Renesas DF3024FBL25V

Overview

DF3024FBL25V from Renesas Electronics is a 16-bit single-chip microcontroller in the H8/3024F-ZTAT™ family, featuring an H8/300H CPU core with 32-bit internal architecture, 128 KB on-chip flash memory, 4 KB RAM, and integrated peripherals including A/D and D/A converters, timers, SCI, and programmable TPC - used in industrial control systems requiring embedded real-time processing at up to 25 MHz.

For engineers reviewing the DF3024FBL25V datasheet, DF3024FBL25V pinout, DF3024FBL25V application, or DF3024FBL25V equivalent, key selection considerations include flash reprogrammability (100–10,000 cycles), 25 MHz max operating frequency, 48-pin LQFP package, and support for address update modes 1 and 2 in external bus interface configurations.

Technical Context

The DF3024FBL25V implements the H8/300H instruction set with 32-bit internal data paths and supports seven operating modes controlled via MDCR and SYSCR registers. Its peripheral set includes dual 16-bit timers, eight 8-bit timers, watchdog timer, serial communication interface (SCI), and a 10-bit A/D converter with 8 input channels.

Flash memory programming uses on-chip control logic with boot-mode entry at address 0xFFF520; erase time is 100–1200 ms per block and programming time is 10–200 ms per 128-byte unit. Electrical characteristics are specified for 2–25 MHz operation with V_CC = 4.5–5.5 V.

FAQ

What is the maximum operating frequency supported by DF3024FBL25V?

The DF3024FBL25V supports a maximum operating frequency of 25 MHz under specified conditions (V_CC = 4.5–5.5 V, ambient temperature ≤ +75°C). This frequency determines instruction cycle time, peripheral timing resolution, and real-time interrupt latency - all critical for closed-loop control applications. The DF3024FBL25V achieves this using an on-chip PLL-free clock system driven directly by crystal or external oscillator input.

Does DF3024FBL25V include on-chip flash memory, and what are its endurance specifications?

Yes, DF3024FBL25V integrates 128 KB of on-chip single-power-supply flash memory (F-ZTAT™). Its guaranteed endurance is 100 write/erase cycles minimum, with typical performance up to 10,000 cycles at 25°C. Data retention is rated for 10 years when programmed within specification limits. These values are measured per block and apply to the DF3024FBL25V under standard industrial operating conditions.

What package type and pin count does DF3024FBL25V use?

DF3024FBL25V uses a 48-pin LQFP package measuring 7 mm × 7 mm with 0.5 mm lead pitch. This package includes dedicated power/ground pairs, multiplexed address/data bus lines (AD0–AD7, A8–A15), and mode-configurable I/O pins. The pinout is defined in Section 1.3 of the H8/3024 Hardware Manual Rev.2.00 and is specific to the DF3024FBL25V variant.

Can DF3024FBL25V operate with a 3.3 V supply?

No, DF3024FBL25V is specified for operation only within 4.5 V to 5.5 V supply range. It lacks 3.3 V logic compatibility or internal voltage regulation for lower-voltage interfaces. Using 3.3 V violates absolute maximum ratings and will result in undefined behavior or functional failure. For 3.3 V systems, consider Renesas' RX or RA families instead of the DF3024FBL25V.

What development tools are officially supported for DF3024FBL25V firmware development?

Renesas officially supports the High-Performance Embedded Workshop IDE with H8/300 Series C/C++ Compiler (REJ10B0058-0100H) and H8/300 Series Simulator/Debugger (ADE-702-037) for DF3024FBL25V. These tools provide full register-aware debugging, flash programming via on-chip bootloader, and peripheral simulation - all validated for the DF3024FBL25V's H8/300H core and F-ZTAT™ flash architecture.
