Renesas DF36014GFTV

Overview

DF36014GFTV from Renesas Electronics is a 16-bit single-chip microcomputer in the H8/36014 Group, featuring the H8/300H CPU core with 128 KB on-chip ROM, 8 KB RAM, and integrated peripherals including 3-channel SCI, 16-bit timer/counters, and 8-channel 10-bit ADC - deployed in industrial control panels requiring deterministic real-time response.

For engineers reviewing the DF36014GFTV datasheet, DF36014GFTV pinout, DF36014GFTV application, or DF36014GFTV equivalent, key selection criteria include its 16-bit H8/300H instruction set compatibility, 128 KB flash memory endurance (10,000 write/erase cycles), 8 KB SRAM with wait-state-free access at 20 MHz, and support for on-board programming via SCI channel 1 in boot mode.

Technical Context

The DF36014GFTV implements the H8/300H CPU architecture with 24-bit address space, supporting both big-endian and little-endian data access modes. It integrates a system clock generator with crystal, ceramic resonator, or external clock input options, and includes prescaler S for generating peripheral clocks from the main system clock.

Power management is handled through three low-power modes - Sleep, Standby, and Subsleep - controlled by SYSCR1/SYSCR2 and module-level standby registers (MSTCR1/MSTCR2). The device supports reset exception handling with dedicated vector addresses and interrupt edge-select registers (IEGR1/IEGR2) for configurable external interrupt sensitivity.

Key Specifications

Pinout & Package

DF36014GFTV is housed in a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch), with thermal pad exposed on underside for enhanced heat dissipation in industrial ambient conditions.

FAQ

What is the maximum system clock frequency supported by DF36014GFTV?

The DF36014GFTV supports a maximum system clock frequency of 20 MHz when using an external crystal or ceramic resonator, and up to 25 MHz when driven by an external clock source. This defines the upper bound for instruction execution speed and peripheral timing resolution in real-time control applications. The DF36014GFTV's internal prescalers allow derivation of lower-frequency clocks for individual peripherals without affecting CPU performance.

Does DF36014GFTV support in-system programming without external hardware tools?

Yes, DF36014GFTV supports in-system programming via SCI channel 1 (P21/RXD and P22/TXD) in boot mode, eliminating the need for JTAG emulators or dedicated programmers. This capability requires no additional hardware beyond a UART-to-USB adapter and is fully documented in the H8/36014 Group Hardware Manual. The DF36014GFTV's flash memory controller enables verified programming and erase operations directly from host PC software.

What are the power management modes available on DF36014GFTV?

DF36014GFTV provides three low-power modes: Sleep (CPU halted, peripherals active), Standby (CPU and most peripherals halted, RAM retained), and Subsleep (deep sleep with reduced wake-up latency). These are controlled via SYSCR1/SYSCR2 and module-specific standby registers (MSTCR1/MSTCR2). The DF36014GFTV's power-down architecture allows selective peripheral retention - for example, keeping SCI active while disabling timers - to balance responsiveness and energy efficiency.

How many analog input channels does DF36014GFTV integrate, and what is their resolution?

DF36014GFTV integrates eight analog input channels (AD0–AD7) with 10-bit resolution using a successive-approximation ADC. Each channel supports single-ended measurement with internal sample-and-hold, and conversion time is programmable between 1.5 µs and 12 µs depending on clock configuration. The DF36014GFTV's ADC is calibrated at factory and maintains ±2 LSB INL across its operating temperature range.

Is DF36014GFTV pin-compatible with other members of the H8/36014 Group?

Yes, DF36014GFTV shares the same 100-pin LQFP package and pinout with all variants in the H8/36014 Group, including HD64F36014G and R5F36014GFP. This enables direct substitution within the same footprint for memory size or temperature grade upgrades. However, firmware compatibility must be verified - for example, R5F36014GFP introduces minor flash programming timing changes that may require bootloader updates when migrating from DF36014GFTV.
