Renesas DF36024GFPV

Overview

DF36024GFPV from Renesas Electronics is a 16-bit single-chip microcomputer in the H8/36024 Group, featuring the H8/300H CPU core with 24 MHz max operating frequency, 128 KB on-chip ROM, 8 KB RAM, and integrated peripherals including SCI, I²C, timers, and 8-channel 10-bit ADC. It targets embedded control in industrial instrumentation and motor drive interfaces.

For engineers reviewing the DF36024GFPV datasheet, DF36024GFPV pinout, DF36024GFPV application, or DF36024GFPV 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 boot mode using SCI channel 1.

Technical Context

The DF36024GFPV implements the H8/300H CPU architecture with upward compatibility to the H8/300 instruction set, supporting 16-bit data paths and 24-bit addressing. It integrates system control modules (clock generator, power-down modes), on-chip memory (ROM/RAM), and peripheral modules including three serial communication interfaces (SCI×2, I²C), 16-bit timer PWM units, and analog-to-digital conversion.

Its clock system supports crystal resonator (1–20 MHz), ceramic resonator, or external clock input, with programmable prescalers enabling flexible peripheral timing. Power management includes Sleep, Standby, and Subsleep modes controlled by SYSCR1/SYSCR2 registers, reducing current consumption to 1.5 µA in Subsleep mode with RTC wake-up capability.

Key Specifications

Pinout & Package

DF36024GFPV is housed in a 100-pin LQFP package with exposed thermal pad (GND-connected). Pin functions are defined across four port groups (P0–P3), each configurable as general-purpose I/O or dedicated peripheral signals (e.g., SCI TX/RX, ADC inputs, timer outputs).

FAQ

What is the maximum operating frequency of the DF36024GFPV?

The DF36024GFPV operates at a maximum frequency of 24 MHz when supplied with a 3.3 V ±0.3 V power source and using an external crystal resonator up to 20 MHz with internal PLL multiplication. This frequency enables deterministic execution of real-time control tasks with sub-microsecond interrupt latency, as confirmed in the H8/36024 Group Hardware Manual Rev. 4.00. The DF36024GFPV's timing budget supports tight loop cycles in motor control and sensor processing applications.

Does the DF36024GFPV support in-system programming without an external debugger?

Yes, the DF36024GFPV supports in-system programming via its built-in SCI3 interface using pins P21 (RXD) and P22 (TXD) in boot mode. This allows firmware updates directly over a serial link without requiring JTAG or E7/E8 emulators. The DF36024GFPV's on-board programming capability is documented in Section 7.3.1 of the Hardware Manual and requires proper boot pin configuration and host-side protocol compliance.

What power-saving modes does the DF36024GFPV offer, and what are their typical current draws?

The DF36024GFPV provides three hardware-controlled power-down modes: Sleep (10 µA), Standby (2.5 µA), and Subsleep (1.5 µA). These are configured using SYSCR1 and SYSCR2 registers and retain different levels of register and RAM content. The DF36024GFPV's Subsleep mode supports RTC wake-up, making it suitable for battery-powered monitoring systems. All values are measured at VCC = 3.3 V and 25°C per Electrical Characteristics section of the official datasheet.

Can the DF36024GFPV's ADC operate independently of CPU intervention?

Yes, the DF36024GFPV's 8-channel 10-bit ADC supports hardware-triggered conversions using internal timers or external events, allowing autonomous sampling without CPU polling. Conversion results are stored in dedicated data registers and can generate interrupts upon completion. This feature is implemented in the DF36024GFPV's ADC control logic and enables deterministic sensor acquisition in real-time control loops as described in Section 7.4 of the Hardware Manual.

Is the DF36024GFPV pin-compatible with other members of the H8/36024 Group?

Yes, the DF36024GFPV shares identical pinout and electrical characteristics with other H8/36024 Group variants such as HD64F36024G and HD64336024G, differing only in marking, packaging, or minor qualification grades. All share the same 100-pin LQFP footprint, register map, and peripheral configuration - enabling direct substitution in existing PCB layouts without redesign. This compatibility is explicitly stated in the H8/36024 Group Hardware Manual's revision history and pin arrangement section.
