5 V operation only. Its I/O structure, internal regulators, and peripheral circuits are designed for 5 V TTL/CMOS compatibility. Attempting to power the DF36077LHV at 3.3 V will result in undefined behavior, failure to initialize, or permanent damage. For 3.3 V systems, consider Renesas' later-generation RL78 or RX families instead of the DF36077LHV.
How many serial communication interfaces does the DF36077LHV support?
The DF36077LHV integrates three independent Serial Communication Interfaces (SCI), each configurable as full-duplex UART with programmable baud rate, parity, and stop bits. These SCIs support asynchronous communication and can be mapped to multiple pin combinations via port function selection. All three are fully operational simultaneously in the DF36077LHV, enabling concurrent host interface, peripheral polling, and debug logging without resource contention.
