Product details
Overview
DF36014FYV from Renesas Electronics is a 16-bit single-chip microcomputer in the H8/36014 Group, featuring the H8/300H CPU core with instruction set compatibility to H8/300, 128 KB on-chip ROM, 8 KB RAM, and integrated peripherals including SCI, I2C, timer modules, and A/D converter - deployed in industrial control panels requiring deterministic real-time response.
For engineers reviewing the DF36014FYV datasheet, DF36014FYV pinout, DF36014FYV application, or DF36014FYV equivalent, key selection criteria include its 128 KB flash memory size, 8 KB RAM capacity, 5 V operation, 16 MHz max CPU clock, and support for on-board programming via boot mode using SCI channel 1.
Technical Context
The DF36014FYV implements the H8/300H CPU architecture with 24-bit address space, supporting both little-endian and big-endian data access modes. It integrates system control logic for power-down modes (Sleep, Standby, Subsleep), flash memory controller with erase/program-verify functions, and interrupt handling with configurable edge detection (IEGR1/IEGR2) and priority-based vectoring.
Peripherals include three serial communication interfaces (SCI0–SCI2), one I2C bus interface, 16-bit timer pulse units (TPU), 8-bit timer counter (TMR), and an 8-channel 10-bit successive-approximation A/D converter with sample-and-hold - all mapped into fixed memory-mapped I/O space with dedicated control/status registers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F36614FDFP | Successor in RL78/F14 family; 32 MHz max clock, 128 KB flash, but 8-bit/16-bit mixed architecture and different peripheral register map. | Targets lower-power applications with built-in low-voltage detection and more advanced sleep modes - not drop-in compatible. | Select when migrating to newer Renesas platform with toolchain continuity and extended lifecycle support. |
| HD64F36014G | Same H8/36014 Group silicon; identical core, memory, and peripheral specs - differs only in marking and qualification grade (Standard vs. High Quality). | Identical functional use; HD64F36014G may be rated for higher ambient temperature or extended reliability testing. | Choose HD64F36014G if operating environment exceeds 85°C or requires traceable lot documentation per industrial QA standards. |

FAQ
What is the maximum operating frequency of the DF36014FYV?
The DF36014FYV supports a maximum CPU clock frequency of 16 MHz when operated at 5 V supply voltage. This frequency is achieved using an external crystal or ceramic resonator connected to XTAL/EXTAL pins, with internal clock dividers configured via the system clock generator registers. The DF36014FYV does not include an on-chip PLL, so higher frequencies require external clock sources meeting timing specifications in the Hardware Manual Rev.4.00.
Does the DF36014FYV support in-system programming without external debug hardware?
Yes, the DF36014FYV supports on-board programming via SCI3 (pins P21/RXD and P22/TXD) in boot mode. When the BOOT pin is asserted at reset, the device enters bootloader mode and accepts Intel HEX-formatted firmware images over the serial interface. This capability eliminates dependency on JTAG or E8/E7 emulators for field updates, and is fully documented in Section 7.3.1 of the DF36014FYV Hardware Manual.
What are the power management capabilities of the DF36014FYV?
The DF36014FYV implements three distinct low-power modes: Sleep (CPU stopped, peripherals active), Standby (CPU and most peripherals halted, RAM retained), and Subsleep (ultra-low-current state with selected wake-up sources enabled). Current consumption drops to ≤10 µA in Subsleep mode. Mode transitions are controlled via SYSCR1/SYSCR2 registers, and wake-up can occur from external interrupts, RTC alarm, or A/D conversion completion - all verified in electrical characteristics tables of the DF36014FYV datasheet.
Is the DF36014FYV pin-compatible with other members of the H8/36014 Group?
Yes, the DF36014FYV shares identical pinout and package (100-pin LQFP) with all variants in the H8/36014 Group, including HD64F36014 and HD64F36014G. Pin functions, power/ground allocations, and peripheral mappings are consistent across the group. However, memory size and qualification grade may differ - always verify ROM/RAM configuration and quality grade markings before substitution.
What peripheral interfaces are integrated into the DF36014FYV?
The DF36014FYV integrates three asynchronous serial interfaces (SCI0–SCI2), one synchronous I2C bus interface, an 8-channel 10-bit A/D converter with sample-and-hold, two 16-bit timer pulse units (TPU), one 8-bit timer counter (TMR), and a watchdog timer. All peripherals are memory-mapped and accessible via dedicated control/status registers defined in the DF36014FYV Hardware Manual Rev.4.00, ensuring deterministic access timing and interrupt latency.
